I’m no professor of natural sciences or anything, but that’s not really the point. I think everyone will have different answers, and it’s a hell of a fun icebreaker.
My guesses are below. Let me know your thoughts in the comments!
1. Language and the written word
2. Math and science (incl. space travel)
3. Health and medicine
4. Law and politics
5. Ethics and philosophy
6. The arts
8. Trade and economics
9. The steam engine
10. The computer
