James Chadwick
James Chadwick was born on October 20, 1891. During the first world war, Chadwick was away in Germany on a scholarship, which resulted in him being detained and kept as a civillian prisoner of war for four years. After his release we returned to his home of England to carry out research at Cambridge University. Soon after he was appointed assistant director of the lab by none other than Ernest Rutherford. Chadwick's personal research was focused on radioactivity. Chadwick's own contribution to science prooves the existence of the neutron and as constiderably sped-up reasearch in nuclear physics today.
Niels Bohr
Niels Bohr is widely considered to be the pioneer of Modern Physics. He was born on October 7, 1885 in Copenhagen, Denmark and as made a significant contribution to science today, contributions such as helping the understanding of the structure of properties of atoms. He was the winner of the 1922 Nobel Prize for physics solely for his work on the atomic structure. He also holds a doctorate in this area of science. He described the way atoms emit radiation, by suggesting that when an electron jumps from an outer orbit to an inner one, that it emits light. This theory was later expanded into the area of Quantum Physics.

is a false statement. But the opposite of a profound truth may well be
another profound truth.”

Sir Joseph John Thomson
Joseph John Thomson was born in Cheetham
Hill, Manchester, on December 18, 1856. In 1870 he enrolled at Owens
College, and in 1876 transferred to Trinity College, Cambridge as a
minor scholar. In 1897 the British physicist conducted a series of
experiments, studying the nature of electric discharge in a high-vacuum
cathode-ray tube, and found the electron. This, at the time, was being
examined by various other scientists. Thomson received various
awards; in 1906 J.J. Thomson was awarded the Nobel Prize in Physics, "in
recognition of the great merits of his theoretical and experimental
investigations on the conduction of electricity by gases". Joseph was
knighted in 1908. J.J Thomson died August, 30 1940.
Ernest Rutherford
Ernest Rutherford was born in New Zealand in 1871. After winning a scholarship to Canterbury College, Christchurch, he began his reasearch into magnetic viscosity. Shortly, after he was accepted into Trinity College, Cambridge, where he carried out a series of experiments using wireless transmissions, he made the notible discovery of three types of uranium radiations. Later in 1907 he began work as a professor at Manchester University after reciving his Nobel Prize for chemisty. Ernest became president of the Royal Society from 1925 to 1930, before his death in 1937.
