quantum mechanics - Why does the wave description say that probability oscillates, while the phase interpretation says constant amplitude?


The wave description of a particle illustrates an oscillating probability of the particle being found in any point in space.


When a particle travels, it carries along with it a phase that oscillates in the complex plane. When the particle travels, the amplitude never changes although the phase does, which doesn't matter. The only property that matters is the amplitude.



Why does the wave description say that probability oscillates and the phase interpretation says constant amplitude? What am I missing?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
