The many faces of projective objects

In mathematics and physics, there is quite a long list of objects which are, in some way, related to each other. It can be useful to keep down a little list of those various types of objects and their relationships.

Projective space

Probably the oldest such objects are the ones related to projective geometry.

Plücker coordinates

Quaternions

Quaternions are defined as an algebra over a $4$-dimensional vector space

Differential forms

Grassmann algebras

Spinors

Twistors
