He discovered that all isotopes have masses nearly to whole numbers and by finding this out he received the Nobel Prize.
His model became the basis for the quantum theory and he explained that outer orbits in an atom could hold more electrons than the inner orbits.
He states that one can never know the exact location and energy of an electron simultaneously.
Cockcroft and Walton`s invention is used today in x-ray machines, televisions and photocopiers. Due to this invention they both won a Nobel Prize.
He formulated the Dirac equation which describes the behaviour of fermions and predicted the existence of antimatter.
He developed a number of fundamental results in quantum theory using mathematical equations.
He worked with the military to create atomic bombs and these achievements lead to the awarding of Nobel Prize.
They discovered when Uranium is bombarded with neutrons, demonstrated the unknown phenomenon of nuclear fission.
He discovered the investigation of ten transuranium elements and the discovery of dozens of new isotopes produced using Berkeley’s cyclotrons.
He created the world`s first nuclear reactor which is known as the Chicago Pile-1.
