To justify the claim, Jungk had printed an excerpt from a personal letter from Heisenberg. The excerpt, however, was taken heavily out of context, and in the full letter Heisenberg was far more demure about whether he had taken a strong moral stance.
After reading the excerpt, Bohr was understandably flustered that Heisenberg was apparently claiming to have purposely derailed the Nazi bomb project, as it did not match his own perception of Heisenberg's war work at all. Some historians of science have taken the Bohr's draft letters as evidence against Heisenberg's contention that he had met with Bohr to signal that Germany's scientists would not pursue the development of nuclear weapons. Others have argued that Bohr profoundly misunderstood Heisenberg's intentions at the meeting, and that his reaction to Jungk's work was overly passionate.
Significantly, Bohr's draft letters confirm virtually all of Heisenberg's recollection to Jungk of the substance of the meeting. However, as a piece of evidence the letters cannot provide an answer to the question of why Heisenberg broached the topic of nuclear weapons -- but not their technical aspects —with Bohr, or whether Bohr formed the correct "impression" of what Heisenberg wanted to say.
Allied intelligence through Stockholm continued to sound the alarm about Nazi uranium research right up to war's end, but this was part of Diebner's project, not Heisenberg's. According to an apocryphal story, Heisenberg was asked what he would ask God, given the opportunity.
And why turbulence? I really believe he will have an answer for the first. This story is probably untrue, as it bears an uncanny likeness to the following reported incident: the difficulty of explaining and studying turbulence in fluids was wittily expressed in by the British physicist Horace Lamb, who, in an address to the British Association for the Advancement of Science, reportedly said, "I am an old man now, and when I die and go to heaven there are two matters on which I hope for enlightenment.
One is quantum electrodynamics, and the other is the turbulent motion of fluids. And about the former I am rather optimistic. Werner Heisenberg. Werner Heisenberg books and biography.

Biography Philosophical problems concerning what it means to know something about the world have always been of interest to many scientists, but philosophy underwent an unexpected twist with the advent of what we now call the uncertainty principle or the Heisenberg uncertainty principle, after its discoverer. A brilliant physicist, Werner Heisenberg had made discoveries by the age os 24 that would garner him a Nobel Prize a few years later in , namely, a way of formulating quantum mechanics using the then-new branch of mathematics called matrix algebra.
In , he formulated a quantum mechanical indeterminacy or uncertainty principle, which concerns how accurately certain properties of subatomic particles can be measured. Earlier physical theories had held that the accuracy of such measurements was limited only by the accuracy of available instruments.
Heisenberg overturned this notion by demonstrating that no matter how accurate the instruments, the quantum mechanical nature of the universe itself prevents us from having complete knowledge of every measurable property of a physical system simultaneously. For example, the more precise our knowledge of a subatomic particle's position, the less precise our knowledge of its momentum; more profoundly, the particle does not merely have a momentum that we simply cannot accurately measure, but literally does not have a determinate momentum.
In early , he and Pauli submitted the first of two papers laying the foundation for relativistic quantum field theory. But Heisenberg fought back with an editorial and a letter to Himmler and the matter was eventually resolved. Heisenberg met Elisabeth Schumacher at a private music recital in he enjoyed classical music and was himself an accomplished pianist and the two were married soon after.
They were to bear twins, Maria and Wolfgang, in , followed by five more children over the next 12 years: Barbara, Christine, Jochen, Martin and Verena. In , he was asked by the Nazi administration to direct the Uranium Club's research more toward developing nuclear weapons and, when Heisenberg prevaricated, the authority and regulation of the project was changed. But, as Allied bombing increased in Berlin, he moved his family to their rural retreat in Urfeld, and later joined them there.
In May , at the end of the War, Heisenberg was picked up by Operation Alsos along with nine other prominent German scientists working in the nuclear field and was incarcerated for a time in England under Operation Epsilon.
Throughout this period, he continued to lecture across the world and to publish papers, including works on superconductivity, turbulence and cosmic-ray showers, as well as being appointed to various councils, commissions and associations, and receiving numerous honours and awards. Werner Heisenberg was a German theoretical physicist and Nobel Prize winner. Scientific Contributions Heisenberg is best known for his uncertainty principle and theory of quantum mechanics, which he published at the age of twenty-three in Load more.
