Understanding the Space of Rulers and Protractors
1:12:25 - 1:21:34 (09:09)
The space of all rulers and protractors can possibly come very close to having rulers and protractors on it, making it a 14-dimensional world according to Einstein. Einstein claimed that rulers and protractors are crucial in measuring length and angle in the world and not just the four degrees of freedom.

The concept of a 14 dimensional world, which includes the original four dimensions plus extra gadgetry for measurement, is discussed, and the technical debt that arises from trying to explain it is examined.

Summary
Dirac discovered a hidden space of spinners when he found a weird principle by taking the square root of the Klein-Gorton equation. This space of spinners was found within the space of all rulers and protractors and defines a new way of thinking about things like length and angle on a manifold.
