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).

Woolly Rhinoceros: The Ice Age Survival Machine of the Mammoth Steppe
Dive into Coelodonta antiquitatus, a woolly rhinoceros that dwarfed the landscape—3.5 meters long, with a fat-packed shoulder hump, dense fur, and a horn up to 1.35 meters used as a snow shovel to reach grasses beneath the snow. We unpack its cold-adapted toolkit—from an ossified nasal septum reinforcing the skull to its compact limbs and tiny ears—then explore the human story: hunting evidence, marrow-foraging, and rhinoceros-horn tools, plus depictions in Chauvet Cave. Finally, we trace its...
