Angular momentum eigenfunctions

[@nUrnxvmhTEuU]

To make notation in this derivation less confusing, one can write unit vectors as e⃗ᵣ , e⃗ᵩ , e⃗_θ. It is quite standard to use the notation e⃗ⱼ for basis vectors, so it will save a lot of cognitive work. (Sorry for the ugly subscript in “e⃗_θ” but sadly there is no subscript theta in unicode.)

At 9:10, there is an error in expression. It sdgould be cos(phi) j-hat & not cos(theta) j-hat

Congratulations this channel is very good

Great video Doc. Thanks

[@bradwang3648]

thank you!!! finally understand it!

[@nunoteixeira2129]

Just wondering, are you following Gasiorowicz?

[@AdamKlingenberger]

+Nuno Teixeira He is following Introduction to Quantum Mechanics by David Griffiths

Can we use Lz given in spherical coordinates formula to find eigen value of Lz ..please reply

[@astrologysign1409]

Did u find it plzzz help

Did u find it plzzz help

[@ifrazali3052]

I don't see a reason why not

"L as E is a conserved quantity in quantum and classical mechanics so it is interesting..." wow, conserved quantity are key to solve the dynamics of physics ... they are not just interesting they play major meaning in physics ... we use them to "label/identify" physical systems ...

[@chiranjali8850]

sir how can we calculate eigen values lx^2 + ly^2 operator

[@ramansb1008]

thank you

[@safaa0thman134]

Thanks

[@physicschemistry6806]

wow!!!

[@fornasm]

Prof Carlson always good in concerning about maths, but I would have preferred more attention to Physics and avoid sentences as: " it would be nice to know how our L acts on this general psy(r, theta...) ..." Nice!? ... It seems we are doing all these calculations because it is "nice" ... isn't this Physics?! I thought we do all this to gain better understanding of Physics (geometry, what we experience physically ...). One of the major physical problem is considered here is atomic physics that has spherical symmetry ... this is major reason we are considering L and spherical coordinates etc

Maaaaaaaany thanks

are you left handed?

quantum physicist*** Nice video though :)
