Summary
Quantum physics describes atoms and smaller — where particles act like waves and outcomes are probabilistic.
Light and matter come in quanta (packets). Measuring changes what you see. Entanglement links distant particles strangely but doesn't send usable FTL messages.
- Wave–particle duality: electrons and photons both.
- Uncertainty: can't pin down position and momentum sharply at once.
- Tech: lasers, MRI, semiconductors, quantum computers (emerging).
