Graduate of a major Australian University, 1999 PhD. Theoretical Physics (High Energy Physics). I love this forum since it helps me remember a lot of stuff since forgotten. Whilst I did do postdoctoral research, this was for a relatively short period of time, and even though I taught Uni Physics on a part-time on-and-off basis for years, my career is Information Technology. Since the pandemic began, I have ample time to read posts on PSE!
