    Also, is spin +1/2 the same as spin up? And is spin -1/2 the same as spin down?

    The first image in the link below is a good reference.

    Thanks,

    The spin energy is equal, however since it is spin in opposite directions one works with the magnetic field to increase the energy of the entire system and one works against it to decrease the energy.
