The more I dive into the history of various technologies (and even professions), the more it becomes apparent that militaries are responsible for a vast proportion of historical advancements, even in the most unexpected areas. Edit: Also responsible for a vast supply of historical datasets. Edit 2: IMHO, the most fascinating is all the tie-ins between artillery, spycraft, astronomy, aerospace/rockets, geodosy & cartography (and invention of the chronograph), tidal monitoring & weather keeping, nuclear weapons, gps, and probably a dozen more topics I'm forgetting off the top of my head. Individually, each of these is a mammoth of a topic on its own. But the interplay in their development (as influenced by big-picture military strategy) is just mind-boggling to me. It is by far, the most interesting, persistent, and deep rabbit-hole I've encountered. (Hint: Ballistic missiles are essentially long range artillery. Hint 2: They require gravitational variation to be taken into account for targeting.)
