Oh yeah (infinity sign)% sure i'll enjoy this wow.. in fact i felt a slight thing in my stomach when i've seen the first problem idk i might be crazy but i like theoretical physics :D
why do you have to take physics for health sciences? my girlfriend has to take 2 physics courses for her health science major and i dont understand why
As a physicist, this is 100% accurate! Plan on having the double pendulum question on some exam you take for sure! For our final in mechanics, our teacher came into a room, pulled a quarter out of his pocket, and spun it on the table. He said "Describe this physically", and left the room. Coolest exam I ever took. (Got a 94 on it by the way 😜)
Same here. I looked at the number of marks you get for a problem and my immidiate thought was "This is how much you lose if you f*ck that thing up". On a related note, I had a first-order logic exam today. Went kinda well... I guess.
Ha , I've been having dreams where I turn up not having done any swotting. I wake up sweating, this is after having got a 2:1 degree in Elec. Eng. Tibees, good going. Have you qualified, and if so what career have you followed?
I enjoyed that little note you put in at the end. I didn’t do anything as intense as theoretical physics, but sometimes I look back at my engineering notes, and I feel like I’ve forgotten half of what I learned in uni. It’s a completely different mindset when you’re immersed in it everyday.
you should do a video on how you tackle problems like these. Not the specific mathematical tools and fancy symbols necessarily, but the methodology and thought process used in solving these.
It frustrates me when I spend a lot of time learning a difficult subject only to forget a lot of things i've learned a year after completing the course. I don't think I can pass the same ochem or biochem exams i've taken before now.
My professor told me that it is okay to forget stuff. That is why you take good notes. You just need to understand the topic well enough such that when you revisit those notes, the information will come back faster.
@DooBick yeah, I'm gonna go ahead and guarantee you that no matter how well you *think* you understand a very difficult mathematical concept, you'll never be able to recall it a few years without having seen it. Not everything is basic mathematics. You can't expect the guy who put his life into fluid mechanics to recall the finer details of topology he learned in his undergrad.
I am a Year 2 Physics Student and I have to say that this is a very good explanation for our situation. For other subjects, you answer something for a question. For Physics, they ask you something, you literally spit out a whole essay of equations and explanations for one question. Although Physics is the hardest subject in Science, having an extremely high workload of 1 hard assignment per week per course with questions that require critical, higher-level thinking and intensive study, I still love Physics. It is my dream. And I will never give up. Raise your hand if you are a Physics student.
I'm studying for one of our theoretical physics exams at the moment and i just found your channel. I must say it is very motivational to see other people, who have been were i am now, that have succeeded in what I'm trying to do ^^. Thanks for the motivational help :) ..theoretical physics exams seem to be similar all over the world, although classical mechanics (Lagrange and hamiltonian mechanics) and quantum mechanics are different exams and courses here. I'm only in my third semester so i haven't gotten father than quantum mechanics in the theoretical physics courses ^^' (wich is the second after classical mechanics..next semester will be electrodynamics...maybe the order is different in other countries or at other universities). Greetings from Germany (and sorry for any English mistakes ^^' ) Now I'm going to study with renewed enthusiasm ;)
I loved Special and General Relativity. Lots of Differential Geometry. I rocked that part. QM is great all around. This video made me want to dive deeper. Great on the explanation, don’t ever let your heart sink. Keep on learning.
I'm trying to learn physics on my own, and I think I might be able to handle the classical mechanics questions. Even though I've studied QM on my own as well, those questions are well beyond my skills. I'm glad I don't have to take tests, since I'm doing this purely out of the personal interest.
You really can't continue learn physics (especially quantum physics) without being able to do this test. If you can comfortably do this test, you should be fine getting into modern formulations of physics. Otherwise, you'll be pretty lost for a while.
aakksshhaayy I think your comment applies to every university exam ever set. As a now retired lecturer, my experience was that the students who attended the course were the ones who aced the exams. The students who attended the first couple of lectures and you never saw again were the ones who failed. And only 5% of students who failed did enough remedial work during the summer to pass the resit exam. In fact, passing at resit was so rare, that I still remember the students who actually managed it.
Hahahahahha! I couldn't help but laughing really hard when I saw the Lagrangian for the double pendulum as your first exam question. Just so relateable. That was a computational problem for us when I took Mechanics. We did the linearized version in class as an example, and then we had to simulate the non-linear verson which was tough because there was 1000x more algebra, which isn't hard, but when you add that many more terms, there are going to be tons of mistakes. For mechanics, we had a spring hooked up to atwood's machinese, which was free to rotate, but not move vertically hooked up to another atwood's machine which could move both rotationally and vertically connected to a mass on one side and a spring on the other. Good memories.
Oh hell no. I'm dumb AF and can't do this. Sticking to programming and data analysis. It's still hard but doable for me. Good job to those smarter than me. You're awesome if you can do this stuff. 👍
I agree, it's just about how people see the world and how they want to work on it. Mindset is everything, and courage of course. passion comes along (I hope).
Hey, any book suggestions for an aspiring computer scientist (with a great interest in artificial neural networks/AI)? Plus, books for an aspiring physicist??? And complementary math books????
I dont see many many people commenting and following your videos, but please dont stop making videos because of that. You're going to have the followers that you deserve sooner or later. Your videos are extremely insightful, and amazing. Thank you so much for sharing! And please keep sharing stuff about Physics, Mathematics , and also, you!
After my B.Sc I didn't bother going back to school. But three years later I am shocked at how well I remember these exact questions. I loved mathematical physics but hard to make a living that way ha ha.
one of my friends went deep into studies like this. one of the exams i was told about had one question, and 3 hours to work it. while i don't know what the physics question was, i remember them sweating bullets as to whether they had passed the test. (seems they well) at this level, only the strong survive, my hat is off to you, young lady, you have done well to even be involved in this.
I m a data scientist and i think its awesome to see math being used to model the physical world. always have been using similar math for other purposes
camden parsons Hi. Is the term data scientist have any connotation with university degree? Im in CS, and always heard the term data science. But in my country, there is no specific curicular to be data scientist. Can I ask you pointer what are the differences between data scientist and establish math course like computer science, applied math or Actuarial?
I use to do fine with math and I think that most other degrees and studies lack the simple answer... yes or no, true or false, good or bad, other degrees don't even go this deep they will simply value stuff according to hunches, for instance those in social studies, politics, law, and in a ton of medical studies...
im getting my cs degree too, but most stuff i learn is from youtube or another website. if your interested in data science you should check out kaggle and sentdex
I flunked the only physics class I've ever taken, and it was freshman year of highschool. I clicked on this to see how hard it is but ended up watching a foreign language video.
I remember doing Lagrangian Mechanics when I studied Physics at uni. Deriving the Lagrangian, L, would be relatively easy. Turning the handle on the calculus to actually find the differential equations takes time and is prone to mistakes.
Hey there! Immensely grateful for the video. I'm physics enthusiast and always wanted to take up physics as a major in university. However I ended up taking Computer Science as my major. Your video helped me satiate my long desire of looking at a physics exam paper at a university. Thanks a million !!
I have watched some of your videos the past few days. I feel they are helping me to get a better perspective when choosing what to study next fall and I'm certain my choice will feel a lot more safe thanks to you. So thank you for doing this.
Answering these physics questions make you appear AS IF you had great powers, because you do; Mind over physics. I am hoping to someday acquire this power as well. Thank you.
I think that perturbation theory is probably one of the harder potential barrier QM problems that can be asked for although once you understand delta-function type potentials the problem is straightforward
I’ve read through all the questions featured in the video, and I haven’t found it that hard. I think that after studying a lot and memorizing a bunch of equations and theories, this exam could be easily doable
I took a minor in physics in college. After all of that study of the physical world, the most impactful insight I gained was the realization that I would have hated majoring in physics.
Don't know how I ended up here, but this is cool. I'm a phd student long done with classes, back fond memories of learning these things for the first time. These are classic problems that every undergrad in physics would know how to do, pretty wild that it's all on the same exam though, lots of variety.
Ha ha, I love that NZ accent. Tinsors. Been watching these as a throwback to my own University. I did Math/Physics -> PHD Math though. Love your channel.
undergrade: "it's fine i guess?" finished degree: "yeah i remember smth about smth [...] you could err...alright, let's leave it to the undergrade students"
Wow nicest channel. I was thinking on reviewing some Physics and going deeper on my studies since the most I have is an engineering background. I'm glad I've found your videos
just discovered your channel thanks for the vids. this video was quite insightful, as a BSc in Physics i was expecting GR and QFT on this exam. But to see Chaotic Mechanics, Intermediate Quantum, and Special Relativity. I don't feel so bad that I didn't pursue my dream of being a physics PHD. Frankly, I'm also a bit dissapointed as I feel that I can tackle GR QFT String Theory or any damn theory ... and was dissapointed that they didn't teach any of these as undergraduate level. Now i know that graduate level seems to be weak on the pace as well, although the laboratory and research experience of a grad student is the #1 thing i wish undergrads like myself could have had more of...
3:20 my eyes got drawn towards the equation in the middle and then my brain started melting. I'm glad we have smart people that can understand these kind of things and invent stuff for me to use.
I have my theoretical electrodynamics and special relativity exam tomorrow :"') At least the first task on your exam looks familiar^^ You and your Videos are awesome!!! First thing I 'm going to do after the exam: To watch an other Video :D
I majored in physics and I loved it. But there were three topics I couldn't understand for the life of me. Not because they weren't interesting but just because they were difficult or over cumbersome. Maxwell's equations in their tensor form, scattering theory for quantum mechanics, and all of thermal physics
University exams have a definite pattern and few favorite topics. They ask those topics almost every semester . You do those and you can crack any university exam easily.
I've been out of school for 6 years and glad to know, I'd still feel pretty comfortable with all of these questions except that part c in question 3. I don't recall that theorem at all.
That actually looks kind of fun. I wish I had learned enough already to know where to begin with any of those. I have only a guess of an answer for describing the properties of a chaotic system. And that is just the result of reading some things on chaos theory in general. I cant wait to go back to school but at the same time I'm absolutely petrified. Thanks for sharing. It's always helpful to just be able to take a look at the scale of what might be expected from me at some point. I'd like to be as prepared as possible. Now I just need to figure out how to pay for it lol.
A few years ago, I thought why did I study physics?!!! But now I am happy. You learn math, programming, experiment design, quantum mechanics, chemistry, and a lot more. You can work and change your field in any direction. From applying deep learning algorithms in neural imaging data analysis to building quantum computers, a background in physics will help you.
I don't like it that most people look at this and are scared or give up because it seems to be too hard. Yes, I can tell that it really is hard and physics is no walk in the park. But there is no way to judge this by a simple exam paper. This one is for students who had their lectures and are prepared for questions like these. It would be bad if everybody could solve it just by reading it. It's the same thing as you see an exam paper in French for the first time. No way you can solve it, but that's mostly because you can't speak French. So to motivate every wannabe physicists: Don't give up. You learn this stuff, you learn this language called mathematics. It's still hard, but you can do it.
I hope to see an exam like this soonly. But before, there is lots of study and research to do to enter at a university. But really like the physics, the way it explains our surroundings beyond an exam. Though, it´s a great challenge.
I don't know how I got to this channel, but that looks bonkers. Granted I haven't done physics since High school, I had a mini seizure when she said double pendulum......I think I'll name my puppy lagrangian. Sounds catchy
Hello from Moscow Institute of Physics and Technologies. At university we have a necessarily 5 courses of general physics (Mechanics, thermodynamics, electrodynamics, optics, quantum physics). All exam have a test with difficult tasks and oral answer. At the 3th year we pass the state qualification exam of 5 courses. At second and third year we study Teoretical Mechanics, field theory, quantum mechanics.
I remember that at age 14 or so I was proud of the fact that I never bothered to do the homework examples but remembered the proofs at exam time. I had to go back to the proof to create a method to solve the questions, rather than have learned processes at my disposal. Sadly that means that today at 67 I have none of those learned processes at my disposal. Don't rely on your youthful insights, do the brain "muscle training" and get that stuff so it's built in early on!. The simple parallel is learning the times tables.
I have no idea why I thought this would end up being a joke. On the other hand, I love that this video exists, and wish TH-cam had been around for things like this when I was an undergrad so I could have had a better idea how to choose an emphasis early on.
Does this look like something you would enjoy? 😂
Tibees
I'm still a 1st year undergrad ...
Showed me where I'm heading 😱😱
Yes
Oh yeah (infinity sign)% sure i'll enjoy this wow.. in fact i felt a slight thing in my stomach when i've seen the first problem idk i might be crazy but i like theoretical physics :D
Yes, but I'm a freak. The only class I didn't enjoy was Stat Mech. No thank you...
Tibees no thx
“This exam will take you three hours”
Ok...
“There are four questions”
...
"Question 1: Find the Lagrangian-"
I quit.
Knowing that John weights 110 pound and Mary is 16 years old, calculate the Sun's mass.
Marcus Forte what.????????
The answer is 42
This shows just how much physics channels simplify stuff for their audience.
I'm not a physics student dont know why I watched the whole video.
not a physics student either but I LOVE to learn new things such as this video!
Biology
I'm taking physics for health sciences and it freaking hard, the stuff she is doing is impossible.
why do you have to take physics for health sciences? my girlfriend has to take 2 physics courses for her health science major and i dont understand why
NERD
"Unify the quantum theory with general relativity for 5 marks. Oh, and explain"
As a physicist, this is 100% accurate! Plan on having the double pendulum question on some exam you take for sure!
For our final in mechanics, our teacher came into a room, pulled a quarter out of his pocket, and spun it on the table.
He said "Describe this physically", and left the room. Coolest exam I ever took. (Got a 94 on it by the way 😜)
Prove Fermat's last theorem on the margins or otherwise.
But surely the margin is too small to contain it?
I could prove it but I just don't have the time for it
By applying a result from Wiles (1995). QED.
yeah... yeah yeah yeah i know some of these words
Ilyas Husain you didn't understand the joke man!!!
How well I understood theoretical physics? I had a theoretical degree in physics.
This might just be me, but once you opened that booklet, I got really nervous. Its funny how test anxiety hits you just by looking at one O.o
I feel the same way when ever I have to leave my house. The heck is wrong with my brain?
Same here. I looked at the number of marks you get for a problem and my immidiate thought was "This is how much you lose if you f*ck that thing up".
On a related note, I had a first-order logic exam today. Went kinda well... I guess.
it hit me as soon as I saw how difficult those questions were, remember looking at papers and not knowing shit in my childhood.
I immediately started looking for the q's I know and the points you get for em.. my way of reducing test anxiety
Ha , I've been having dreams where I turn up not having done any swotting.
I wake up sweating, this is after having got a 2:1 degree in Elec. Eng.
Tibees, good going.
Have you qualified, and if so what career have you followed?
I enjoyed that little note you put in at the end. I didn’t do anything as intense as theoretical physics, but sometimes I look back at my engineering notes, and I feel like I’ve forgotten half of what I learned in uni. It’s a completely different mindset when you’re immersed in it everyday.
you should do a video on how you tackle problems like these. Not the specific mathematical tools and fancy symbols necessarily, but the methodology and thought process used in solving these.
Id get 0 marks from this test
It frustrates me when I spend a lot of time learning a difficult subject only to forget a lot of things i've learned a year after completing the course. I don't think I can pass the same ochem or biochem exams i've taken before now.
my ochem nomenclature is right out the window
use it or lose it, i suppose. although, it's likely it would come back to you quickly if you tried to study it again.
Don't try to memorize the information. You have to strive to master, not know. If you understand it, than it will always be with you.
My professor told me that it is okay to forget stuff. That is why you take good notes. You just need to understand the topic well enough such that when you revisit those notes, the information will come back faster.
@DooBick yeah, I'm gonna go ahead and guarantee you that no matter how well you *think* you understand a very difficult mathematical concept, you'll never be able to recall it a few years without having seen it. Not everything is basic mathematics. You can't expect the guy who put his life into fluid mechanics to recall the finer details of topology he learned in his undergrad.
what's the portal gun formula?
Terry Foldy Holes Ohhh that on is easy
I am a Year 2 Physics Student and I have to say that this is a very good explanation for our situation. For other subjects, you answer something for a question. For Physics, they ask you something, you literally spit out a whole essay of equations and explanations for one question.

Raise your hand if you are a Physics student.
I'm studying for one of our theoretical physics exams at the moment and i just found your channel. I must say it is very motivational to see other people, who have been were i am now, that have succeeded in what I'm trying to do ^^.

I'm glad I don't have to take tests, since I'm doing this purely out of the personal interest.
Those QM questions are from Griffiths Quantum Mechancis, a really nice textbook that you can find online in a free pdf.
Elias Mårtenson good for you my dude. What's your real name btw?
For how long have you been studying on your own and what was your background knowledge?
take a look at the qm book by Zettili. the examples are great
You really can't continue learn physics (especially quantum physics) without being able to do this test. If you can comfortably do this test, you should be fine getting into modern formulations of physics. Otherwise, you'll be pretty lost for a while.
I feel like if you actually paid attention in this course this exam would be super easy
aakksshhaayy
I think your comment applies to every university exam ever set. As a now retired lecturer, my experience was that the students who attended the course were the ones who aced the exams.

Joshua Saffy ooof that's brutal! Don't think I ever got hit with an atwoods that annoying!
1. Lagrangian formalism.
2. Perturbation theory.
3. Quantum commutators and virial theorem.
4. Special relativity and metric.
I liked this video, I would fail this test but it's good to know what to expect.
i'm sure you wouldn't fail if you had been in the class and done the work :)
ZorroVulpes #REKT
You sure are one of my most favorite physicists out there! I am only in 9th grade and I want to become a physicist because of your videos!
Oh hell no. I'm dumb AF and can't do this. Sticking to programming and data analysis. It's still hard but doable for me. Good job to those smarter than me. You're awesome if you can do this stuff. 👍
I don't think physicists are smarter than anybody else, we just have different strengths
I agree, it's just about how people see the world and how they want to work on it. Mindset is everything, and courage of course. passion comes along (I hope).
What does smartness mean anyway?
Hey, any book suggestions for an aspiring computer scientist (with a great interest in artificial neural networks/AI)? Plus, books for an aspiring physicist??? And complementary math books????
Tibees That’s where you’re wrong kiddo. On nearly every measure of “smartness”, physicists come out on top. That being said, I’m an Econ major lol
I am nothing.
that statement is false
you cannot be nothing
or can you...?
At least you're not everything.
Proud Autitian
U reminded me of vsauce😂😂
I'm feeling the same.
Davis Davis You must prove it theoretically. Otherwise, it is not a valid statement Sir.
"...Griffiths, a really good quantum mechanics textbook" lol good one
Wow you sure watch a lot of Rick and Morty
Yes, quite a lot of Richard and Mortimer
lol
dick and morton
+IIceWeasellzz doc and marty lol
Brick and Mortar is my favorite show

You should show them the EM exam from Jackson. Lol

at this level, only the strong survive, my hat is off to you, young lady, you have done well to even be involved in this.
You seem to have the perfect demeanour and attitude towards learning, for physics, wish you well, thanks for posting :-)
Soooo much simpler than I was expecting. I expected huge walls of text with 43-letter words. This is very encouraging.
Not joking, I feel warm and calm and happy knowing that I will never have to do that.
How many Rick and Morty episodes would it normally take to be able to do this exam?
about 2 seasons from experience

Griffith is such a great writer, every other Physics book I’ve used after his just feels incomplete and unclear.
Why is it so much fun to see how few you know about a certain topic
Love your Schrödinger's cat poster.
Me: "I'm Ready :)"
Sees Exam Paper.
Me: "I wasn't ready O_O"
I love it Universe,Life,Matter,Energy and infinity,greetings from México.thanks very much for you video.
I flunked the only physics class I've ever taken, and it was freshman year of highschool. I clicked on this to see how hard it is but ended up watching a foreign language video.
Seriously your voice is very calming and it soothes me.
I'm a comp science major and I'm glad I didn't choose physics, this looks hard
I remember doing Lagrangian Mechanics when I studied Physics at uni. Deriving the Lagrangian, L, would be relatively easy. Turning the handle on the calculus to actually find the differential equations takes time and is prone to mistakes.
that looks pretty smooth and straightforward

I have watched some of your videos the past few days. I feel they are helping me to get a better perspective when choosing what to study next fall and I'm certain my choice will feel a lot more safe thanks to you. So thank you for doing this.
I like how they put just one empty line after each part of the question like it's supposed to be enough :D
I used this text book when I took quantum mechanics. One of my favorite text books for sure!
Answering these physics questions make you appear AS IF you had great powers, because you do; Mind over physics.
I am hoping to someday acquire this power as well.
Thank you.
Dude... chill.
These questions are worded like my IB exams
I have absolutely no clue what you are describing, but your presentation is utterly charming and enjoyable.
Ah yea, the double perturbation chaos electron potential expectation influencer. Yea, I totally get it.
Wonderful videos, Tibees. Thanks so much for sharing.
I think that perturbation theory is probably one of the harder potential barrier QM problems that can be asked for although once you understand delta-function type potentials the problem is straightforward

Watching this video makes me want to go back to university (to study physics)
Recalling all the sleepless nights.. I feel instantly tired seeing that exam lol
3:20 my eyes got drawn towards the equation in the middle and then my brain started melting. I'm glad we have smart people that can understand these kind of things and invent stuff for me to use.
This is the reason why I’m retaking precal. I want to the strongest I can possibly over the years.
2:35 “Explain the signficance of Noether’s Theorem” *cuts away immediately*
Wow, this was really helpful and finalizing my decision to major physics. I was nervous at first, but it doesn’t feel out of reach for me to learn.
Need to see more exam papers thank you.
I have my theoretical electrodynamics and special relativity exam tomorrow :"') At least the first task on your exam looks familiar^^ You and your Videos are awesome!!! First thing I 'm going to do after the exam: To watch an other Video :D
I majored in physics and I loved it. But there were three topics I couldn't understand for the life of me. Not because they weren't interesting but just because they were difficult or over cumbersome. Maxwell's equations in their tensor form, scattering theory for quantum mechanics, and all of thermal physics
I’m so glad I chose engineering 🙈 this sure was interesting though, I guess I’ll binge watch your channel now
The first problem is analogous to a toroidal form. Nice quiz I am going to take mine at two weeks. Regards!
University exams have a definite pattern and few favorite topics. They ask those topics almost every semester . You do those and you can crack any university exam easily.
I've been out of school for 6 years and glad to know, I'd still feel pretty comfortable with all of these questions except that part c in question 3. I don't recall that theorem at all.
Thank you! This was exactly what I was looking for!
I'm a 12th grader taking calculus & vectors at the moment and this stuff seems pretty interesting
That actually looks kind of fun. I wish I had learned enough already to know where to begin with any of those. I have only a guess of an answer for describing the properties of a chaotic system. And that is just the result of reading some things on chaos theory in general. I cant wait to go back to school but at the same time I'm absolutely petrified. Thanks for sharing. It's always helpful to just be able to take a look at the scale of what might be expected from me at some point. I'd like to be as prepared as possible. Now I just need to figure out how to pay for it lol.
Its not that bad if you're actively learning the material. I got my degree last year and I probably couldn't do most of this now.
There's a really slick way to do part a on #3, I'll try to find it and post it
A few years ago, I thought why did I study physics?!!! But now I am happy. You learn math, programming, experiment design, quantum mechanics, chemistry, and a lot more. You can work and change your field in any direction. From applying deep learning algorithms in neural imaging data analysis to building quantum computers, a background in physics will help you.
I don't like it that most people look at this and are scared or give up because it seems to be too hard. Yes, I can tell that it really is hard and physics is no walk in the park. But there is no way to judge this by a simple exam paper. This one is for students who had their lectures and are prepared for questions like these. It would be bad if everybody could solve it just by reading it. It's the same thing as you see an exam paper in French for the first time. No way you can solve it, but that's mostly because you can't speak French. So to motivate every wannabe physicists: Don't give up. You learn this stuff, you learn this language called mathematics. It's still hard, but you can do it.
I hope to see an exam like this soonly. But before, there is lots of study and research to do to enter at a university. But really like the physics, the way it explains our surroundings beyond an exam. Though, it´s a great challenge.
I don't know how I got to this channel, but that looks bonkers. Granted I haven't done physics since High school, I had a mini seizure when she said double pendulum......I think I'll name my puppy lagrangian. Sounds catchy
Nothing is difficult , if you are driven be passion and a will to lead.
These are basic fundamentals of learning the workings of Universe .
It looks a lot easier than I would have thought it would be.
From a video on greys to a psychics exam in my feed ,not even remotely similar but just as interesting
Hello from Moscow Institute of Physics and Technologies.
At university we have a necessarily 5 courses of general physics (Mechanics, thermodynamics, electrodynamics, optics, quantum physics). All exam have a test with difficult tasks and oral answer. At the 3th year we pass the state qualification exam of 5 courses. At second and third year we study Teoretical Mechanics, field theory, quantum mechanics.
#3 is part of my Quantum Mechanics homework this week. Freaky
I remember that at age 14 or so I was proud of the fact that I never bothered to do the homework examples but remembered the proofs at exam time. I had to go back to the proof to create a method to solve the questions, rather than have learned processes at my disposal. Sadly that means that today at 67 I have none of those learned processes at my disposal. Don't rely on your youthful insights, do the brain "muscle training" and get that stuff so it's built in early on!. The simple parallel is learning the times tables.
I have no idea why I thought this would end up being a joke. On the other hand, I love that this video exists, and wish TH-cam had been around for things like this when I was an undergrad so I could have had a better idea how to choose an emphasis early on.
Subscribed for your channel very informative, thanks for existing on TH-cam.
i am a physics lover,physics is my life i am also a JEE asspirent
