The uncertainty principle, also known as Heisenberg's indeterminacy principle, is a fundamental concept in quantum mechanics. It states that there is a limit to the precision with which certain pairs of physical properties, such as position and momentum , can be simultaneously known.
Learn the definition, formula and application of Heisenberg's uncertainty principle, which states that it is impossible to measure both position and momentum of a particle simultaneously. Explore the examples, numerical problems and the origin of the principle based on wave-particle duality.
Learn about the uncertainty principle, a fundamental concept in quantum mechanics that limits the precision of measuring position and velocity of a particle. Explore the mathematical formula, the wave-particle duality, and the applications of the principle in physics and chemistry.

Sep 12, 2022 · Heisenberg’s uncertainty principle is a key principle in quantum mechanics. Very roughly, it states that if we know everything about where a particle is located (the uncertainty of position is small), we know nothing about its momentum (the uncertainty of momentum is large), and vice versa.
Oct 8, 2001 · If one feels that statements about inaccuracy of measurement, or the possibility of simultaneous measurements, belong to any satisfactory formulation of the uncertainty principle, one will need to look for other formulations of the uncertainty principle.
