Paragraph: One of the most amazing principle in modern physics is the Heisenberg uncertainty principle. According to it. It is not possible to make a simultaneous determination of the position and the momentum of a particle with unlimited precision. The same is applicable for energy and time coordinate of a particle. P x = h 2 = E t . where : P = uncertainty in momentum; x = uncertainty in position; t = uncertainty i
