It is the REAL meaning of inflection ( not watched as yet…. But looks promising )

Bro . Although this is a channel for quantum maths but pls do cover such micro but nuanced and important topics of math as well . Like topics of calculus - I think concept of limits and meaning of it's formulas is part of an abstract section of mathematics (at earlier levels of maths ofcourse. otherwise higher theoretical maths is nothing but abstract). Take up other such concepts from calculus , complex numbers like topics . Great video ofcourse. Subscribed ur channel . Cheers. 🎉🎉

I still find it hard to twist my mind around vector space is just describing patern because in my mind I see vector as arrows. It would be great if you could show me an example of vector space made by a different set of object! Very please!

well this is... beyond me. At least the intro gave me a different understanding of the first derivative. Guess I'll be back in a few years once I have a handle on that taylor bullshit

0:45 ... 2:05 ... 2:30 ..."INTUITIVE"... Are you sure?... Why do you spend all your time... EXPLAINING... it... REASONING... it?... INTUITIVE... has become a PEST!... I GAVE UP!...

I love when the math I've been srruggling with has unexpected ties with the science I'm getting a foothold in

How would the Momentum based SE Look If WE Had a 1/x Potential?

The best quantum theory series!

This is an awesome video! Thanks for making these! However, there is one fundamental part that I don't seem to understand, and I was hoping somebody could help me: That is the relation to the ball for 2D: We look at the 2nd derivative at x0, with f_around calculated based on x0 minus dx and x0 plus dx. That all makes sense to me, but that is not necessarily a circle centered on x0 (as pr the illustration at time 4:35). So how does the circle become a part of this? Grateful for any help.

Nice coverage of topic. Thanks. Subscribed. Cheers

at the end bro planted us a bug in the head and left the chat

As an Economist my only thought!! To set a Necessary condition for Maximum or minimum

10:13 - There is something I havent understood for a long time here. psi is in position representation, right? Here you just turn the position wave function into a "continuous vector". However psi can also be expressed in terms of momentum, then it would be |psi> = integral(c(p)*|p>) right? but that means that |psi> = integral(psi(x)*|x>) = integral(c(p)*|p>) which I am pretty sure is not true. Do those psi-s then represent a different hilbert space element, and it is just poor notation that we use the same letters for them? Can someone please explain?

square of dx is (dx)^2 or dx^2 please clarify

These videos are just so well made and memorable, I love it

Bae: Come over Me: can't- I'm an arbitrary vector in an N-dimensional Hilbert space Bae: I'm a linear self-adjoint operator A on If, thus my eigenvectors form a basis meaning that every vector in can be expressed uniquely as a linear combination of my cigenvectors: ln) Aln) =AyIn). Me: :-) -) )

O my Allah,,,what an explanation! Thank you brother for your hard work. the people who represents physics in a meaningful way, i respect. May Allah grant you.

Smallest to small bigest to biger

Thank you a lot

Great Video! Appreciate the effort you take in explaining all these things to enthusiasts! Must have been a lot of effort in the editing as well, Could you please tell me which tool/platform do you use to edit videos like these with equations and numbers flowing around the screen? I would love to create something similar very soon!

Is there similar channel devoted to GTR?

Ancient greeks have used intuition and reasons If you know space ecuation, the first der is speed and second is acceleration. So second der is the dynamic of the function. Your demionstration is excelent model. Cong.

Misleading title: the video does not actually define bra and ket notation like the title implies.

12:58 can someone explain how the chain rule is applied here?

Loved the video! You are really an amazing presenter. One thing that I *will* bite the bullet for is calling Laplacian *the real* second derivative in 3 dimensions. The full second derivative is really a bilinear form, also represented as the 3x3 matrix (hessian) of all possible second order partial derivatives, which the laplacian is just the trace of. There are other second order differential operators that you could get from it.

Great initiative. Very niche approach .thank you so much

Tells concave up or down.

technically, there is an error on 1:07 in taylor series formula

What would happen if the time evolution operator were NOT unitary? 0:04

5:30 "now I'm gonna divide by dx^2" bruh.

Watching this as if I didn't get a 52 on my Series and sequences exam.

i am starting my first semester at university at UCSC, and am looking forward to my physics major. thanks for uploading this playlist for me to look forward to viewing the first time, not knowing much of anything, so i can come back in the future and laugh at how much i didnt know.

Imagine waisting time to study these simplified QM mathematical course, i'd better bay some actual textbooks and learn it properly. I was looking for some compitent popular explanation by words, I believe it is pretty possible, not for nonsense like this

Wow. I'm not so good with math yet this is insightful. Kudos

This is such a great video, can't believe I've never looked at the second derivative like this. I'll definitely go and watch your series on quantum!

진짜 영상 말도 안되게 잘 만드셨네요!!! wow

6:00 Iff you can take the derivative from both sides, that isn't always possible but often holds in physics.

I think that Feynmann was talking about the Cauchy integral theorem. He stated he didn't need to know the center value just the value on the exterior ball.. that is exactly the Cauchy integral theorem -- you average the surface of the ball and you have the center value

"nature seems to choose the simplest expressions" *watch in standard model"

Well done. 15’ of great physics

Good❤❤❤❤

This is an great video. I have a BSc in Mathematics, and I never knew about this

In fact, all differential quotients of a function are defined by a kind of "curvature". Even the first one shows that the function starts to deviate from the straight line at the given point. The further derivatives give an even more accurate picture of the behavior of the function. Why is the 2nd derivative THE "curvature"? Maybe because the others are negligible from this point of view?

Uhhh concavity

0:14 people who know the π joke 👇

it describes acceleration

Please make a same for General Relativity

mate youve killed this video! Such a complex idea explained so concisely

we could consider the brain as a quantum converter following Immanuel Kant's perspective idea
