Hans Rudolph Giger (05.02.1940 - 12.05.2014) - Biography, Interesting The group splintered in 1942 after its members came to believe (incorrectly, as it would later transpire) that nuclear weapons would not play a significant role in ending the war. It has never been given to the same person more than once. Hans Geiger - Inventor of the Geiger-Mller counter Both of Rutherfords parents were taken as youngsters to New Zealand in the mid-nineteenth, Bohr, Aage Niels The eldest of five children, Geiger was educated first at Erlangen Gymnasium, from which he graduated in 1901. It was presented to the Reich Education Ministry in late 1936. In 1912, Geiger took up a professorship at the Physikalisch-Technische Reichsanstalt (PTR) in Berlin, where he was head of the radioactivity laboratory. They began experiments based on Rutherford's detection of the release of alpha particles (particles with "positive" electric charges) from radioactive substances (substances whose atoms give off particles of matter and harmful rays of energy). Here are some interesting facts about Hans Geiger: * During the World War II years, he was a member of the secret Uranium Club, a group of German scientists engaged in nuclear weapons research. 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. H. Geiger and J.M. Johannes Wilhelm Geiger was born in Neustadt ander-Haardt (now Neustadt ander-Weinstrasse), Rhineland-Palatinate, Germany, on September 30, 1882.

Extraordinary though they were, the results of the Geiger-Marsden experiments did not immediately cause a sensation in the physics community. Wilson noted that Dr. T. J. Trenn, a modern physics scholar, characterized Geiger's and Marsden's work of this period: "It was not the Geiger-Marsden scattering evidence, as such, that provided massive support for Rutherford's model of the atom. In J.J. Thomsons "plum pudding model" an atom comprises a number of negatively charged electrons in a sphere of uniform positive charge, distributed like blueberries in a muffin. By using banks of Geiger counters and Bothe's method of coincidence it is possible to determine the angular distribution of cosmic rays.

"Hans Geiger Then, in 1911 Geiger, with the assistance of Rutherford created the first edition of the Geiger counter. Thomson found that metals emitted negatively charged particles when illuminated with high-frequency light. . However, they unexpectedly found that a few of the particles were deflected or scattered upon contact with the atoms in the gold, indicating that they had come into contact with a very powerful electrical field. Resignation and sickness marked this period of his life. In the atomic era, the Geiger-Mller Counter, as it is officially known, is an indispensable piece of equipment for all radiation physicists. Since alpha particles can penetrate thin walls of solids, Rutherford and Geiger presumed that they could also move through atoms.
