Spin in quantum mechanics

[@oakleymc9300]

I rate this video a solid 3/3.

[@nidhishsharma9471]

lol

[@ifrazali3052]

Haha

Most of the descriptions of spin on youtube are either too vague or full of technicalities and lacking an intuitive approach, but this one really seems to achieve the best of both worlds! Great job!

[@lineakristensen1821]

Wtf was unexpected 😂 I often do that in my QM notes.

[@nunoteixeira2129]

brant they should pay you the triple for making this videos, awesome work, thanks a lot!

[@Dekoherence-ii8pw]

5:20 Maybe the correct approach is to say: It's NOT a point particle. If you do a measurement that collapses the wave function, then its position collapses to a point. But the rest of the time, it's a spread out thing. How does quantum field theory describe the electron? NOT as a point particle, right? But as a spread-out disturbance in a field, right? So maybe SPIN is some kind of phenomenon in what the electron field is doing.

Thank you SOOO much for this explanation, too many people online were describing it so vaguely, you just gave a clear picture in finger quotes Thank you

[@guilhermelimberg5326]

thank you for your videos, they have been helping me trough my quantum mechanics course at university. (:

[@sithsmasher7685]

I've heard that an electron must complete 2 full angular revolutions before it is back to its original state. Is this why it has spin 1/2? And if so, how does that compare to a spin of 3/2 or 2, 3 etc. ?

[@josephvarghese2000]

this is quite interesting

[@manishsingh-vk8if]

That's why they are called spinors.

[@wearytrader535]

I see, the wt operator also acts on f!

[@ifrazali3052]

Haha

[@md.sharifulislamsharif3196]

Thanks a lot for this helpful video on angular momentum.I'm studying in physics at jagannath university,Bangladesh.

[@lauraciavarella6351]

Super video ,great explanation!!!

[@hauaywkos6638]

Thanks. It was very much helpful.

[@MisterTutor2010]

@4:08 Spin WTF LOL

[@photon7777777]

Great video! Are you really writing wtf in a Physics video at 5:49 - I had to look twice at that :)

[@david52875]

Jack Adams omega tau phi?

[@se-yeonheo8394]

love this videos

[@andrehucek8919]

isnt "L" the azimuthal quantum number ?

[@ifrazali3052]

That's small l Capital stands for Angular momentum operator

[@cubedude76]

does someone really understand classical physics if they don't understand what position and velocity are but they know they are just properties that particles have?

[@camdenfitzgerald2557]

you wouldn't understand classical physics but you could probably do the math for some of the things in classical physics if you took a calculus course.

[@manavmanavchhuneja1]

Marry me Brant

[@stipepavic843]

hahaha thx alot ,great lectures , epic wtf :D

[@FlintPet]

did anyone understand the spin =wtf thing

[@ifrazali3052]

Of course That was a joke

[@paulboro5278]

wtf?haha
