Re: Some questions about QM

*We know that some observables (like momentum and position, and energy and time) are non commuting, therefore any theory that attempts to describe that behavior is going to need to have non commuting mathematical entities in it. And if you're going to explain the quantum interference effects that o

Some questions about QM

1) What necessitates the use of complex numbers (whereas in GR only real numbers are used)? 2) What necessitates the postulate that some, but presumably not all operators are non commuting? 3) With respect to 2), why is the non commuting difference i*h (or i*hbar)? TY, AG -- You received this
