H is the Plancks. D r the second element is associated with the uncertainty in velocity. In a single statement Heisenbergs Uncertainty Principle points out that both the position and momentum of a particle cannot be known at the same time.
So how do we mathematically define this principle.
H is the Plancks. It tells us that there is a fuzziness in nature a fundamental limit to what we can know about. In Heisenbergs principle it is stated that the product of the range of possible positions D x and the range of possible momenta D p x is greater than or equal to some number. What it basically refers to is the fundamental incoherence of quantum particles.
