    It is NOT a standard mathematics (or physics) symbol but is used on the internet when you aren't able to write superscripts.

    The ^ notation for exponentiation came out of BASIC. FORTRAN uses ** for the same purpose, but most other high-level programming languages that I know of don't have a corresponding operator.
