I first wanted to say fire, even though it's a cliche, but then I thought that in antiquity we used like everything without anything that would qualify today as understanding. Also now we have a lot of stuff that we "know" it works based on complicated numerical simulation.

I think the most "understanding" we ever had was in the 40s-50s designing nuclear bombs with slide rules. It was the culture that produced the idea of psychohistory.

Reminder that we have no idea how anesthesia works.
