Erwin Schrödinger is known as the father of quantum mechanics— which parts ways with classical mechanics at the atomic and subatomic level. Rather than following the usual (and logical) Newtonian laws, quantum mechanics posits some unique theories—some of which are outlined in these videos.
So, what does this mean to us? Aside from seeking to explain how our world works, quantum mechanics is being used by some individuals looking to create quantum computers. Traditional computing is based upon binary code where bits can be either a 1 or 0. In quantum computing, a Qubit can be a 1 or 0 or 1 and 0 at the same time. If this turns out to be true, then quantum computers can run calculations much faster than traditional computers.
