This week on Crash Course: History of the Scientific Revolution—astronomical anomalies accrued. Meanwhile, in Denmark—an eccentric rich dude constructed not one but two science castles! And his humble German assistant synthesized a lot of new, old, and bold astronomical ideas into a single sun-centered, eccentricity-positive system…

Could you please make a video about the Titanic

Weres history

Carewolf says:

You missed the most important part: Tycho rejected Copernicus model because it didn't fit the data he measured. Hypothesis rejected by experimental data.. Kepler then expanded on the hypothesis and found a model that did fit.

I want a proof for the area velocity idea

John Dorsch says:

Tübingen is pronounced similar to "to" + "begin", with the emphasis placed on the "to". So, Tü-bing-en ("bing" like the MS search engine).

Jamie Weiss says:

I am currently taking a summer semester class of exactly this subject-matter and this playlist has been immensely helpful, aiding in my comprehension of events, philosophers/cosmologists, and their beliefs. I can not talk you guys enough. Can't wait for the 14th video to drop!

Luluș Ione says:

How can you be such a fan of science and people who want to help and such a d!ck to Elon Musk at the same time? Dont you realise you are on the other side of what you adore when you do this?

MegaPhester says:

If you found the Tycho and Joahannes story interesting, and if you haven't already, I urge you to watch the episode of the originial Cosmos on this topic. Some of these stories deserve a movie or an HBO series or something, I swear.

asif imtiaz neon says:

is this series going to include Nicola Tesla at some point?

floooooooooooooooood says:

Francis Bacon was a scientist? Wow, some how I had absolutely no idea. And I've been to his gallery!

Tychoxi says:

There's a somewhat romanticized telling of this story in Carl Sagan's Cosmos.

Garrett Martin says:

How did CrashCourse skip over how Tycho Brahe died? Dying from a bladder infection from a refusal to leave a banquet because it would have been rude is a… unique way to die. Like so many other parts of his life.

Can we collectively agree that the idea that Copernicus or Galileo were persecuted primarily for religious reasons is debatable at best? That comes from a series of "just so" stories made popular in the early to mid-twentieth century. In actuality, the whole thing is a lot more complicated. At the risk of this being too late for anyone to notice, I'll go ahead and explain what I mean below:

To be clear, this does NOT mean that Galileo wasn't persecuted by the Church, but in pre-Napoleonic Europe the Church was a mix of both religious and political force. In other words, sometimes activities done by the church were solely driven by politics and power and less so than personal belief (even less so, religiously held belief). This is, in part, a reason that Enlightenment philosophies, particularly those of Locke (and thus the influence upon the USA) emphasized a separation of church and state (that's not the only reason, but it is part of the reason).

In fact, the work of Galileo had considerable support from many different groups within the Church at the time. The problem is that Galileo's ideas disproved Aristotle's principles. Aristotle's most famous and well liked (in Europe at the time) disciple was none other than the "dumb Ox" Thomas Aquinas. Thomas Aquinas was a Dominican, and though Aquinas was no longer alive at the time of Galileo, the Dominicans were a formidable religious and (more important for our purposes) political force within the church (and thus within Roman Catholic territories). There is no way they would stand by and let their beloved St Aquinas be tarnished, even if only by association, by some non-Dominican who disproved Aristotle. To be clear, others who were not Dominican did, at the time of Galileo, argue that a geo-centric model of the universe was not a tenant of any faith. Since as early as Augustine (mid-late 300s), there were strong arguments that, in his words, "only a fool would take Genesis literally." In fact the primary argument against Galileo from the Dominicans (other than their opposition to rejecting Aristotle) was to point to Joshua where he commanded the sun to be still. They argued that this was a Scriptural basis for saying that it was the sun and not the earth (for the record, the debate partner with this particular Dominican who initially used this argument literally laughed at such an absurd interpretation of the language). Eventually the Dominicans, over the objections of a respectable number of non-Dominican priests, canons, bishops, etc, convinced the Pope.

The rest, as they say, is history. Don't believe, necessarily, the writings of one Andrew Dickson White (first President of Cornell), who in the late 19th century pushed hard for a narrative that saw Christianity as the great enemy of intellectual progress. That's where a lot of these theories began. It's not true (or at best, much more complicated), and many of the best pushes forward in physics and biology were funded, directly or indirectly, by the Church. (sincerely, not a Roman Catholic, but a nuanced fan)

Not Johnny?

That makes Tycho Brahe a really hilarious combination of Pinocchio and the Hulk

Lon Bonner says:

At first I thought that was Rick Grimes in the thumbnail lol

Lunanime Animations says:

Why don't you make course on geology

Weedmoose Hecarim says:

For some reason after hearing about Tycho's nose incidents I can't get the picture out of my head of Michael Jackson throwing his nose at haters

Justin Huberts says:

Has Simon Stevin been mentioned yet?

SQW0 says:

It makes me wonder, among the flat Earth crowd who are so convinced of their name sake, how many also believe Earth is still the center of the solar system? Have these people been keeping their belief secret from their more scientifically minded flat Earth peers? Why hasn't there been a Earth Center movement in the US?

Johannes Høstrup says:

Level your goddam sound effects! This channel is the primary reason for my hearing-loss!!!!

Geoffrey Winn says:

Cool video!

Budget Hitman says:

Wasnt Tycho Brahe the drummer for Bon Jovi?

Hydra says:

All you need now to make this the Ultimate Learning Channel is #1 Get some Vsause who teaches Science & Technology, #2 Salman Khan, the founder of Khan Academy, one of the greatest minds for learning math from Kindergarten-Collage, Anyways I hope you Really consider doing this, Or at Least doing a Collab! Well that's all, Love you vids!! Much love <3 <3

Karl Young says:

Uh oh my nose is feeling loose… Galileo didn’t show that bodies fall at a uniform rate but at a uniform acceleration…
