We generally think of the quantum world as something completely separate from the world we see and interact with. I guess you, in a manner of speaking, you could say that this line of thinking isn't far from the truth, but, in fact, they are the same world.. just with drastically different rules.
With that said, if you open your mind to it, there is a whole dynamic host of things, quantum things, happening all around you. Sure, many of you have heard of such phenomena: like electron repulsion — a principle that essentially tells us that the electrons in our bodies push against the electrons in everything we come in contact with, and they prevent us from ever truly touching anything — the van der Waals force, which explains how geckos can scale walls, and even the most basic forms of magnetism.
In a new episode of "The Quantum Around You" — a truly exceptional youtube channel launched by the University of New South Wales (UNSW) — Andrea Morello, the Associate Professor of the School of Electrical Engineering and Telecommunications at UNSW, discusses the quantum effects that stem from flipping a light switch.
