  Werner Heisenberg - Wikipedia, the free encyclopedia
Werner Karl Heisenberg (December 5, 1901 – February 1, 1976) was a celebrated German physicist and Nobel laureate, one of the founders of quantum mechanics.
In 1957 Heisenberg together with Otto Hahn, Max von Laue, Carl Friedrich von Weizsäcker and Max Born formulated and signed a protest against nuclear arming of the German Armed Forces and world-wide nuclear armaments, the so-called "Göttingen Declaration of the German Nuclear Physicists".
In it, an angry Bohr relates that Heisenberg, in their 1941 conversation, did not express any moral problems with the bomb making project, that Heisenberg had spent the past two years working almost exclusively on it, and that he was convinced that the atomic bomb would eventually decide the war.

 Heisenberg, Werner
Heisenberg was willing to sacrifice the idea of discrete particles moving in prescribed paths (neither particles nor paths could be observed) in exchange for a theory that would deal directly with experimental facts and lead to the quantum conditions as consequences of the theory rather than ad hoc stipulations.
Heisenberg used the new matrix mechanics to interpret the dual spectrum of the helium atom (that is, the superposed spectra of its two forms, in which the spins of the two electrons are either parallel or antiparallel), and with it he predicted that the hydrogen molecule should have analogous dual forms.
From 1927 to 1941 Heisenberg was professor at the University of Leipzig.

 Heisenberg, Werner (Karl)
Heisenberg was concerned not to try to picture what happens inside the atom but to find a mathematical system that explained it.
Heisenberg also was able to predict from studies of the hydrogen spectrum that hydrogen exists in two allotropes – ortho-hydrogen and para-hydrogen – in which the two nuclei of the atoms in a hydrogen molecule spin in the same or opposite directions respectively.
In 1927 Heisenberg used the Pauli exclusion principle, which states that no two electrons can have identical sets of quantum numbers the same, to show that ferromagnetism (the ability of some materials to acquire magnetism in the presence of an external magnetic field) is caused by electrostatic interaction between the electrons.

Heisenberg was the head of Nazi Germany's nuclear energy program, though the nature of this project, and his work in this capacity has been heavily debated.
Heisenberg was born in Würzburg, Germany, the son of Dr. August Heisenberg and Annie Wecklein.
Part of this interpretation is based on the fact that Heisenberg did not champion the project to Albert Speer in a way which got it any attention or very much funding (which of the ALSOS project interpreted as being partially because Heisenberg himself was not fully aware of the feasibility of an atomic bomb).

Werner Karl Heisenberg was born in Wuerzburg, Germany, on December 5, 1901, and grew up in academic surroundings, in a household devoted to the humanities.
For over a year Heisenberg was attacked in the SS newspaper, which referred to him as a "white Jew." The attack became so threatening that Heisenberg's mother, who had a slight connection to Himmler's family, wrote to Himmler's mother asking Himmler to intercede.
Heisenberg spent the final years of his career trying to derive the properties of such elementary particles as electrons, protons, and so on, from a departure from quantum field theory by having the field itself construct its own particles.

 Werner Heisenberg: controversial scientist (December 2001) - Physics World - PhysicsWeb
Werner Karl Heisenberg was born on 5 December 1901 in Würzburg, northern Bavaria, and moved to Munich at the age of nine when his father became a professor of Greek studies at the university.
Heisenberg gained government acceptance after the outbreak of the Second World War, and was entrusted by the Ministry of Education with the scientific directorship of the Kaiser Wilhelm Institute of Physics in Berlin, together with Otto Hahn.
Heisenberg's role in the play is less heroic, however, and his character is embedded in an artistic maze of uncertainties that allude to both quantum uncertainty and the historical uncertainty that exists as a result of the lack of documentary evidence about the meeting in 1941.

Werner Karl Heisenberg, (December 5, 1901 - February 1, 1976), was a celebrated physicist and Nobel laureate, one of the founders of quantum mechanics.
Heisenberg himself attempted to paint this picture after the war, and Thomas Power's book "Heisenberg's War" and Michael Frayn[?]'s play "Copenhagen" adopted this interpretation.
Most historians of science take this as evidence that the previous interpretation of Heisenberg's resistance was wrong, but some have argued that Bohr profoundly misunderstood Heisenberg's intentions at the 1941 meeting.

It was probably due to his influence that Heisenberg remarked, when the Japanese physicist Yukawa discovered the particle now known as the meson and the term "mesotron" was proposed for it, that the Greek word "mesos" has no "tr" in it, with the result that the name "mesotron" was changed to "meson".
Heisenberg went to the Maximilian school at Munich until 1920, when he went to the University of Munich to study physics under Sommerfeld, Wien, Pringsheim, and Rosenthal.
During 1955 Heisenberg was occupied with preparations for the removal of the Max Planck Institute for Physics to Munich.

Werner Karl Heisenberg, physicist, philosopher, and public figure, helped to establish the modern science of quantum mechanics, out of which came the famous indeterminacy principle.
According to Heisenberg, what was revealed by active observation was not an absolute datum, but a theory-laden datum; i.e., relativized by theory and contextualized by observational situations.
Widely acknowledged as one of the seminal thinkers of the 20th century, Heisenberg was awarded the Nobel Prize for Physics for 1932 and was honoured with the Max Planck Medal, the Matteucci Medal, and the Barnard College Medal of Columbia University.

Werner Karl Heisenberg was born on December 5, 1901 in the city of Würzburg in the southern German principality of Bavaria.
Werner’s grade was biased because he talked about theoretical physics instead of experimental physics, which was not accepted in those days.
At this point in history, Heisenberg’s parents were pushing him to capture a vacant job at the local university because, at the same time, his best work, matrix mechanics seemed to be overshadowed.

Heisenberg won the 1932 Nobel Prize in Physics for his development of quantum mechanics based on the principle of 'indeterminacy', sometimes called the 'uncertainty principle', ie, that the position and momentum of any body (or particle) cannot be simultaneously determined: the more precise the determination of one, the less precise os the other.
