History Werner Heisenberg

History Werner Heisenberg formulated the uncertainty principle at Niels Bohr's institute in Copenhagen, while working on the mathematical foundations of quantum mechanics.

the German physicist Werner Heisenberg

In 1927, the German physicist Werner Heisenberg introduced the 'Uncertainty Principle', according to which the act of measuring the physical properties of a particle alters its behaviour; that is, locating it in a small region of space makes the momentum of the particle uncertain, whereas measuring precisely precisely its momentum's momentum makes the position uncertain (Heisenberg, 1927).

developed by W. Heisenberg

The uncertainty principle, developed by W. Heisenberg, is a statement of the effects of wave-particle duality on the properties of subatomic objects.

In 1927 German theoretical physicist Werner Heisenberg developed the Uncertainty principle.

formulated by 20th-century physicist Werner Heisenberg

The “uncertainty principle” formulated by 20th-century physicist Werner Heisenberg sets a limit on the shortest possible duration of a light pulse of any given wavelength in terms of time or number of cycles.

Werner Heisenberg , one of the pioneers of quantum mechanics,

Werner Heisenberg, one of the pioneers of quantum mechanics, introduced the uncertainty principle, which states that we cannot measure the exact position and velocity of a particle at the same time.
