I encountered the Phlogiston theory of heat with the work done by Count Rumford of Bavaria. He presented his findings regarding heat produced during the boring process of a cannon to the Royal Society of London. The belief by then was -as matter is subdivided, phlogiston or caloric will flow out of the material. - Count Rumford observed that when the boring device becomes blunt, as long as the boring device works against the cannon, even if there is no more further subdivision of matter (as the hole did not become bigger) still heat was produced. The caloric theory of heat or the Phlogiston theory died after that. This episode provided me the information that Lavoisier created the term -phlogiston-. He is the first husband of Madame Lavoisier. Count Rumford was able to put and end to the life of the Phlogiston theory but he was not able to extinguish the LOVE Madame got for her first husband, as Madame Lavoisier continued to carry that family name even if she married Count Rumford. Quite romantic?

Phlogiston is as wrong as describing electronics by invoking positively charged holes.
But aether was a totally different theory. Nothing to do with phlogiston theory nor chemistry in general. Off topic for this video.
The idea was that if light is a wave, what is waving? A wave on the ocean is the motion of salt water. So what is moving in a wave of light? Answer: aether. Which was then replaced by space-time itself, rather than a substance occupying space.

Love the way they use to bring bits of history to life!
By the way. I suppose, he is fluent in one language alone. This happens often when the chance to travel into foreign countries is statistically low.
So it is okay to butcher the pronunciation, as long as one is aware of it and acknowledges it.
(I'm just glad that they write the names out, and I don't mean only French, but German, Italian, Latin and Spanish too -. - )
Cheers!

Just one point on your maps at 0: 57 - at that time London is indeed the capital of the Kingdom of England (as this was before the UK existed) but the Kingdom included Wales during the whole of the 1600s. Your map shows England only, without Wales. At the time, Wales was a part of England in every way. It's only really since 1801 and the United Kingdom was Wales once again seen as seperate from England, as a constituent nation of the UK.

Wikipedia isnt reliable.
It isnt cited by reliable sources. It is anonymously contributed to by self confident people who dont use substantiated if any resources.
Wikipedia is generally garbage with a significant lack of knowledge
With Significant portions of false knowledge
And is highly biased
Based on the moderators themselves.

Interesting historical paralleles here. Huge growth in knowledge was stymied by politcally correct intellectuals. The salon culture was destroyed by the leftist revolutionaries and their gulloitine.

That-s so interesting for revolutionary France, as in the 1789 revolution they were SUPER obsessed with rationality and progress.
Then again, that-s probably why he made that appeal

Diderot is my hero. Also, your mention to -madame Lavoisier- felt forced and shoehorned, it seemed clear that you were just doing it to meet the obligatory gender quota.

-According to phlogiston theory, this ether was released during combustion-
Oh haha Valve, I just got that joke. The Phlogistinator? Cute.
