The Physics of the Very Small

Quantum mechanics reveals the strange and wonderful world of atoms and subatomic particles, where probabilities reign and nothing is certain until measured.

Core Principles

• Wave-Particle Duality: Light and matter can behave as both waves and particles.
• Uncertainty Principle: You can't know both the position and momentum of a particle exactly.
• Quantization: Energy comes in discrete amounts (quanta).

Where It Matters

Quantum mechanics is behind lasers, transistors, and even the way the sun shines.

Famous Equation

The Schrödinger equation: \( i\hbar \frac{\partial}{\partial t} \Psi = \hat{H} \Psi \), which predicts the behavior of quantum systems.
