Science Friday’s new podcast about science-inspired art is out now!

Dear Science Diction listeners, It is with sadness that we announce the finale of the Science Diction podcast. Starting with a simple newsletter and a passionate audience, the Science Diction podcast grew to serve up episodes on topics as varied as meme, ketchup, and juggernaut. It has been a joy to share these stories with you for the last two years. In celebration of Science Diction, we are sharing with you now a final mini-episode, a look back on this labor of love. You can relisten and...

We have a favor to ask! We want to know more about what you like, what you don’t, and who you are—it’ll help us make better episodes of Science Diction. Please, take our brief survey. Thank you! At the turn  of the 20th century, the American chestnut towered over other trees in Eastern  forests. The trees would grow as much as 100 feet high, and 13 feet wide. According to legend, a squirrel could scamper from New England to Georgia on the canopies of American chestnuts, never touching the...

For decades, vocal fry lived a relatively quiet existence. It was known to linguists, speech pathologists and voice coaches, but everyday people didn’t pay much attention to it. But then in 2011, people started noticing it everywhere. So what happened? What is vocal fry? Why does host Johanna Mayer use it? What's her problem? And is it really that bad? Guest:  Lisa Davidson is the chair of the Linguistics Department at NYU. Footnotes & Further Reading:  Check out this article on young...

In 2014, a grad student in Kolkata named Ujaan Ghosh came across an old book by a Scottish missionary. And as Ghosh paged through the book, he noticed the missionary kept using a word over and over: Juggernaut. But the missionary wasn’t using it the way we do today—to mean an unstoppable, overwhelming force. He  was using it to talk about a place: a temple in Puri, India. So Ghosh dug further, and as he grasped the real story of where the English word, juggernaut, had come from, he realized...

Head on over to plainlanguage.gov, and you’ll find a helpful table, dedicated to simplifying and demystifying military jargon. On one side of the table, there’s the jargon term, and on the other, its plain language equivalent. “Arbitrarily deprive of life”? Actually just means “kill people.” “Render nonviable”? Also means “kill people.” “Terminate with extreme prejudice”? “Kill people.”    This table is just one of many resources on plainlanguage.gov—from checklists to plain language...

When high schooler Gracie Cunningham posted a TikTok asking where algebra came from, she probably didn’t expect to become a viral sensation. There were the usual Twitter trolls, but some unexpected voices also began piping up, causing a flurry in the math world.Thank you to Chad, the listener who suggested that we do an episode on algebra. If you have a suggestion for a word or episode, leave us a voicemail. The number is 929-499-WORD, or 929-499-9673. Or, you can always send an email to...

This episode is a re-broadcast. It originally aired in November 2020.  Every year, the World Meteorological Organization puts out a list of 21 names for the season’s hurricanes and tropical storms. But in 2020, 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...

Journalists Kevin McLean and Shalina Chatlani join us for a round of Diction Dash, where Johanna tries - and usually fails - to guess the true meaning or origin of a word.    If you’re curious about a word, get in touch! Give us a call, leave a message, and we might play it on the show. The number is 929-499-WORD, or 929-499-9673. Or, you can always send an email to [email protected]. Guests:  Kevin McLean is a freelance producer based in Davis, California. Shalina Chatlani is the...

When Isabel Briggs Myers imagined that her homegrown personality test would change the world, she couldn’t have pictured this. Today, millions take the Myers-Briggs Type Indicator each year. Countless organizations use it, from General Motors to the CIA. But there’s one field that mostly rolls its eyes at the test: psychology.  In our final chapter, Isabel rescues her indicator from the verge of extinction, but has to make some compromises. And we explore what the Myers Briggs does (and...

At first, it seemed like Isabel Briggs Myers would have nothing to do with personality typology. That was her mother Katharine’s passion project, not hers. But when Isabel enters a tumultuous marriage, she discovers that her mother’s gospel of type might just be the thing to save it.  In Chapter 2, Isabel picks up her mother’s work, and decides to transform it into a marketable product—but first, she has to convince a group of skeptical PhDs that it actually works. Along the way, one...

If you’re one of the 2 million people who take the Myers-Briggs Type Indicator every year, perhaps you thought Myers and Briggs are the two psychologists who designed the test. In reality, a mother-daughter team created the test essentially at their kitchen table. In this episode, we look at the unlikely origins of the Myers-Briggs, going all the way back to the late 1800s when Katharine Cook Briggs turned her living room into a “cosmic laboratory of baby training” and set out to raise the...

Honeymoon: It just seems like a word that would have a lovely story behind it, doesn’t it?  When a listener named Eric emailed us from Centerville, Ohio asking about the word, that’s what we were hoping to find. Instead, we found a more bittersweet origin stretching all the way back to an early modern poem. Plus: We take a look at what’s going on in our brains during the honeymoon period—and whether it’s all downhill from there.  If you want us to cover a word on the show, get in touch!...

In 1910, a fruit fly geneticist named Thomas Hunt Morgan noticed something strange in one of his specimens. Out of his many, many fruit flies—all with brilliant red eyes—a single fly had white eyes. This fruit fly turned out to be a very big deal. From those white eyes, Morgan eventually figured out that genes can be sex-linked, confirmed that genes exist on chromosomes, and won the Nobel prize. But he also cemented his legacy another way, with what he chose to name that gene: "white". It...

What pigment do we owe to the squid? And what do you name a teeny tiny octopus that’s cute as a button? In this episode of Diction Dash, we’re talking about those clever and often tentacled marine invertebrates: Cephalopods.  Diana Montano, Science Friday’s resident trivia maestro, quizzes Johanna. But this time, Johanna calls in reinforcements—from Science Friday host Ira Flatow himself. If you want us to cover a word on the show, get in touch! Give us a call, leave a message, and we might...

If you read the title of this episode and cringed, you’re not alone. At Merriam-Webster, editors and lexicographers receive countless letters grousing about the addition of certain words to the dictionary. And here at Science Diction, we get our fair share of emails pointing out our linguistic missteps.  But the more you dig into the origins of words, the more you notice that when it comes to language, “correctness” is a slippery concept. In fact, some of our most beloved English words -...

How did a country's name end up inside the word, “serendipity"? And what’s a “syzygy"? And, more importantly, why does it have so many y’s?    Over the past year, several listeners have written to us asking about these two words. Now, we answer—with a little help. Eli Chen and Justine Paradis join us for a round of Diction Dash, where Johanna tries (and usually fails) to guess the correct origin or meaning of a word.  If you want us to cover a word on the show, get in touch! Give us a call,...

Last month, Science Diction received a letter from a listener named Ben. He wanted to know about ambergris, a strange substance that washes up on beaches from time to time. So today, we’re talking about this thing that for centuries, rich people coveted, rubbed on their necks, and even ate, all without having any idea what it really was. If they had known, they might have put their forks right down. Plus, Science Diction now has a phone number! If you, like Ben, want us to cover a certain...

When the first COVID-19 vaccines were approved for emergency use last December, it felt like - at last! - our nightmare was nearly over. Then came reports of botched distribution efforts, from broken websites to factory mix-ups. Scientists created the vaccine in record time, but it was beginning to look like that might’ve been the easy part. But if you think vaccine distribution was a logistical nightmare in 2021, try doing it in the early 1800s. In 1796, Edward Jenner discovered that cowpox...

Over the past year, you’ve sent us words you want us to cover on the show. And for months, we let those suggestions pile up into a list of nearly 200 words. Today, we begin to chip away at that lexical mountain. A team of Science Friday producers set out to tackle five listener-suggested words and quiz Johanna about their meaning or origin in a game we’re calling, Diction Dash. Feel free to play along... or just listen to Johanna get all the answers wrong.  We still want your suggestions! If...

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...

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...

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 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...
