Science Gifts for Birthdays and Christmas! Robots, brains, cells, molecules. A treasure trove for geeks, nerds, and science-lovers.
Steampunk styled machines. This means lots of brass, cogs, and other ornate bits of machinery. A Pythagorean Mathematics Engine (illustrating Pythagoras' Theorem for right-angled triangles) contains stained glass windows whose areas change as cog wheels rotate. In other maths engines, rods attached to rotating wheels trace out sine waves and tangent graphs. A brass eye is inspected by a robotic oculist. Welcome to the glowing clockwork universe where abstract ideas are wrought in metal.
