About
Quantum mechanics, developed between 1900 and 1930 by Planck, Bohr, Heisenberg, Schrödinger, and Dirac, describes the behavior of matter and energy at the smallest scales. In the quantum world, particles behave as waves, exist in superpositions of multiple states simultaneously, and are connected across any distance by entanglement. Measurement itself changes what is measured.
Despite its philosophical strangeness, quantum mechanics is the most precisely tested theory in science — verified to 10 decimal places. It underpins lasers, semiconductors, MRI machines, atomic clocks, and nuclear reactions. Without quantum mechanics, there would be no modern electronics, no smartphones, no computers.
# Top 10 Quantum Mechanics facts
- 1Quantum mechanics predicts probabilities, not certainties — Einstein called this 'spooky action at a distance'
- 2The double slit experiment shows a single electron can interfere with itself — passing through two holes simultaneously
- 3All modern electronics depend on quantum mechanics — transistors work by quantum tunneling
