Study Notes
Max Planck's Life and Work
- Born in Kiel, Germany in 1858, the youngest of six children.
- Family moved to Munich when he was 9.
- Attended Maximilian gymnasium, showing aptitude for mechanics, mathematics, music.
- Inspired by a tutor to study physics.
- Earned doctoral degree from University of Munich at 21, thesis on thermodynamics.
- Became professor of theoretical physics at University of Berlin in 1889, remained until retirement in 1926.
Planck's Quantum Theory
- Planck's quantum theory challenged classical physics ideas.
- Proposed energy is emitted not continuously, but in discrete packets called "quanta."
- This fundamentally changed understanding of the subatomic world.
- This work revolutionized physics and is a foundational concept for 20th-century science.
Black Body Radiation
- Physicists in the 1890s struggled to explain black body radiation, the absorption/emission of light by objects.
- German physicist Gustav Kirchhoff defined a black body as a hypothetical object that absorbed all electromagnetic radiation falling on it.
- When heated, black bodies radiate energy in the form of electromagnetic waves across different wavelengths (visible, ultraviolet, infrared etc).
- Experimental observations of black body radiation did not match predictions from classical thermodynamics.
- Planck's work focused on this mismatch, leading to his quantum theory.
- Planck's work aimed to match his theory with observations of black body radiation.
- Planck's discoveries were recognized with the Nobel Prize in physics 74 times.
- Max Planck's theory was based on the bold notion that energy was available only in fixed packets (quanta), paving the way for modern technologies such as solar power.
