Hi Dick,

I don't think there is much that can be said as to the effect of changing Planck's constant unless it is accompanied by a change in proportion with other constants. That is, we can set Planck's constant to one (i.e., h=1) for example, and this works just fine in the equations. The trouble would result if Planck's constant was 1 and pi became 1 (to use an extreme example). In that case, the equations change quite enormously. The value for Planck's constant is merely a measurement based on some values being set at one (e.g., 1 joule). If we set Planck's constant at 1, then one of the implications is that some other constants would change (but not pi, it remains the same as we all know at least in the decimal format).

Warm regards, Harv
