History How would you survive and prosper if sent back in time with no possessions?
I was thinking along these lines too, but on the other hand maybe you could pick a critical point in history and dedicate yourself to changing it. Something that knowledge of the future could really act as an inflection point for. Presumably whatever it is, also requires that people not...- dvdt

This is exactly the...- dvdt

Other Resources for special relativity background before Gravitation
I see, that's a good point. In terms of mathematics I've only been formally taught through what was called "Pre-calculus". Beyond that I know what I either learned in school in classes that were frankly unrelated to STR/GTR, and what I've pieced together over years of reading books like Prime...- dvdt

Other Resources for special relativity background before Gravitation
I've just reached the opening in chapter 2 wherein there's a brief discussion of concepts and math which should be familiar to the reader (Basic SR stuff it seems), and I'm not familiar with it unfortunately. I am familiar with future and past light cones, and the language of causality, but not...- dvdt
