This is so great!

Very nice graphics man, keep up the good work! Your channel is imensly helpful for STEM studensts

[@fufaev-alexander]

thank you very much!

[@sathanimadhu9221]

could you pls explain difference between eigen state,eigen function, eigen vector.

[@fufaev-alexander]

yes, I will do it

[@umbraemilitos]

I think algebraically they are quite similar. The main difference I see is the physical or geometric interpretation, and whether it is discrete or continuous like with a Hilbert space, and if there is some notion of Fourier pairs and commutivity relations.

Excuse me, I have a question at 1:30: why could we swap? And it obviously is not scalar, they are two matrixes, right?

[@learngermanwithvanessa]

We can swap because two scalar functions are commutative.

[@SplendidKunoichi]

we can swap because no, they are not matrices. Psi might technically be defined as a column vector in a hilbert space but understood to just be a complex-valued function. H is an operator on Psi that won't change this, so it would actually be a row vector times a column vector which we know is the scalar product

[@An_art_appreciator]

Omg I've the same question too. Do you have any reason why it is?

[@sathanimadhu9221]

nice explanation 👍

Stern Gerlach experiment and electron spin. Especially the prove that electron is spin half particle. I'm pretty much confused as to what is half spin actually. A video is requested.

[@fufaev-alexander]

Thanks for the video suggestions! I will mention them in the next poll! If you regularly visit my channel and like my videos, I would be happy about 1 x coffee ☕ per month: kzbin.infojoin

Nice one 👍👍👍

thank you 😊

I hate that good content nowadays is so much under appreciated ...all people want is intrigue there 5 second attention span ..they just say they all wanna learn something but only on surface level..dude i know i shouldn't say this or have the right to even remotely say this but i think u should quit making these cause it,ll be huge waste of your time and motivation if no one appreciates your work and should focus only on what you like... again i am extremely sorry but this is all coming from a good heart...or ...you can continue to make these phenomenal conceptual videos, if you like making them ...who am I to be in your way...i .am just a rando..♥️♥️♥️

[@AhmedZaki-lh1zw]

Thank very match

[@fufaev-alexander]

Thank you too

What do I need to understand this type of mathematics a new brain?

[@matusmoro955]

I think the way to go about it is to expose yourself to gradually more difficult and abstract physics subjects, perhaps starting with classical newtonian mechanics, then move on to electromagnetism, then perhaps thermodynamics, lagrangian and hamiltonian mechanics and then quantum mechanics. Just an example. This was the rough order of subjects during my undergraduate degree.
