They’re not just for glasses any more.

It’s moving from one space to another. Moving from one state to another.

Most of the time we spend our time in the same mental place not moving far. Brownian motion subtly jostles us around and give us the mirage of change even if it’s barely happening at all.

Real change happens when you jump from one position to another. Like the quantum states of electrons — they move from one state to another without traversing the areas in the middle. Or on a larger (if still tiny) the tunneling of particles based on the uncertainty of their wave function. That is change.

But it’s not just you that changes. The place from which you left and the place you arrived at changed as well. The electron that tunneled across a barrier gave it’s charge to the other side.

A new equilibrium must be reached all around: the electron, before and after.
