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).

Feeding Time for an Ancient White Dwarf: The Case of LSPM J0207+3331
In this deep-dive, a Backyard Worlds citizen-science discovery reveals an ancient white dwarf, LSPM J0207+3331, that’s actively accreting the metal-rich core of a large, dry rocky body. Its atmosphere hosts 13 heavy elements—the most ever seen in this type of star—while a close-in silicate debris disk challenges models of planetary-system longevity. Ongoing accretion is confirmed by strontium, and hints of calcium emission suggest magnetic or heating processes we don’t yet understand. A dynam...
