Thats make more sense to me , Thanks.

Hi, Is it possible for an electron to change the sign of its spin (under some interaction)? i saw that some of the calculations in the Ising model assumes that the electron is changing its spin sign if it reduce the energy of interaction with its neighbors Thanks, Ori.

thanks for the replay. I found a detailed explanation in the Feynman lectures on physics vol 2

Hi, why is the action defined as the integral of the Lagrangian over time? i don't see the meaning of integral on the (kinetic - potential) energy thanks, ori.
