Everything You Need to Know about Quantum Physics (Almost)

Quantum mechanics is a mind-bending theory with dead-and-alive cats and particles in two places at once.

What is quantum physics?

Quantum physics is a branch of physics also known as quantum mechanics or quantum theory.

Mechanics is that part of physics concerned with stuff that moves, from cannonballs to tennis balls, cars, rockets, and planets. Quantum mechanics is that part of physics which describes the motions of objects at molecular, atomic, and sub-atomic levels, such as photons and electrons.

Although quantum mechanics is an extraordinarily successful scientific theory, on which much of our modern, tech-obsessed lifestyles depend, it is also completely mad.
