The paper was presented to Hitler's Education Ministry in late 1936. At the University of Manchester, Geiger conducted research with Ernest Rutherford. Johannes Wilhelm "Hans" Geiger (/ar/; German: [a]; 30 September 1882 24 September 1945) was a German physicist. Geiger was challenged by the haphazardness of their methodology to invent a more precise technique. the existence of light quantum, or packets of energy. That's because matter is usually electrically neutral; so if atoms contain negatively charged particles, they must also contain a source of equivalent positive charge to balance out the negative charge. In 1933 received his doctorate at the University of Tubingen where his doctoral advisor was Hans Geiger, inventor of the Geiger counter. These experiments revealed that the angle of scattering of the -particle was proportional to the square of the charge of the atomic nucleus, or Z, according to the book (opens in new tab) "Quantum Physics of Matter," published in 2000 and edited by Alan Durrant.
