What is produced when a muon decays?
The muon is a lepton which decays to form an electron or positron. The fact that the above decay is a three-particle decay is an example of the conservation of lepton number; there must be one electron neutrino and one muon neutrino or antineutrino in the decay. The lifetime of the muon is 2.20 microseconds.
Why can’t we know the position of an electron?
The Heisenberg uncertainty principle states that the exact position and momentum of an electron cannot be simultaneously determined. This is because electrons simply don’t have a definite position, and direction of motion, at the same time! We know the direction of motion.
Is the Heisenberg uncertainty principle true?
At the foundation of quantum mechanics is the Heisenberg uncertainty principle. Physics students are still taught this measurement-disturbance version of the uncertainty principle in introductory classes, but it turns out that it’s not always true.
Is uncertainty principle disproved by Einstein?
Einstein’s opponents used Heisenberg’s Uncertainty Principle against him, which (among other things) states it is not possible to measure both the position and the momentum of a particle simultaneously to arbitrary accuracy. In 1935, Einstein thought of a way to explain the problems with quantum mechanics.
Did Einstein believe in quantum theory?
Einstein saw Quantum Theory as a means to describe Nature on an atomic level, but he doubted that it upheld “a useful basis for the whole of physics.” He thought that describing reality required firm predictions followed by direct observations.
Can Heisenberg uncertainty principle be violated?
(Phys.org)—If an object traveling through spacetime can loop back in time in a certain way, then its trajectory can allow a pair of its components to be measured with perfect accuracy, violating Heisenberg’s uncertainty principle.
