Heisenberg Uncertainty Principle: Due to the dual nature of matter and radiation, it is impossible in case of small particles such as electrons to determine simultaneously both position and velocity (or momentum) with absolute accuracy. This fact was first noted by Werner Heisenberg’s in 1927 and he proposed a principle known as Heisenberg’s Uncertainty Principle which states that “it is impossible to measure at any given moment both the position and momentum (or velocity) of small particles in motion with the desired accuracy” i..e. there is always uncertainty in the simultaneous determination of both position and momentum.
