Quantum Mechanics in a nutshell

This takes a little time to get to the point of the main question:

How come we can’t say that a particle is *right there* and that it is moving *that fast* in *that direction* ?

So bear with me. I’m going through these steps:

  • 1. The electron is a particle.
  • 2. The electron acts like a particle
  • 3. Sometimes the electron doesn’t act like a particle
  • 4. Sometimes the electron acts like a wave
  • 5. What is the location of the electron in QM?
  • 6. If the QM location is a probability distribution, what is the QM velocity?
  • 7. The location and velocity are both imprecise in QM.
