1. MAX PLANCK

2. PERSONAL STORY Born in Kiel Germany April 23 rd 1858 Died at Göttingen on October 4 th 1947 University of Munich and Berlin Doctorate of Philosophy at Munich Son executed

3. 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

4. EXPERIMENTS/STUDY Thermodynamics Quantum Theory Energy radiation of heated solids

5. 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
