And I'd also be interested in the same thing for any other pre-1900s time period.

I have been doing some reading on the space race, and I have found myself to be very interested in the effects it had on the the U.S and the USSR. I am particularly interested in the economical aspect, especially since I can find very few credible source concerning the USSR. So in what way did it effect the countries? Was the expenses one of the main reasons for the downfall of the USSR?

I know the question is formulated in a somewhat clumsy matter, but I really have no idea how to do it better. The question is a result of me reading that girls in the olden days would get married at a very young age only if they were from a powerful family who had alliances and businesses to attend to, and marriage was a way of solidifying these. Ordinary people would allegedly get married at an age roughly similar to what we see today. How much truth is there in this statement and how did these trends change over time?

I would like a little bit of an explanation of how the Mk-39 hydrogen bomb ended up buried about 185 feet in the soil (as I was told) of Goldsboro NC.

I know that he is considered by some to be the father of forensic medicine but are there specific cases? Any book recommendations would be appreciated.

You know, because they seem to have devolved into a Deletationship by now. How'd that come about?

Imperial Japan's atrocities and brutality in Mainland China, Korea, Philippines, etc seem completely different to the way they operated in Taiwan during their rule there. What was different about Taiwan?

For example, as Napoleon conquered half of Europe, did he or anyone at that time discuss the fact that these events would enter the annals of history? If so, how far back can we go to see the same trend? Would thinkers contemporaneous with Alexander the Great have regarded his conquests as likely historically significant?

Essentially, what I'm asking is: for how long have entities - be them individuals, groups of people, businesses, states, etc. - or their peers been conscious of their potential impacts on history?

Did they use hours/minutes/seconds, etc? If not, when did these modern measurements come into usage?

On the side of the Communists?

How accurate is Battlefield 1, the World War One game made by Dice Entertainment? It seems really accurate. I am really interested in World War 1 now. What sources should I go to to learn about it?
