James Chadwick

Biography

It is presented to the Université of Manchester in 1907 with an aim of becoming a Mathématicien, but it is found, by accident, surrounded by students for the inscription with major in physics. Too much constrained to acknowledge its error, it remains in the file and thus began a prolific career as physicist. He works, inter alia, under the eye attentive of Ernest Rutherford during his two last years at this university. In 1913, it receives its license in science and leaves the city to go to Germany where it works with the professor Hans Geiger.

During the First World War, Chadwick is arrested in Germany and is imprisoned in a stable which is used as camp of internment. Released at the end of the war, it immediately turns over to the the United Kingdom in order to once again lead research under the orders of professor Rutherford to the Université of Cambridge. Meanwhile, this last tried out several things and speculates that it must exist a subatomic particle without load. Chadwick thus undertakes a series of experiments. He is elected highly skilled member of Gonville of 1921 with 1925. He becomes assistant research director in the laboratories of Cavendish in 1923. In 1925 it marries Aillen Stewart-Brown of Liverpool. They have binoculars together and live with Denbigh in the north of the Wales. In 1927, he is elected highly skilled member with the Royal Society, which decrees to him the Médaille Hughes in 1932.

During an experiment where it bombards Béryllium with particles α, it notices an unknown radiation which ejects protons of the core. Chadwick concludes from it that these radiations are made up of particles of mass roughly equal to the proton but without electric charge, the Neutron S. This discovery is one of most important in experimental physics.

In 1935 it becomes teaching with the Université of Liverpool. Chadwick was the first in the United Kingdom to conceive the possibility of developing the atomic bomb. Between 1943 and 1945, it passes the major part of its time to the the United States, mainly in the National laboratory of Los Alamos, where the first nuclear bomb is designed.

It is named knight in 1945, and becomes thus Sir James Chadwick. He is prize winner of the Médaille Copley in 1950 and of the Franklin Médaille in 1951.

He dies at the 82 years age. One can regard it as one of the physicists being distinguished more during the 20th century.
