The Alsatian-born American theoretical physicist Hans Albrecht Bethe (born 1906), prolific and creative contributor to several vital fields of nuclear physics, discovered the mechanism of energy production by stars (including the sun). Hans Bethe was...

Prior to 1938, scientists were puzzled about how stars produce their light and energy. One popular theory about the production of stellar energy relied on chemical combustion; others proposed gravitational forces or electrical fields. In 1938,...

Hans Bethe is one of the premier physicists of the twentieth century, and one of only a very small number whose understanding and contributions span nearly all of the subfields of physics. His achievements range widely through science, his most...

Hans Bethe, an only child, was born on July 2, 1906, in Strasbourg, when Alsace was part of the Wilhelminian empire. His father was a widely respected physiologist who accepted a professorship in Frankfurt when Hans was nine years old; his mother was a...

Hans Albrecht Bethe (1906–2005) was a Nobel physicist and leader in efforts to promote social and ethical responsibilities among scientists and engineers. Born in Strassburg, Germany (now Strasbourg, France), on July 2, Bethe received his...

1906- German-born American physicist who was awarded the 1967 Nobel Prize for Physics for contributions to nuclear reactions, especially for his 1939 theory describing stellar energy production. One of his many contributions to quantum electrodynamics...

It was just after the 1986 Challenger space shuttle disaster, and physicist Richard Feynman was among the researchers chosen to investigate it as part of the Rogers Commission.Once he met with NASA managers, Feynman had questions about some of the shuttle's designs. So he tracked...
