## Clifford Algebra formalism

Hestenes’ school.

- Cavendish laboratory’s introduction
- Hestene’s most famous bit of rhetoric
- Hestene’s most infamous bit of rhetoric
- stack exchange arguments.

Alan Bromborsky, An introduction to Geometric Algebra and Calculus

Alan Macdonald, Geometric Algebra:

Geometric algebra and its extension to geometric calculus unify, simplify, and generalize vast areas of mathematics that involve geometric ideas, including linear algebra, multivariable calculus, real analysis, complex analysis, and euclidean, noneuclidean, and projective geometry. They provide a unified mathematical language for physics (classical and quantum mechanics, electrodynamics, relativity), the geometrical aspects of computer science (e.g., graphics, robotics, computer vision), and engineering.

## Differential forms formalism

- Flanders, Differential forms
- Frankel, the geometry of physics
- Bachman’s book (Bach03) seems popular and is free.
- John Baez’s high speed introduction

## How is tensor?

Multilinear weirdness.
