Sir Joseph Rotblat and the Nuclear Test Ban

Sir Joseph Rotblat and the Nuclear Test Ban

On November 4, 1908, Polish physicist and recipient of the Nobel Peace Prize Joseph Rotblat was born. Rotblat was the only physicist to leave the Manhattan Project (1942–46) on the grounds of conscience. Rotblat’s work on nuclear fallout was a major contribution toward the ratification of the 1963 Partial Nuclear Test Ban Treaty. A signatory of the Russell–Einstein Manifesto (1955), he was secretary-general of the Pugwash Conferences on Science and World Affairs from their…

John Ray Dunning and the Manhattan Project

On September 24, 1907, US-American physicist John Ray Dunning was born. Dunning played key roles in the Manhattan Project that developed the first atomic bombs. He specialized in neutron physics, and did pioneering work in gaseous diffusion for isotope separation. John Ray Dunning – Early Years John Ray Dunning was born in Shelby, Nebraska, USA, the son of Albert Chester Dunning, a grain dealer, and his wife Josephine. He graduated from Shelby High…

Frederick Reines’ Chase for the Ghost Particle

Frederick Reines’ Chase for the Ghost Particle

On March 16, 1918, American physicist and Nobel Laureate Frederick Reines was born. He is best known for his co-detection of the neutrino with Clyde Cowan in the neutrino experiment. The neutrino is a subatomic particle, a tiny lepton with little or no mass and a neutral charge which had been postulated by Wolfgang Pauli in the early 1930s but had previously remained undiscovered. Reines shared the Nobel Prize with physicist Martin…

Hans Geiger and the Invention of the Geiger-Müller Counter

On September 30, 1882, German physicist Johannes Wilhelm Geiger was born. He is best known as the co-inventor of the Geiger counter and for the Geiger–Marsden experiment which discovered the atomic nucleus. Hans Geiger – Early Years Geiger was born at Neustadt an der Haardt, Germany. He was one of five children born to the Indologist Wilhelm Ludwig Geiger, who was a professor at the University of Erlangen. In 1902, Hans Geiger…

Ernest Rutherford Discovers the Nucleus

Ernest Rutherford Discovers the Nucleus

On December 20, 1910, New Zealand born physicist Ernest Rutherford made his seminal gold foil experiment which led to first insight about the nature of the inner structure of the atom and to the postulation of Rutherford‘s concept of the “nucleus“, his greatest contribution to physics. Most interestingly, Rutherford made his greatest discovery after receiving the Nobel Prize in chemistry in 1908. “When we have found how the nucleus of atoms is…

James Chadwick and the Discovery of the Neutron

On February 27, 1932, English physicist and Nobel Laureate Sir James Chadwick published an article in the scientific journal ‘Nature‘ about the discovery of the neutron, a previously unknown particle in the atomic nucleus. Youth and Education Chadwick was born in Bollington, near Manchester. His parents were John Joseph Chadwick and Mary Anne Knowles. He first attended the Bollington Cross C of E Primary School and later the Central Grammar School for Boys…
