Study Notes
Max Planck's Quantum Theory
- Planck's quantum theory revolutionized classical physics
- Energy is emitted in fixed packets called "quanta" instead of continuously
- This fundamentally altered the understanding of the subatomic world
Planck's Life and Career
- Born in Kiel, Germany, the youngest of six children
- Moved to Munich at age 9 and attended Maximilian gymnasium
- Displayed aptitude for mechanics, mathematics, and music
- A tutor sparked his interest in physics; he pursued a doctorate, specializing in thermodynamics
- Received a doctoral degree from the University of Munich in 1879
- Became a professor of theoretical physics at the University of Berlin in 1889, holding the position until retirement in 1926
Black Body Radiation
- Physicists struggled to explain black body absorption and emission in the 1890s
- Black body radiation is the hypothetical body that absorbs all electromagnetic radiation
- He focused on black body radiation to reconcile theory with observation
- Experimental measurements of wavelengths produced by hot objects didn't match classical thermodynamics predictions
Planck's Breakthrough
- Investigated black body radiation in the 1890s, calculating vibration frequencies of atoms
- Developed a radiation distribution law in 1900
- Introduced the concept of energy quanta
- His work helped establish the connection between energy and the quantum world
Influence on Einstein
- In 1905, Planck helped promote Einstein's theory of relativity
- He played a key role in establishing Einstein's work in Germany
- Created a new professorship at the University of Berlin for Einstein in 1914
Recognition of Planck's Work
- Awardee of the 1919 Nobel Prize in Physics for the discovery of energy quanta
