Quantum Mechanics in 8 sentences:

1. Particles on a microscopic level can be described by wave functions.
2. Heisenberg Uncertainty Principle: position and momentum cannot be known simultaneously.
3. It explains superposition, where a particle can exist in multiple states simultaneously.
4. Quantum entanglement enables instant communication between particles, regardless of distance.
5. It explains the probability of subatomic particles behavior
6. Measurement collapses wave function, causing definite state of a particle.
7. Observing a particle affects its behavior.
8. Energy is quantized, meaning it can only exist in certain discrete amounts.
