GENERAL INFO

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

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

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

PLANCK’S CHILDREN

He had 5 children

3 died very young

He lost his eldest son during WWI

His last son died during WWII

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

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

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

PL ANCK’S W OR K O N THE Q UANTU M THEO RY

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

PL ANCK’S W OR K O N THE Q UANTU M THEO RY

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

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
