One of the morbidly fascinating results of the 79 A.D. eruption of Vesuvius is the large number of holes found in the volcanic deposits around Pompeii that represented corpses of people and animals that were buried by the hot ash. The ash lithified before the corpses decayed so that a good mold of the deceased remained. Early in the excavation it was discovered that filling these molds with plaster produced remarkable casts of the victims of the eruption.

What do leopard spots, striped marine angelfish, and sand dune ripples have in common? Their patterns are self-organizing Turing systems! Discovered by Alan Turing in the 1950s, these repeating natural patterns can be created by the interaction of two things that spread at different speeds, one faster than the other.

I’ll See You Again In 25 Years - My Visit To The “Twin Peaks” Set In 1990
I’ve unearthed these pics of me as a goofy 12-year-old visiting the set of “Twin Peaks” in 1990. My mom won a raffle at my LA elementary school where the prize was to visit the set - they were shooting the beginning of Season 2 at the time, and they had moved their location from the Pacific Northwest to sound stages in Burbank, CA, where they had re-created all of the iconic “Twin Peaks” locations. The most surreal thing was that often the sets were built side-by-side, so I was able to step directly from One Eyed Jacks into Benjamin Horne’s office into Laura Palmer’s living room. The locations seen here are: Harold the meals-on-wheels hermit’s house (with Donna, Maddy and Harold), me with Mike the One Armed Man, The Double R Diner, Laura Palmer’s living room, One Eyed Jacks, the sheriff department’s jail, the piano in Donna’s living room, Benjamin Horne’s desk, a booth at the Roadhouse, and Josie Packard’s living room. On the day I visited, they were shooting the scene of Harold scratching his face menacingly with the rake - it adds a bit of amusing context to know that while Harold was raking his face, this funny-lookin’ kid was watching from off-camera! - Michael Lucid
