What do you mean by Heisenberg's uncertainty principle?

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.

Simply so, what is the Uncertainty Principle?

In quantum mechanics, the uncertainty principle (also known as Heisenberg's uncertainty principle) is any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle, known as complementary variables, such as position x and

What is the definition of Heisenberg Uncertainty Principle?

The Heisenberg uncertainty principle states that it is impossible to know simultaneously the exact position and momentum of a particle. That is, the more exactly the position is determined, the less known the momentum, and vice versa.

Why is the uncertainty principle important?

The Heisenberg uncertainty principle is a physical law that forms part of quantum mechanics. It says that the more precisely you measure the position of a particle, the less precisely you can know it's motion (momentum or velocity). It may not be easy to understand this principle, but it is even harder to explain it.
