The story of a person going back in time, bringing with them material from the future is one that dates back at least as far as 1838. Sometimes, the character brings a boomstick. Other times, they bring nothing but their clothes.
I want to send a character back in time with a single book. What I want to know is, what is the most revolutionary material they could deliver?
I want to send an Israeli technical professional (doctor, researcher, economist, political scientist, etc) fluent in English, Arabic, and Hebrew to Jerusalem in 30 BCE.
He can bring a single book the size of a college textbook (8.2' x 1.4' x 10.2' or so if you need a starting point) or smaller written in modern English, Hebrew, or Greek. This book does not need to actually exist, but it needs to be something that could reasonably exist.
When I say revolutionary, I mean it in the sense of advancement. An optimally revolutionary book would quickly and easily allow the reader to advance the understanding of the ancient world to modern levels. A poorly revolutionary book would advance the knowledge by only a few years (30 BCE technology improved to 20 BCE tech) or not at all. This can mean advancements in the organization of labor, improvements to metalurgy or farming techniques, or even new political ideas.
If I had to make a guess, it would be Auerbach's Wilderness Medicine or a textbook on the history of mechanical engineering.
Any suggestions or critiques of the question are welcome.
