The Hidden Variables interpretation brings quantum physics back into the same logical realm as classical physics: everything is deterministic and predictable. If we knew the position of the electron and the value of the wave, we could predict everything. But it’s not really as simple as this. As it happens, we cannot ever know the wave, because we never see it: we only see the electron.45 Hence the behavior of the electron is determined by variables (the wave) that for us remain hidden. The variables are hidden in principle: we can never determine them. This is how the theory gets the name
