Invented by Dirac in creating his relativistic quantum theory of the electron, spinors are important in quantum theory, relativity, nuclear physics, atomic and molecular physics, and condensed matter physics. Essentially, they are the mathematical entities that correspond to electrons in the same way that ordinary wave functions correspond to classical particles (including photons). Because of their relations to the rotation group SO(n) and the unitary group SU(n), the discussion should be of interest to applied mathematicians as well as physicists.

"...I think that the book can be very useful for a first course on the subject since it is well written, with many examples and a very good collection of solved problems."
--Mathematical Reviews
"...recommended as a pedagogically sound starting point for anyone wishing to understand what spinors are about, and why they are of importance to physicists."
