We use verbal numbers and we use numerals - why do we need both? Why do we have the ones we have? What happened to Roman numerals? And what's loserish about the fiftieth Super Bowl? Stephen Chrisomalis, professor of anthropology and linguistics and author of the book Reckonings: Numerals, Cognition and History, returns to the Allusionist to explain our current numbers, and why we shouldn't get too arrogant about them. There's more about this episode, and a transcript, at theallusionist.org/numbers.

This is the Tranquillusionist, in which I, Helen Zaltzman, read all the salads from the 1950 recipe book 282 Ways of Making a Salad, with Favourite Recipes by British and American Personalities and Stars by Bebe Daniels and Jill Algood, with the purpose of giving your internal monologue a break by replacing it with some absolutely inconsequential words. Note: this is NOT the usual Allusionist. You will not learn anything about language at all, in fact the ideal outcome of the Tranquillusionists is that you’re asleep before the end.  Find all the Allusionist episodes - other Tranquillusionists and also ones that are actually about something - at theallusionist.org. The original music is by Martin Austwick. Hear Martin’s songs at palebirdmusic.com or on Spotify, and he’s @martinaustwick on Twitter and Instagram. And listen to his podcasts Neutrino Watch and Song By Song. Come to see me and Martin perform an all new Allusionist live show at the London Podcast Festival on 4 September 2021! Tickets to attend in-room or online are available via theallusionist.org/events, where you'll also find information about the Raise Three Fingers fundraiser for Myanmar that I'm cohosting with MiMi Aye in London on 22 August.

They're not ladies and they're not birds; they're not even technically bugs! But that's not the most surprising thing about ladybirds/ladybugs and their brilliant variety of names. Tamsin Majerus AKA Dr Ladybird explains why ladybirds are so great; and Johanna Mayer and Elah Feder of the podcast Science Diction, about words and the science stories behind them, consider what's in a (ladybird) name. This episode is one half of a collaboration with Science Diction, so go to their feed to listen to their episode It’ll Never Fly, where they set me a quiz about the outlandish and intriguing names given to fruitfly genes.
