400 Years Ago, Galileo Discovered Four Jovian Moons
krswan writes "OK, the moons themselves are much older, but on January 7, 1610 Galileo first observed '4 fixed stars' surrounding Jupiter. Observations of their changing positions led Galileo to postulate they were really moons orbiting Jupiter, which became further evidence against Aristotelian Cosmology, which led to problems with the Roman Catholic Church, etc... Jupiter will be low in the southwest (in the Northern Hemisphere) after sunset this evening — nothing else around it is as bright, so you can't miss it. Celebrate by pointing binoculars or a telescope at Jupiter and checking out the moons for yourself."
Galileo!
MOON 1 [sings]:
I'm just a small moon
Nobody sees me
MOONS 2,3,4:
He's just a small moon
Smaller than Ganymede
GALILEO:
But wait! What? OH!
I think I've found Io!
MOONS 2,3,4:
He thinks he's found Io!
GALILEO:
I think I've found Io!
MOON 2:
GALILEO!
MOON 3:
GALILEO!
GALILEO:
FIGARO!

Dude, they used a different calendar 1 year ago.
To be fair to the pope, Galileo was a bit of a prick. To be fair to everybody who isn't a medieval reactionary, the pope used state power against Galileo just because of an argument they were having. .
The thing is that before Galileo published the book that called the Pope a simpleton, the Pope was Galileo's friend. Galileo was having a heated and nasty dispute with a scientific rival. This rival had connections in the Catholic Church that he turned to because Galileo was a prick and gratuitously insulted the rival. Galileo basically said, Nyah, nyah, nyah. the Pope's my friend. The Pope trumps your Bishop." The Pope said, "You are my friend, but these are powerful people. We need to tone down the rhetoric and get everybody to cool down. Galileo, you're the smartest guy I know. Write a book that makes the best case possible for both sides of the argument and I will get these guys off your back."br. Galileo wrote a book that made the Pope out to be a fool and called everybody who disagreed with Galileo on anything an idiot. If Galileo and his rival's positions on Heliocentrism had been reversed, the only thing that would have been different about Galileo's story is that very few people would have ever heard of him.

Score:1 Offtopic
Wow, I guess someone forgot to change someone's litterbox today.
I'll have you know that this is a musico-historical recreation of the moment of discovery of the fourth of the Galilean moons, encapsulated in a parody of a song depicting the senseless persecution of an innocent man.
My creation is also a bitter, post-modernist exploration of themes of alone-ness and alienation expressed as bodies adrift in the outer reaches of space, a veritable cri de coeur about the importance of attention to one's self-esteem and ultimate sense of being. It's a semiotical exploration of the most fundamental aspects of the human condition!
Offtopic, my keister! It's practically dripping with topicity!

Crumb's Corollary: Never bring a knife to a bun fight.
I've read extensively on the Galileo incident and I see no reason to change the the long accepted wisdom that it is a classic case of conflict between religious dogma and authority against scientific investigation..
I have however encountered quite a large number of people who have been persuaded by recent post-modernist type logic that in fact no; it was perfect alright and indeed correct for the church to threaten to burn Galileo alive because either/or
1) He was rude,
2) His finding would overturn centuries of dogma
3) Galileo's concrete observations were not good enough because he lacked the mathematics to describe them
Needless to say, I find such arguments unconvincing.
The Catholic church suppressed science. They threatened to kill Galileo and forced him to retract his theories. People often forget that last part. Galileo went to his grave holding that the Sun went around the Earth. You don't believe me? There's an official confession signed by him to that effect? You think he privately though otherwise? Tough; that confession is the end of the story. The church got what it wanted. Galileo and his works were suppressed.
I don't know exactly where this new apologia for the churches behaviour in the Galileo affair comes from, but I suspect it has more to do with US Culture Wars than actual critical thinking. Ironic, as for years the Galileo affair was a classic incident that Protestants held as demonstrating the abusive and backward position of the Catholic church. It's unfortunate that the relevant Wikipedia pages have been dragged into such revisionism, and in so doing have given it far more credit than it deserves. That's just another problem with Wikipedia and its monopoly on knowledge and viewpoints, but I'll leave that rant for another day.
May the Maths Be with you!
Thank you, this exact issue has been pissing me off for quite a while now. There's been a rather substantial movement to retroactive validate the Church's behavior toward Galileo for about a decade (maybe more, but that's how long I've been watching it). Galileo wasn't the most politically astute or generous person to his enemies, but he also didn't deserve the stuff the Church sent at him. The folio with his Inquisition record, for example, was clearly tampered with, with documents clearly added into places to make them appear older than they were.
In the end, Galileo's only defense should have been that his book was allowed by the Church censors. If there had been anything objectionable in it, they should have caught it and shot the book down. Failing that, they should have taken the blame, not Galileo.
As for making Simplicio a parody of Pope Urban, the only thing I've ever heard of that indicates that this was the goal was one quote from Urban put into Simplicio's* mouth. One quote a parody does not make; it's more likely (in my mind, anyway) that Galileo was trying to address one of Urban's objections and was clumsy in how he presented it. (On the other hand, as soon as it was found in the book, Galileo's enemies in the Church went to the Pope to decry Galileo. Note that the Pope didn't get offended on his own, he was goaded into offense.)
* Also note that the name was based on a real historical figure's name.
