Beschreibung The Neutron and the Bomb: A Biography of Sir James Chadwick (English Edition)
James Chadwick (1891-1974) came from a humble background: his father was a cotton spinner. He was accepted in the physics department of Sir Ernest Rutherford at Manchester University in 1908 on a scholarship, and soon started publishing new findings about radioactivity. This led to a traveling scholarship to Berlin, where he made the important discovery of the continuous spectrum of β-particles. When the World War I broke out, Chadwick was interned by the Germans as an enemy alien for the next four years, but continued experiments in the prison camp.On his return to England in broken health, Rutherford invited Chadwick to join the Cavendish Laboratory in Cambridge where he became Rutherford’s deputy and oversaw much groundbreaking physics research over the next 15 years. Chadwick concentrated on finding evidence for the neutron, an uncharged nuclear particle whose existence was first proposed by Rutherford in 1920. Having noticed anomalous results from the Curie laboratory in Paris in 1932, Chadwick used simple bench-top apparatus to convince himself, after weeks of intense observations, that he had definite evidence for the existence of the neutron. The Nobel Prize for physics followed in 1935; that year he moved to Liverpool University to head his own department.At the outbreak of World War II, the feasibility of atomic bombs of unprecedented explosive power was already being discussed. Chadwick drafted the British MAUD committee's historic reports in the summer of 1941 which concluded that atomic bombs were indeed feasible with sufficient industrial capacity. In wartime Britain this was impossible, but in 1943 Chadwick moved to the US as head of the British scientists working on the Manhattan Project. He formed an unlikely alliance with its leader, General Leslie Groves, and became an adroit scientist-diplomat. Witnessing the first explosion of a plutonium-fueled device at the Trinity Test shattered him. Chadwick believed that dropping atomic bombs on Japanese cities was justified but the development of nuclear weapons as an unintended consequence of his discovery of the neutron caused him deep personal anguish.“Until this excellent book by Andrew Brown, [Chadwick] has remained the most shadowy of the atomic scientists who, for better or worse, gave the human species mastery over nuclear energy.” — Nigel Calder, New Scientist“Andrew Brown’s biography beautifully reveals [Chadwick’s] scientific, diplomatic and personal achievements.” — Roger H Stuewer, Physics Today“I can warmly recommend this book to all interested in the life of a remarkable scientist who played a crucial role in a formative period of the modern world.” — Hermann Bondi, Times Higher Education Supplement“This is the biography of a physicist who made one of the most important discoveries in nuclear physics, but retained to his old age the shyness of a young lad... Andrew Brown takes us through Chadwick’s life as an adventure... I found it a very good read.” — Hans Bethe, American Journal of Physics“The tale of so sterling a character, even when told as well as in this book, may be a little short on light moments, but any reader interested in the evolution of physics from an academic passion to a leading role on the world stage will find it a fascinating story and a worthy tribute to a great scientist.” — Brian Pippard, Nature“... makes absorbing reading... more than the life story of a remarkable man... unfolds the tremendous transformation that science underwent in the 20th century.” — Joseph Rotblat“… avidly researched and artfully written... This biography... blends elegantly direct scientific descriptions with often witty episodes and character summaries.” — William Lanouette, Bulletin of the Atomic Scientists

James Chadwick Atomic Theory / Sciencing ~ The Chadwick atomic theory arose from James Chadwick's discovery of the neutron. Scientists now know that the nucleus of the atom contains both positively charged protons and neutral neutrons, which have the same mass. Chadwick's discovery led directly to the development of the atomic bomb.
James Chadwick / Atomic Heritage Foundation ~ Chadwick is best known for his discovery of the neutron in 1932. A neutron is a particle with no electric charge that, along with positively charged protons, makes up an atom's nucleus. Bombarding elements with neutrons can succeed in penetrating and splitting nuclei, generating an enormous amount of energy. In this way, Chadwick's findings were pivotal to the discovery of nuclear fission, and ultimately the development of the atomic bomb. For more on Chadwick's scientific contributions .

Neutron - Wikipedia ~ The neutron is a subatomic particle, symbol n or n 0, which has a neutral (not positive or negative) charge and a mass slightly greater than that of a proton.Protons and neutrons constitute the nuclei of atoms.Since protons and neutrons behave similarly within the nucleus, and each has a mass of approximately one atomic mass unit, they are both referred to as nucleons.
