The Constant: A History of Getting Things Wrong

We give Aristotle a pretty hard time here at The Constant. But we can't hold an Aristotle-hating candle to the guy in this episode. A man whose distaste and distrust for Aristotle is responsible for the birth of the enlightenment, and--maybe--his own demise. It's time you got to know Petrus Ramus.

It started off as an innocent enough idea: what if the moon was made of ice? But from there it grew. Into an alternative-science, into a grand conspiracy theory and, finally, into one of the greatest evils in history. Learn more about your ad choices. Visit megaphone.fm/adchoices

Would you like a serious deep-dive into the technical history of cryptocurrency? Too bad. That does sound like something we'd do, but instead we're giving you a political comedy piece by host Mark Chrisler, performed for The Paper Machete, a weekly live magazine out of our hometown, Chicago Illinois. We'll be back next week with more sober examinations of historical ephemera. For this week, give yourself a little break. You've possibly earned it. Learn more about your ad choices.

In 1867, The Eliza set out to sea with a fresh crew, a full hold and fair weather. Yet no one expected her to ever make land again. This episode we look at why, and why, throughout the 19th century, hundreds of ships sank every year in entirely preventable circumstances. It's a story of high seas adventure, murder for profit and... a London coffee shop? It also happens to bear a more than passing resemblance to the gun debate happening in America today.

We could've called this show "Whoopsie!" or "Oops!" or "People Believe The Strangest Things." But instead, we called it "The Constant." On this, the season finale, we finally explain why. That means it's time to fawn about Einstein, and the thing he called "the biggest blunder of his life." It also means it's time for Mark to get a tattoo. Which... Look: let's not talk about it, okay?

Throughout time people have twisted the most humdrum of creatures until they were fantastical, bizarre, unbelievable monsters. From a logistically unfeasible hybrid to a self-castrating quarry, we're bringing you a suite of four stupefying animal myths, and then tracing them to their surprisingly humble beginnings.

This week: a whirlwind history of bad medical practices, worse medical practices and medical practices that--while still pretty awful--looked fantastic by comparison. Western medical history began with a madman who threw himself into a volcano to prove he was a god, and it only went downhill from there. For our story, we look at how one man managed to change 19th century medicine for the better, and how his discovery managed to make 20th century medicine worse. Learn more about your ad choices.

"Threatening the world with Famine, Plague and War: To Princes, Death! To Kingdoms, many Crosses; To all Estates, inevitable Losses! To Herdsmen, Rot; to Plowmen, hapless Seasons; To Sailors, Storms, To Cities, Civil Treasons!" -John Gadsbury, 1665. This week we get superstitious with comets, the great bearded stars that herald wishes made true. Or else fiery death. One or the other. For millennia mankind was panicked by these heavenly signs, not knowing what they were. And once we did find out what they were... well, then we panicked differently.

You don't know this story. You don't know the killer. You don't know the victims. You don't know the artist and you don't know the artworks. But in 1998 Yugoslavia, a series of mutilated corpses shocked the public, rocked the art world and, maybe, changed politics forever.  Learn more about your ad choices. Visit megaphone.fm/adchoices
