My first physics paper, of no interest whatsoever today.
The electron magnetic moment calculation was implemented by entering integrands on IBM punch cards, flying on a 4-person plane to Brookhaven with boxfulls of cards, and feeding batch jobs into the CDC computer there.
We had no computer, but Cornell Synchroton had several state-of-the-art DEC PDP-10s, so advanced that they had keyboards and screen terminals attached. I was allowed to use them after 1AM, only to edit, but absolutely not compute. So I wrote an symbolic algebra language for evaluation of Dirac gamma-matrix traces entirely as macros in TECO, the DEC text editor. Every time they checked on me, I was in editor mode, so they never caught me.
