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
Canonical commutation rule for position q and momentum p variables of a particle, 1927. pq − qp = h/(2πi). Uncertainty principle of Heisenberg, 1927.
German physicist Werner Heisenberg (1901–1976), who introduced Uncertainty Principle in 1927

In Newtonian mechanics, momentum is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction. If m is an object's mass and v is its velocity,
Uncertainty principle
…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. In other words, the more accurately one property is measured, the less accurately the other property can be known. More…
