From the mystery of why elevator waits feel endless to the surprisingly tricky problem of splitting a pizza (or even a sandwich) fairly, this episode explores how math shapes everyday experiences in ways you might not expect. Host Rachel Feltman talks with physicist and editor Manon Bischoff about what hidden patterns lie behind daily frustrations, how shuffling a deck of cards involves mind‑bending odds and why math isn’t just for geniuses—it’s for anyone curious about how the world works.
