Mathematically, quantum mechanics can be regarded as a non-classical probability calculus resting upon a non-classical propositional logic. More specifically, in quantum mechanics each probability-bearing proposition of the form “the value of physical quantity \(A\) lies in the range \(B\)” is represented by a projection operator on a Hilbert …May 12, 2015 · Leonard Susskind is the Felix Bloch Professor in Theoretical Physics at Stanford University.

Nov 29, 2000 · Quantum mechanics is, at least at first glance and at least in part, a mathematical machine for predicting the behaviors of microscopic particles — or, at least, of the measuring instruments we use to explore those behaviors — and in that capacity, it is spectacularly successful: in terms of power and precision, head and shoulders above any theory we have ever had. These examples show that commutators are not specific of quantum mechanics but can be found in everyday life. We now want an example for QM operators. The most famous commutation relationship is between the position and momentum operators. Consider first the 1D case. We want to know what is \(\left[\hat{x}, \hat{p}_{x}\right] \) (I’ll omit ...
