Back in the 1950s, facing the threat of nuclear annihilation, federal officials sat down and pondered what American life would actually look like after an atomic attack. They faced a slew of practical questions like: Who would count the dead and where would they build t...

One day in 1961, the famous physicist Richard Feynman stepped in front of a Caltech lecture hall and posed this question to a group of undergraduate students: “If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence was passed on to the...

Since the onset of the pandemic, we exist in a constant state of calculation, trying to define our own personal bubble.

Producer Sarah Qari uncovers the answer, and talks to some scientists who now say six might not be the right number after all. 

This episode was reported and produced by Sarah Qari and Pat Walters.

More than a million people have caught Covid-19, and tens of thousands have died. But thousands more have survived and recovered. A week or so ago (aka, what feels like ten years in corona time) producer Molly Webster learned that many of those survivors possess a kind of su...

In a recent Radiolab group huddle, with coronavirus unraveling around us, the team found themselves grappling with all the numbers connected to COVID-19. Our new found 6 foot bubbles of personal space. Three percent mortality rate (or 1, or 2, or 4). 7,000 cases (now, much much more). So in the wake of that meeting, we reflect on the onslaught of numbers - what they reveal, and what they hide.
