Science Diction

In 2013, introverts staged their comeback. For decades, they’d been told to get out of their shells and *smile*, while those  showy, gregarious extroverts were held up as the American ideal. But when one author published a kind of introvert’s manifesto, she sparked an introvert pride movement. Since then, the war of the ‘verts has only escalated, with self-identified introverts accusing extroverts of being shallow and incessantly chatty party monsters, and extroverts declaring introverts self-absorbed shut-ins who are just jealous because extroverts are actually happy. (A contention that studies support.)

It all feels like a very 21st Century, internet-era drama. But the history of the dubious and divisive introvert-extrovert binary began 100 years ago, when Carl Jung fell out with Sigmund Freud, and tried to make sense of where they’d gone wrong. In the process, Jung coined a couple of new terms, and unleashed an enduring cultural obsession with cramming ourselves into personality boxes.

In 1953, in the coastal town of Minamata in Japan, locals noticed some cats were acting strangely—twitching, spinning in circles, almost dancing. The reality was far darker. What looked like dancing was really convulsions. The cats drooled, spun in circles, and flung themselves into the sea. The cause of this strange behavior, residents discovered, was mercury.

Mercury—a silvery liquid, named for a quick-footed Roman God—has captivated humans since ancient times. It’s found in Egyptian tombs that date to 1500 BCE, and the first emperor of unified China believed it was the elixir of life. But what happens when it invades a town, and seeps into our brains?

Vervet monkeys steal it out of people's hands. Chimpanzees in Guinea are known to climb up palm trees and drink it. There’s even a theory that loving it was an important adaptation for our pre-human ancestors, that the smell of fermentation helped them track down very ripe, calorie-rich fruit. 

Alcohol has been deeply ingrained in our lives from the beginning, possibly since before we were human. And while the drive to drink is older than civilization, many have worked hard to reign it in. In 1920s America, these desires clashed like never before. It’s a story of a battle between chemists, and the unthinkable lengths the U.S. government went to to try to pry away our favorite mind-altering substance.

In 1920, a Czech writer was stumped. He’d written a play about a future where machines that looked like people do our bidding. They were the perfect workers: obedient, hard working, and never demanded a pay raise. But what was the writer to call these marvelous machines? There wasn’t yet a word for this type of creation. 

He had initially chosen labori, from the Latin for labor, but something about the word wasn’t quite right. It seemed...stiff, bookish. This play wasn’t just about machines who labored. It was about machines we exploited, relentlessly. And eventually, the writer landed on a word that fit better: Robot. 

Robot comes from an old Czech word for drudgery and servitude. Though in his play - like so very many robo-dystopias to come - the writer showed that a mind we create to serve us, isn’t necessarily a mind we can control.

On December 5th, 2012, a bill landed on President Barack Obama’s desk, meant to do one thing: remove the word “lunatic” from the federal code. This is because in 2012, you could still find the word in laws about banking and controlling estates, among others. And not only was it offensive, it was antiquated—ancient, in fact. The word lunacy comes from luna—Latin for moon. This is because there was a time when we thought the power to change our moods and minds came from the sky.

In the late 18th century, a doctor showed up in Paris practicing some very peculiar medicine. He would escort patients into dimly lit rooms, wave his arms over their bodies, and touch them with a magnetic wand. Patients would react to these treatments violently: crying, sweating, convulsing or shrieking. But then they would emerge healed. According to the doctor anyway. Many believed he was a fraud, but despite his dubious methods, this doctor inadvertently gave us a new approach to healing—and a new word: mesmerize. Because the doctor’s name was Franz Anton Mesmer.

Science Diction is back with a new season all about mind control—what happens when we decide to create new minds and they refuse to be controlled, why we’ve long believed the moon had the power to control our minds, and the extremes the government has gone to in order to pry us away from our favorite mind-altering substance. 

The first episode of our new season drops February 9th. Listen to a sneak peek above.

How did we wind up with a storm named Iota? Well, we ran out of hurricane names.

Every year, the World Meteorological Organization puts out a list of 21 names for the season’s hurricanes and tropical storms. But this year, the Atlantic hurricane season was so active that by September, we'd flown through the whole list of names and had to switch to the Greek alphabet. Thus, Hurricane Iota became the 30th named storm of the season.

We’ve only had to dip into the Greek alphabet once before, in 2005. But the practice of naming hurricanes goes back to the 19th century, and it was a bit of a bumpy ride to land on the system we use today. In this episode: The story of a meteorologist in Australia, a novel, and a second-wave feminist from Florida—and how they brought us hurricane names.

Guests: 

Christina M. Gonzalez is a doctoral candidate in anthropology at the University of Texas at Austin.

Liz Skilton is a historian and the author of Tempest: Hurricane Naming and American Culture.

The first Oreo rolled out of Chelsea Market in Manhattan in 1912, but despite the cookie’s popularity today, Oreos weren’t an immediate cookie smash hit. In fact, there was already another cookie on the block that looked remarkably similar to Oreos: two chocolate wafers embossed with laurel leaves, and white cream in the center. This cookie was widely loved, made with the highest quality ingredients, and saddled with a curious name: Hydrox.

So how did a cookie get a name so bad? Producer Alexa Lim takes us all the way back to the early 1900s, and brings us a story of the rise - and the crumble - of a cookie named Hydrox.
