| Bemærkning | Ernest Rutherford (1871 - 1937) was born in Nelson, New Zealand. He graduated from the University of New Zealand, Wellington in 1893 with a double first in Mathematics and Physical Science. In 1894, he was awarded an 1851 Exhibition Science Scholarship, enabling him to go to Trinity College, Cambridge, as a research student at the Cavendish Laboratory under J.J. Thomson.
In 1907 he became Langworthy Professor of Physics at the University of Manchester. Rutherford researched the properties of radium emanation and of alpha rays and, in conjunction with H. Geiger, a method of detecting a single alpha particle and counting the number emitted from radium was devised. In 1910, his investigations into the scattering of alpha rays and the nature of the inner structure of the atom which caused such scattering led to the postulation of his concept of the “nucleus”, his greatest contribution to physics. According to him practically the whole mass of the atom and at the same time all positive charge of the atom is concentrated in a minute space at the centre. In 1912 Niels Bohr joined him at Manchester and he adapted Rutherford’s nuclear structure to Max Planck‘s quantum theory and so obtained his theory of atomic structure. An inspiring leader of the Cavendish Laboratory at Cambridge from 1919, he steered numerous future Nobel Prize winners towards their achievements. He won the Nobel Prize for Chemistry in 1908. Ralph Fowler (1889 -1944) was a British physicist. In December of 1906, he won a Major Scholarship to Trinity College, Cambridge graduating in 1909. In 1913 he was awarded a Rayleigh Prize in Mathematics. In 1919 after military service he returned to Trinity and was appointed College Lecturer in Mathematics in 1920. In 1921, Ralph married Eileen, the only daughter of Ernest Rutherford (d. 1930). 1926 marked the publication of his most seminal individual paper which linked the gaseous degenerate state obeying quantum statistics. During the next two decades he produced papers on spectroscopy, physical chemistry, solid-state physics, and magnetism in materials. He eventually took up a post in the Cavendish Laboratory at Cambridge and, in 1932, he was elected to the newly created Plummer Chair of Theoretical Physics. |
