A famous picture shows Donald Bradman (Australian cricket legend) meating Babe Ruth (American baseball legend), but did they actually know who each other were? If so, what did they think of each other, and more importantly, what did they think of each other's sports?

This list should include dates and by whom they were signed (the key players on both sides) - I sure hope this exists somewhere!

How are country borders decided to begin with and how are they enforced? What events decides/decided how large a country is/was? Also, I a friend was talking me about Mittelafrika and he said that some African borders were simply determined by colonizers and that's a reason why there are so many civil wars in Africa. Can fellow historians of reddit elaborate on the matter?

Specifically, was the filioque introduced to the island by Norman priests / bishops?

Obviously, not everyone thinks tall men are attractive, but there's a general cultural understanding that height is a preferred feature.

I'm wondering because as China becomes richer and more prestigious in the global consciousness, being shorter -- Chinese people are, on average, shorter than Europeans -- could become a more attractive quality.

Of course, some of the relative shortness of Chinese people is due to nutritional differences, but a substantial portion is genetic.

Why was it unpopular?

Many Islamic scholars were racist. A quick Google search can bring up dozens of quotations that are almost reminiscent of 19th century eugenics. The 14th century Moroccan writer Ibn Battuta said that "Of the neighbors of the Bujja, Maqdisi had heard that "there is no marriage among them; the child does not know his father, and they eat people -- but God knows best. As for the Zanj, they are people of black color, flat noses, kinky hair, and little understanding or intelligence.", while 10th century Persian historian Mohammed ibn Jarir al-Tabari claimed that "Noah prayed that the prophets and apostles would be descended from Shem and kings would be from Japheth. He prayed that the African’s color would change so that their descendants would be slaves to the Arabs and Turks.".

Did this racist rhetoric, along with the institutional enslavement of Sub-saharan African peoples by medieval Muslims, have an affect on the transatlantic slave trade and later attitudes towards Black people?

Similarly, these Muslim writers saw Africans as a distinct group different from them. But did they view themselves and Europeans together as "white", or did that concept not exist?

Was it a wildly successful advertising campaign? A method to differentiate a brand?

Specifically, how did the percentage of unsolved murders compare in 1800 vs 1850 vs 1900 vs 1950?

There is a general conception that because of advancements in forensic science, murders have become easier to prosecute/solve because of DNA evidence, fingerprinting etc. However, is this generally true?

Thanks!

Did they live like the nobility (i.e. lavish homes, servants, the like) or did they have more modest lifestyles? How did they dress? What sort of professions did they have?

For example, the most plentiful calibers today are 5.56, 9mm, and 7.62 if I'm not mistaken.

Now I fail to see how an extra .06mm and a .12mm make an extra difference on the round, and I wonder why the inventors didn't simply go with 5.5mm or 7.5mms. The 9mm I can understand, but I wonder why that one gained popularity instead of the 10mm.

And its not just those calibers, .44s, 38s, 22s, etc etc are all popular rounds, with the 45 and the 50cal really being the only "round numbers" I can think of off the top of my head. Obviously when you get into larger weapons like the 40mm, 6-pounder, etc, you get into round numbers, but in the land of small arms, those small, particular numbers seen to have won the market over. Is there any reason for this?

Rather than minute details I am looking for something that would give me wide coverage about all the reform movements. If possible please post few links of material available on the net for free.

What was so appealing about it (especially to gentiles)? Did it replace something similar in Roman society? If so, why? If not, what changed?
