This is my first time to learn Quantum Mechanics, Quantum Mechanics is a very cool discipline to me.

1. Introduction to Superposition

Empirical fact: Electron is black or white, hard or soft.

Color and hardness is unrelated.

After you measured the color/hardness of a electron once, you are still not sure about its color/hardness before it’s measured second time.
