An excellent post, Mr. Wenrich! Bravo!

I was at a Medieval Studies lecture many years ago, down at UNM, and, no, nobody in the Middle Ages who was literate - in English! - believed that the world was flat. That was an invention of the 19th Century, which apparently wanted to present the period as one of unrelieved darkness and squalor. I gave a copy of the lecturer's book on the subject to my engineer friend Duke McMullen for his birthday, to his delight.

And a casual inquiry a few minutes ago about the medieval beliefs about the shape of the earth brought up this scholarly page at first go:


‘The Earth is, in fact, round’ - Medieval manuscripts blog<https://blogs.bl.uk/digitisedmanuscripts/2018/05/the-earth-is-in-fact-round.html>
Albertus Magnus must have had some notion of gravity: in De Animalibus he gives three reasons why the earth is spherical: observational, based on the angle of Polaris at different latitudes, philosophical, because a sphere is the most perfect solid, and deducing that since meteorites everywhere fall toward the center, an object made up of them would remain spherical.

Don't get this wrong from the beginning. I am not talking about conspiracy theories or erroneous history texts. I'm talking about the things we encounter in daily life that give us new information or can lead us to do research.
For example, I recently streamed the movie "Hugo" and got a lot of information. No I don't think that there was an orphan boy living in a Paris train station maintaining the clock but one of the characters was Georges Melies (Sorry I don't know how to properly enter the accent marks.) and I knew very little about him. I only knew about his film "Trip to the Moon". Even more than an early film maker he was a stage illusionist who invented and/or popularized many of the first special effects. Without the movie I wouldn't have looked him up from other sources. One thing I learned, straight from the movie was that in filming, when the film was hand cranked, they used a metronome to keep the film speed smooth.
Another example is the things you can learn from simple YouTube videos if you can keep your selection positive. I've been watching, "How to ADHD" have learned some things that I found surprising but make sense. First, there is no difference between ADD and ADHD. Different people have challenges in different areas and not all are hyperactive. Hazel is ADHD. Brian is ADD. Although I'm too old to have been diagnosed as a child, I expect that I'm ADD as well. I'm certainly easily distracted and I am prone to hyper focusing. One thing I saw recently was about the calming bottle or glitter bottle to help come out of a meltdown. I was told to count to ten (or 100) in as many languages as I could. This might work better, I need to check with Hazel's parents to see if it has been tried.
>From one of the historical videos I learned that the Poles were not the complete pushovers to the Germans in WWII that a lot of textbooks would lead us to believe. They destroyed about 25% of the tanks the Germans deployed against them.
You can learn thing anywhere. Just check them for reasonableness and get multiple sources of information.

God bless you.
