Arthur Compton Biography - Childhood, Life Achievements & Timeline

The Nobel Prize in Physics 1927 was divided equally between Arthur Holly Compton ( 1892 – 1962 ) “for his discovery of the effect named after him” This discovery confirmed the dual nature of electromagnetic radiation as both a wave and a particle. 

and Charles Thomson Rees Wilson “for his method of making the paths of electrically charged particles visible by condensation of vapour.”

A Century of Quantum Physics: Arthur Compton

The benefits of science are not only material ones. The truths that science teaches are of common interest the world over.

The Language of Science is universal, and is a powerful force in bringing the peoples of the world closer together.

French physicist Jean Baptiste Perrin (1870-1942) helped to prove that atoms and molecules exist, especially for his discovery of sedimentation equilibrium , an achievement that earned him the 1926 Nobel Prize in physics.

Born: 30 September 1870, Lille, France

Died: 17 April 1942, New York, NY, USA

Affiliation at the time of the award: Sorbonne University, Paris, France


During the 1880s atoms and molecules became important scientific concepts, but whether or not they actually had a physical existence was still a matter of dispute. Jean Perrin maintained that if molecules were real, particles blended into a liquid should not all sink to the bottom but should distribute themselves throughout the liquid. In 1908 he could substantiate this through experimentation.

He also substantiated Albert Einstein’s theory that Brownian motion – the random movement of small particles in a liquid – was due to collisions between the particles and molecules in…
