With all of the documentaries and everything that is available online, it is so easy to get diagrams and in depth explanations of how a nuclear bomb is built.

But I know for a long time and even today, countries don't have "nuclear technology".

If it's so easily available online, why is that?

For example, I know Russia never wanted to give China nuclear tech during the Cold War, what was preventing them from finding it online and engineering through there?

And countries like N. Korea, why is it so hard (until recently) to build a stable nuclear weapon?

Ptolemy 1 became the Pharaoh of Egypt during the 32nd dynasty. I'm wondering if after his death was he mummified, also where is his tomb. Doing some research I've found a bust of Ptolemy wearing the Pharaoh's headdress and the false goatee. However, I have not been able to find a picture of Ptolemy's mummy or sarcophagus.

Any help, or links to further reading would be greatly appreciated!

Hey, first time posting here.

So i've been reading a bit on Alexander The Greats Wikipedia Page and i came across this

Praktisch unmittelbar nach dem Abzug des Heeres fielen die gerade eroberten Kleinstaaten Indiens ab und erhoben sich gegen die in den neuen Städten zurückgebliebenen Veteranen, über deren weiteres Schicksal in den wenigsten Fällen etwas bekannt ist.

Wich translates to

Immediatly after the Army left, the Smaller Indian states rebelled against the left behind Veterans, whos destiny is in the rarest cases documented

I am basically looking for those rarest cases documented, it absolutely fascinates me what those man must have went through so i am looking for all possible sources about the left behind Veterans of Alexander in India. Thanks in Advance!

I find hard to believe that they both could have visited every they made likenesses of, to me at least it seems likely there must have been earlier maps or writings they consulted.

Tanks had been landed directly on beaches before during the landings at Madagascar and Dieppe. What was the reason for launching the tanks at sea instead of offloading directly on the beach?

I've read that trenches were 50-250 yards apart which is well within rifle range. How were they able to dig trenches so close to the enemy without getting shot? I've never quite understood that.

Possible covert. If somewhere in the great war machine estimates to the number of villages destroyed, people displaced, casualty estimates from mass bombing. Of course, none would make great PR, but if historians have ever uncover a trove of data suggesting really detailed figures that were estimated. (crop lands/factories made unusable, agent orange burn estimates, schools destroyed....

In the US we all learn what sort of ingredients the Native Americans used: Bison, Maize, Squash, etc depending on the area. But what do we know about how these ingredients were prepared?

What sort of meals would the average native American prepare and eat? What about the chief and his family? Were there special dishes associated with specific days, like turkey on Thanksgiving?

If the source includes details of the life in the Republic that'd be great

I spent a few years on a tall ship and obviously enjoyed the delights of a modern healthy diet on board. I also learned about the horrible diets that crews of these ships had to eat BUT...

I never much evidence of crews (especially on naval ships) augmenting their diets with fish. Did it simply not happen? Was there some reason for not having fish on board?

Or did I just not find the evidence of it happening?

So I have an impression that race was treated somewhat differently in Louisiana compared to other regions in the deep south on account of the Creole population from the French period. Is this correct? and if so how was the treatment of free non Europeans in a slave state? On a related note how did the insular and anglo centered culture of the south integrate the non anglo Catholic French population?

If I understand it correctly, Fighter Command spent the mid-war period trailing their coat over France looking for a fight.

I also get the impression that these raids cost the RAF a lot of men and aircraft without any great result.

Would that be correct? Was there any useful purpose served by the Ramrod missions?

I appreciate that 'Aristotle' is an anglicisation of a name that has already passed through Latin and that 'Aristoteles' is closer/better english spelling. I have a passing familiarity with how 'Aristoteles' is pronounced in contemporary Greek but to what extent would if have been different in ancient greek?

Do we have a good reconstruction of the pronunciation differences between modern and ancient greek, in the way we do for Roman and Church Latin?

Perhaps naively i always saw the space shuttle programme as a science-driven project, a step away from the militaristic and political nature of the Space Race the previous two decades.

However, on yesterday's front page video of the first shuttle test flights people were commenting about how it was heavily driven/pressured by the US Air Force in its development and design, role and missions. Others claimed that this military involvement impacted on the safety and cost-effectiveness of the programme.

Can anyone shed some light on whether all this is true?

Maybe this is well-known in the USA, but i'm from the UK and had never heard about this before. I tried to look online for some information but most of it was either limited, glossed over or ignored.

Thanks.

Not sure how to describe these if you haven't played the games, but as a designer, I always try to imagine how someone would create something like a multi-ton that moves by the turning of one crank after having such-and-such items aligned perfectly on its face...

Were there civilizations that had amazingly involved mechanisms in their temples or elsewhere that I could check out?
