Dead Ideas: The History of Extinct Thoughts and Practices

We explore ideas and practices once believed to be true but no longer. Each dead idea is explored in all its glorious eccentricity. For example, discover miasma, the theory that plague comes from stinky air; or the medical diagnosis of hysteria, which holds that women's wombs wander around their bodies causing trouble. Join us on a fun romp through the history of ideas that didn’t quite stand the test of time.

Canals of Mars


Is the surface of Mars criss-crossed by lines so long and straight they can only be constructions of an advanced alien civilization? Many astronomers in the late 19th and early 20th century thought so. Join us in this jaunt into the frailty of human perception.
