The Case of Klaus Fuchs, Atomic Spy

The Case of Klaus Fuchs, Atomic Spy

On December 29, 1911, German-born British theoretical physicist and atomic spy Emil Julius Klaus Fuchs was born. In the time of the development of the atomic bomb at the Los Alamos National Laboratory, Fuchs was responsible for many significant theoretical calculations relating to the first nuclear weapons, and later, early models of the hydrogen bomb. In 1950, Fuchs was convicted of supplying information from the American, British, and Canadian Manhattan Project to the…

Arnold Sommerfeld – Quantum Theory and Famous Students

Arnold Sommerfeld – Quantum Theory and Famous Students

On December 5, 1868, German theoretical physicist Arnold Sommerfeld was born. Sommerfeld pioneered developments in atomic and quantum physics, and also educated and mentored a large number of students for the new era of theoretical physics. He served as PhD supervisor for more Nobel prize winners in physics than any other supervisor to date. He introduced the 2nd quantum number (azimuthal quantum number) and the 4th quantum number (spin quantum number). He…

Richard Hamming and the Hamming Code

Richard Hamming and the Hamming Code

On February 11, 1915, American mathematician Richard Wesley Hamming was born. Hamming’s work had many implications for computer science and telecommunications. His contributions include the Hamming code (which makes use of a Hamming matrix), the Hamming window, Hamming numbers, sphere-packing (or Hamming bound), and the Hamming distance. “The purpose of computation is insight, not numbers.” – Richard Wesley Hamming (1962) as quoted in [2] Richard Hamming – Youth and Education Richard Wesley…

Hans Bethe and the Energy of the Stars

On July 2, 1906, German and American nuclear physicist and Nobel Laureate Hans Albrecht Bethe was born. Bethe helped to shape classical physics into quantum physics and increased the understanding of the atomic processes responsible for the properties of matter and of the forces governing the structures of atomic nuclei. Hans Bethe Background Hans Bethe entered the University of Frankfurt in 1924, majoring in chemistry. However, after a few semesters, he was advised…

Hans Geiger and the Invention of the Geiger-Müller Counter

On September 30, 1882, German physicist Johannes Wilhelm Geiger was born. He is best known as the co-inventor of the Geiger counter and for the Geiger–Marsden experiment which discovered the atomic nucleus. Hans Geiger – Early Years Geiger was born at Neustadt an der Haardt, Germany. He was one of five children born to the Indologist Wilhelm Ludwig Geiger, who was a professor at the University of Erlangen. In 1902, Hans Geiger…

Frank Spedding and the Rare Earth Elements

On October 22, 1902, Canadian American chemist Frank Spedding was born. Spedding was a renowned expert on rare earth elements, and on extraction of metals from minerals. His uranium extraction process helped make it possible for the Manhattan Project to build the first atomic bombs. Youth and Education Spedding was born in Hamilton, Ontario, Canada, the son of Howard Leslie Spedding and Mary Ann Elizabeth Marshall. In 1918, the family moved to…
