Flammable Maths man look it’s the real Andrew Dotson. Are you going to use the trope where they just assume/approximate/do sth weird and us math students get Vietnam flashbacks?
When I was a physics undergrad, I was in differential equations class.There were about 15 students. The professor was a mathematics professor who taught way above the standard level and way beyond the textbook. He rarely ever turned to look at the class. There were about 5 physics majors, 9 engineers, and one math major who sat in the front row and always appeared to be asleep with his head on the desk. The professor would start lecturing and lose about one student every 2 minutes until we were all looking at each other shrugging. Then professor would ask a question. Not turn around, just ask. No one would respond and he would repeat the question. Then say “anyone? Anyone?” in the much parodied style of professors. This would go on for an uncomfortably long period of time, then the math kid up front would suddenly sit bolt upright, give the correct answer, then lapse down onto the desk, apparently asleep again. I will never forget that class, lol.
My vector calc teacher told us the other day "ahh, i love teaching engineers, yall dont care about these silly proofs so i can just show you cool things to do with these instead"
Actually kind of true. A lot of math lectures, at least on graduate level, is dedicated to enormous proofs that are very often uninteresting technicalities. It is not until research level/seminars that people just say "oh do this and that, and some trickeries here and there".
Math and physics' job is to take every piece of information to understand how the world works. Engineers' is to take that shit and use the useful concepts. We don't have time for demonstration jerkoffs

This is a joke a friend of mine, who studied Physics, told me: _How do you find the volume of a cow?_ _Engineer: Just fill a large enough container with water, put the cow in, and collect the water that falls out. That will tell you the volume._ _Mathematician: Divide the cow up into infinitesimal cubes, and then add up the volume of the cubes._ _Physicist: If the radius of the cow is r..._
Mine says something like "If you use a few substitutions, you get the following... I won't show you the integration steps because this is not a calculus class, you already know how to do it
To be fair i did lebesgue measure and integration while studying L^2 spaces (im a physics undergrand) and theres no way you dont have to evaluate integrals on your own etc.. ofc the video is made like this for entertainment and its okay like that xS
Well not as the video says you don’t really have to know measure theory to do the functional analysis. The small l2 is a Hilbert space, and so is the completion of continuous function R to R on closed interval defined with normal L2 norm. There are lot of ways to construct Hilbert space. In face, space of functions of at most countable nonzero values defined with the dot product as sum (x in R ) f(x)g(x) is also Hilbert

Both of my parents are math professors and I always had a hard time at math until I took physics. I learned that I just have a tendency to accidentally copy numbers incorrectly so I learned to substitute all the numbers for letters, solve for the variable I want to know, and then put the numbers back in to the equation. I thought I was just bad at math until I started doing that and then I got things right for a change, although I still have to be careful with signs.
Dude that was me. I hated math thought I would never pick it up until I started learning algebra. Then it all clicked into place for me. It wasn't until I got into physics that I discovered the beauty of maths.
Im a economics major with IT minor but physics and philosophy have always intrigued me so much. Economic theory and Philosophy were my favorites classes.
"Hand-waving" is a term used to denote making a complex proof really easy by skipping all of the rigorous parts and just intuiting it, which is FAR less prevalent in theoretical mathematics courses than phys.
Umm, Dirac deltas don't really have inner products, do they? They only have duality couplings with continuous functions - if you are GENEROUS!!!, and mostly only duality couplings with smooth functions of compact support. No Hilbert spaces there, my boi! None at all!!!
Let B be a linear span of sin functions. These are continuous and the scalar product can be defined through Riemann integrals. I'm not sure, but I think the metric completion of B will be our desired Hilbert space L2, and the scalar product can be defined through limits of scalar products of sin functions. Also, the sequence space l2 is a Hilbert space as well, and it involves no integration at all.
@@bogdanlevi Ok, You are trying to define L2, but here is the point: Dirac Delta does not belong to L2. You cannot define the integral of the product of Dirac Delta and a L2 function because L2 functions cannot be evaluated in a point.
If G is a locally compact abelian hausdorff group we can equip G with a translation invariant regular measure. With respect to this measure, L^1(G) can be embedded in the space of complex regular borel measures M(G) where the dirac delta function lives.
I'm a math major, and thoroughly enjoyed this video... was sitting in math class the other day and suddenly thought of, "It's easy, you say: assuming the necessary assumptions, let H be a Hilbert space," and had to stop myself from laughing out loud right there. The juxtaposition of that line with the nature of this particular math class -- where you have to check whether you're allowed to assume 1 + 1 = 2 when writing a proof -- is just so good. Awesome video man, thanks for the laughs.
Andrew- Congrats on 100K subscribers! This was a Great collaboration for both you and Flammable Maths. I enjoyed them both immensely. Thanks and keep it going.
Feynman was even cooler than most people think. The only proof one needs is his own books and papers. They are excellent. He was the last to revolutionize quantum mechanics with his path integral method and his diagrams. I admire him greatly
Utter nonsense. All the mathematical methods I needed for my physics classes were lectured in those. It was only in our math classes were we learned why/ when these methods work and the mathematician way to look at it, which often doesn't help to understand the physical problem. Especially the early physics courses require mathematical methods which will only be introduced in later math courses. E.g. distributions and PDEs are heavily used in electromagnetism(first year of physics), which will most likely be taught in a second year math courses.
@@Ryuuuuuk The machinery of distribution and PDEs are , in France, a grad school subject (at least M1, 4 years of uni). There is nothing wrong with not learning the fine machinery tough, you don't need it at all to solve physics problems, and it is sometimes very pedantic to try to teach that to undergrads, but it is always a good idea to be familiar with the tools you use later.
I love throwing Laplace transforms at things until they go away, its my second favorite pass time aside from throwing (1/n) / (1/n) at limits to make all the zeros
My electrostatics professor the other day, in a quiz on Laplace's equation and boundary conditions, claimed that "all PDEs can be solved by separation." It was presented as a "correct" statement in a multiple-choice list, and consequently we were docked for omitting it.
ah yes, brings me back to my college days as an engineering student, going to a physics class to learn how to do something one way, then going to a math class to learn how to do the exact same thing another way, and being told by each respective professor that their way is right. lol, and looking back on it both the physics professors did wave their hands around a lot, but not the TA's. guess they weren't there yet.

3:14 , I can Totally Relate to This, Even Though I'm just a 14 yr old Learning Theoretical & Mathematical Physics, Physicists need to use Hand Expression, I also do it when Doing a Lecture and Uploading it, it basically now, kind of became by your Subconscious Mind, just happens directly when exactly, but, still I don't know Why we basically do it, like what's the reason?!
Lots of stuff is very accurate (*of course* boundary terms always vanish) but in my experience it was always the maths majors who had trouble actually computing integrals (rather than say, showing they converge to something) and needed tables for anything beyond polynomial 😅 whereas we had to learn all the integral reps of generalised laguerre polynomials and bessel functions and so on *shudder*
Man... just to mention that in my university the professor giving Quantum Mechanics I was more mathematically rigorous than most calculus professors I had. It's physics not engineering we a talking about.

I was raised by the math department then groomed by the physics department...

In fairness, when you’re in the real world using math and science to figure out issues you’d normally be able to look up the equation if you forgot it, wether that be via book or internet.
For every hard math class there is a corresponding harder Physics. Problem with Physics is there is a whole series of steps just to make it into a math question
High level math has very little calculations unless it’s within “applied mathematics”. Outside of applied maths, it’s all theoretical or abstract. Pretty much generalizing statements so much that you can’t assume basic properties you thought you could like how a number times 0 is 0. Or even if 1>0. Maths is all about proving those statements until you build up as high as you can. The best part about it, maths can never be wrong because it is based off of full logic and as little assumptions as possibe. You can have a proof be several pages with no concrete “real numbers” involved.
"It seems to me that mathematical rigor is like clothing: in its style it ought to suit the occasion, and it diminishes comfort and restricts freedom of movement if it is either too loose or too tight." --George F. Simmons

My money is on Andrew, although it will be a tough call. Flammy has the power of anime on his side D:
Maybe Flammy can wave his hands while he explains why fighting is a bad idea, and this will confuse and calm the physics student.
I would bet on Andrew, because Flammy talked shit about our boy Feynman. Nobody does that and walks away!

"Could you wave your hands when you lecture? Hmmm, that's nice. I'm learning already." I think this is the most accurate part of this video
Both of my parents are math professors and I always had a hard time at math until I took physics. I learned that I just have a tendency to accidentally copy numbers incorrectly so I learned to substitute all the numbers for letters, solve for the variable I want to know, and then put the numbers back in to the equation. I thought I was just bad at math until I started doing that and then I got things right for a change, although I still have to be careful with signs.
You mean Algebra?
Yo that was a pretty good idea
Dude that was me. I hated math thought I would never pick it up until I started learning algebra.
Then it all clicked into place for me.
It wasn't until I got into physics that I discovered the beauty of maths.
Physicist be like: I’ll start calling your guy “Euler” instead of “Uler” when you start calling my guy “Lord Feynman”.
LMFAO the math department and science department have some serious beef about this at my school
Im a economics major with IT minor but physics and philosophy have always intrigued me so much. Economic theory and Philosophy were my favorites classes.
Wearing a QED shirt and saying Feynman is not cool is a different level of swag. My maths prof waves more than my physic prof.
The term qed is also used in math whenever a proof is done or smt sinilar
Quantum Electrodynamics versus quod erat demonstrandum.
"Hand-waving" is a term used to denote making a complex proof really easy by skipping all of the rigorous parts and just intuiting it, which is FAR less prevalent in theoretical mathematics courses than phys.

Hello there, the oompa loompa of science
"How can you define a Hilbert space without Lebesouebgapge integrals?"
Dirac deltas: >:(
Umm, Dirac deltas don't really have inner products, do they? They only have duality couplings with continuous functions - if you are GENEROUS!!!, and mostly only duality couplings with smooth functions of compact support. No Hilbert spaces there, my boi! None at all!!!
Hearing Lebesgue integrals reminded me of Lebesgue-Stieltjes integrals and i had a little ptsd. Borel sets entered my mind too and I almost yacked.
Let B be a linear span of sin functions. These are continuous and the scalar product can be defined through Riemann integrals.
I'm not sure, but I think the metric completion of B will be our desired Hilbert space L2, and the scalar product can be defined through limits of scalar products of sin functions.
Also, the sequence space l2 is a Hilbert space as well, and it involves no integration at all.
@@bogdanlevi Ok, You are trying to define L2, but here is the point: Dirac Delta does not belong to L2. You cannot define the integral of the product of Dirac Delta and a L2 function because L2 functions cannot be evaluated in a point.
If G is a locally compact abelian hausdorff group we can equip G with a translation invariant regular measure. With respect to this measure, L^1(G) can be embedded in the space of complex regular borel measures M(G) where the dirac delta function lives.
I'm a math major, and thoroughly enjoyed this video... was sitting in math class the other day and suddenly thought of, "It's easy, you say: assuming the necessary assumptions, let H be a Hilbert space," and had to stop myself from laughing out loud right there. The juxtaposition of that line with the nature of this particular math class -- where you have to check whether you're allowed to assume 1 + 1 = 2 when writing a proof -- is just so good. Awesome video man, thanks for the laughs.
Andrew- Congrats on 100K subscribers! This was a Great collaboration for both you and Flammable Maths. I enjoyed them both immensely. Thanks and keep it going.
Thanks neal!
A mathematician: Feynman is not as cool as you might think.
A physicist: So, you have chosen death.
Feynman was even cooler than most people think. The only proof one needs is his own books and papers. They are excellent. He was the last to revolutionize quantum mechanics with his path integral method and his diagrams. I admire him greatly

Just checked Flammable Maths. There is no video about maths students taking a physics class. Is that the joke?
It’s being posted next werk
Maths students don't need physics class but physics students need math class
Utter nonsense. All the mathematical methods I needed for my physics classes were lectured in those. It was only in our math classes were we learned why/ when these methods work and the mathematician way to look at it, which often doesn't help to understand the physical problem.
Especially the early physics courses require mathematical methods which will only be introduced in later math courses.
E.g. distributions and PDEs are heavily used in electromagnetism(first year of physics), which will most likely be taught in a second year math courses.
@@Ryuuuuuk The machinery of distribution and PDEs are , in France, a grad school subject (at least M1, 4 years of uni). There is nothing wrong with not learning the fine machinery tough, you don't need it at all to solve physics problems, and it is sometimes very pedantic to try to teach that to undergrads, but it is always a good idea to be familiar with the tools you use later.

"Feynman, might not be as great as you think"
"Wanna see a fight?!" LMAO I laughed at work, please don't get me in trouble.

You should be a physics professor. Not the professor we deserve, but the professor we need.
Me : fails every thing on basic math and physics.
Me at UA-cam: watching things I have never heard.
Same
ah yes, brings me back to my college days as an engineering student, going to a physics class to learn how to do something one way, then going to a math class to learn how to do the exact same thing another way, and being told by each respective professor that their way is right. lol, and looking back on it both the physics professors did wave their hands around a lot, but not the TA's. guess they weren't there yet.
Mathematicians know that there are 20 ways to do anything. Some are fairly straightforward. Others...
Assuming the necessary assumptions...

Lost at “boundary terms are always zero”
0:29 As an electrical engineering graduate, this made made my day :D
Lots of stuff is very accurate (*of course* boundary terms always vanish) but in my experience it was always the maths majors who had trouble actually computing integrals (rather than say, showing they converge to something) and needed tables for anything beyond polynomial 😅 whereas we had to learn all the integral reps of generalised laguerre polynomials and bessel functions and so on *shudder*
« Boundary terms are always 0 » is exactly what my physics teacher told me when I still studied physics

Assuming the necessary assumptions, assume H is a Hilbert space😂 bwahaha😂🙌
Man... just to mention that in my university the professor giving Quantum Mechanics I was more mathematically rigorous than most calculus professors I had. It's physics not engineering we a talking about.
“Okay, you guys want to see a fight?”😂😂😂‼️
"Boundary terms are always zero." :P . I'm personally past that point though. In GR you got to worry about boundary terms.
"Would you mind waving your hands?"
hahahaha yes! This is why I'm subscribed to this cha... wait. What the what? How am I not subscribed to this channel?
Hahahahaha I love this!! I major in both physics and math and this video officially made me realize where I stand fundamentally... I was raised by the math department then groomed by the physics department... Now I’m starting to understand the depth of my physics professor’s comment whom I wrote and published my first physics papers with... “You are the most mathematically rigorous student I’ve ever had.” I now realize... he was calling me annoying 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
In fairness, when you’re in the real world using math and science to figure out issues you’d normally be able to look up the equation if you forgot it, wether that be via book or internet.
For every hard math class there is a corresponding harder Physics. Problem with Physics is there is a whole series of steps just to make it into a math question
Wait... 1:41 was math? There were no numbers in there at all...
When did English become math?!
High level math has very little calculations unless it’s within “applied mathematics”. Outside of applied maths, it’s all theoretical or abstract. Pretty much generalizing statements so much that you can’t assume basic properties you thought you could like how a number times 0 is 0. Or even if 1>0. Maths is all about proving those statements until you build up as high as you can.
The best part about it, maths can never be wrong because it is based off of full logic and as little assumptions as possibe. You can have a proof be several pages with no concrete “real numbers” involved.
"It seems to me that mathematical rigor is like clothing: in its style it ought to suit the occasion, and it diminishes comfort and restricts freedom of movement if it is either too loose or too tight." --George F. Simmons
Andrew, I hope Jackson isn't treating you too harshly! I know you haven't posted in a while, but as a physics grad myself I totally understand why. I wish you the best of luck with the rest of this semester!
What's even more fun is philosophy students in a Mathematical Logic class taught by a math prof.
Sure, it fulfilled their Logic requirement, but ...
the waving the hands thing is so on point!
