So there's this old joke where a mathematician a physicist and an engineer are trying to measure a building. The mathematician tries to calculate the building using angle of elevation. The physicist drops an egg off the building and calculates the time it takes to fall. The engineer walks up to the owner of the building and asks him how tall it is.
Except that the owner is NOT knowledgeable, or ha$ reason$ for an$wering, or is influenced by city ordinance. Engineers don't know about Galileo (dropping a weight from PISA), or Eratosthenes (who calculated the circumference of the Earth 200 BC ) ! observerms
Also 1999: NASA: A disaster investigation board reports that NASA’s Mars Climate Orbiter burned up in the Martian atmosphere because enjunnears failed to convert units from English to metric ! YES "engineers" misspelled ; hope that somebody will learn and THINK. observerms
For anyone thinking theyre not good enough at math to pursue engineering, id just like to say that as long as you push yourself and are willing to put in hours of studying, you can make it. I had to drop Calculus 1 because I was getting 40s on my tests, retook it and started getting 70s, (still bad) but I pushed myself towards the end of the semester and wound up with an A, after that I got As in calc 2 and calc 3 and currently have an A in differential equations, my point is, its not about being inately smart, its about having the passion to drive yourself to make accomplishments you never deemed possible, so stick with it and staty focused, and you can be succesful in the end. -Mechanical engineering junior who almost dropped out of engineering
Very inspiring comment. But I have to say that being goog at math doesn't make someone smart. I know people that are good at math, but in the other things they are really bad. Against that, I am really really bad at maths, but I am very good at programing, reading comprehension, languages, I almost learn I new language in a week. So, maths doesn't make someone intelligent. There's many diferent ways of being intelligent. I fight everyday with maths(i'm really the worst), but in programing classes I even help the other ones who don't understand, cause this is very easy to me.
I'm not good at math and I build and fly RC airplanes from scratch and I'm also learning to program in arduino. I think people can do what ever they want to do if they love it.
As a real-world practicing engineer, I have to say this video was pretty dead on in terms of how much math you use as an engineer. I graduated in 2007 with a B.S. in Computer Engineering and have worked mostly as a software engineer and more recently as a low-level embedded systems software engineer. The 'core' math classes you will typically take as an engineering major (and this applies for pretty much all degrees with 'Engineering' in the name) are Calc 1, Calc 2, Calc 3, Differential Equations, Linear Algebra, and Probability and Statistics. A lot of times the diff. equ. and linear algebra are taught together in one class, and prob. and stat. are taught together in one class as well. Also note that I'm listing these courses as taught at a standard American university on a semester based schedule. If you are in a different part of the world, and/or on a different class schedule (like a quarter system), your mileage may vary. Also note that you will study some extra 'select' math topics in your engineering courses that are relevant to your specific degree major, and some engineering majors may take a few extra math courses courses from the math department, but the 'core' courses I listed above will get you most of the way there. In terms of math you use in industry, this video is again right on the money. I myself have not used much math in my career, but many of the fundamental concepts I learned in the various math classes I use somewhat regularly. There's been a few times where I used some simple calculus (derivatives specifically) for calculating some simple optimization problems. Most of the math I use is basic statistics for determining rates of failure of systems that we are building, and for projecting estimates for how much time and money a new future project will take. I do work around some other engineers that do data analytics and machine learning which uses quite a bit of statistics and linear algebra. So, depending on what you end up doing in engineering you may use just a little bit of math here and there, or you may end up using quite a bit of math most of the time. One thing I would like to point out is that it is very useful, and impressive to see on a resume of somebody I'm interviewing (hint hint, wink wink...), is when I see somebody list that they are familiar with some basic mathematical software packages. The big one in the engineering industry is Matlab, but there are some decent others like Maple and Sage. If you have some experience with Python programming using some basic math packages, and/or the R programming language (used for statistics) are also very good skills to have and look good on a resume. If you are having trouble with the math, try not to freak out! Everybody struggles with something sooner or later. I strongly recommend you take advantage of any tutoring services you school offers. Try to make friends with people in those same math classes and help each other understand the material (but don't cheat!). One thing I realized, and a lot of people realize, is that you learn more outside of class working together with fellow students in a study room in front of a white board that you typically do in class. The social support of helping each other overcome math difficulties will greatly help you to stay motivated and push through the material. Also, make sure you get plenty of sleep! It's amazing how much lack of sleep degrades your math performance. I also strongly advise young people to start at your local community college or state college. You can usually knock out the first couple years there and then transfer to a major university to finish up. The can greatly reduce the cost of your education this way. I myself have taken math classes at both a university and a community college, and the quality of the courses at the community college were just as good. The key is you just have to stay on top of the material and practice! Math is not a spectator sport, you have to go to practice and play the game if you want to win. You will get out of it what you put into it. Take care, and I hope this helps out some young people. -Chris
I'm an embedded guy, too. The most math I use is algebra and some Boolean (which is specific to CS). What you learn is methods of problem solving and *persistence*. You cannot solve hard problems without persistence - and you will encounter a *lot* of hard problems as an engineer - that is the point of engineering. Your description is spot on.
I just wanna say thanks so much. I took roughly 3 years at a technical colleague doing diesel and welding and I want something better for my life because I enjoy math and how computers work and I have signed back up for school for a computer engineering degree and I appreciate all the information.
I personally think it just makes you much less intimidated to see an algebra problem after you've had a year of calculus and differential equations. :P
NileThe146 all that math sharpens you the more and you get to realise there is nothing you can't learn if you put your mind Into it..no programming language no math problem can be really be hard for you afterwards
I got accepted for a scholarship to do industrial engineering two years ago in 2016. Failed calculus more than once, Received an academic dismissal letter, and I was literally kicked out of school, i didn't let that stop me and now im in the middle of a 2-year aircraft maintenance engineering program specializing in aircraft avionics. - please do not ever think of yourself as a failure because you're not and NEVER GIVE UP!
@@laureandodi28anni66 Aeronautical engineers design planes, maintenance engineers fix planes. To be specific, maintenance engineers overhaul an aircraft to be inspected thoroughly before releasing it to fly again
@Eric Miret I think hes aware of that bro, he just means the coders need to understand the math and physics absolutely inside out. Just look at the Abaqus or Ansys theory documentation to see that 0_0
It's not necessarily software engineers that come up with the math-crunching modules - mathematicians themselves do a lot of the hard work on that front. Software engineers then build the applications that use those modules. Software engineering is one of the least demanding engineering disciplines when it comes to math - at most you'll have to remember some linear algebra stuff, I guess. You can go a whole career without even thinking about an integral.
godthisisannoying I'm a software engineer and it depends a lot in the software you are making, i've been in projects where heavy use of mathematics is needed.
Bill Yang There are exceptions but most of them do have PhDs. Most of them didn't really take up Computer Science in undergrad because CS undergrads usually work as software engineers. They're mostly Physicists/Mathematicians/Engineers with advanced programming skills.
godthisisannoying If you think that SE is nothing about maths then you are so wrong that you can't even comprehend. Who do you think invented modern cryptography and file compression systems. What do you think how do they work?
In my experience, "not good at math" usually translates to not being explained it correctly. Everyone learns a little differently and I honestly believe that everyone can be good at math (within reason - you have to be interested, obviously) if it is explained in a "language" they can understand. People think I am great at math, but I am really not... I just figured out different ways to look at problems. My 10 year old daughter is taking 6th grade advanced math right now, but she initially had the same struggles. Once I showed her there were different ways to approach problems, it was like a light went on and she is well on her way!
math is one of the few courses where you really need a solid understanding of previous material to work off of. If for example you do not understand one chapter, it will prove to be challenging moving forward versus lets say history where if you dont understand a chapter it will not significantly affect the latter chapters. Math is kind of like a chain, if one of the links are loose then the whole structure falls apart. To get "good" at math you need to make sure that you fully understand the concepts before moving forward and this is usually done through practice.
I hated maths, I was bad in it. But now I'm almost done with my master chemical engineering. I had stressful years and I worked very hard for it. After all it was worth it.
TronicBasez are you stupid? Do you become a engineer right after learning how to multiply and divide? Do you become an athlete after 1 day of going to the gym or playing 1 game of basketball? HELL NO
Same haha like when my drink starts going to room temperature or the water in my bath is draining I can’t help but thing of the functions associated with them
I don't usually comment on a video. However, your videos have moved me many times that I simply want to express my appreciation to your channel. You constantly make me enthusiastic about engineering and make me realize how much I take it for granted. Again, thank you! I wish this channel would reach those seeking a degree in the fields you discuss before they make a decision on which career to take as these kinds of information are essential but not taught at school. I sure wish I found this channel before I entered college.
I totally agree with the author, I am an Electrical Engineer with about 15Yrs of experience and I was scared of maths then and I am scared of it now. I did have to work a little harder. Most of the people I found who found Maths harder (in Engineering) were visual people and hardly any prof explained it in visual terms. TH-cam and other places is a good place to start. Ah, and I am an embedded engineer and so far I have not used any of those maths.
I'm a mechanical engineer by training, and have worked as a design engineer, manufacturing/process engineer, engineering manager, and am currently a plant manager. When people talk about engineering they often forget the manufacturing/process engineers. For me, this work has been much more fun than design engineering because manufacturing engineering can be be much more interdisciplinary, mixing mechanical engineering, electrical engineering, programming, operations management, test and measurement, and other disciplines. But, yes. In general algebra and statistics are of much more practical, everyday value in engineering than is calculus. The other thing I'll say is that learning the math is well-worth the hard work. Comprehension is just not possible without engaging with the math. I'm one of those non-math people who worked twice as hard to get through engineering school, and I'm so glad I didn't give up.
I like to work in a factory with £3000-4000.now I'm a student I couldn't make my choice which subject should I choose or what should I read perfectly.please tellme
I was "bad at math." When I returned to college, I had a D in elementary algebra and a C in intermediate algebra on my transcripts. I got better at math with practice, and I'm now in my senior year of mechanical engineering, shopping for graduate schools. If I can get better at math, so can you. I've discovered that most of the time I can outperform the "smart students" by just working a lot harder than them.
Yup i can relate except I'm not at university yet 😂 I started primary school (Australian equivalent of elementary school) with being bad at math then I eventually practised and gradually improved in high school so thanks for your motivation
Engineer here! This is pretty spot on. Knowing why something works the way it does proves more useful just to check that other people are doing things right. The heavy maths is normally left to computers. You'll get a feel for what a correct answer should look like after a bit though and if the computer throws something different at you it'll raise some red flags and maths may be part of the trouble shooting process. The real question you should be asking is "how good do I need to be at excel?" Very. Excel is an incredible tool. Learn it and love it.
Cookie Mite my guy, excel has way more demons hidden inside then simply spreadsheets. Try math equations, graphing, coding while being in the fucking spread sheets....
This video is a great example of how engineers tend to view "math" pretty much exactly the opposite of how a mathematician would. You use the word "math" almost synonymously with "computation." Most mathematicians don't consider computation to be serious mathematics. An understanding of the fundamental concepts using rigorous logic _is_ math! It would be like someone asking, "How much creative writing will I have to do?" and answering, "Not much. You really don't have to worry about your punctuation most of the time. The computer will do that for you. You will still have to come up with unique and interesting ways to express your ideas. And you'll do that a lot. But as I said, you don't have to worry about your punctuation, so you don't need to do much creative writing." That being said, I think the math curriculum (including in colleges and universities!) needs an overhaul. It hasn't really caught up to our technological age.
Seems like OP has not talked to a lot of mathematicians. Sure lower level mathematics is a lot of computation, but most of university and higher math is about the concepts themselves and how to derive and make new concepts to solve a problem.
I disagree that math education needs an overhaul. It is designed to be general for mathematicians and more applied folks. If you’re serious about engineering, you should love its basis in mathematics as well. Computation is a totally different subject which needs its own class.
@@frankjohnson123 I disagree. I learned alot more studying on Khan academy compared to being in a class with a tenured professor. The math can still be difficult to grasp but it's natural. Professors just have too high standards and give students hard problems when they're barely grasping the basics.
My Major in college was Electro-Mechanical Engineering, Found a job working at a Nuclear Powerplant as a Radiation Technician. Never used any Calculus or Differential Equations, however, I extensively used Chemistry and Linear Algebra.
I was going to say. This guy has a fundamental misunderstanding about what the field of mathmatics is. Some kind of hangup that if you're not doing it on paper, you're not using math.
@Aqil Ahmad saying that crunching numbers is math is like saying performing an experiment is science. Sure, you need to experiment in science but it's the least interesting part and only serves to confirm.
I just found your channel and I'm surprised you don't have more subscribers. This is really good quality information and you've really helped me learn and decide my major
23 years into my engineering career. I’ve yet to use math that a 6th or 7th grader couldn’t do. There would be a lot more great engineers if we didn’t scare people away.
The same way we do today, but with books instead of google. You can't use computers for everything during college, as you need to learn the old fashion way.
Physical models and scaled tests. Engineering is applied science. Make hypothesis and test/validate. How do you think we developed formulas in the beginning?
I'm a Senior studying ME right now. I use calculus and differential equations every day in my upper level engineering and physics classes. But in both my internships (one in manufacturing, one in R&D) I mostly relied on basic concepts about physical behaviors that I learned through doing the fluid flow calculations etc. Rather than writing out the problems, I used knowledge from the math to validate results I was seeing.
20 years into my career, the maths came back. But number theory, not calculus. They didn't teach me that in college. Also discrete statistics. For some problems the software tools simply don't exist and you have to start hitting the text books. In order to be productive, you write the software tool to do the mathematics once you've worked it out. The difference between career and college is that no one is testing you and you have colleagues and the internet to consult with.
I’m currently studying Electrical/Electronic Engineering and your video does perfectly entail all the mathematics that you will certainly encounter during your degree. My first two years of study were in general engineering, taking a mixture of mathematical analysis from different fields of engineering. The mathematics seen in each discipline are somewhat unique in their application, however the fundamentals across the different engineering fields are more or less the same. Personally, I’ve always felt as if I was pretty average at maths. In school, I picked things up farily quickly, but I did have to spend more time learning how the mathematics applied to real world problems. At university, it’s the same; I spend more time learning how to apply the theory to real world applications in my field of study. I’m someone who puts a great deal of time into studying the specifics in how the maths I’ve learnt is applied in differnet engineering applications within Electrical/Electronic Engineering, whether it be in modelling electronic systems, control systems, or circuit analysis (to name a few). The mathematics can be daunting and it does often take time and practise to properly contextualise what is learnt, but the reward once the penny drops is like no other. If you love problem-solving and learning about how the world we live in works, engineering as a discipline is fantastic. I love it and I’m happy to put the time into studies in order to have a successful career in EEE!
If you're thinking about engineering take this from a senior in ME. Calc 2 may be the hardest class you run into. If you can get through that there is no reason why you shouldn't be able to do all of your selected discipline. I have a friend that retook it 4 times, but at the same time I took it once in a 5 week summer semester and passed and so did a lot of my other friends. Also, all the material you learn in engineering builds on itself, so this isn't your average degree where you can learn all the material in a course, regurfitate it on the test and once the class is over you forget it all. No, you will see it again, guaranteed. Study groups can be super beneficial or deteriorating. If your group talks more than actually does work then obviously find another more serious group fast. Sometimes you learn better on your own than a group, you have to figure these things out at the beginning. At the end of the day, you need to look at yourself hard in the mirror and ask yourself. When there is homework do I make an effort to learn the material? When a test is coming up do I put in the necessary amount of time to get a 100% A?(you don't necessarily have to get a 100%, you just have to aim for it and get close). One weird one is, am I able to visually rotate objects and see what that would look like without physically rotating it? Believe it or not this is an important skill you'll need in calc 2 and 3 and other courses. If you have a hard time with this one really thoroughly consider engineering.
I'm a junior product development engineer and the video was pretty bang on in terms of how much math is involved in my job. I definitely use maths on a regular basis but 98% of the time it's not nearly as complex as the stuff I did at university. The calculations I have done so far by hand are generally in the realm of geomtry, simple thermal analysis and stacking dimensional tolerances. Saying this, having learnt and practised the complex maths at uni definitely helps me do my job.
This is one of the best videos I’ve seen on the topic of engineering. I love to know about how and why the world works (on the physics side of things) which is why I’m currently pursuing engineering. Right now I’m about to head in to University (hopefully this damn pandemic ends soon)
As a second year engineering student studying mechanical engineer my biggest piece in advice for getting through the tough classes is that you end goal must outweigh the means. Meaning that whatever you are working to has to be more important than how hard it is to get there.
Second year electrical here, I’m almost done all my calc courses (I, II, and III) and I’ll just say that as long as you have a genuine interest in engineering you’ll enjoy learning most math concepts. If you are lucky enough you’ll get a prof who relates these math concepts and operations to real engineering instances it reminds you what you’re taking these courses for. I’ve never been passionate about math but there are some really cool concepts you’ll learn, especially in calc III. If you’re worried about not being good enough at math for engineering you should know that it’s mostly using the same operations in different ways. If you can get those initial derivative and integral operations down almost the rest of calc builds off of that.
It is true that you may not use much math as an engineer, e.g. as a government civilian engineer, or as a system engineer or project manager. However it is important to keep your mind open to the math concepts you studied in school, and over time they become more intuitive. One thing an engineer must never do is close your mind to math, maybe because you struggled with it in college. An engineer must ask questions in order to find dumb mistakes made by smart people and contribute to the success of a team project. Some big engineering failures were caused by people not asking the dumb question.
I usually never comment on videos, but this one plays really close to home. First of all, I would like to congratulate the maker of this video for the effort and the research that went behind putting all of this together. Great work. I'm a mechanical dynamics engineer working for a mechanical engineering company, I got my bachelors, masters and PhD in the field of mechanical vibrations and as this video points out it was a math heavy course to go through, but as I went up the degree ladder I realized that it was not much about doing the math in the later years but interpreting the math which isn't as difficult as the math itself but difficult in a different manner that requires an intuitive understanding of the system you're designing or troubleshooting and a lot of engineering judgement. As this video points out, among the topics that engineers in the workforce use today one should include "Optimization" as well, it is true that a lot of structural and fluid issues can be tackled by using computer models but if you open a software program and generate a model for a bridge for instance the predictions of that model are not going to be accurate solely because the little connections, bolts, welds play an important role in how the structure behaves and it is not always as easy to model them in a software. Using real structure test data as an input for your models and then optimizing your model to see the same results is the way to go. This requires an intense amount of optimization in addition to a good understanding of the governing parameters that will control how you tune your model. Now, optimization as a college course might be intense but in the workforce it is more about setting up the optimization problem and interpreting the results which is a slightly different if not difficult challenge in itself.
I have to disagree. When we use computers for the math, it's to speed up or automate the math that we are using. "Doing math" does not mean nessesarily "doing math by hand", but really using the relationships between formulas and mathematical concepts to solve a numerical problem within a desired tolerance, and what tools you use are irrelevant.
zombiedude347 Then you are not doing math. Even at my University students from Mathematics or Computer Science are joking around that mechanical and electrical engineering students don't use real math, just because they are using a calculator in exams and and they how to proof so much less.
@@eferrari96 Then you propably talked to undergrads who know nothing about university math. You don't need a calculator in math tests in university because it is no use to you. You are just tackling with concepts and making new concepts to solve the problem. Just because mathematicians in uni rarely solve problems discreetly does not mean physicians are not doing math too.
@@RanEncounter I study applied physics and on an exam we also basically never solve with actual numbers. It's purely mathematical solving and proving formula's and relations. So I would say, if there even is such thing as "real math" physicists are doing real math
I agree with almost everything in this video. The curriculum for engineering is bizarrely heavy in pen and paper math. I have been an engineer for decades, and I have never seen anyone solve a calculus problem by hand. Being skilled at linear algebra, statistics, logarithms etc is super valuable. It is also valuable to be able to use this math in a script or spreadsheet.
Well the thing here is to never stop fighting for ur Goals. When I was in elementary school I was so bad in english ( hint: I'm not from an english speaker country). Then at high school I was determined to learn english no matter what. Now I have some feeling that I can speak it. I was good at math in high school but in College at engineering .I would say I was not the best. I even had to change my univeristy cause well ,let just say that I wasnt really motivated with my develop. This bad episode didnt stop me, I change to another Uni in the same degree and I graduated last year with a decent GPA. This story hasnt stop yet, I even got a job at an American company and event apply for master degree at Germany. Now I'm living in Munich in my first semester of my master in nano electronics (hint 2: yeah we use a lot of math). The whole point of this is no matter how hard or complicated could math or physics sound to you. You just have to focus on your Goals. There would be always someone that would try to make u feel stupid because he is better than you in some subject, but that shoudlnt stop you. We all learn in different ways, you just have to find ur own.
I'm a junior in mechanical engineering. This past summer I did an internship at a medical device manufacturing company. Most of what I did consisted of technical writing, learning to use new software (Autocad, solid edge and mini tab), conducting trainings and presenting. A big project I oversaw was relocating a build area. In doing this I had to use basic geometry related to floor planning. I used geometry to help find efficiencies in my redesign, which provided a greater output, utilizing less space than the current model. The other times in which I really used math, I had to use statistics. I would be given stress-strain data about various tensioning tests and my manager asked me to analyze the data and provide capability analysis. The most surprising part of the internship was that I used very little of the math I had worked so hard to learn. I was like "what the heck, where's all the differential equations??" Best advice I can give is this. Work hard in school, pursue internships, but also don't forget to live a little while you're in college. :)
I'm a third year Mechanical Engineering student however I also have 3 years experience within the field as I have been lucky enough to work in the field whilst doing my degree. Funnily enough depends from job to job. I do alot of design personally which has me working with stresses and heat transfer quite a bit of the time. Funnily enough I have been given Electrical Engineering problems to do as well. They tend to involve more math. But overall, software will do most of the math most of the time. I have done heat transfer calculations by hand a few times for efficiency's sake. 3d trig a few times. But no where near as much as I did or am doing in University.
I hated math; I tried and tried but never loved it..... But it all hit me one day; I started to suck it up and do math and I am good at it but still hate it. . . . . . . . This is a change to what the other people have commented about their love-hate relationship with math. Mine is all give and take.
I am an aerospace major and every time someone tells me they are not a math person I suffer PTSD from all the math that I FORCED myself to learn. Bitch please, only math person in the room is your cpu in your phone. Pathetic excuse imo. You would not go to a gym and try to bench 400lbs on the first day, takes years of working up to it, same shit with math. I am convinced anyone can do it, may take more or less work per person is the only disclaimer I would give but in the end its a lot of work for EVERYONE.
Yep, I am a mech major with Dyslexia. It's hard sometimes but in reality, it's mostly down to effort. As long as you study you can get through anything which is what I have learned. Can't tell you the last time I even have had free time. It will all be worth it in the end though.
The one experience I had at an internship at a plastic injection was design an area to clean the water lines of the molds (sort of how the water lines of an engine work) and the one detail I applied, that wasn't required, was the concepts of headloss. I did a general iteration just to refresh my mind of what what type of properties affected loss of pressure in water circuits, and the reason for this was to determine what kind of pump power and hose size I was going to use. So the way I see it so far is that sometimes it's not required, but if you want to do good, efficient designs, you apply concepts you know.
I'm in 7th grade I don't know this stuff but I want to be a mechanical engineer when I grow up because I love building thing although I don't like math I still want to peruse engineering.
It's been a year since your comment so you should be in 8th grade. I too wasn't good in math till I got to 9th grade. My cousin who was a genius helped me and told me to at least read my class notes everyday and rework the problems that we did in class before going through homework. I did it and from then I was a straight A in math. I'm EE now and barely use the math I took in college because software does a lot and, also many of the things we do are based on what someone else designed before us. Most of the time we have to verify that the previous engineer did it correctly. If you have not done it yet, try my suggestion and see how it goes. Good luck future fellow Eng.
Math in college/university is a lot different than high school, at least personally. If you have a calculus high school class, I suggest you take it. It will give you an idea of the math you'll be doing in post-secondary. To kind of explain it a bit better, you'll be dealing with functions a lot, in both 2 and 3 dimensions. The main concepts are derivatives and integrals. 3Blue1Brown explains these concepts really well, personally. You can watch some of his videos to get an idea of what you'll have to do. And a piece of advice: don't panic if you can't understand some concepts from the get go. Discuss them with your classmates, ask the teacher when he/she is available or use Chegg.
Amazing how accurate this video is, I struggle a lot, I mean A FUCKING LOT, to get my Mechanical Engineering degree, hate every minute on tech institute, and after being on the job and seeing the automotive industry here in Puebla, México I realize I wasnt that off, recently I started to enjoy my carrier, i took a while and I did suffer but and the end it was all fine, if someone all ready did it you can do it, thanks to TH-cam, anda channels as Great Scott, Ave, Electro boom, I started to like it more and more,started to understand what I struggle in my classes, suddendly you have a talented teacher from Germany, Canada, or Iran, and you understand way better, because simple the teachers method wanst for you, but have to keep trying, there is not only one way, there are millions, infinite number of correct ways, dont give up, DONT GIVE UP I suck hard at math by the way
I am currently a junior chemical engineering major at LSU. I have been fortunate enough to have completed 2 co-ops with a major chemical company, and I can say this video was very accurate. I have taken all the math classes mentioned in the video, and yes they apply very heavily in some of my core engineering classes like thermodynamics, fluid mechanics, and heat transfer to name a few. On my co-ops however I never did anything above simple algebra, and honestly unit conversions were most of what I needed to adequately solve problems. As mentioned in the video software will be available to do more complex math, and I was actually able to check the solution some software came up with when designing a heat exchanger and determining the size it needed to be which was really gratifying. What type of engineering you go into also influences heavily the amount of math you will do on the job. A process engineer that designs equipment will definitely run more "engineering" calculations than a production or improvement engineer. However it is highly dependent on the company and position. I hope this helps any of you who are considering an engineering major! P.S. Geaux Tigers!
@@mohammadwwoo Sometimes you have to spend weeks overboard away from your family and some people get some serious stress issues with work overload (usually all this happens when you work at a oil rig). But dont let that shy you away. If you are passionate about it you will enjoy and will make lots of money.
The math in engineering and medicine, surgeons is to make them do every single step right and include every little detail, while physically working. Because when you miss a little detail in these professions, the whole project goes wrong, just like math!
Well I'm no engineer, but I am a draftsman who has worked in both the mechanical engineering and architectural field. I am also familiar with the college engineering math curriculum. My experience in mechanical design was that the engineers I worked with used about 4 or 5 of the same formulas on every project (these were formulas that even as a draftsman I learned to use). If you think about it, whatever company you work for that hires engineers will likely only use a half dozen formulas. The company I worked for made high pressure equipment for everything from oil refineries to NASA. So, the engineers basically use pressure, temperature, and flow rate formulas. Some material strength formulas. Of course we had mechanical engineers and electrical engineers (I think the electrical engineers did more work). I agree with this video. You learn a lot of math in school but don't use it all in the field.
I'm back in college at 32. Looking to get an EE degree. I'm on my third semester. I have 10 years experience in graphic design. My focus is alternative energy and EV. I also bought an Arduino to practice building circuit and to do project.
From the wide gamut of topics that Calculus 1,2,3 provides, I've only found use for some things from Calculus 3: - multivariate functions - partial derivatives - del operator With these, I can define a scalar field _f(x, y, z)_ which can be rendered on a GPU quite efficiently using a technique called "ray marching". This scalar field is usually known as *signed distance field,* since it defines the distances for each point in 3D space from a given origin to the surface of the described solid geometry (spheres, cubes, planes, csg, etc.), where positive values are outside the solid and negative values are on the inside (the opposite is also common). The wikipedia page is more descriptive though. Now lets talk about surface normals, used to apply shading to objects in computer graphics. We use ray marching to obtain the coordinates for when _f(x, y, z) → 0⁺_ If we apply the del operator to this function at those coordinates ( _∇ f(x, y, z)_ ), we get a surface normal. How? Partial derivatives approximated by finite central differences (with h = 0.001). At this point we can, for example, render the solid as glass. It should be noted, there will be rays that never reach the solid; these will instead converge _ad infinitum_ and should be discarded early on. PS: This is a hobby of mine, writing GLSL shaders.
"Now for those who are impatient, let me just summarize this whole video right now!" It seems you care more about efficiency than personal advancement. This is how you spot an engineer.
I was a physics major in college and did research. Basically every professor of mine said that, should you take the research route, there isn't a ton of math that way. Having done research myself, the bulk of my work was doing basic statistical calculations and even then I had excel or R or Python do all the work for me. This video is spot on. Math and Science is very rewarding fields of study, even if you don't end up doing it as a career.
I’m an electrical engineering senior and I’ve had four engineering internships in design/consulting, manufacturing, R&D, and power. Only in the latter two did I need any math. Manufacturing didn’t need any at all, whereas the power utility I whipped my calculator out everyday but that wasn’t true for all the groups in that company. So it varies widely but people will tell you how technically heavy their work gets
Great video.. I am a retired mechanical engineer, and this in fact is how its done.... beyond all that are other factors that even the computer will not tell you...using just the computer can end badly... a few examples: Let us assume the results of any failure will cost 10,000 lives and cost a trillion dollars.... you will run the calcs but you will also then fit extra supports, more bolting etc.. and several other features to insure that could not ever fail. The computer will not tell you that. Only you can assess those issues. For instance, in a nuclear power reactor... putting the absolutely critical reactor cooling pumps in the basement of a building, without noticing that the building is in a flood plane... or an area that could flood at some time. Common sense is senior.
I will say, that as I progress in my engineering courses I find myself looking for the path of least resistance on problems. typically when i try learning new information that is conceptually difficult I try to break it down into easily digestible and manageable portions
Great Video... I graduate in 2000 back in Europe and for the last 18 years I've worked for several companies, mostly automotive. In the times I was in R&D I had to make make extensive use of all the math I learned in university and more, but other then when I was assigned to R&D, the math was more of a tool to understand if results from tests or analysis were reasonable.
Your video excludes the highly skilled software engineers that are writing the software you make reference to in the real world doing those antenna calculations in the background on your computer.
conacal rubdur Oh, so what do you do with a computer science degree then? All that abstract Maths, proving of statements, coming up with creative solutions to abstract problems clearly has some applications later in the job, right?
I’m glad I stumbled across this video this morning. As a retired metallurgical engineer, I find this advice very apropos. I graduated in 1970 at the dawn of the computer era in engineering. I had two classes in computer programming. During my career, I was one of the “weirdos“ who embraced computers, learned to program, and found them to be extremely valuable tools used primarily, in my case, to avoid doing endless,tedious calculations. As far as the math went, I agree with everything in the video. I distinctly recall the two times in my career where I used calculus. In both cases, I used it to validate the calculation I had done by other methods. I didn’t really understand calculus until after I graduated and this book was recommended to me: “Calculus made easy“ by Sylvanus P. Thompson. I also agree with the statement that you don’t have to be a natural at math to get a degree or to be an engineer, though it definitely helps. I’ve known people not very proficient who studied much harder than some of us, graduated, and went on to successful careers. I believe that half of the difficulty people have with math is simply math anxiety!
i can't thank you enough for this video. this is probably the most important video i've seen in my life. it may have just decided my career. so thank you lots :)
Most of my engineering career I haven’t do much math at all. However with my newest job, I’ve specifically been a volunteer to do math heavy stuff because I love heat transfer, vector calc, and differential equations. Some of my knowledge recently has come in very handy when working more esoteric problems.
personally i didn't finish high school but i was able to do Advanced diploma in computer electronic engineering without any refer infact i was better than those who cleared high school , now i am registering to do computer science bachelor and when i graduate, i will do MS in computer engineering and PHD the same later own
I used to struggle a lot with math before college, but that was due to lack of practical knowledge of the subject, I mean.. I could not see what I was calculating once you get into college you start to see math all around you and then it becomes very interesting!
R &D tends to be more math intensive, and can be a lot of fun. Knowing how a formula works, is quite useful when writing code, especially in a robotics environment. I still use calculus in my work. This helps me translate what I desire from the software to machine language.
Today, more specifically a few hours ago, I had a calculus class. The limits were the subject of the class, and I'm not good at calculus. After it, I was worry, because I thought I won't be a good engineer because of being bad at calculus. But after coming home, while eating my lunch this video popped up in my screen on youtube and changed my opinion. Dude thank you so much for this video...
I failed calculus in college and never completed my degree but ended up in electronic engineering anyway. In my 40 year career I never used calculus. I did once run into a a situation where I had to derive a formula to match a curve (from lab tests) but couldn't find a really good match (although x to the power y came close), neither could me coworkers. I referred the problem to the mathematics department of a major university and after a few months they admitted they couldn't find a match either - I felt vindicated LOL! (I ended up using a Basic program on a computer to help the production staff determine what calibration resistor to use.)
@Neal DoubleAA Neal... I don't know you,even I dont know if this is a joke, but dude, if it's true... I'm really sorry bro, what you say is true and it sucks, life isn't fair and it never will be, some people find their place and others are just forgotten...

I'm doing a degree on electrical engineering, and gotta say maths makes to the most part of it. We have Laplace transform in our veins. But afterall i hope this work yields a good job for me.
I watched your video about how much math do you need to know in engineering. I have been a test engineer for about 34 years. Yes they had programming and real calculators back then. The Hp-41cx. YOU picked the calculator. Calculators were a tool not part of a textbook. Graphing? Engineering paper or scientific programming called FORTRAN. Now there’s MATLAB or a host of other high level languages. And that’s what I wanted to talk about. Your videos have a lot of math to describe you concepts in solving real world problems. Your explanation are great and clear and I take notes to go back and understand the Concepts and applications. When I went to college that took 6 yrs part time to get my BS degree in EET THATS TECHNOLOGY NOT TECHNICIAN. My first job in engineering didn’t require a lot of math as you did use simulators. But it showed up know and then. With the internet and wiki there is a wealth of information. Just ask a question about something and you will get an answer. Antenna simulators may have a busy GUI that unless you know what to enter you will be lost. Or it’s outputs are they what you expected? Symbols won’t make sense. So math is the foundation and takes time to get there and say hey this works great for control system design. Sometimes you needed to do it by hand like impedance matching. Or logic diagrams with Boolean logic because one day your tested unit didn’t function right. Different inputs gave wrong outputs per the specifications. Now what? A simulator? No. You created logic diagrams and truth tables to find out the designers programmed the logic array wrong. You learn math from algebra through calculus which anyone can do. Math gives you problem solving skills that will carry on through your career abd your job. You never know what you may be faced with however you will have the confidence and insight of how know what you need to solve or interpret a simulator create models. Simulators are great tools to get the math done but you need to know if it’s in the ballpark of what your expecting. You may work with different disciplines of engineers so mechanics crosses with circuit analysis or magnetics with fluid dynamics. Same differential equations. Some people fear math cause they don’t know if they can grasp it. But if I could do it anyone can do it. Math builds on itself. So dy/dx is like a shorthand way of rates of change at a precise point. Linear algebra and Laplace transforms changed my way of seeing the power behind math. Well enough said for now.
You should be fine. I don't remember personally having to memorize much for my engineering classes. You usually get an equation sheet and just have to know how to apply the formulas properly. You will have to memorize some things but it's not like in english where you have to memorize 50 vocab words you've never heard of before
I'm the same way, and I have a 3.9 GPA with one year remaining until I get my degree in Mechanical Engineering. The only time my bad memory has hindered me was during the prerequisites (Calc 1-3, Diffy Eq, ect...). After you finish the prerequisites most professors will either give you a formula sheet or let you bring your own.
You're okay with engineering. Engineering is not something to memorize but something you need to understand. You wont get too far with Law, I'm afraid.
So there's this old joke where a mathematician a physicist and an engineer are trying to measure a building. The mathematician tries to calculate the building using angle of elevation. The physicist drops an egg off the building and calculates the time it takes to fall. The engineer walks up to the owner of the building and asks him how tall it is.
Engineers are that kinda people.
Except that the owner is NOT knowledgeable, or ha$ reason$ for an$wering, or is influenced by city ordinance.
Engineers don't know about Galileo (dropping a weight from PISA), or Eratosthenes (who calculated the circumference of the Earth 200 BC ) !

Also 1999: NASA: A disaster investigation board reports that NASA’s Mars Climate Orbiter burned up in the Martian atmosphere because enjunnears failed to convert units from English to metric !
YES "engineers" misspelled ; hope that somebody will learn and THINK.

Hammering Hank Actually, the engineer would look at the blueprints.
Hammering Hank bro, dropping something off a building to measure it’s height is the typical highschool problem
For anyone thinking theyre not good enough at math to pursue engineering, id just like to say that as long as you push yourself and are willing to put in hours of studying, you can make it. I had to drop Calculus 1 because I was getting 40s on my tests, retook it and started getting 70s, (still bad) but I pushed myself towards the end of the semester and wound up with an A, after that I got As in calc 2 and calc 3 and currently have an A in differential equations, my point is, its not about being inately smart, its about having the passion to drive yourself to make accomplishments you never deemed possible, so stick with it and staty focused, and you can be succesful in the end.
-Mechanical engineering junior who almost dropped out of engineering
Just technically turned senior status feels good
Very inspiring comment. But I have to say that being goog at math doesn't make someone smart. I know people that are good at math, but in the other things they are really bad. Against that, I am really really bad at maths, but I am very good at programing, reading comprehension, languages, I almost learn I new language in a week.
So, maths doesn't make someone intelligent. There's many diferent ways of being intelligent.
I fight everyday with maths(i'm really the worst), but in programing classes I even help the other ones who don't understand, cause this is very easy to me.
was math discovered or was it invented/man made? *quote from somewhere
Victor Dominguez thank you I needed this
Fuck man. It's thanksgiving break and I keep pushing that physics two book off
I'm not good at math and I build and fly RC airplanes from scratch and I'm also learning to program in arduino. I think people can do what ever they want to do if they love it.

@@Mike-pu9hy well he uses a mixture of aerospace and electrical engineering in his day-to day rc builds.
@@shannahan7 electrical engineering requires a lot of math
Being an engineer and technician is different.
You're programming in C, Arduino is the name of the platform
As a real-world practicing engineer, I have to say this video was pretty dead on in terms of how much math you use as an engineer. I graduated in 2007 with a B.S. in Computer Engineering and have worked mostly as a software engineer and more recently as a low-level embedded systems software engineer.
The 'core' math classes you will typically take as an engineering major (and this applies for pretty much all degrees with 'Engineering' in the name) are Calc 1, Calc 2, Calc 3, Differential Equations, Linear Algebra, and Probability and Statistics. A lot of times the diff. equ. and linear algebra are taught together in one class, and prob. and stat. are taught together in one class as well. Also note that I'm listing these courses as taught at a standard American university on a semester based schedule. If you are in a different part of the world, and/or on a different class schedule (like a quarter system), your mileage may vary.
Also note that you will study some extra 'select' math topics in your engineering courses that are relevant to your specific degree major, and some engineering majors may take a few extra math courses courses from the math department, but the 'core' courses I listed above will get you most of the way there.
In terms of math you use in industry, this video is again right on the money. I myself have not used much math in my career, but many of the fundamental concepts I learned in the various math classes I use somewhat regularly. There's been a few times where I used some simple calculus (derivatives specifically) for calculating some simple optimization problems. Most of the math I use is basic statistics for determining rates of failure of systems that we are building, and for projecting estimates for how much time and money a new future project will take.
I do work around some other engineers that do data analytics and machine learning which uses quite a bit of statistics and linear algebra. So, depending on what you end up doing in engineering you may use just a little bit of math here and there, or you may end up using quite a bit of math most of the time.
One thing I would like to point out is that it is very useful, and impressive to see on a resume of somebody I'm interviewing (hint hint, wink wink...), is when I see somebody list that they are familiar with some basic mathematical software packages. The big one in the engineering industry is Matlab, but there are some decent others like Maple and Sage. If you have some experience with Python programming using some basic math packages, and/or the R programming language (used for statistics) are also very good skills to have and look good on a resume.
If you are having trouble with the math, try not to freak out! Everybody struggles with something sooner or later. I strongly recommend you take advantage of any tutoring services you school offers. Try to make friends with people in those same math classes and help each other understand the material (but don't cheat!). One thing I realized, and a lot of people realize, is that you learn more outside of class working together with fellow students in a study room in front of a white board that you typically do in class. The social support of helping each other overcome math difficulties will greatly help you to stay motivated and push through the material. Also, make sure you get plenty of sleep! It's amazing how much lack of sleep degrades your math performance.
I also strongly advise young people to start at your local community college or state college. You can usually knock out the first couple years there and then transfer to a major university to finish up. The can greatly reduce the cost of your education this way. I myself have taken math classes at both a university and a community college, and the quality of the courses at the community college were just as good. The key is you just have to stay on top of the material and practice! Math is not a spectator sport, you have to go to practice and play the game if you want to win. You will get out of it what you put into it.
Take care, and I hope this helps out some young people.

Chris H thank you for this comment it is really helpful
Chris H very accurate
rhanks you very much I find this comment very helpful
I'm an embedded guy, too. The most math I use is algebra and some Boolean (which is specific to CS).
What you learn is methods of problem solving and *persistence*. You cannot solve hard problems without persistence - and you will encounter a *lot* of hard problems as an engineer - that is the point of engineering.
Your description is spot on.
I just wanna say thanks so much. I took roughly 3 years at a technical colleague doing diesel and welding and I want something better for my life because I enjoy math and how computers work and I have signed back up for school for a computer engineering degree and I appreciate all the information.
I think a big part of the reason you study so much math for an engineering degree is because it teaches you how to think.
I personally think it just makes you much less intimidated to see an algebra problem after you've had a year of calculus and differential equations. :P
NileThe146 all that math sharpens you the more and you get to realise there is nothing you can't learn if you put your mind Into it..no programming language no math problem can be really be hard for you afterwards
Mathematics is known for strengthening your critical thinking.
Mathematics is pure logic.
You might not write much mathematics as an engineer, but you will be reading it in papers and textbooks and you will need to understand it.
I got accepted for a scholarship to do industrial engineering two years ago in 2016. Failed calculus more than once, Received an academic dismissal letter, and I was literally kicked out of school, i didn't let that stop me and now im in the middle of a 2-year aircraft maintenance engineering program specializing in aircraft avionics.

"Software would do the math" poor software engineers that must understand all that math in order to program the software.
Alexeon nah not necessarily.
It's not necessarily software engineers that come up with the math-crunching modules - mathematicians themselves do a lot of the hard work on that front. Software engineers then build the applications that use those modules. Software engineering is one of the least demanding engineering disciplines when it comes to math - at most you'll have to remember some linear algebra stuff, I guess. You can go a whole career without even thinking about an integral.
godthisisannoying I'm a software engineer and it depends a lot in the software you are making, i've been in projects where heavy use of mathematics is needed.

There are exceptions but most of them do have PhDs. Most of them didn't really take up Computer Science in undergrad because CS undergrads usually work as software engineers. They're mostly Physicists/Mathematicians/Engineers with advanced programming skills.

If you think that SE is nothing about maths then you are so wrong that you can't even comprehend. Who do you think invented modern cryptography and file compression systems. What do you think how do they work?
In my experience, "not good at math" usually translates to not being explained it correctly. Everyone learns a little differently and I honestly believe that everyone can be good at math (within reason - you have to be interested, obviously) if it is explained in a "language" they can understand. People think I am great at math, but I am really not... I just figured out different ways to look at problems. My 10 year old daughter is taking 6th grade advanced math right now, but she initially had the same struggles. Once I showed her there were different ways to approach problems, it was like a light went on and she is well on her way!
Andrew Erwin am not good at math but this really interests me so should I take computer science?
Andrew Erwin ø
math is one of the few courses where you really need a solid understanding of previous material to work off of. If for example you do not understand one chapter, it will prove to be challenging moving forward versus lets say history where if you dont understand a chapter it will not significantly affect the latter chapters. Math is kind of like a chain, if one of the links are loose then the whole structure falls apart. To get "good" at math you need to make sure that you fully understand the concepts before moving forward and this is usually done through practice.
What are those different ways to look at problems?Thank you sir

Do you become an athlete after 1 day of going to the gym or playing 1 game of basketball?
HELL NO
very true lol
I view 'math' as simply learning another LANGUAGE ... simply takes 'practice' and diligence.
There is no something like “you will not use calculus in your life”. AFTER CALCULUS I CAN NOT SEE ANYTHING IN THE WORLD AS NOT BEING A FUNCTION
Could you explain how/what you mean?
really that actually sounds fun lol! give us an example havent taken any calc so no idea how the world appears to u
Same haha like when my drink starts going to room temperature or the water in my bath is draining I can’t help but thing of the functions associated with them
agreed its made me feel mathematically woke about the world
Sure but the function is too conplicated everything is chaos
I don't usually comment on a video. However, your videos have moved me many times that I simply want to express my appreciation to your channel. You constantly make me enthusiastic about engineering and make me realize how much I take it for granted. Again, thank you! I wish this channel would reach those seeking a degree in the fields you discuss before they make a decision on which career to take as these kinds of information are essential but not taught at school. I sure wish I found this channel before I entered college.
Thank you for this comment! These are what make it so easy to continue making more videos for you guys. Best of luck with everything.
I totally agree with the author, I am an Electrical Engineer with about 15Yrs of experience and I was scared of maths then and I am scared of it now. I did have to work a little harder.
Most of the people I found who found Maths harder (in Engineering) were visual people and hardly any prof explained it in visual terms. TH-cam and other places is a good place to start. Ah, and I am an embedded engineer and so far I have not used any of those maths.
Abhyuthanam Hello, I'm a high school student who is interested in Electrical Engineering. Can you please explain your job on a daily basis?
Abyuthanam is the electrical ivq diploma accept is it has job market
I'm a mechanical engineer by training, and have worked as a design engineer, manufacturing/process engineer, engineering manager, and am currently a plant manager. When people talk about engineering they often forget the manufacturing/process engineers. For me, this work has been much more fun than design engineering because manufacturing engineering can be be much more interdisciplinary, mixing mechanical engineering, electrical engineering, programming, operations management, test and measurement, and other disciplines.
But, yes. In general algebra and statistics are of much more practical, everyday value in engineering than is calculus. The other thing I'll say is that learning the math is well-worth the hard work. Comprehension is just not possible without engaging with the math. I'm one of those non-math people who worked twice as hard to get through engineering school, and I'm so glad I didn't give up.

Sir is mechanical engineer math hard?
I was "bad at math." When I returned to college, I had a D in elementary algebra and a C in intermediate algebra on my transcripts. I got better at math with practice, and I'm now in my senior year of mechanical engineering, shopping for graduate schools. If I can get better at math, so can you. I've discovered that most of the time I can outperform the "smart students" by just working a lot harder than them.
Yup i can relate except I'm not at university yet 😂
I started primary school (Australian equivalent of elementary school) with being bad at math then I eventually practised and gradually improved in high school so thanks for your motivation
hey, so did you get a job in the field as a mechanical engineer? Any advice on doing so? Like internship or anything?
Engineer here! This is pretty spot on. Knowing why something works the way it does proves more useful just to check that other people are doing things right. The heavy maths is normally left to computers. You'll get a feel for what a correct answer should look like after a bit though and if the computer throws something different at you it'll raise some red flags and maths may be part of the trouble shooting process.
The real question you should be asking is "how good do I need to be at excel?"
Very. Excel is an incredible tool. Learn it and love it.
Excel, like microsoft excel?
Oh no i'd rather go to hell than learning spreadsheets
Cookie Mite my guy, excel has way more demons hidden inside then simply spreadsheets. Try math equations, graphing, coding while being in the fucking spread sheets....
Can I learn google spreadsheets instead? haha
This video is a great example of how engineers tend to view "math" pretty much exactly the opposite of how a mathematician would. You use the word "math" almost synonymously with "computation." Most mathematicians don't consider computation to be serious mathematics. An understanding of the fundamental concepts using rigorous logic _is_ math!
It would be like someone asking, "How much creative writing will I have to do?" and answering, "Not much. You really don't have to worry about your punctuation most of the time. The computer will do that for you. You will still have to come up with unique and interesting ways to express your ideas. And you'll do that a lot. But as I said, you don't have to worry about your punctuation, so you don't need to do much creative writing."
That being said, I think the math curriculum (including in colleges and universities!) needs an overhaul. It hasn't really caught up to our technological age.
well said good sir
oh my god this is it.
Seems like OP has not talked to a lot of mathematicians. Sure lower level mathematics is a lot of computation, but most of university and higher math is about the concepts themselves and how to derive and make new concepts to solve a problem.
I disagree that math education needs an overhaul. It is designed to be general for mathematicians and more applied folks. If you’re serious about engineering, you should love its basis in mathematics as well. Computation is a totally different subject which needs its own class.
@@frankjohnson123 I disagree. I learned alot more studying on Khan academy compared to being in a class with a tenured professor. The math can still be difficult to grasp but it's natural. Professors just have too high standards and give students hard problems when they're barely grasping the basics.
There should be a big old asterisk on this video that says:
* unless your job is to teach or design the software that other engineers use
I'm in the final semester of my undergrad in Mechanical Engineering and I'm really glad that I stumbled upon such an awesome channel
My Major in college was Electro-Mechanical Engineering, Found a job working at a Nuclear Powerplant as a Radiation Technician. Never used any Calculus or Differential Equations, however, I extensively used Chemistry and Linear Algebra.

more like you need math but you don't need calculation. math is not just about calculation
I was going to say. This guy has a fundamental misunderstanding about what the field of mathmatics is. Some kind of hangup that if you're not doing it on paper, you're not using math.
@Aqil Ahmad saying that crunching numbers is math is like saying performing an experiment is science. Sure, you need to experiment in science but it's the least interesting part and only serves to confirm.
oldcowbb agree, it’s also about thinking differently and identifying patterns
Computation is just one piece of mathematics; in its entirety, it’s the study of problem solving!
I just found your channel and I'm surprised you don't have more subscribers. This is really good quality information and you've really helped me learn and decide my major
Thanks for the comment! Glad it's helping
23 years into my engineering career. I’ve yet to use math that a 6th or 7th grader couldn’t do. There would be a lot more great engineers if we didn’t scare people away.
Channels like you will definitly grow trust me keep it up!!!
Thanks! Will definitely keep the videos coming.
definitely when more and more of the youtube community grows up and has to go to college / university
great answers to frequent questions

How tf did engineers do it before computers?
All handwritten from mathematics. It isn't that hard, you just have to make a lot of sketches and diagrams.
Slide rule, compass, rulers, triangles, protractors, french curve, t-square, tech pen, pencil eraser.
The same way we do today, but with books instead of google.
You can't use computers for everything during college, as you need to learn the old fashion way.
Physical models and scaled tests. Engineering is applied science. Make hypothesis and test/validate. How do you think we developed formulas in the beginning?

I'm a Senior studying ME right now. I use calculus and differential equations every day in my upper level engineering and physics classes. But in both my internships (one in manufacturing, one in R&D) I mostly relied on basic concepts about physical behaviors that I learned through doing the fluid flow calculations etc. Rather than writing out the problems, I used knowledge from the math to validate results I was seeing.
I'm in applied mathematics and computer engineering so basically I'm the guy who makes the software 💀
Thank you for answering all my questions about engineering with your amazing content.
20 years into my career, the maths came back. But number theory, not calculus. They didn't teach me that in college. Also discrete statistics. For some problems the software tools simply don't exist and you have to start hitting the text books. In order to be productive, you write the software tool to do the mathematics once you've worked it out. The difference between career and college is that no one is testing you and you have colleagues and the internet to consult with.
I'm Mechanical Engineering student, and I think this video is very useful and motivating, thanks and keep up the good work!
I’m currently studying Electrical/Electronic Engineering and your video does perfectly entail all the mathematics that you will certainly encounter during your degree. My first two years of study were in general engineering, taking a mixture of mathematical analysis from different fields of engineering. The mathematics seen in each discipline are somewhat unique in their application, however the fundamentals across the different engineering fields are more or less the same.
Personally, I’ve always felt as if I was pretty average at maths. In school, I picked things up farily quickly, but I did have to spend more time learning how the mathematics applied to real world problems. At university, it’s the same; I spend more time learning how to apply the theory to real world applications in my field of study.
I’m someone who puts a great deal of time into studying the specifics in how the maths I’ve learnt is applied in differnet engineering applications within Electrical/Electronic Engineering, whether it be in modelling electronic systems, control systems, or circuit analysis (to name a few). The mathematics can be daunting and it does often take time and practise to properly contextualise what is learnt, but the reward once the penny drops is like no other.
If you love problem-solving and learning about how the world we live in works, engineering as a discipline is fantastic. I love it and I’m happy to put the time into studies in order to have a successful career in EEE!
If you're thinking about engineering take this from a senior in ME. Calc 2 may be the hardest class you run into. If you can get through that there is no reason why you shouldn't be able to do all of your selected discipline. I have a friend that retook it 4 times, but at the same time I took it once in a 5 week summer semester and passed and so did a lot of my other friends. Also, all the material you learn in engineering builds on itself, so this isn't your average degree where you can learn all the material in a course, regurfitate it on the test and once the class is over you forget it all. No, you will see it again, guaranteed.
Study groups can be super beneficial or deteriorating. If your group talks more than actually does work then obviously find another more serious group fast.
Sometimes you learn better on your own than a group, you have to figure these things out at the beginning.
At the end of the day, you need to look at yourself hard in the mirror and ask yourself. When there is homework do I make an effort to learn the material? When a test is coming up do I put in the necessary amount of time to get a 100% A?(you don't necessarily have to get a 100%, you just have to aim for it and get close).
One weird one is, am I able to visually rotate objects and see what that would look like without physically rotating it? Believe it or not this is an important skill you'll need in calc 2 and 3 and other courses. If you have a hard time with this one really thoroughly consider engineering.
I'm a junior product development engineer and the video was pretty bang on in terms of how much math is involved in my job. I definitely use maths on a regular basis but 98% of the time it's not nearly as complex as the stuff I did at university. The calculations I have done so far by hand are generally in the realm of geomtry, simple thermal analysis and stacking dimensional tolerances. Saying this, having learnt and practised the complex maths at uni definitely helps me do my job.
this video deserves salute. GREAT VIDEO.
thanks!
This is one of the best videos I’ve seen on the topic of engineering. I love to know about how and why the world works (on the physics side of things) which is why I’m currently pursuing engineering. Right now I’m about to head in to University (hopefully this damn pandemic ends soon)
These type of videos are exactly what shows the nerves of the field/subject and not just talking only on the surface about money, salary and stuff.
As a second year engineering student studying mechanical engineer my biggest piece in advice for getting through the tough classes is that you end goal must outweigh the means. Meaning that whatever you are working to has to be more important than how hard it is to get there.
Second year electrical here, I’m almost done all my calc courses (I, II, and III) and I’ll just say that as long as you have a genuine interest in engineering you’ll enjoy learning most math concepts. If you are lucky enough you’ll get a prof who relates these math concepts and operations to real engineering instances it reminds you what you’re taking these courses for. I’ve never been passionate about math but there are some really cool concepts you’ll learn, especially in calc III. If you’re worried about not being good enough at math for engineering you should know that it’s mostly using the same operations in different ways. If you can get those initial derivative and integral operations down almost the rest of calc builds off of that.
As an enginner who completed his degree. I can say, NOT MUCH
Was there ever a time where you used calculus at all. Like, even to find where the slope of the beam is zero ?
It is true that you may not use much math as an engineer, e.g. as a government civilian engineer, or as a system engineer or project manager. However it is important to keep your mind open to the math concepts you studied in school, and over time they become more intuitive. One thing an engineer must never do is close your mind to math, maybe because you struggled with it in college. An engineer must ask questions in order to find dumb mistakes made by smart people and contribute to the success of a team project. Some big engineering failures were caused by people not asking the dumb question.
I usually never comment on videos, but this one plays really close to home. First of all, I would like to congratulate the maker of this video for the effort and the research that went behind putting all of this together. Great work.
I'm a mechanical dynamics engineer working for a mechanical engineering company, I got my bachelors, masters and PhD in the field of mechanical vibrations and as this video points out it was a math heavy course to go through, but as I went up the degree ladder I realized that it was not much about doing the math in the later years but interpreting the math which isn't as difficult as the math itself but difficult in a different manner that requires an intuitive understanding of the system you're designing or troubleshooting and a lot of engineering judgement.
As this video points out, among the topics that engineers in the workforce use today one should include "Optimization" as well, it is true that a lot of structural and fluid issues can be tackled by using computer models but if you open a software program and generate a model for a bridge for instance the predictions of that model are not going to be accurate solely because the little connections, bolts, welds play an important role in how the structure behaves and it is not always as easy to model them in a software. Using real structure test data as an input for your models and then optimizing your model to see the same results is the way to go. This requires an intense amount of optimization in addition to a good understanding of the governing parameters that will control how you tune your model. Now, optimization as a college course might be intense but in the workforce it is more about setting up the optimization problem and interpreting the results which is a slightly different if not difficult challenge in itself.
I have to disagree. When we use computers for the math, it's to speed up or automate the math that we are using. "Doing math" does not mean nessesarily "doing math by hand", but really using the relationships between formulas and mathematical concepts to solve a numerical problem within a desired tolerance, and what tools you use are irrelevant.
zombiedude347 Then you are not doing math. Even at my University students from Mathematics or Computer Science are joking around that mechanical and electrical engineering students don't use real math, just because they are using a calculator in exams and and they how to proof so much less.
@@eferrari96 Then you propably talked to undergrads who know nothing about university math. You don't need a calculator in math tests in university because it is no use to you. You are just tackling with concepts and making new concepts to solve the problem.
Just because mathematicians in uni rarely solve problems discreetly does not mean physicians are not doing math too.
@@RanEncounter I study applied physics and on an exam we also basically never solve with actual numbers. It's purely mathematical solving and proving formula's and relations.
So I would say, if there even is such thing as "real math" physicists are doing real math
@@squeakybunny2776 So my point still stands.
@@RanEncounter mostly yeah, but you seemed to imply that physicists mainly solve problems discreetly which from experience I have to disagree with
I agree with almost everything in this video. The curriculum for engineering is bizarrely heavy in pen and paper math. I have been an engineer for decades, and I have never seen anyone solve a calculus problem by hand. Being skilled at linear algebra, statistics, logarithms etc is super valuable. It is also valuable to be able to use this math in a script or spreadsheet.
Well the thing here is to never stop fighting for ur Goals. When I was in elementary school I was so bad in english ( hint: I'm not from an english speaker country). Then at high school I was determined to learn english no matter what. Now I have some feeling that I can speak it.
I was good at math in high school but in College at engineering .I would say I was not the best. I even had to change my univeristy cause well ,let just say that I wasnt really motivated with my develop. This bad episode didnt stop me, I change to another Uni in the same degree and I graduated last year with a decent GPA. This story hasnt stop yet, I even got a job at an American company and event apply for master degree at Germany. Now I'm living in Munich in my first semester of my master in nano electronics (hint 2: yeah we use a lot of math).
The whole point of this is no matter how hard or complicated could math or physics sound to you. You just have to focus on your Goals. There would be always someone that would try to make u feel stupid because he is better than you in some subject, but that shoudlnt stop you. We all learn in different ways, you just have to find ur own.
I'm a junior in mechanical engineering. This past summer I did an internship at a medical device manufacturing company. Most of what I did consisted of technical writing, learning to use new software (Autocad, solid edge and mini tab), conducting trainings and presenting. A big project I oversaw was relocating a build area. In doing this I had to use basic geometry related to floor planning. I used geometry to help find efficiencies in my redesign, which provided a greater output, utilizing less space than the current model.
The other times in which I really used math, I had to use statistics. I would be given stress-strain data about various tensioning tests and my manager asked me to analyze the data and provide capability analysis.
The most surprising part of the internship was that I used very little of the math I had worked so hard to learn. I was like "what the heck, where's all the differential equations??"
Best advice I can give is this. Work hard in school, pursue internships, but also don't forget to live a little while you're in college. :)
I'm a third year Mechanical Engineering student however I also have 3 years experience within the field as I have been lucky enough to work in the field whilst doing my degree. Funnily enough depends from job to job. I do alot of design personally which has me working with stresses and heat transfer quite a bit of the time. Funnily enough I have been given Electrical Engineering problems to do as well. They tend to involve more math. But overall, software will do most of the math most of the time. I have done heat transfer calculations by hand a few times for efficiency's sake. 3d trig a few times. But no where near as much as I did or am doing in University.
Dude!!! You just gave me a confidence boost.... And the comments section.... Thank you!!!
Math in engineering was fine for me until I ran into signal processing. Shit hit the fan there bro, it really did.
I suggest you sketch it out...in electric schematics to get a better understanding of signal processing
I hated math; I tried and tried but never loved it..... But it all hit me one day; I started to suck it up and do math and I am good at it but still hate it.

This is a change to what the other people have commented about their love-hate relationship with math.
Mine is all give and take.
I am an aerospace major and every time someone tells me they are not a math person I suffer PTSD from all the math that I FORCED myself to learn.
Bitch please, only math person in the room is your cpu in your phone. Pathetic excuse imo. You would not go to a gym and try to bench 400lbs on the first day, takes years of working up to it, same shit with math. I am convinced anyone can do it, may take more or less work per person is the only disclaimer I would give but in the end its a lot of work for EVERYONE.
this is so true!
The truth has been spoken!
Ben P. lol thanks this comment makes me feel alot better now
Yep, I am a mech major with Dyslexia. It's hard sometimes but in reality, it's mostly down to effort. As long as you study you can get through anything which is what I have learned. Can't tell you the last time I even have had free time. It will all be worth it in the end though.
Erik Lönnrot Thank you. Yes, calc 3 is as far from 'real math' as addition is from calc 3
@Chris H, As a professionally licensed electrical (power) engineer, I agree with you. This video is right on point.
wow thank you soo much you really motivated me.
Glad I could help!
The one experience I had at an internship at a plastic injection was design an area to clean the water lines of the molds (sort of how the water lines of an engine work) and the one detail I applied, that wasn't required, was the concepts of headloss. I did a general iteration just to refresh my mind of what what type of properties affected loss of pressure in water circuits, and the reason for this was to determine what kind of pump power and hose size I was going to use. So the way I see it so far is that sometimes it's not required, but if you want to do good, efficient designs, you apply concepts you know.
I'm in 7th grade I don't know this stuff but I want to be a mechanical engineer when I grow up because I love building thing although I don't like math I still want to peruse engineering.
It's been a year since your comment so you should be in 8th grade. I too wasn't good in math till I got to 9th grade. My cousin who was a genius helped me and told me to at least read my class notes everyday and rework the problems that we did in class before going through homework. I did it and from then I was a straight A in math. I'm EE now and barely use the math I took in college because software does a lot and, also many of the things we do are based on what someone else designed before us. Most of the time we have to verify that the previous engineer did it correctly. If you have not done it yet, try my suggestion and see how it goes. Good luck future fellow Eng.
Math in college/university is a lot different than high school, at least personally. If you have a calculus high school class, I suggest you take it. It will give you an idea of the math you'll be doing in post-secondary.
To kind of explain it a bit better, you'll be dealing with functions a lot, in both 2 and 3 dimensions. The main concepts are derivatives and integrals. 3Blue1Brown explains these concepts really well, personally. You can watch some of his videos to get an idea of what you'll have to do.
And a piece of advice: don't panic if you can't understand some concepts from the get go. Discuss them with your classmates, ask the teacher when he/she is available or use Chegg.
Wish the best to you man

every one is gangsta until they decide to build a software that engineers use to do math
Amazing how accurate this video is, I struggle a lot, I mean A FUCKING LOT, to get my Mechanical Engineering degree, hate every minute on tech institute, and after being on the job and seeing the automotive industry here in Puebla, México I realize I wasnt that off, recently I started to enjoy my carrier, i took a while and I did suffer but and the end it was all fine, if someone all ready did it you can do it, thanks to TH-cam, anda channels as Great Scott, Ave, Electro boom, I started to like it more and more,started to understand what I struggle in my classes, suddendly you have a talented teacher from Germany, Canada, or Iran, and you understand way better, because simple the teachers method wanst for you, but have to keep trying, there is not only one way, there are millions, infinite number of correct ways, dont give up, DONT GIVE UP I suck hard at math by the way
I suck at math and I can't even understand it, yet I chose electrical engineering as my course in college. I just started and boy oh boy.
:')
how is it going? You are a brave man
I am currently a junior chemical engineering major at LSU. I have been fortunate enough to have completed 2 co-ops with a major chemical company, and I can say this video was very accurate. I have taken all the math classes mentioned in the video, and yes they apply very heavily in some of my core engineering classes like thermodynamics, fluid mechanics, and heat transfer to name a few. On my co-ops however I never did anything above simple algebra, and honestly unit conversions were most of what I needed to adequately solve problems.
As mentioned in the video software will be available to do more complex math, and I was actually able to check the solution some software came up with when designing a heat exchanger and determining the size it needed to be which was really gratifying.
What type of engineering you go into also influences heavily the amount of math you will do on the job. A process engineer that designs equipment will definitely run more "engineering" calculations than a production or improvement engineer. However it is highly dependent on the company and position.
I hope this helps any of you who are considering an engineering major!

As an entry level engineer right out of college, this is one of best videos I've ever seen. Great explanation of study vs reality.
Great video, awesome channel.
In physics major, you will already be calculating EM waves in antennas in undergrad from scratch.
The math in engineering and medicine, surgeons is to make them do every single step right and include every little detail, while physically working. Because when you miss a little detail in these professions, the whole project goes wrong, just like math!
Well I'm no engineer, but I am a draftsman who has worked in both the mechanical engineering and architectural field. I am also familiar with the college engineering math curriculum. My experience in mechanical design was that the engineers I worked with used about 4 or 5 of the same formulas on every project (these were formulas that even as a draftsman I learned to use). If you think about it, whatever company you work for that hires engineers will likely only use a half dozen formulas. The company I worked for made high pressure equipment for everything from oil refineries to NASA. So, the engineers basically use pressure, temperature, and flow rate formulas. Some material strength formulas. Of course we had mechanical engineers and electrical engineers (I think the electrical engineers did more work). I agree with this video. You learn a lot of math in school but don't use it all in the field.
yesterday was my first day at an engineering school, i'm excited and scared at the same time...
How your college went?
Thank you. You have no idea how much this helped with my Mechanical Engineering career classes I am suffering with.
I'm back in college at 32. Looking to get an EE degree. I'm on my third semester. I have 10 years experience in graphic design. My focus is alternative energy and EV. I also bought an Arduino to practice building circuit and to do project.
That's great
From the wide gamut of topics that Calculus 1,2,3 provides, I've only found use for some things from Calculus 3:
- multivariate functions
- partial derivatives
- del operator
With these, I can define a scalar field _f(x, y, z)_ which can be rendered on a GPU quite efficiently using a technique called "ray marching".
This scalar field is usually known as *signed distance field,* since it defines the distances for each point in 3D space from a given origin to the surface of the described solid geometry (spheres, cubes, planes, csg, etc.), where positive values are outside the solid and negative values are on the inside (the opposite is also common).
The wikipedia page is more descriptive though.
Now lets talk about surface normals, used to apply shading to objects in computer graphics.
We use ray marching to obtain the coordinates for when _f(x, y, z) → 0⁺_
If we apply the del operator to this function at those coordinates ( _∇ f(x, y, z)_ ), we get a surface normal.
How? Partial derivatives approximated by finite central differences (with h = 0.001).
At this point we can, for example, render the solid as glass.
It should be noted, there will be rays that never reach the solid; these will instead converge _ad infinitum_ and should be discarded early on.
PS: This is a hobby of mine, writing GLSL shaders.
"Now for those who are impatient, let me just summarize this whole video right now!"
It seems you care more about efficiency than personal advancement. This is how you spot an engineer.
I was a physics major in college and did research. Basically every professor of mine said that, should you take the research route, there isn't a ton of math that way. Having done research myself, the bulk of my work was doing basic statistical calculations and even then I had excel or R or Python do all the work for me. This video is spot on. Math and Science is very rewarding fields of study, even if you don't end up doing it as a career.
They don't tell us this
They just say prep for sat, go to a good college, get a good job, and Enjoy....??
I’m an electrical engineering senior and I’ve had four engineering internships in design/consulting, manufacturing, R&D, and power. Only in the latter two did I need any math. Manufacturing didn’t need any at all, whereas the power utility I whipped my calculator out everyday but that wasn’t true for all the groups in that company. So it varies widely but people will tell you how technically heavy their work gets
A depressed engineer here... looking for motivs...hahajaja
Great video.. I am a retired mechanical engineer, and this in fact is how its done.... beyond all that are other factors that even the computer will not tell you...using just the computer can end badly... a few examples:
Let us assume the results of any failure will cost 10,000 lives and cost a trillion dollars.... you will run the calcs but you will also then fit extra supports, more bolting etc.. and several other features to insure that could not ever fail. The computer will not tell you that. Only you can assess those issues.
For instance, in a nuclear power reactor... putting the absolutely critical reactor cooling pumps in the basement of a building, without noticing that the building is in a flood plane... or an area that could flood at some time. Common sense is senior.
Really good video!
Thanks!
I will say, that as I progress in my engineering courses I find myself looking for the path of least resistance on problems. typically when i try learning new information that is conceptually difficult I try to break it down into easily digestible and manageable portions
15:21
Control systems Engineers use maths everyday heavily
Great Video... I graduate in 2000 back in Europe and for the last 18 years I've worked for several companies, mostly automotive. In the times I was in R&D I had to make make extensive use of all the math I learned in university and more, but other then when I was assigned to R&D, the math was more of a tool to understand if results from tests or analysis were reasonable.
Your video excludes the highly skilled software engineers that are writing the software you make reference to in the real world doing those antenna calculations in the background on your computer.
conacal rubdur Oh, so what do you do with a computer science degree then? All that abstract Maths, proving of statements, coming up with creative solutions to abstract problems clearly has some applications later in the job, right?
I’m glad I stumbled across this video this morning. As a retired metallurgical engineer, I find this advice very apropos. I graduated in 1970 at the dawn of the computer era in engineering. I had two classes in computer programming. During my career, I was one of the “weirdos“ who embraced computers, learned to program, and found them to be extremely valuable tools used primarily, in my case, to avoid doing endless,tedious calculations.
As far as the math went, I agree with everything in the video. I distinctly recall the two times in my career where I used calculus. In both cases, I used it to validate the calculation I had done by other methods. I didn’t really understand calculus until after I graduated and this book was recommended to me: “Calculus made easy“ by Sylvanus P. Thompson.
I also agree with the statement that you don’t have to be a natural at math to get a degree or to be an engineer, though it definitely helps. I’ve known people not very proficient who studied much harder than some of us, graduated, and went on to successful careers. I believe that half of the difficulty people have with math is simply math anxiety!
Maths related to science?
i can't thank you enough for this video. this is probably the most important video i've seen in my life. it may have just decided my career. so thank you lots :)
So basically the only engineers that use math are the ones creating the software for engineers.
Most of my engineering career I haven’t do much math at all. However with my newest job, I’ve specifically been a volunteer to do math heavy stuff because I love heat transfer, vector calc, and differential equations. Some of my knowledge recently has come in very handy when working more esoteric problems.
personally i didn't finish high school but i was able to do Advanced diploma in computer electronic engineering without any refer infact i was better than those who cleared high school , now i am registering to do computer science bachelor and when i graduate, i will do MS in computer engineering and PHD the same later own
ok?

no I don't care about his life story and it is unrelated to the topic of the video
That’s good to hear man
I used to struggle a lot with math before college, but that was due to lack of practical knowledge of the subject, I mean.. I could not see what I was calculating once you get into college you start to see math all around you and then it becomes very interesting!
I truly enjoy math, and use it daily.
R &D tends to be more math intensive, and can be a lot of fun. Knowing how a formula works, is quite useful when writing code, especially in a robotics environment. I still use calculus in my work. This helps me translate what I desire from the software to machine language.
Today, more specifically a few hours ago, I had a calculus class. The limits were the subject of the class, and I'm not good at calculus. After it, I was worry, because I thought I won't be a good engineer because of being bad at calculus. But after coming home, while eating my lunch this video popped up in my screen on youtube and changed my opinion. Dude thank you so much for this video...
@Tuong CS I know, but it is hard for me you know. I have to work harder to pass. But thanks god I don't have cal 2 or cal 3.
@Tuong CS Can I ask what is your subject? I mean are you an engineer too?
I failed calculus in college and never completed my degree but ended up in electronic engineering anyway. In my 40 year career I never used calculus. I did once run into a a situation where I had to derive a formula to match a curve (from lab tests) but couldn't find a really good match (although x to the power y came close), neither could me coworkers. I referred the problem to the mathematics department of a major university and after a few months they admitted they couldn't find a match either - I felt vindicated LOL! (I ended up using a Basic program on a computer to help the production staff determine what calibration resistor to use.)

Your video helps.me a LOT :) thank you
You got it, thanks for the comment!
I watched your video about how much math do you need to know in engineering. I have been a test engineer for about 34 years. Yes they had programming and real calculators back then. The Hp-41cx. YOU picked the calculator. Calculators were a tool not part of a textbook. Graphing? Engineering paper or scientific programming called FORTRAN. Now there’s MATLAB or a host of other high level languages. And that’s what I wanted to talk about. Your videos have a lot of math to describe you concepts in solving real world problems. Your explanation are great and clear and I take notes to go back and understand the Concepts and applications. When I went to college that took 6 yrs part time to get my BS degree in EET THATS TECHNOLOGY NOT TECHNICIAN. My first job in engineering didn’t require a lot of math as you did use simulators. But it showed up know and then. With the internet and wiki there is a wealth of information. Just ask a question about something and you will get an answer. Antenna simulators may have a busy GUI that unless you know what to enter you will be lost. Or it’s outputs are they what you expected? Symbols won’t make sense. So math is the foundation and takes time to get there and say hey this works great for control system design. Sometimes you needed to do it by hand like impedance matching. Or logic diagrams with Boolean logic because one day your tested unit didn’t function right. Different inputs gave wrong outputs per the specifications. Now what? A simulator? No. You created logic diagrams and truth tables to find out the designers programmed the logic array wrong. You learn math from algebra through calculus which anyone can do. Math gives you problem solving skills that will carry on through your career abd your job. You never know what you may be faced with however you will have the confidence and insight of how know what you need to solve or interpret a simulator create models. Simulators are great tools to get the math done but you need to know if it’s in the ballpark of what your expecting. You may work with different disciplines of engineers so mechanics crosses with circuit analysis or magnetics with fluid dynamics. Same differential equations. Some people fear math cause they don’t know if they can grasp it. But if I could do it anyone can do it. Math builds on itself. So dy/dx is like a shorthand way of rates of change at a precise point. Linear algebra and Laplace transforms changed my way of seeing the power behind math. Well enough said for now.
I'm good at math but I'm very i mean very bad at memorizing stuff. Can i take engineering????
You should be fine. I don't remember personally having to memorize much for my engineering classes. You usually get an equation sheet and just have to know how to apply the formulas properly. You will have to memorize some things but it's not like in english where you have to memorize 50 vocab words you've never heard of before
I'm the same way, and I have a 3.9 GPA with one year remaining until I get my degree in Mechanical Engineering. The only time my bad memory has hindered me was during the prerequisites (Calc 1-3, Diffy Eq, ect...). After you finish the prerequisites most professors will either give you a formula sheet or let you bring your own.
engineering is not about memorizing it is all about learning
Use Anki
You're okay with engineering. Engineering is not something to memorize but something you need to understand. You wont get too far with Law, I'm afraid.
Good information for getting an idea of what is engeneering, thankyou.
