“In a nice little house in Atro City there lived a man called Doktor Gleichstein. He was a kind of scientist, and he was very good at his job, which is why he always worked from home. He looked a little funny because he kept losing his eyebrows. Quantum Physics, is sort of like ordinary Physics, only you tend to spend a lot more time looking for the cat. He worked in the sitting room because he’d blown the garage up once already. Apparently a lot of things happened by accident in Quantum Physics.”
