Were people appalled? Were they pleased? Were there articles about it in the mainstream press? Did any politicians, celebrities, academics, or other public figures comment on it? What did fans of Marilyn Monroe think?

What factors caused the rise and decline of the persecution of witches in witch trials during this period? Were they religious, social, economic, political or were other factors more key?

Today, we teach calculus to people as early as secondary school. I read that Oxford was granted a charter in 1248, at which point it was awarding specific "degrees" in various subjects. However, Calculus was not even invented until the 1700s.

Given that today, calculus is considered to be the foundation for higher education in mathematics, what would one study in the 1200s if they were pursuing a math degree?

Considering both metalworking and the Archimedes principle were known since Antiquity?

My main question is really is: Without stirrups, how effective would a charge have been?

I'm interested in learning history on my free time but I have no idea where to start. I wanna get insight into ancient Egypt, ancient Greece, all the way through to religious conquests and crusades, and so on up until medieval times and onto the world wars.

I don't think there would be such an exhaustive video detailing all these time periods of Arabia, Europe and all that so where should I start? Is there a specific linear timeline I should follow?

I am making my way through Riasanovsky's A History of Russia (5th) and I am mildly confused by the use of the phrase 'service gentry'. Apparently, estates and associated lands were given to the 'service gentry' for their service to the tsar, whereas in Western Europe landed gentry simply inherited their estates from their ancestors.

How did this work in practice? Did the owners of estates change frequently? I believe the 'service' provided would be both military and administrative; if you became incapable of providing that service, or if your father (the soldier) died, would your family be booted out and replaced by another?

A general discussion of the difference between landholding in the Russian system vs. European vassalage would be helpful.

Sir John Hawkwood for example. It seems like every time he turned around he was either being paid thousands of livres, ducats, or ecus to attack someone, or paid thousands more to not attack someone. Where would that treasure have been kept? Was banking an option or would he and his band of mercenaries just travel everywhere with a huge treasure train?

When i think Viking i think = raid, pillage and rape. But apparently there was more to it than that? Besides from writing the sagas what else did the Vikings do?

I have heard that it took only one generation for the Irish to be assimilated into American society. If that is true then how did it come about?

If so, where and what kind of tattoos? Did they even know haw to ink skin?

This may seem like a strange question but I've always wondered if Hitler truly was anti-semitic, in that he truly thought that Jews were a "lower" race, or was he, and the Nazi party, simply extremely pragmatic opportunists who used the anti-semitic culture of Germany at the time to gain power?

What happened to technology in the 20th Century? For hundreds and hundreds of years, humans traveled by horse, relied upon manual labor to complete tasks like planting crop, or washing clothes. Distant Communication only by letter(then telegraph in the 1800's).

Why over a span of hundreds of years did technology advance so little(in comparison), then all in one century we get: radio, T.V. the automobile, the aeroplane, capability to travel to space, electricity, telephone/cellphone, computers, the internet, all the medical advances...I'm sure I'm missing a few things.

TL;DR What happened in the 20th Century, that caused technology to advance more so than any other century?

Peanut butter is quite popular in the U.S., but as I understand it in many European countries it is an uncommon food. Is there any historical reason behind this, or simple chance?
