Umm, I'm not sure how you could learn QED without encountering a clifford algebra. That's essentially the defining relation of spinor fields (fermions), i.e. they carry a representation of the clifford algebra: \{ \psi^\mu, \psi^\nu \} = \eta^{\mu\nu} Kris, who learned QED from a not very enlightened professor. --z6Eq5LdranGa6ru8 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE6e/STWry0BWjoQKURAkloAJ9C3aW5md5KR30Q9WWbThmNClU8/wCfWreF qRnPHbZ96YdBFpirZ5aNDVI= =8vlL -----END PGP SIGNATURE----- --z6Eq5LdranGa6ru8-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
