I would like to add that Léon Foucault is the father of modern telescope as he was the first to make metal deposition on glass (it was chemical déposition of silver) and designed the first efficient telescope for modern astronomy. The last big telescope he designed was the 1.2 meter telescope for the Paris Observatory and it's still working in the Haute Provence Observatory.

I really like how your analysis takes into account what the socio political situation of the Catholic church was during Galileo's time. For some reason, that part of the story usually goes with some Church bashing, but you went with a deeper political insight instead. Strong kudos for this, esp. since this is an engineering channel. But about Copernicus' discovery, he wasn't really the first to come up with heliocentrism. Even in ancient greece some had the idea. So if the church hadn't slacked their homework, they wouldn't have needed another 200 years to finish it :)

Got some notions to pick over about Copernicus' revision. When Ptolemy finished with his astronomical work with epicycles and equants, the calculations could be used to compute even Mars' orbit (the oddest of the planet orbits) to within a gnat's hair, excepting only the retro-motion nodes, as close as the eye could see. When the instruments that assisted the eye got better, it was found that adding epi-circles upon the epi-circles could adjust to every discrepancy. When Copernicus exchanged the sun and the Earth, none of that changed - the orbits under Copernicus were still circles and the epi-circles were still required to match reality. Johannes Kepler managed to eliminate both epicycles and the discrepancies at the nodes by throwing out the circle and using the ellipse instead. Copernicus' math was easier than Ptolemy's (at least to our modern notation and sensibilities) but was no more accurate. Astronomers continued using Ptolemy's until Kepler. You can, using a series of epi-circles, draw any imaginable orbit. You get more accuracy by using more epi-circles. There are YT videos that tell you how to design a series that will draw any cartoon you care to explore; Homer Simpson seems to be the one of choice.

Epicycles are hidden within Fourier analysis which is used in almost any aspect of modern science, particularly electronics.

The church did not argue that this was not biblical or contradicted the bible but that it contradicted what Aristotle thought about the solar system, whom the church thought was right.it had nothing to do with the bible. This is a good example of Marx's re writing history.

Oftentimes Truth is more nuanced and complex than we want it to be to fit an elegant narrative. While it fits the narrative to make the Catholic church the superstitious villains in the story, they actually had their reasons for not embracing heliocentrism that had little to do with Bible verses. At the time the Catholic church had some of the best scientists around who said that if the Earth moved then the stars should shift positions - just like things appear to move when you close your right eye and then your left eye - but the best telescopes of the time were not seeing that because at the time they did not know how ridiculously far away the stars were. So one of the main reasons the Catholic church rejected the heliocentric model was because the theory did not match the best scientific measurements available - they were not seeing parallax of the stars.

Wasn’t long ago we had to unplug the TV so lightning didn’t strike it.

Bruno was executed because, even though he was a priest/friar, he denied the divinity of jesus. That marked him as a heretic regardless of whatever scientific beliefs he had. Galileo was given permission by his good friend, Maffeo Barberini / Pope Urban VIII, to write his book on the Copernican system as long as he followed the previous instructions of the head of the Inquisition in Italy, Roberto Bellarmini. Bellarmini had told Galileo that he could write a learned treatise on the mathematic and hypothetical motions of the Copernican theory. Galileo did not write it in Latin or in a learned manner. Worse while asking Ope Urban for permission , the Pope responded and was quoted by hi secretary as saying, "If God had wanted to put the Sun at the center of the Universe he could have. If God had wanted to put the Earth at the center of the Universe he could have. It's all the same to him." Galileo then had Simplicio (literally, Simpleton) repeat those same words in the book. Galileo had a great ability to argue for the right scientific concepts and the same ability to argue for incorrect ones (he believed that the moon did not influence the tides and that comets were atmospheric disturbances). Unfortunately, he insulted anyone who disagreed with him. Insulting Jesuits scholars was one of his greatest mistakes. They could have come to his aid when he needed help. At least he had the Medicis and their money helping out. It was through them that he got house arrest in his very nice villa with a servant, instead of jail. I'm not Catholic by the way.

So while there was a lot of solid philosophical, scientific, and engineering done then, later scholars would have to sort through the chaff and retain the important and factual bits. This is why the Arabic / Islamic treatment of the ancient Hellenic information is so important : the ideas were further challenged and expounded upon.

Our human history of science aught to be taught in 3rd grade as a beginning point. Your critical thinking on this history is very important and to the point. How refreshing.

Galileo was not punished for heliocentrism but for drawing theological conclusions from heliocentrism

Foucault also made a 1 million power optical microscope. It is specialized and shows irregularities on a telescope mirror as bumps. The irregularities' height appear to be a mm to about 5 mm above a flat surface. When the surface appears perfectly flat it is perfectly spherical. From that, using jeweler's rouge only the mirror is polished more in the center till it shows the perfect donut shape which means it is a parabola. Parabolic mirrors were made before that time but they were made by polishing the mirror to spherical (you guess) and then deepening it to parabolic (you guess). William Herschel not only made them for himself but for export. They were made of "speculum" alloy, sometimes called bronze. But bronze is copper hardened with a bit of tin and these were tin hardened with a bit of copper. One unsold Herschel mirror was taken from its sealed can (against corrosion) and given the Foucault test. It was a bit too deep for parabolic so it was a bit hyperbolic. But it was real good for a workmanlike guess. I made a 3" telescope mirror from ordinary glass (and abrasive powders from a jeweler) in my basement and made the Foucault test. It was most amazing to see it, knowing how much the magnification was. Besides the mirror itself all that is needed is a pinhole source of light (preferably monochromatic) and a razor blade.

Your videos are absolutely great. You should make more, split them into 10 minutes a piece and space out the release. Also, I would have signed up if you had patreon, and some collabs with history channels would be great too. This channel would blow up I think.

Also, note earlier in the video that all models for geocentric Earth, it is a sphere, that was known since antiquity. Basically, is the only explanation that changing latitude also changes the stars you see by the same angle. This is impossible on a FE. I'm sorry you lack the abilities to visualize this in your head, FE take advantage of that and you believe their lies. You said you are not a flat earther, well, this is one of their "reasons" and YES the pendulum proves it is rotating and the rotation observed on the pendulum depends on latitude. That is also impossible on a FE. So there you go, you are not a FE but spread their lies.

Copernicus studied the work of Arab astronomers before he came to the conclusion that our planetary system is heliocentric. However with this theory astronomers could still not reconcile star tables, until Kepler discovered that planets orbit in an eclipse - not a circle. This fitted the mathematical models and star tables perfectly, and today we still use Kepler's three laws of planetary motion to launch satellites or space travel.

No. He studied and credited the work of Aristarchus of Samos who did a trigonometric analysis between the Moon, the Sun and the Earth. Aristarchus reasoned that, based on his analysis, the Sun was much bigger than the Moon and therefore should not be orbiting the Earth. His ideas fell out of fashion because the Greeks could not conceive that the stars were so distant that, as Earth that orbited the Sun, you could not see a change of position for them. The one Arab astronomer who doubted the geocentric theory was Ibn al-Haytham, aka Alhasen, who calculated that Ptolemy's epicycles for Jupiter would interfere with the one for Mars.

Do you look at a modern car and see "stupid"? I might see the odd design mistake, but what I see is amazing technology that would have been absolutely impossible 30 years ago no matter how much time and money you threw at it. It's a bit cynical to write such things on a device that didn't even exist, on a video sharing website that hadn't even been invented, 30 years ago. What I do observe with sadness is the rise of regressive and even anti-scientific policies.

@@stefantrethan actually I do. In the first half of the last century we made leaps and bounds of progress. In the last 30 years all we've done is throw some electronics on the dash and pandered to a consumer who wants a new shapeless blob every year. I do a lot of work on newer cars, and know what's under the cheap plastic that falls apart after less than a decade.

It seems to me that science rides on the coattails of technology. I'm very skeptical that the scientific method or one's epistemology is as crucial to the development of technology as is stated by this video and so many others. Aristotle, Archimedes, and various Greeks were able to discover useful mathematics, technology, and science without going through any formal scientific method. So many technologies are based on superficially understood phenomena that science comes in and explains after the fact. That's why I find that science is too self congratulatory.

One of the best videos I´v ever seen. Mind blowing.

In the 1960'sd I worked as a student assistant for the physics department at the University of Wisconsin, Stevens Point. One of my first responsibilities was to create the electromagnet drive for the Foucault pendulum in the then new Science Building. Our pendulum was driven at the top rather than from below, using a large drill chuck for the iron mass and a Helmholtz coil for adding a small amount of energy to replace what was lost through air friction.

5:31 "Clearly says, in many places, that the earth is the centre of everything" I dont see anything about being the center of everything, not only this, but as an engineer, I know there are multiple meanings to the word "center" depending on its context. In addition, during the middle ages there was a lot of religious malpractice, so the contradiction, as you failed to find, wasn't on the Bible, but rather on the religious officials who claimed to have been "appointed by God", which is not explicitly stated in the Bible. Those religious officials also claimed that sins would be forgiven if you pay sacraments to the church. Its like if I were to say "I was appointed by God to write this comment." More like everything happens for a reason, which is according to God's plan. Perhaps this is a better interpretation.

Those scriptures are metaphors describing the steadfastness of nature as prescribed by God. Not that the Earth physically sits on a pedestal. You telling me someone took them literally?

"It's a metaphor" is what modern apologists came up with to smooth over all the discrepancies between scripture and reality. Historically there was nothing metaphorical about the bible, it was the literal word of god in the strictest sense possible and anyone who dared think different was to be burned on a stake.

@@aleksandersuur9475 So, when Christ says to go out and sow wheat, he doesn't mean spread the word of God - instead by your definition he means, to literally go plant wheat... Ugh... you're idiocy astounds me. And by that I mean your "pick-and-choose" dogma of only applying it to those things that meet your definition and calling it strict interpretation. lol

A very good presentation. Highly interesting. You bring to light many points that are not universally known by the common man. I will look in on future videos.

Good work on the video. I'm looking forward to seeing more from you. Also, My favorite Foucault pendulum is at the Buel Planetarium in Pittsburgh.

What a boring regurgitation of establishment propaganda.

then how exactly do you explain the movement of a pendulum? Your comment has basically no content. An empty hull, no argumentation, not even trying to proof something. Using words like Propaganda does not increase the value of your comment without any logical argumentation or some sort of proof. And please leave us alone with the "you can find the truth yourself if you just binge watch Conspiracy videos on youtube" bullshit.

​@@idontknow31212 "Galileo Was Wrong, the Church Was Right" by Robert Sungenis. Read the true version of the story. Galileo only proved Ptolemaic system wrong, but that did't automatically mean that the heliocentric one is correct. That meant that both neo-Tychonic and heliocentric COULD be correct. And to this day nobody proved only one of them correct, because all that we know today is that rotating Universe around fixed Earth generates forces eqal to "ficticious" forces on rotating Earth in static Universe. And since modern science simply doesn't have a clue what's the nature of inertia and gravitation, question of what is in the center reamains open. Same to all optical experiments. Stellar parallax and aberration only indicate that there's relative motion, but it does not point, what is fixed and what is really moving.

I love this video and this whole channel. Got to see the Vaucanson lathe AND the Foucault pendulum this past summer!

your work is invaluable

What a great channel. Kudos for doing what you’re doing. I’m your newest subscriber.

I grew up in Chicago, and visiting the Museum of Science and Industry, where I believe an exact or close to duplicate was always swinging for the nine years I lived there. It was an incredibly brilliant, and yet simple evidence that never stops. Thanks, never knew how to pronounce his name. Great video, never ceases to steal my attention.

Wicked video mate! Nice one. You feel science like I do. Might I suggest a story format video like this one but of Fred Hoyle, his stellar synthesis triumph along with his steady state ideas, his naming of the big bang (and why he named it such) and you could end with the absolutely shattering (to me anyway) that we are all made from the ash of long dead stars! I feel that your research - presentation skills, plus your obvious deep emotional feel for science, would do that story huge justice.

Thank you MT to sharing your knowledge.

You should have more views, really liked it, keep it up

Love your videos. Learned more and actually understand it, better than school.

Just discovered this video. Brilliant. I intend to recommend it. From Baton Rouge USA

Thank you for this wonderful video. Thank you for your concise explanations of processes and the history of everything, really. Everything stems from precise engineering. Everything.

I'm learning more from you than I ever did at school.

Thank you for your videos. They help me to appreciate that we live in a world of wonders and benefit from the hard work and ingenuity of quite a few remarkable people. You also discussed the role of the church in a nuanced way doing the times in which these exciting developments happened justice.

My new favorite KZread channel!

I really enjoyed the video, thank you. I have been struggling to get my head around the metal bar in the lathe going up and down is there any chance you could demonstrate that with a sphere and then a cube at the end of the bar? I don't have a lathe and my trials with a drill in a vice is not going well! Great KZread channel, thank you I'm thourghly entertained & learning lots.

BRILLIANT as always...Thanks

Incredible content! I wish you could find more time dedicated to history of technology since ancient times. I especially would love to see you research on evolution of mills and gears since for me this topic blow my mind how little I knew about it and I still don't see full picture how we got with it to the Industrial Revolution which for me isn't anymore such a surprise.

Loving these videos.

I can't be certain, but I think you've gained 4k subs in the last weekish... I wish I had found your channel earlier, because this content is pure golden original KZread

The Foucault pendulum I remember best is at the U.N. building in New York City. A pendulum always seems to fascinate me, grabs my attention along with something that flies. I'm really liking these videos. Thank you.
