No, I don't mean missiles or anything...But rather, just experimental guns, such as the first designs of the automatic rifle... How did they form and shape the metal?

My history teacher told me that "most historians agree that Hitler had a Jewish grandparent." Is this true? If not, is this a popular belief among certain historians or are his beliefs unfounded?

Not talking the rich and powerful.

Im talking the average Blacksmith, Salesman, Crier, Shopkeep, military, leatherworker, tailor, barber ect.

If so, for what reasons has Switzerland always chosen to remain netural in European conflicts?

What I really want to know is when it was first discovered (because I've heard Shakespeare smoked weed)? And also, when did it become widely popular? And when did it become illegal?

Edit: in the US for all these

Maybe this needs scope, so let's say it's July 4th, 1776, and I've spent all day kicking Red Coat ass and I want to enjoy a glass of iced tea (because I'm innovative and also my wife won't let me have beer anymore.) Can I do it?

Let's also say I'm filthy rich.

What were typical rates in the US for home phones, and how were those rates changed by WWII? How does that compare to the rates of payphones in that time?

How did telephone operators handle calls from payphones if they weren't connected to payment plans, like party lines or individual lines?

Could you make long distance calls with payphones? Did that cost more? What about just to nearby towns?

The ideological transformation of Germany and Japan seems to have been so quick, painless, and complete -- but seventy years later, the idea that you could impose liberal democratic institutions via military occupation seems absurdly naive.

Why was there no meaningful fascist (or at least nationalist, or anti-occupation) insurgency in either country? How did the Allies convince the German and Japanese people to repudiate the ideology that had inspired such fanatical zeal during the war?

I've been reading about Gladstone's mission to the islands and he seems pretty dead set against the merging of the islands with Greece, what changed?

Were the Islands becoming too difficult to govern? Did Italian unification have any impact? The Suez canal was opened shortly before the islands were given away, why would Britain give away a base in the Mediterranean? Was there a change in the diplomatic situation in europe that meant they felt less at risk?

I'm finding it difficult to find reasons for them giving the islands away beyond 'philhellenism' and support for King George of Greece. There doesn't seem to be much in general histories of the era on the Ionian islands.

Can anyone help me out?

In such a context, mediaeval that is, would an event be able to occur ? 
And if it was possible in the medieval ages would it be possible in the early 19th century ? 

There are probably others, and there is probably some logic to this. Thank you.

I'm having a bit of trouble separating the current identity of the Uyghur ethnic group as muslims with the state religion of the ancient empire.

As they say, hindsight is 20/20.

What purpose/role did dogs play in Ancient Greece? If this question has been asked before I'll gladly delete this post.

Title says it all, thanks!
