Like the guns that were moved on train tracks

I've read about Hatsumi and Hayes, but I'm sure that neither of them are taken seriously within Japan's historical community. So, have there been any books or papers from trusted academic sources on the ninja and who they were recruited from, weaponry, etc. I'm not looking for a book or paper in a single language. I'll use a Japanese source.

I was watching Valhalla Rising again and it struck me that I could not recall any examples (at least in my mind) of where the native Celts or even Vikings opposed the influence of Christianity. This may be, because they eventually were consumed by the "White Christ" as it may be, and history is of course written by the victor. But do any of you guys know of a resource that I could read about the subject? It saddens me really, that so much of the Norse, Teutonic, and Celtic traditions are lost because of Christianity. Cheers and thank you in advance! :)

I've read multiple accounts of what happened during the course of the crisis, but wonder whether they felt any humility or self-doubt upon the safe conclusion of the crisis.

I watched America: The Story of Us and thought it was really fantastic and have been searching for something to scratch the itch of another similar type of series. Sorry if this is the wrong sub, but you lot seemed like the best people to ask.

I wish to learn about what Wales was doing during the times of Cnut and the Norman invasions. I'm interested in any book from the lives of common citizens to the kings of Wales and any events happening. Thank you in advance.

Couldn't find the answer googling. Edit: yeah Django Unchained.

I know that Lincoln at least wrote his Gettysburg Address, but was it normal at one time for presidents to write their own speeches? Is US presidents using speech writers a recent practice, or have they always done this?

I'm watching The Roosevelts on PBS and am struck with how eloquent FDR was, so it's got me curious...

Thanks!

I assume most people in history have gotten their strength simply from doing their work, but you have athletic competitions going back about as far as civilization started. When did people start specifically training for these?

How did they know they were planets and not stars? Did they name them after their gods as an honor or as some sort of ritual practice?

I'm currently playing catch-up on some music theory I've missed over the years, and today we came to ornaments. As it was explained to me, the acciaccatura is written with a line through it because it's optional if you play that note or not (NOTE: When playing piano, I've always been taught to perform it as a very short note before the written note). The appogiatura is the same on paper minus the strikethrough, indicating the note is obligatory. In that case, why not just write two eighth notes rather than an appoggiatura attached to a quarter note?

The answer I got was to do with castrati who liked to add flourishes their own way regardless of what was actually written, but that still doesn't explain how the tradition of writing an appogiatura ever started. It really does seem redundant and I'm not sure how castrati fit into recording music. Also my teacher seems a bit confused about ornaments, claiming that a trill and a mordent are the same, so this is another reason I ask.

I am in 7th grade and I just started micro schooling (which is a form of home schooling) In History I am supposed to learn about medieval to early modern I was wondering if anyone knew about any good resources for my learning. Also my sister is in 4th grade so she is learning about California and is looking for resources as well Thank You!

When I think about this question, I'm mainly thinking about sci-fi books, like Robert Heinlein, and Ray Bradbury's The Martian Chronicles. Visions of skyscrapers and flying-cars - Tomorrowland. Was the 20th century the only instance in history of such imagination, or have there been other times when people dreamed of such a drastically different world? If so, when? And, what encourages a culture to dream like we once did? Was it simply brought about by the industrial revolution and huge advances in science in the early 20th century? Did the wars of the early 20th century play any role in these technologically-utopian dreams?

EDIT: Also, Star Wars and Star Trek come to mind.

EDIT 2: Also, Isaac Asimov.

Is there any evidence stating what crops the early man planted? Do we know what the first people used as tools to plant their crops and how large the fields were? Do we know how large of a role crops played in feeding the first agricultural societies?
