After graduating from high school, without a clear plan for what to do next, Laura Andrews started asking herself a lot of questions. A spiral of big philosophical thoughts that led her to sit down and write to us with a question that was… oddly mathematical.  What is the most average size thing, if you take into account everything in the universe. So, along with mathematician Steven Strogatz, we...

But his an...

Meteorologists are as common as the clouds these days. Rolling onto the airwaves at morning, noon and night they tell us what to wear and where to plan our picnics. They’re local celebrities with an outsized influence. But in the 1940s, there was really only one of them: Irving P. Krick. He was suave and dapper, with the charm of a sunbeam and the boldness of a thunderclap. He was a salesman who t...

In this episode, first aired in 2014, we examine three very different kinds of black boxes — spaces where we know what’s going in, we know what’s coming out, but can’t see what happens in that in-between space. From the darkest parts of metamorphosis to a sixty-year-old secret among magicians, and the nature of consciousness itself, we shine some light on three questions. But for each, we contend...

This episode, co-Host Latif Nasser moderates a live conversation between Byrne and Neuroscientist Thalia Whe...

When people are dying and you can only save some, how do you choose? Maybe you save the youngest. Or the sickest. Maybe you even just put all the names in a hat and pick at random. Would your answer change if a sick person was right in front of you? In this episode, first aired back in 2016, we follow New York Times reporter Sheri Fink as she searches for the answer. In a warzone, a hurricane, a c...
