You Can Take One Modern Non-Fiction Book Back To 1750

Good point, but it would still be my choice. And aren’t we there to help interpret?

The thermodynamics would be solid gold, though physicists would be annoyed to have to learn obtuse math tools like matrices. (In fact, they were annoyed at the time, nearly a century later.)

But frankly, a history of science book might be even more useful. The problem with a textbook is that it presents only the results, without much of the background on how the principles were verified. Of course, you might need to blot out the scientists’ names!

Definitely the chemistry would be difficult. Alchemy wasn’t far gone at that time. The experimental basis for atomic theory wasn’t there and wouldn’t be, for quite a while. While names & atomic weights for elements would be interesting, quite a number of them hadn’t been isolated yet, so folks would wonder what substance the texts would be discussing. How did we even measure atomic weights at first? I shudder to think of how we measured Avogadro’s number (long after Avogadro, alas.)

Is our time travel story accepted? If it is accepted and widespread knowledge that I traveled back through time with a book to hand down to the masses, I might bring a history book that covers 1700 to 2000. Get on the right side of history now, you primitives!

Or is the goal to change history? Maybe bring back a book detailing gunpowder, military tactics, and detailed maps of North America to distribute to all the native people. In 1750 there were only the 13 colonies, right? Could a single book (even if we sat down and wrote it ourselves) turn the tide in favor of Native Americans?

I think your goal is whatever you’d like it to to, whether it’s to get them “on the right side of history” with a copy of Guns, Germs and Steel or get the to invent the bicycle 130 years early with a copy of Let’s Go Mountainbiking!. Actually, the bicycle might be an interesting one.

You say that as if it would be a bad thing!

I think a Chemistry book would be a good choice. I don’t know the book that Pleonast suggested, but a college-level General Chemistry text will contain the history of how things were discovered. Much of it would be extremely difficult for 18th Century scientists to fully grasp, but they weren’t exactly morons. Since the text would cover things that were discovered before and during their time, they would have at least a starting point. They would have to take a lot of it on faith, but they could use the historical information to at least infer the meaning of the things that were then beyond their ability.
