UNIT 6

ERNEST RUTHERFORD

(1871-1937)

Ernest Rutherford was born in New Zealand where he lived up to 1895. At the age of 19 after finishing school he entered the only New Zealand University founded in 1870. At that time there were only 150 students and 7 professors there. At the university Ernest took great interest in physics and developed a magnetic detector of radio waves. However, he was absolutely uninterested in the practical applications of his discoveries.

In 1895 Rutherford went to Cambridge where he con­tinued research under Thomson (1856—1940), the out­standing English physicist. There Rutherford studied the processes of ionization in gases and took great interest in the theory of radioactivity discovered by Becquerel (1852-1908), a world-known French physicist. For


               
 
about ten years Ernest Rutherford lived and worked in Canada. Later he lectured in leading universities in the USA and England from 1907 till 1919. Rutherford's famous work "The Scattering of Alpha and Beta Particles of Matter and the Structure of the Atom" dealt with so-called "atom models". All main Rutherford's works deal with the model of the atom. The split­ting of the atom has opened to man a new and enormous source of energy. The most important results have been obtained by splitting the atom of uranium. For working out the theory of radioactive disintegra­tion of elements, for determining the nature of alpha particles, for developing the model of the atom, Rutherford was awarded in 1908 the Nobel Prize in chemistry. Rutherford created a school of talented physicists in the field of atomic research, the Russian scientists P. Kapitza and Y. Kchariton were among his pupils. E. Rutherford died in 1937 at the age of 66.
