Do we live in a Quantum World? - Ask a Spaceman!
Dr. Paul M. Sutter・5 minutes read
Quantum mechanics and classical physics have distinct rules governing subatomic and everyday behavior, respectively, with Niels Bohr proposing complementary properties to bridge the gap between the two realms without replacing one with the other.
Insights
- Quantum mechanics explains the behavior of subatomic particles through concepts like wave-particle duality and the Heisenberg uncertainty principle, contrasting with classical physics that governs larger objects using principles like electromagnetism and Newton's gravity.
- Niels Bohr introduced the idea of complementary properties in quantum physics, emphasizing pairs like wave-particle duality and position-momentum, illustrating the fundamental differences between quantum and classical physics while proposing the correspondence principle as a bridge between these two realms.
