So today in my physics class we learned about Tycho's passion for astronomy despite being a member of Danish nobility, and how Kepler stole his data from Tycho's family after his death and used it to come up with his own theories, one of which was elliptical planetary orbits. How exactly did he pull this off? I'd imagine it would be quite hard to steal something from a noble's property. I asked my teacher, and he jokingly responded with "Ocean's 11 style" and moved on. Hoping someone here can enlighten me!

The obvious is that they both suggest the populace can change the ruling system if the ruler does not rule well

When were uniforms first used? What could be seen as a uniform, was a coat of arms good enough or only a scarf of the same colour? How did it evolve and where did it come from?

I know this is a bit of a strange question but the thought just popped into my head.

Particularly why are there almost no stone structures? Is there less stone available, is it lower quality?

if yes, what was their status?

Thanks.

In the times of slavery, how/why was Africa at such a great disadvantage to be so easily taken captive and controlled?

The Romans had the strongest military of the Mediterranean world and were quite capable of dominating the Gauls so what made the Germanic tribes so difficult to pacify? Did the Romans simply not care about expanding east of the Rhine? Or did the tribes have a style of warfare that was particularly effective against the Romans?

As inhumane as they were, was any valuable information that sped up medicine collected from Nazi research?

Perhaps experiments deemed too dangerous to be performed on humans, even in the 21st century.

I am, have been and always was absolutely engrossed by Roman history but this is the one part that I have never been able to wrap my head around.

This battle ended the Final War of the Roman Republic and created the Roman Empire as a result, making it one of the most important events in all of western history to say the least. However, It was always my understanding that Marc Anthony had the advantage over Octavian Caesar. Anthony had more men and certainly more experience than the self proclaimed boy emperor, so why was it that he lost so splendidly?

Could someone inform me as to why most fascists in the inter-war period were so virulently opposed to Communism? I know that, to an extent, they was some opposition in Germany in particular due to the high proportion of Communist thinkers who were Jewish, but other than that, I can't fathom why they would be so opposed to it.

I'm aiming this more at the Medieval and renaissance era's, but would be interested in knowing the answer in broader senses. I enjoy reading a lot of Phillipa Gregory novels and they make it seem like consummation on the wedding night was a big deal. Everything I've read both in Gregory's novels and other books would say that sex with a menstruating woman was considered a horrible sin. As she was unclean at the time. It also seems that women didn't talk much about their cycles, so my first guess is when her cycles were wouldn't be discussed to avoid lining the dates up to not fall on her menses.

So how would they avoid an embarrassing wedding night where the bride and groom can't consummate the marriage?
