May 28	comment	Deriving the Angular Momentum Commutator Relations by using $\epsilon_{ijk}$ Identities how exactly would i argue the cyclic permuation?
May 28	comment	Deriving the Angular Momentum Commutator Relations by using $\epsilon_{ijk}$ Identities I tried this out and I think the identity you give is wrong. If we apply [A,BC] = B[A,C] + [A,B]C to [AB,CD], we get the RHS of your first centred equation.

May 28	comment	Quantum Mechanics, Uncertainty Principle— help understanding notes so if the uncertainty with respect to $\hat O_A$ is 0, then the uncertainty with respect to $\hat O_B$ is undefined?

May 26	comment	Deriving the Angular Momentum Commutator Relations by using $\epsilon_{ijk}$ Identities This is exactly what I was after, thank you. My problem was that I didn't use the commutator relations, I think I got a 3 i'd monster somewhere too.

May 26	comment	Deriving the Angular Momentum Commutator Relations by using $\epsilon_{ijk}$ Identities @user10001. I prefer to do the more general version. For your way I would then have to make an argument for cyclic permutations, which isn't what I wanted to do.

Apr 24	accepted	Is it physically meaningful to talk about the 'total temperature' of an object?
Apr 24	comment	Is it physically meaningful to talk about the 'total temperature' of an object? Is there no 'conservation of temperature' which means that the two objects should have the same total temperature? Can I calculate the internal energy of the objects and then get a conservation statement?
Apr 24	comment	Is it physically meaningful to talk about the 'total temperature' of an object? ah, so is it not meaningful to talk about the temperature at some point? Rather, we should talk about the temperature in some region?
