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.
Ardit Mehmeti , oh my goodness! That’s totally me as well because I used to be incredibly quick with mental maths and my mental maths isn’t as good since my degree and I never figured out why... could it be because ‘you either use it or lose it’ when it comes to mental maths?

Lol that's how I found out I should be an engineer. I need the practical application ( or at least the context of when a formula should be applied) for the concept to click. God bless my precalc teacher.
In my math classes, "practical applications" were actually "we can use these abstract math results to prove other cool abstract results in a different branch". Like solvable groups (or w.e they are named in english) are used "practically" to prove Galois fancy stuff

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

"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.
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.
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.
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.
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
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 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
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
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.
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.
Wow I’ve never watched a video right after it was uploaded... I’m so buried in Class Mech homework I’m literally watching physics videos as soon as I wake up to remind myself it’s still fun. Thanks for the joke videos!!
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!
"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?
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*
Clearly a smart dude... makes interesting and mathy videos... willing to self-deprecate... well done, mate. Keep on with bringing positive vibes to RUclips.
Seeing this video made me suddenly understand the hatred math students have for physicists. I can now live a more happy, rigourous life. Tbf though, not conflating GL(n) groups with their matrix rep is like having a hat and saying "This is a representation of a hat. The hat I bought online was an online hat, not the same thing."
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.

“Ok you guys want to see a fight” had me crying
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.
I love that smile when the lecturer starts waving his hands: such deep relaxation. Life can be so simple when you just cut to the chase.
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.
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.
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.

"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.
The perfect collaboration doesn't ex...
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
As a literature student I know this was a great story

Flammable maths: how do you know that?

the waving the hands thing is so on point!
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...
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.

As a postgrad student in physics, this is accurate af and amazing LOL!!!
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*

Seeing this video made me suddenly understand the hatred math students have for physicists. I can now live a more happy, rigourous life.
Tbf though, not conflating GL(n) groups with their matrix rep is like having a hat and saying "This is a representation of a hat. The hat I bought online was an online hat, not the same thing."
I'm doing a physics degree and I can confirm this is 100% accurate 😂
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.
