EVEN YOU can understand what this fundamental equation of Physics actually means!

Hey you lot, how's it going? I'm back with another Physics video. This time, we're discussing the Schrödinger Equation (yes that's right, Schrödinger of dead/alive cat fame). This equation is the cornerstone of Quantum Physics, also known as Quantum Mechanics. However, it looks like a very complicated equation - so in this video I'll break it down for you. By the time you've finished the video, you'll be an expert in Quantum Physics (disclaimer: probably not lol, but you'll at least know a bit about what's going on).

So what is Quantum Mechanics exactly? Well, it's a theory that serves to describe how the universe works on a very small scale (think atoms, and smaller). At this scale, objects behave very differently to how they do at the scales we're used to. This get extremely weird, and students of Quantum Mechanics are often heard asking "HOW CAN THIS EVEN BE POSSIBLE?!" Unfortunately, nobody knows. However, at least until now, there isn't a single piece of experimental evidence that goes against Quantum Mechanics! If there was, we could reject this weird theory and move on with our lives (or at least modify the theory). But we can't...

The Schrödinger Equation then, explains what happens to what's known as a "quantum state". It describes the behaviour over time of this quantum state, which has to evolve in a very particular way based on the total energy of the state. A full description is in the video - so stop reading this description :D
