The Heisenberg Uncertainty Principle.
The Heisenberg uncertainty principle is represented mathematically as deltax × m*deltav = h/2, where deltax is the uncertainty in the position, deltav is the uncertainty in the velocity and h is Planck's constant divided by 2. Would it be possible to develop an instrument that could determine both the position and velocity (momentum) of an atom or subatomic particle such as an electron and thus negate the uncertainty principle? Fully explain your answer.
