Max Planck, born in Kiel in 1858, was a reserved, conservative scholar and yet became, against his will, the revolutionary who ushered in a completely new physics. He had actually been advised against studying physics, as it was "essentially complete". Planck would prove the opposite. To solve a stubborn puzzle of heat radiation, in 1900 he ventured a radical assumption: energy is not given off in arbitrary amounts but only in tiny, indivisible portions: quanta. With that, quantum physics was born, transforming our picture of atoms, light and matter forever. The constant of nature he introduced, the Planck constant h, is among the most important numbers in physics. In 1918 Planck received the Nobel Prize. His life was overshadowed by grievous blows of fate: he lost several children, and his son Erwin was executed by the Nazis in 1945 for alleged involvement in the plot to assassinate Hitler. Planck nonetheless stayed in Germany and tried to save science through the darkest years. In his honour, the largest German research organisation today bears the name Max Planck Society. He died in 1947.

quanta
Not in arbitrary amounts.
💡 Did you know? Planck realised that energy is released only in tiny „packets“ (quanta): against all intuition of the time.
Planck constant
One of the most important numbers in physics.
💡 Did you know? The „Planck constant“ is one of the most fundamental constants in nature.
1918
For founding quantum theory.
💡 Did you know? Planck received the 1918 physics Nobel for discovering energy quanta.

Max Planck
Max Planck was a German physicist whose quantum hypothesis founded modern physics.
💡 Did you know? He at first considered his own revolutionary idea of energy quanta a mere mathematical stopgap.
