Question for Marianne:

Is it possible that h/2 is the fundamental quantum size? If we define a new Planck's constant (call it hs) such that hs = h/2, and plug that into the Schroedinger Equation, does that change the usefulness of the equation (or add any other complications to any aspect of physical laws or quantum mechanics)?

I have a reason for asking that, which we can discuss if your answer is no.
