Holiday Bonus Episode with Jesse Case
Matt and Brooks are still out of town, so Andy sat down with Jesse Case this week for a special holiday bonus episode that's light on science, but heavy on the discussion of World War II bunker dogs, Jelly Bellies, porn, hospice situations, home videos from the 1980s, Beatles fandom, sleep-eating roommates and failed attempts to reach subglacial lakes. Enjoy, and we'll be back soon with full episodes and maybe even some Probably History!

Reading hidden topology in light, even when energy leaks away
When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar "knots" in how waves move through them. These are topological properties, labeled by whole numbers that don't change under small imperfections. That robustness is why topology has become one of the central ideas in modern physics. It promises electronics, photonics and quantum devices that tolerate defects and noise.
