A friendly tour of manifolds: how zooming in reveals flat space, how charts and transition maps stitch patches on curved spaces like the Earth, and how tangent spaces and metrics let us do calculus and physics on curved spacetime. From circles to spheres to general relativity, this episode unpacks one of math’s most powerful ideas. Brought to you by Embersilk (embersilk.com).

Bowhead Whales: Arctic Time Capsule and the 268-Year Giant
From a 19th-century explosive harpoon embedded in a bowhead to a living mammal that may live two centuries, this episode dives into the bowhead's ice-smart physiology, extraordinary lifespan, and genetic tricks that guard against cancer. We unpack their oversized mouths and four-meter baleen, the cooling radiators in the roof of the mouth, and the DNA repair mutations in ERCC1 and PCNA that promote genomic stability. We'll also explore their complex vocalizations, conservation status by regio...
