Quantum Mechanics

Quantum Mechanics (QM) is even more unsettling than relativity for one reason, it goes against our preconceived notions of everything. QM redefines what matter is, instead of being the tangible stuff we're used to matter becomes a probability. It is important to note here that in everyday circumstances this viewpoint doesn't really matter, but in circumstances where the objects and distances are incredibly small QM plays a huge role. So until you observe a particle it occupies what is known as a probability wave, where it can be anywhere, but upon observing the particle it becomes solid, that is it occupies a certain amount of space and has a certain velocity. However, as will be discussed next time this space and velocity will always have a certain amount of fuzziness associated with them.
