    Undergrad Looking for a paper about spinors

    Thanks Paul Colby. I already have what you suggested but my interest is partly historical. I am interested in some early papers which contributed to the the theory of spinors.

    Undergrad Looking for a paper about spinors

    I am looking for a scan of the paper 'An Introduction to Spinors' by Bade & Jehle. Any help? Thanks.

    Undergrad Matrix representation of rank-2 spinors

    Assume that all spinors are 2-component ones. If spinor mAB = nAkB, what are the matrices representing spinors mAB and mBA?

    Does memory follow classical or quantum methods?

    In my daily routine, I read several short extracts. The same extracts, every day, every year, so that I can now repeat them by heart. I make no effort to remember anything. I just let words flow out...

    Graduate Dirac's 1958 lecture on spinors

    Are there any sources for the set of Dirac’s Cambridge lectures in early 1958, which had a huge and very specific impact on Penrose’s thinking about 2-component spinors? Thanks.

    Undergrad Dirac's 1972 Boston talk on Projective geometry in quantum mechanics

    I am reading the transcript of the talk in the pdf mentioned above. A few days ago I found online a copy of handwritten notes (by the great Dirac himself or perhaps by Hart) where there were some diagrams mentioned in the transcript. But unfortunately I did not save these handwritten notes! I...

    How to obtain these equations in 'Spinors in Physics' by J Hladik?

    Now I notice that the, apparently arbitrary, choice in 1.1.12 was made as a preparation for 1.1.24.
