Heisenberg's uncertain legacy

Collections of essays often have an uncertain status. In the absence of any overarching message, they stand or fall on the quality of the writing and the author’s ability to offer regular jolts of insight and entertainment. When (full disclosure) David Kaiser told me last summer that he was putting the finishing touches to his anthology Quantum Legacies: Dispatches from an Uncertain World, I had little doubt that it would meet the challenge.

Werner Heisenberg has a lot to answer for. As one of the founders of quantum mechanics, he left a huge legacy to physics. As the inventor of the uncertainty principle, he also left a huge legacy outside physics. Albert Einstein may be more widely recognized by the public – and his theory of relativity often appears in popular culture – but it is Heisenberg who has had the greater impact on public discourse.

Heisenberg uncertainly principle can be discussed by using the pattern classification technique of Artificial Neutral Networks with Back propagation learning rue. In this process a suitable arrangement can be constructed that contains the control of two experiments, one of which is designed to measure the position and other one is designed to measure the momentum of a sub-atomic particle (the electron). The Control system will determine either the position of momentum of electron, which less uncertain for any wavelength of light at any instant and start measuring the less uncertain quantity with the corresponding experiment.
