When I was younger, I would invent a game for myself involving a time machine. The rules were these: you were given a time machine, and you could set it to go back to just a single place and time in the history of the Earth, and stay there for 24 hours. You would then be returned to the present. You would be allowed one notebook and pencils, but no cameras, video or otherwise, or recording devices.
And you could do this for two reasons: to answer as many scientific questions as you could by being in one place and time (you were allowed to bring your notebook back), or to simply satisfy your own curiosity.
There was one more provision: you could also specify to be set down in a single area where there were specific things you wanted to see, like a band of Neanderthals or a T. rex, for of course you wouldn’t know where or when you could see them in advance.
I never resolved this question for myself, even to the extent of seeing whether I wanted to answer scientific questions or just see what a T. rex really looked like.
I’m asking readers here (and I hope I’ve been sufficiently specific) this question: where would you want to be taken for 24 hours in your time machine? Please state your reasons, too.
