What is Quantum Physics?

Contrary to the theory of relativity, quantum physics (also called quantum mechanics) is specific to the laws of the microscopic realm of the elementary particles of matter. It is a collection of laws that govern how the universe is made up. Some of the greatest minds have dedicated their lives to the advancement of this intricate theory.

One such scholar is Werner Heisenberg. He proposed that it is impossible to measure all of the quantum properties of an electron at once with his “uncertainty principle”. This principle holds true because to determine the position of an electron, one must emit light through an object and onto a light detector. However, the light emitted always changes an electrons velocity to some extent. This effect on the velocity can be reduced by lowering the intensity of the light that is used to measure the electron’s properties, yet this also decreases the accuracy of the measurements. In turn, it is not possible to accurately measure every property of an electron.
