Fill-in-the-Blank Questions

1. The principle that states it is impossible to precisely measure both the position and momentum of a particle simultaneously is known as the .

2. According to quantum mechanics, the refers to the process by which a quantum system transitions from a superposition of states to a single observable state when measured.

3. The mathematical representation of the quantum state of a system is called the function.

4. In quantum mechanics, particles can tunnel through barriers they classically shouldn't be able to cross due to the phenomenon known as tunneling.

5. In the quantum realm, the view that reality is fundamentally probabilistic rather than deterministic is a significant departure from classical theory.
