What replaces wave analytic continuity in the Matrix Mechanics picture?
In the schrodinger wave formulation of quantum mechanics, analytic continuity of the wave function plays an important part. What replaces analytic continuity when one switches to the Matrix formulation of…

Poincare Recurrence Theorem – Mathematical
Poincaré Recurrence Theorem The Poincaré Recurrence Theorem is a foundational result in dynamical systems and ergodic theory, which asserts that a system in a finite phase space will, after sufficient…
Trajectories don’t exist
One of Heisenberg's greatest triumphs was simply eliminating the whole thought process around classical electron trajectories. He claimed that there are only observable quantities - and these quantities can be…
