Study Notes
Max Planck and Quantum Physics
- Planck investigated black body radiation's intensity dependence on temperature and frequency.
- Physicists initially assumed continuous oscillation but Planck found atoms could only vibrate at specific frequencies (whole-number multiples).
- The constant frequency Planck found is known as Planck's constant (h).
- Planck's constant is a fundamental physical constant, with a consistent value across the universe.
Paul Dirac and Quantum Mechanics
- Dirac was a prominent English physicist focusing on quantum mechanics.
- His Dirac equation predicted the existence of antimatter particles like positrons.
- He studied Werner Heisenberg's work on matrix mechanics.
- Dirac observed parallels between quantum and classical theories.
- He created quantum field theory and calculated the prediction for antimatter particles.
- He was awarded the Nobel Prize in Physics in 1933, together with Erwin Schrödinger.
- Dirac's work revolutionized understanding of quantum mechanics.
