Math, physics, and computer science
Godel, measurement, astronomy, infinities, and ideas that change the scale of the room.
Godel's Incompleteness Theorems
Godel showed a precise kind of trouble: some true arithmetic statements can be stated inside a rulebook but not proved by that rulebook.
How Did They Measure The Moon?
How shadows, eclipses, and a half-degree angle helped people measure the Moon from Earth.
Computer Science As Art
Artists and curious people can find a different kind of beauty in algorithms, proofs, compilers, distributed systems, and type systems.
