I have done astrophysics research, and intend on doing engineering in the future.
Why do you ask?
I ask for a plethora of reasons.
1. I'm nosy
2. I think knowing the science backgrounds of the people on this forum would be pretty cool, and particularly the ratio of AnCap hard scientists to soft sciences would be pretty cool.
3. Eventually I would like to see just what fields AnCaps currently work in. or find interesting.
