Content: While not as essential as the fundamental pillars, it did play a significant role and is known as Heisenberg’s Uncertainty Principle. He reasoned that since the nature of matter is wave-like, some properties, such as the velocity and position of electrons, are complementary to one another. In simpler terms, there is a limit up to which each property of an electron can be simultaneously measured with a degree of accuracy. Heisenberg’s Uncertainty Principle

When a quantum ‘observer’ is watching, Quantum Mechanics states that particles can also behave as waves. This can be true for electrons at the sub-micron level, i.e., at distances measuring less than one micron, or one-thousandth of a millimeter. When behaving as waves, electrons can simultaneously pass through several openings in a barrier and then meet again on the other side. This meeting is known as interference. Now, the most absurd thing about this phenomena is that it can only occur when no one is observing it. Once an observer begins to watch the particles going through the opening, the obtained image changes dramatically:
