Can you guess where we visited today?
Here are the usual hints:
1. Something profound happened here on Christmas Day, 1642.
2. This event would eventually change science—known back then as "philosophy"— forever.
3. It also changed maths—specifically, the theory of fluxions—and really pissed off a guy named Gottfried.
4. There's an apple tree in the garden there. Click below to see one of the most famous apple trees in the world.
5. But first, if you read Neal Stephenson's trilogy The Baroque Cycle you'll know exactly where this is, and why there is graffiti on the walls of the house.
