JAMES CHADWICK Nobel Prize in Physics for 1935

Who’s James Chadwick? Born in Cheshire, England 20th october 1921 Joseph Chadwick and Anne Mary Knowles

Manchester high school and Manchester University Honours School of Physics 2 years  Physical Laboratory in Manchester Interned in Ruhleben

Why did he won the Nobel Prize? Fundamental discovery: He proved the existence of neutrons

NEUTRONS Elementary particles devoid of an electrical charge Not overcome any electric barries Is capable of penetrating and splitting the nuclei of the elements

He prepared the way towards  uranium 235  the creation of the atomic bomb

Which was the historical approach? Just before the second World War started

Previous to the discovery 1900: emergence of a new Physics Detection of unexpected forms of radiations  Wilhelm Röntgen  Henri Becquerel  Marie and Pierre Curie  Rutherford and Soddy

Applications nowadays Applications in the earth science Applications in the energy Applications in the environment
