With classical physics, we are certain that we can determine the future by analyzing the data from the past and the present. However, the discovery of quantum mechanics shown that even with all necessary information, the future remains unknown.

In the early 1900, four important events had revolutionized science and the way we think about the world around us. They are Planck’s solution to the blackbody radiation, Einstein’s explanation of the photoelectric effect, the Bohr model of the atom, and the de Broglie wavelength of material particles
