Born: 1891 Died: 1974

James Chadwick was born in Manchester, England in the year 1891. Chadwick studied at the University of Manchester with Ernest Rutherford. Chadwick wanted to further his studies in Germany under Hans Greiger. Shortly upon his arrival, World War I broke out and Chadwick was arrested. While in prison, he was able to persuade the gaurds into allowing him to set up a lab and start a science club. He had to use materials such as tin foil and wood just to make a microscope. Chadwick was specifically interested in studies having to deal with radioactivity. Chadwick discovered that there was a radioactive toothpaste on the market in Germany and convinced the gaurds to allow him to use that towards his experiments. Chadwick got his PhD with Ernest Rutherford in 1921. In 1932, Chadwick released a paper called,'The Existence of Atoms." This discover allowed many other discoveries to occur (Ex:Nuclear Fission). Chadwick passed away in 1974. =Werner Heisenberg= = = == [] [] Werner Heisenberg was born on December 5, 1901 in Wurzburg, Germany.Heisenberg studied physics at the University of Munich and received his PhD. Heisenberg worked with Niels Bohr at the University of Copenhagen where Heisenberg became a professor at the age of 26. During WWII, American troops sent him to England as a prisoner for his affiliation with the Nazis; he was working on an atomic bomb project. He eventually was let go and returned to Germany. In 1925, at the age of 23, his theory of quantum mechanics was published. He was awarded the Nobel Prize in 1932. One of his other famous works is the //principle of uncertainty// which states that errors can not be ignored in the studies of atoms and they must be accounted for in some manner. Heisenberg received many awards, was knighted, and contributed to many organizations. He was a married manand had seven kids. He enjoyed classical music and playing the piano. In 1976, Heisenberg passed away. = = =Erwin Schrodinger= = = == = =

= = Erwin Schrodinger was born on August 12, 1887 in Vienna, Austria. He was an only child living with his father, who was a chemist and ver well educated man. Schrodinger atteneded the University of Vienna. Around the end of his time at the university, he joined the military and became an auxilary officer during WWI. After the war Schrodinger worked at many universities and publish many papers including; specific heat and solids, problems of thermodynamics and of atomic spectra, and physiological studies of colour. In 1926, Schrodinger discover a wave equation and was awarded the Nobel Prize in 1933. On January 4, 1961, Schrodinger passed away leaving behind his wife whom was there with him until the very end. Schrodinger developed the electron cloud model of the atom. The basis of it was that the nucleus was the center of the atom with electron probability clouds around it. All that could be said was that an electron was somewhere in that probability cloud at any given moment. [][] []
