Not a physicist, but I’m looking to be a physics major next year when I start college, and Andrew has definitely contributed towards the development of my interest in studying physics and physics in general. I’ve always been super curious about... everything really, but over the year or so that I’ve been watching these I’ve been slowly won over... from engineering.
@@guptadagger896 So we should gene-modify bacteria that's only dangerous to people with special neural connections that only theorists have? Sounds pretty good to me.
You reminded me when i did the integral, got a solution, mathematica gave me different solution that was not equivalent to my, and my textbook gave yet another solution that was not coherent with mine and neither with mathematica
I was at the talk you referenced - and I wanted you to know that everyone enjoyed it! There was a lot of laughter and applause that you couldn't hear. In fact, quite a lot of us watch your videos and are fans! Thanks for agreeing to present at our symposium.
"There needs to be more exposition in physics. There needs to be more people talking about what they're going through; what's right around the corner. What can you expect should you choose to pursue a degree in physics?" Besides the memes, this is the main reason I watch your channel. Thanks so much for sharing.
I graduated with my Ph.D in Electrical Engineering last year and the part about “here’s a computer I can’t sign onto so I use my laptop” left me howling with laughter. In the 6.5 years it took me to graduate I never logged into a computer in the lab.
I’m really happy you uploaded when I was at the very bottom. Watching your videos gives me motivation. I’m still at the very begging of being a physics major and I don’t understand anything you said about your research but it sounds way too cool. I hope one day I come back to these videos and figure out what are you talking about
Thanks for carving out enough time to make a new vlog. I can understand (now more than ever considering my own undergrad degree has started) how busy life can get. And honestly, I just wanted to let you know that your videos are the reason that I pushed myself to where I am in academia. Again, thank you so much.
I have been a huge fan of your vlogs since the day I discovered your channel. But your knowledge about physics and the way you present it on youtube is so inspiring. Keep up the good work!
:58 is too relatable. Also we have the same random high school level/freshman year of college bookshelf. It's because grad students defend and realize they have a bunch of textbooks they don't want, so they donate them to the lab. Even though they're oftentimes things literally nobody would ever use.
I'm doing my pre-reqs for taking physics after being out of school for like 5 years. Your descriptions and work are both super interesting and terrifying :D
*me watching all of your videos even though I’m only in my first semester of physics at university and only just covered partial derivates and literally don’t understand half of what you say but love seeing your views and understand of it*: “yup i can see where this all comes from” Also we don’t get to choose the math/physics courses we do until 3rd year of undergrad because Scotland is weird.
eh6794 yeah we don’t get to pick those sort of courses - we just have mathematics for physics a/b, mechanics, waves and optics, E&M, computational physics and experimental physics. We can choose electives but there are none for topics which are further than where we currently are because the physics course prefers to teach us maths rather than the maths department.
Hello Andrew I have finished my physics undergrad and I will be (hopefully) coming to the US or Canada from September 2020. I will be glad to discuss with you the same things you’ve gone through and now I am going through BUT AS AN INTERNATIONAL STUDENT. Thanks for all your tips through all these years!
Wow, TH-cam really just stopped notifying me about your videos and I missed your update 🙃 When you explain your research, I’m immediately reminded that I am an experimentalist haha. It does sound really interesting though. I know that you’re a theorist, but I’d be curious to hear more about the types of labs you did in your experimental physics course. I still find it interesting that you have to take a lab course at NMSU. And, as always, best of luck with Jackson!At my school, we cover most of the book in one semester (our first semester). Hopefully you’re handling the class much better than I did!
i recommend reading up on MHV and Parke-Taylor amplitudes if you haven’t already. as far as i remember it’s for pure yang mills only (CSW, BCFW, extensions have a twistor-like feel though if that’s your thing) but it’s quite remarkable and right up your alley for QCD.
Hahaha...physics is just interesting. U know...i was literally so scared about my upcoming physics exam today and i just watched Andrew's video and im like...meh ive studied enough...whatever happens...happens
bro i love to watch your videos even though i have no idea what is happening lol...my area is in statistics with applications in finance but i love physics and i love even more to see the insane math behind these things....love your stuff
Dude what an awesome vlog, I know you don't have the time to do it often but holy crap that was motivational; seeing you so enthusiastic about your research and approaching it so analytically is tremendously inspirational. Where can I look for the talk you had, I'm sure that it's been recorded somewhere. Either way, I'm a junior undergrad applied maths student and this is what I needed for that push to continue through the night. Cheers!
im not even within the realm of a science major and yet i love watching these vids and have seen a majority of them. testament to ur charm dude, keep bein you!
I really enjoyed this video! Congrats on 100k subscribers btw. I'm in my first semester in undergrad physics and I'm really enjoying it. Picking courses was really helpful to me after watching your channel. I think its really good for people to get an idea for what physics will be like, and I'm really glad channels like yours exist!
I really get those integrals.. I don't do QCD for my research, but semiclassical spin and electron transport and I've been encountering similar difficulties. Good luck!
i just wanna say that watching your videos i got motivated to learn all this stuff all over again and apply to college, i'm currently at second year of highschool and soon to finish it, i'm going into mathematics, so thanks dude love your videos.
Enjoyed the video, as always. Chalk holder? That's next level, Dotson. I wonder if that helps with the endless amounts of chalk that gets on your clothes at the end of the day. Also, does every graduate student have that Clebsch-Gordon table? 😅😅.
So far the chalk holder has changed my life. Definitely less chalk on clothes. And you should see the clebsch gordan table in the particle data group handbook. Same table, but on like a 2 1/2 x 3 1/2 inch sheet of paper.
That was an interesting matrix element you were calculating. What exactly is the result? I'm not sure if I'm just forgetting having done that stuff, but right now, the only types of matrix elements that I remember having calculated were of the form
Ah right so what I do is very similar to the correlation functions you’ve done. The main difference is there may be derivatives of the fields as well instead of just the time ordered products. There is also tensor structure which amounts to looking through the peskin appendix for certain integrals. Mainly in the feynman parameter section.
Cool! I study Nanobiology, which is actually a combination of physics and cell biology/genetics/quantitative biology 😁 (So yeah, a small world, Andrew 😉)

Hey, I love maths and physics, should do math or physics? I personally think I should do physics because i know that there's a lot of math, but I'm not sure I'll get to study all the math I want, anyway, is majoring in physical fun? Is it amusing? I'm in high school and whenever I study physics, maths, and chemistry I feel so damn happy that it feels amazing, I love the challenge and I hope this feeling remains in undergrad and so on
Our prof told us today that when calculating loop integrals for SE one must be careful how to write the input into Mathematica. Because if eg the mass term is in front of the square and also under the square term Mathematica writes it in a stupid way such that it diverges.. But when factorizing it our before it should work even though it is the same equation... Haven't tried it yet but wanted to give you the advice
Gloria Wolkerstorfer well for mine it’s doing the feynman parameter integrals. I was able to calculate the momentum integral if that’s what you’re referring to.
@@AndrewDotsonvideos yes, sorry. I just looked it up now, he mentioned it today when talking about the momentum integral (not mass xp). In our case we replaced the upper integral boundary with the cutoff and after that *this* integral is supposed to converge. It reads sth. like i*couling/4pi integral p^2 d|p_vec| * 1/ sqrt(p^2 + M^2). There he mentioned the preference of some notations in mathematica. But if that's not the issue I might not get your problem :) Good luck
If I recall correctly from one of your previous videos you are in ODU correct? I'll be heading there after I finish community college. It'll be for electrical engineering though. I appreciate the content.
You've done what grad school homework looks like the past 2 semesters and I'm curious as to what graduate E&M looks like and how long your lab reports are. Our advanced lab for undergraduate (redoing experiments like double slit, oil drop, etc.) requires a shit ton and our reports are anywhere between 60-80 pages. Hence I fear a graduate lab.
After you do the fun part of your research, how do you find the energy to write the paper? And how can you get yourself to look at your work and decide that it is finally complete, and you don't have to put any extra work into it before putting it out into the world for a worldwide peer review? Granted my current project is mathematical, but these are two problems I'm having.
I do all of my calculations in latex to begin with so a lot of the writing is already there (about 20 pages of just math doodles and attempts tbh). I have a harder time formatting it than anything. Usually boils down to throwing 10 pages into the appendix which is always heartbreaking lol. As for when is it done, that hasn’t really been up to me. I’m sure I’d have similar struggles if my supervisors weren’t so involved with the process (or at least dictating what the specific goals are).
@@AndrewDotsonvideos I don't have supervisors and I haven't taken a class in what I am publishing in and I never got a chance to take any programming classes before a stroke of bad luck forced me out of school so I'm out of luck on all of those fronts lol. I did have the initial idea given the green light by a professor in the field, but then I found a lot more because I don't know when to stop. I work with prime numbers and I feel like they are a black hole that sucked me in and I can't escape lol. The professor I did talk to is the only professor with a degree in it that I can find in Pittsburgh and she got a little butthurt when I proved her wrong about something involving my work when she disagreed with me so she refuses to speak withe again. So it is just me and the three whiteboards in my room.
Can't wait to go grad school, I hope I can get in somewhere. You really inspire me😊 Did you know exactly what area you wanted to go into at undergraduate level? As PhD is more specialized, and I have loads of interests from Cancer biology, neuroscience, cell and molecular biology etc I don't know if I'll stand a chance of getting accepted when I have too many interests. Applications make it sound like I should already know😂
Oh I really had no idea in undergrad. All I knew is that I wanted to do theory. Having many interests is a good thing. It means some professor researching a topic who doesn't have funding for a student isn't a deal breaker for you because you have many interests and could work with someone else.
@@AndrewDotsonvideos Thank you, that's made me feel a little more at ease😊 Did you also read a lot of research papers in undergrad to know what area you wanted to go further in too?
Hey Andrew, I had a question. As your time as an undergraduate student, on average, how many hours a day/week did you spend on homework or anything related to school?? 🤔
I have a physics course for this semester in the department of chemistry that I'm at and the topic is electromagnetism. On a scale of 1 to 10, how bad is it? Any pointers, any tips you can give me?
If it is the first EM class you take, it should be ok, mainly coulomb's law and all in statics. Make sure you pay attention, because it is more a class on the calculus you have not taken yet or are taking at the SAME time. There are usually some odd tricks that are consistently used to solve these equations, rather than the hack and slash brute force. If it is not the First EM course, you will get maxwell's equations, and if you thought the first was hard...hopefully you have a good teacher. Maxwell's equations make everything you assumed in the first one make sense, but to understand the equations, you need vector calculus and differential equations known well
@@collinbarker Maxwell Equations make me dread my existence. My professor is so useless as well. It's so hard to keep up with it all. I also have to code numerical solutions for laplace equations as well. Currently studying magnetostatics and i have no clue what's going on.....
@@faznaz7455 Best thing to do is to understand what each equation represents, and what parts you ignore due to statics. If you can explain it to your parents or younger sibling such that they understand, you will understand also. Try and find some online resources for it too, since so many people have to take it, info is pretty available, I think Khan Academy has it. Also, try and find some videos that have animations/simulations for what is going on. Magnetostatics is nearly identical to electrostatics, so if you can relate the 2, it is easier to know what equations you need
@@collinbarker I'm currently in 2nd year studying physics and despite getting a 2nd in my first year under the module name "Theory of Electricity" my general understanding of it was all over the place. It was overall fine but not consistent or a thorough understanding by any means. Getting a million equations thrown at your face takes time to get used to but i also find it challenging to understand conceptually compared to my other modules. Also, I'm a heavily intuition based person which means that a lot of my calculations and understanding relies on my intuition of the topic otherwise i would have to memorise accepting facts which is just harder to deal with but not the end of the world. I hope i haven't fallen behind in my studies but this is the only module where i currently have concerns about understanding this module and keeping up to date. I have looked at Khan academy a few times and another youtuber called Michel Van Biezen to try and make sure I'm fine. My exams are in January after the holidays so I'm not too concerned but still not satisfied. Having said that, i have coursework to deal with. Thanks for taking your time anyway. ✌️
@@faznaz7455 Hopefully some of the suggestions I gave you helps, the main issue with physics in general is that they make you memorize stuff to begin with because the "intuitive" route to solve it involves math that comes in 3rd year. Sometimes, it is better to go find the real reason behind why it works, but skip the math for now. Once you understand why, the assumptions are a bit easier to digest. Good luck on the exams.
I have so much of an easy time understanding maths than I do understanding physics, not that it differs so much though, but when I'm struggling to understand a physical concept, I usually look at the math behind it and things start to make a lot of sense and I eventually get it, is it a problem? I mean, is understanding physics through its math really a nice strategy, or is it more recommendable that I focus on reading and imagining the concepts or trying to make some drawings on what's happening?
Is there some equivalent of this integral you could share? I'm doing my first year grad work in math and I've programmed a ton in Mathematica and would love to see what I could make happen on some integral that apparently isn't doing what you think it should be doing. It would be a fun exercise!
@4:17 I can very much relate to that , I feel personnally attacked when my statistics teacher hands in class materials written in times new roman in word 2003

there should be the reversal of the role of energy and mass

You've done what grad school homework looks like the past 2 semesters and I'm curious as to what graduate E&M looks like and how long your lab reports are. Our advanced lab for undergraduate (redoing experiments like double slit, oil drop, etc.) requires a shit ton and our reports are anywhere between 60-80 pages. Hence I fear a graduate lab.
My reports are way less than 60 pages. Probably more along the line of 15 or so.
@@AndrewDotsonvideos That was the length of most of our electronics lab reports with the Arduino so this is uplifting 😅
After you do the fun part of your research, how do you find the energy to write the paper? And how can you get yourself to look at your work and decide that it is finally complete, and you don't have to put any extra work into it before putting it out into the world for a worldwide peer review? Granted my current project is mathematical, but these are two problems I'm having.
I do all of my calculations in latex to begin with so a lot of the writing is already there (about 20 pages of just math doodles and attempts tbh). I have a harder time formatting it than anything. Usually boils down to throwing 10 pages into the appendix which is always heartbreaking lol. As for when is it done, that hasn’t really been up to me. I’m sure I’d have similar struggles if my supervisors weren’t so involved with the process (or at least dictating what the specific goals are).
@@AndrewDotsonvideos I don't have supervisors and I haven't taken a class in what I am publishing in and I never got a chance to take any programming classes before a stroke of bad luck forced me out of school so I'm out of luck on all of those fronts lol. I did have the initial idea given the green light by a professor in the field, but then I found a lot more because I don't know when to stop. I work with prime numbers and I feel like they are a black hole that sucked me in and I can't escape lol. The professor I did talk to is the only professor with a degree in it that I can find in Pittsburgh and she got a little butthurt when I proved her wrong about something involving my work when she disagreed with me so she refuses to speak withe again. So it is just me and the three whiteboards in my room.
"And yes I'm doing it in LaTeX. You can fight me -- I'll fight you harder."
I really regret forgetting how to use LaTeX after I graduated.
Hey Andrew, haven't been watching in a while. Have you retaken qual's yet? Love the work
Not till January
Can't wait to go grad school, I hope I can get in somewhere. You really inspire me😊 Did you know exactly what area you wanted to go into at undergraduate level? As PhD is more specialized, and I have loads of interests from Cancer biology, neuroscience, cell and molecular biology etc I don't know if I'll stand a chance of getting accepted when I have too many interests. Applications make it sound like I should already know😂
Oh I really had no idea in undergrad. All I knew is that I wanted to do theory. Having many interests is a good thing. It means some professor researching a topic who doesn't have funding for a student isn't a deal breaker for you because you have many interests and could work with someone else.
@@AndrewDotsonvideos Thank you, that's made me feel a little more at ease😊 Did you also read a lot of research papers in undergrad to know what area you wanted to go further in too?
Could you make a video about the material you study in your classes and the books you are using for them?
Hey Andrew, I had a question. As your time as an undergraduate student, on average, how many hours a day/week did you spend on homework or anything related to school?? 🤔
I have a physics course for this semester in the department of chemistry that I'm at and the topic is electromagnetism. On a scale of 1 to 10, how bad is it? Any pointers, any tips you can give me?
If it is the first EM class you take, it should be ok, mainly coulomb's law and all in statics. Make sure you pay attention, because it is more a class on the calculus you have not taken yet or are taking at the SAME time. There are usually some odd tricks that are consistently used to solve these equations, rather than the hack and slash brute force.
If it is not the First EM course, you will get maxwell's equations, and if you thought the first was hard...hopefully you have a good teacher. Maxwell's equations make everything you assumed in the first one make sense, but to understand the equations, you need vector calculus and differential equations known well
@@collinbarker Maxwell Equations make me dread my existence. My professor is so useless as well. It's so hard to keep up with it all. I also have to code numerical solutions for laplace equations as well. Currently studying magnetostatics and i have no clue what's going on.....
@@faznaz7455 Best thing to do is to understand what each equation represents, and what parts you ignore due to statics. If you can explain it to your parents or younger sibling such that they understand, you will understand also. Try and find some online resources for it too, since so many people have to take it, info is pretty available, I think Khan Academy has it. Also, try and find some videos that have animations/simulations for what is going on. Magnetostatics is nearly identical to electrostatics, so if you can relate the 2, it is easier to know what equations you need
@@collinbarker I'm currently in 2nd year studying physics and despite getting a 2nd in my first year under the module name "Theory of Electricity" my general understanding of it was all over the place. It was overall fine but not consistent or a thorough understanding by any means. Getting a million equations thrown at your face takes time to get used to but i also find it challenging to understand conceptually compared to my other modules. Also, I'm a heavily intuition based person which means that a lot of my calculations and understanding relies on my intuition of the topic otherwise i would have to memorise accepting facts which is just harder to deal with but not the end of the world. I hope i haven't fallen behind in my studies but this is the only module where i currently have concerns about understanding this module and keeping up to date. I have looked at Khan academy a few times and another youtuber called Michel Van Biezen to try and make sure I'm fine. My exams are in January after the holidays so I'm not too concerned but still not satisfied. Having said that, i have coursework to deal with. Thanks for taking your time anyway. ✌️
@@faznaz7455 Hopefully some of the suggestions I gave you helps, the main issue with physics in general is that they make you memorize stuff to begin with because the "intuitive" route to solve it involves math that comes in 3rd year. Sometimes, it is better to go find the real reason behind why it works, but skip the math for now. Once you understand why, the assumptions are a bit easier to digest. Good luck on the exams.
I have so much of an easy time understanding maths than I do understanding physics, not that it differs so much though, but when I'm struggling to understand a physical concept, I usually look at the math behind it and things start to make a lot of sense and I eventually get it, is it a problem? I mean, is understanding physics through its math really a nice strategy, or is it more recommendable that I focus on reading and imagining the concepts or trying to make some drawings on what's happening?
u gotta do more of these
Is there some equivalent of this integral you could share? I'm doing my first year grad work in math and I've programmed a ton in Mathematica and would love to see what I could make happen on some integral that apparently isn't doing what you think it should be doing. It would be a fun exercise!
aww man weekly phlogs comeback? prob not drew would die of stress lol. P.S nice name doppleganger ;)
YES I HAVE BEEN WAITING FOR THIS
4 more weeks baby!!! 🧠💪
Yussss
You really should teach! I know zero.zero anout physics, but i learn something.
Awesome!!
@4:17 I can very much relate to that , I feel personnally attacked when my statistics teacher hands in class materials written in times new roman in word 2003
Freshman physics major scrub here, is it worth attempting Zee's QFT in a nutshell yet? Ive only taken through calc 3
Loads of love. Enjoy THORsday
hey dude i would love to hear more about your research if you could spice it down for undergrads
You seem grown up. Long time bruh!
