Let's say you have to travel back in time and make the biggest impact with your scientific knowledge. To which time period would you travel and what would you do?
Keep in mind you can't just expect people to believe you and listen to you. So no bullshit like telling Hitler how to build a nuke.
Some more food for thought:
- You might be infinitely smarter than a cave man, but knowing how to make steel or rotate crops will not help you archive much on you own.
- You won't be able to impress anyone with your knowledge of advanced math or laws of physics if you can't prove them and defend against actual smart people of their time.
