This prototype was essentially a highly sensitive electrical device designed to count alpha particle emissions. . The Stasi, East Germany's secret police during the Cold War, supposedly used radiation to track enemies of the state. It was used to count alpha and beta particles. The Geiger-Marsden experiments were performed between 1908 and 1913 by Hans Geiger (of Geiger counter fame) and Ernest Marsden (a 20-year-old student who had not yet earned his bachelor's degree) under the direction of Ernest Rutherford. This is our collection of basic interesting facts about Geiger Counter. Hans Geiger invented the Geiger counter in 1911. Born in Germany on September 30, 1882--September 24, 1945 in Germany . A.C.Gilbert's science based toys were so popular that he was called 'the man who saved christmas' by the papers.For a year, his company sold a kids 'atomic energy lab' complete with Geiger counter, mini cloud chamber, and samples of several radioactive elements.

He preferred art, entering the School of Applied Arts in Zurich and creating works based on his adolescent love of Egyptian iconography like mummies and sarcophaguses. Geiger was born at Neustadt an der Haardt, Germany. - source. The eldest of five children, two boys and three girls, Geiger was educated initially at Erlangen Gymnasium, from which he graduated in 1901. A couple of months later he moved to Potsdam, dying there two months after the atomic bombings of Hiroshima and Nagasaki in Japan. He had only just started to show signs of improvement in his health when his home near Babelsberg was occupied in June of 1945. [8] Work was interrupted when Geiger served in the German military during World War I as an artillery officer from 1914 to 1918. He continued experimenting and improving the counter. The Geiger-Marsden experiments (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated. During the First World War he served as an officer. By using banks of Geiger counters and Bothe's method of coincidence it is possible to determine the angular distribution of cosmic rays. (b. Wrzburg, Germany, 5 December 1901; d. Munich, Federal Republic of Germany, 1 February 1976) . Geiger, H. and Mller, W.

Surratt was the first woman to be executed by the U.S. federal government. ." Before he was famous, He earned his doctorate in mathematics and physics from the University of Erlangen in 1906. Tweet This, Born in Bulgaria, I have lived in places like Germany, Belgium and Iraq, before settling down with my family in Luxembourg. In 1920, James Chadwick used a similar experimental setup to determine the Z value for a number of metals. Rutherford's description of the event as recorded by Wilson revealed its importance: "It was as though you had fired a fifteen-inch shell at a piece of tissue paper and it had bounced back and hit you." Wilhelm Ludwig Geiger, was a philology professor-Hans took part in an attempt to build an atomic bomb, during WWII-Geiger and J. M.

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). As these men were politically conservative, their decision to oppose the National Socialists was taken seriously, and seventy-five of Germany's most notable physicists put their names to the Heisenberg-Wien-Geiger Memorandum. Bohr united Rutherford's atomic model with the quantum theories of Max Planck to determine that electrons in an atom can only take discrete energy values, thereby explaining why they remain stable around a nucleus unless emitting or absorbing a photon, or light particle. He and his sister, Iris, who was seven years his senior, were treated kindly by their parents. "Geiger, Hans .
