Related to Weyl spinor: Dirac spinor, Majorana spinor


A mathematical object associated with group representations, often used in theoretical physics to model certain topological properties of space. Spinors resemble vectors but change sign (that is, they are multiplied by -1) when rotated 360 degrees.

[spin + -or (on the model of tensor vector).]
