Werner Karl Heisenberg (; German pronunciation: [ˈvɛɐ̯nɐ ˈhaɪzn̩ˌbɛɐ̯k] (listen); 5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, this matrix formulation of quantum mechanics was substantially elaborated. He is known for the uncertainty principle, which he published in 1927. Heisenberg was awarded the 1932 Nobel Prize in Physics "for the creation of quantum mechanics".Heisenberg also made important contributions to the theories of the hydrodynamics of turbulent flows, the atomic nucleus, ferromagnetism, cosmic rays, and subatomic particles. He was a principal scientist in the German nuclear weapons program during World War II. He was also instrumental in planning the first West German nuclear reactor at Karlsruhe, together with a research reactor in Munich, in 1957.
Following World War II, he was appointed director of the Kaiser Wilhelm Institute for Physics, which soon thereafter was renamed the Max Planck Institute for Physics. He was director of the institute until it was moved to Munich in 1958. He then became director of the Max Planck Institute for Physics and Astrophysics from 1960 to 1970.
Heisenberg was also president of the German Research Council, chairman of the Commission for Atomic Physics, chairman of the Nuclear Physics Working Group, and president of the Alexander von Humboldt Foundation.
The Heisenberg Uncertainty Principle states that both the exact (as near as we can get to thusfar) position AND momentum of a particle cannot be obtained because in learning its exact position we alter its momentum and vice versa. Does this mean we only have rough measurements of particles...
Heisenberg Uncertainty Principle - h/(4.Pi) versus h/(2.Pi)
What's the reason behind the factor 2 in the way some books/papers present Heisenberg Uncertainty Principle?
h/(4.Pi) versus h/(2.Pi)
When in history did this discrepancy arise and who was responsible for that?
Ultimately, which...
Recently I had a discussion with friends about impact of H.U.P. on some biological functions.
We had disagreement, about uncertainty of position of ion, say in neuron connected to another one by synapse, as a consequence of HUP, point was that if there is some uncertainty in position of ion or...
How does one work in the Heisenberg picture? Can you dequantize and solve the classical Hamilton's equations and somehow requantize this classical solution for the time evolution of the position and momentum operators (and more importantly the eigenvectors)? How would one go about doing that...
Hello this is my first post.
I am a 15 year old 10th grade student in a philosophy program and now we are studying the famous Greek philosophers.
I have a problem that was asked by a teacher that I would like to answer. And although I have tried I have not come up with an answer on my own...
I have been reading that the quantity called "Weyl curvature" can exist independently of any matter, or energy, in the universe? :confused:
This seems to contradict Heisenberg uncertainty which says there can be no 100% vacuum, because uncertainty in position and uncertainty in momentum...
At which scale in length terms does the Heisenburg Uncertainty Principle kick in for Stringtheory?
In the string vibration for Gravitational interactions, as the scale is condensed, surely this would have a 'bigger' Uncertainty in strings that split off due to their proximity in scale...
