The Quantum Realm

The universe is made out of tiny little particles, but you don't often think about it. What tiny really means? Yeah, we do this a lot when we think about the quantum realm. We try to sort of use the ideas we have from our everyday experience and apply them to particles. Apply them to these tiny little bits so that we can make sense of them. But how well does that really work? Is it really relevant? Or is the quantum realm just totally alien?"
