Time-Evolution in Quantum Mechanics is a “Flow” in the (Abstract) Space of Automorphisms of the Algebra of Observables

In quantum mechanics, time is not a geometrical flow. Time-evolution is characterized as a transformation that preserves the algebraic relations between physical observables. If at a time t = 0 an observable – say the angular momentum L(0) – is defined as a certain combination (product and sum) of some other observables – for instance positions X(0), Y (0) and momenta PX (0), PY (0), that is to say… 325 more words

Arithmetic Operations

There are only 4 binary operations which we call “arithmetic operations”. These are:

  • Addition (+)
  • Subtractions (-)
  • Multiplication (×)
  • Division (÷)

Reading this fact, an obvious question is: 398 more words
