Your first day of university. You were sat, wide eyed ready to learn while your classmates chatted and waited for your professor.

You had gotten there really early, so you had been there for a while. As soon as the time hit the hour, your professor walked in.

Everyone fell silent. "Welcome to your first day, I'm Professor Ricciardo. Now I hope you haven't all come here thinking that this is going to be easy. Quantum physics isn't easy and we will soon sort the wheat from the chaff."

"Now open your textbooks to page one and we will begin." He said, switching on the projector onto the whiteboard. You already knew that this was the right place for you.
