MAX PLANCK

PERSONAL STORY• Born in Kiel Germany April 23rd 1858

• Died at Göttingen on October 4 th 1947

• University of Munich and Berlin

• Doctorate of Philosophy at Munich

• Son executed

IDEA OF ATOM• Oscillating atoms absorb and release energy in quanta ( small energy packets or

bundles)

• Energy equals frequency times Planck’s constant. E=hv

• Planck’s constant is 6.626x10-34 J*s

• Energy packets are released only in whole units

EXPERIMENTS/STUDY• Thermodynamics

• Quantum Theory

• Energy radiation of heated solids

SCIENTIFIC CONTRIBUTION• Proposed energy can behave like a particle

• Einstein used the quantum theory to explain the photoelectric effect

• Bohr used the quantum theory to explain the bright line spectrum

• Quantum theory was the first step to explain why atoms didn’t collapse like Rutherford predicted
