Some scientists tend to stick to the mathematical formalism of quantum mechanics. According to Feynman Uncertainty Principle is of great significance in quantum mechanics. Without this principle, the quantum mechanics will just collapse. The uncertainty principle "protects" quantum mechanics. The behavior of a quantum system is not independent of its environment. It behaves in a certain way because of the influence of the environment in which quantum system exists. Any act of measurement to determine the properties of a quantum system will lead to interaction between the device and a quantum system. This interaction changes the properties of a quantum system in a way that it becomes impossible to predict the exact behavior of the quantum system. Louis De Broglie's hypothesis that there are waves associated with material particles was confirmed experimentally by Clinton Davisson and Lester Germer in 1927.
