| Nov 29, 2020 at 19:59 | comment | added | JEB | it would help if you numbered all the equations, since you are asking about relations between the equations. | |
| Nov 29, 2020 at 17:29 | comment | added | Noumeno | @CosmasZachos Your comments inspired me to post another related question regarding my example, it would be wonderful if you could take a look at it when I will post it. | |
| Nov 29, 2020 at 17:00 | comment | added | Noumeno | @CosmasZachos For example: if I have an exercise that gives me the spinor in terms of the second definition, giving me $\psi_{1/2},\psi_{-1/2}$, and then asks me to find the possible results of a measurement of $L_z,L^2$ then to find the answer I have to expand the spinor/wavefunction using $Y(\theta, \phi)$, otherwise how could I solve an exercise like the one I am mentioning? | |

| Nov 29, 2020 at 16:50 | comment | added | Noumeno | @CosmasZachos Yes he did, why? Is it incorrect? | |
