At the turn of the 19th century, Britons would stroll along the Yorkshire Coast, stumbling across unfathomably big bones. These mysterious fossils were all but tumbling out of the cliffside, but people had no idea what to call them. There wasn’t a name for this new class of creatures. 

Until Richard Owen came along. Owen was an exceptionally talented naturalist, with over 600 scientific books and papers. But perhaps his most lasting claim to fame is that he gave these fossils a name: the dinosaurs. And then he went ahead and sabotaged his own good name by picking a fight with one of the world’s most revered  scientists.

For centuries, smallpox seemed unbeatable. People had tried nearly everything to knock it out—from herbal remedies to tossing back 12 bottles of beer a day (yep, that was a real recommendation from a 17th century doctor), to intentionally infecting themselves with smallpox and hoping they didn’t get sick, all to no avail.

And then, in the 18th century, an English doctor heard a rumor about a possible solution. It wasn’t a cure, but if it worked, it would stop smallpox before it started. So one spring day, with the help of a milkmaid, an eight-year-old boy, and a cow named Blossom, the English doctor decided to run an experiment. Thanks to that ethically questionable but ultimately world-altering experiment (and Blossom the cow) we got the word vaccine.

From the people who make Science Friday, we bring you Science Diction, a bite-sized podcast about words—and the science stories behind them. Hosted by SciFri producer and self-proclaimed word nerd Johanna Mayer, each episode of Science Diction digs into the origin of a single word or phrase, and, with the help of historians, authors, etymologists, and scientists, reveals a surprising science connection. For example, did you know the origin of the word meme has more to do with evolutionary biology than lolcats? Here's a sneak peek!
