idk man, i'm learning this stuff at university rn. I think this guy just chose a very convoluted way of reaching a solution. This stuff is definitely learnable. Just find a good textbook.
I remember doing this for physical chemistry and it's as long as I remember. This is just for one hydrogen atom though, the first and "lightest" element... It's different when you consider that hydrogen is usually a molecule of 2 atoms, which makes it more complicated with 2 nuclei such that you have to use the born-oppenheimer approximation to make the math a bit easier.
because when u doing the differential equation, its better to find a way to write a expression that is continuous. the variables "r", etc are all quantized, therefore is really hard to find a solution for de D.E. if you write it in therms of continuous variables u can guess solutions easier. usually exponential: because in differential equations we want aways to deal with continuity and so on...
I think he was forcing for normalization for x or rho to infinity. Because every solution in quantum mechanics (at least as far as I know) has to have a solution even into infinity. (Think of a free particle in an infinite space. If you solve for the whole space into infinity it has to be somewhere thus yield a solution)
@@asdfasdfasdf383 Yeah quantum mechanics can be wierd sometimes but it's a beautiful ride. If my explanation was a bit off you can search for normalization condition.
consciousness is an oscillation (or a spin or angular momentum, if you will). It is fundamental and measured in h bar. It cannot be factored. It is eternal. And true physicists call it action. Peace.
@@athul_c1375 So are you saying that things can decide which path they should take (from Lagrangian Mechanics)? And that the universe is lazy (again from Lagrangian Mechanics)? That's what the math says if you take it literally. These totally absurd predictions by physics pretty much tells us that it is just a model of reality but not reality itself Another reason why physics cannot be reality itself is because it is literally a set of approximations. Even if we get to the theory of everything, there would still be a very large chunk of physics where approximations rule. And math cannot be a model of reality. Math is about abstract patterns and stuff, not real things. Let me clear this up. A model is something that is useful in making predictions in reality. Math can be used in models, but math itself isn't. For example, take number theory. It is a branch of math that is about integers and their structure, but idk if that can be useful in modeling any physical phenomena. Plus I have already said what the "purest" of math is all about: abstract stuff and patterns.

A class in mathematical Physics is needed. It's not as complicated as it looks when you know the prerequisite math.
When you thought you can learn QM from TH-cam at your leisure, this video made you think again.

his board handwriting is actually really good, it's eyecandy for any mathematics/physics students who loves the symbols lol
That is exactly why I prefer his lectures, so prestine!

What is the point in cleaning up the units as made about 4:34 and in other classes?

Why U=p"(l+1) ? Please tell me. Thanks.
it's explained in more detail 2 lectures prior to this one

@@philipp8276 which minute?, can't find it
How the final equation about w comes?
u=ro^(l+1)*exp(-ro)*w(ro)
Calculate d^u/d(ro)^2 and substitute there.
At some point, we're assuming that x goes to infinity - But here did this assumption come from?

What about factoring in consciousness. Intent. Yes we can calculate it. But what about the observer understanding that the atom is in fact conscious.

Great video Tell inks are also required
Nope did not understand
Congratulations no one did
What is l(l+1)?
I believe it's from legendre transformation
It's the eigenvalue of the L² operator, which is what the whole angular dependence operator turned out to be (lectures 20 & 21)
I guess, it is the squared version of the angular momentum of the electron around its nucleus
how can we just make up an equation for r.. and then also make it look completely random.. ^^

I struggled in HS in algebra and I watch these to make me feel dumb and depressed 🙃
physics is wrong thing to get depressed about. trust....

It was asked in iit 2017
that's why iit suck
Great content 👍👍
