Question

Heisenberg uncertainty principle?​

Answer 1

Answer:

Uncertainty principle, also called Heisenberg uncertainty principle or indeterminacy principle, statement, articulated (1927) by the German physicist Werner Heisenberg, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory.

Answer 2

Heisenberg uncertainty principle---

The Heisenberg uncertainty principle states that the more precisely determined one of two properties, position and momentum, of a particle is, the less precisely determined is the other. This results from the wave-matter nature of particles and is independent of who is observing the momentum or position and so this principle can't be overridden by improvements in technology. This is in contrast to the similar observer effect, which states that in affecting the observation of a particle, say by bombarding an electron using gamma-rays, you are changing its momentum, and therefore the observer cannot obtain accurate knowledge of both at any one time.

The uncertainty principle is also in sharp contrast to classical wave mechanics, which says that precise simultaneous values can be assigned to different physical quantities.
