Tensors
Scalars, vectors and matrices are tensors.
Some new words are needed to generalize their properties.
- Simple tensors.
- Covariant versus contravariant.
- Going from covariant to contravariant.
- Einstein's summation convention.
- Symmetric and antisymmetric tensors.
- Derivatives in flat spacetime.
- Covariant derivatives in curved spacetime.
