1. MAX PLANCK By: Tyler Brown and Devontae Dixon http://www.youtube.com/watch?v =R9sMxEnbha0&edufilter=FwNI MIqIDIQYAexPZDE7XA

2. GENERAL INFO  Full Name: Max Karl Ernst Ludwig Planck  Birthplace: Kiel, Germany  Birthdate: April 23, 1858  Father: Julius Wilhelm  Mother: Emma Planck

3. PLANCK’S FATHER  Planck’s father was Professor of Constitutional Law for the University of Kiel  He was later Professor of Constitutional Law for the University of Kiel

4. PLANCK’S MARRIAGES  He was married twice, He married a childhood friend Marie Merck in 1885 he was married until 1909 when she died  He remarried to Marie’s cousin Marga von Hosslin

5. PLANCK’S CHILDREN  He had 5 children  3 died very young  He lost his eldest son during WWI  His last son died during WWII

6. PLANCK’S COLLEGE YEARS  Planck studied at the University of Munich and the University of Berlin  He was taught by Professors Kirchhoff and Helmholtz  He received his doctorate of philosophy at the University of Munich in 1879

7. PLANCK’S COLLEGE YEARS  From 1880 to 1885, he was Privatdozent in Munich  In 1889 he replaced Kirchhoff as Professor at Berlin University  In 1894 the Prussian Academy of Sciences made him a member and he became a permanent secretary from 1912-1926

8. PLANCK’S EARLY ACCOMPLISHMENTS IN LIFE  Planck’s early work in science was on thermodynamics  He was also interested on the problems of radiation processes  These processes led him to the problem of energy in the spectrum of full radiation

9. PLANCK’S WORK ON THE QUANTUM THEORY  Max Planck discovered that energy is quantized  This means that energy increases occur in steps not on a smooth curve  This means that an atom’s electrons can’t jump around they must stay in a certain region around the nucleus (depending on the electron’s energy)  Planck assumed that the radiation energy is emitted in discrete packets called quanta rather than continuously

10. PLANCK’S WORK ON THE QUANTUM THEORY  He discovered that the energy E of the quantum is related to the frequency V by E = hv. The quantity (h), now known as the Planck constant, is a constant with the approximate value of 6.626 X 10^-34 Js

11. THE END OF MAX PLANCK'S LIFE  Towards the end of his life he received the Nobel Peace Prize for physics  He died on October 4, 1947
