Artisans revive the polissoir, a nearly-forgotten woodworking tool

André Roubo’s series on carpentry called L’Art du Menuisier mentions a polissior , a small device made of broom straw for polishing wood. In the two centuries since Roubo’s book, the device had faded from memory until a couple of years ago, when Don Williams recreated one from an illustration in Roubo’s book. It turned out to work amazingly well. (more…)

Conan the Barbarian: The Complete Collection – free Kindle edition

Here’s a free 853-page Kindle edition of Robert E. Howard’s Conan the Barbarian Stories . I got it and the formatting looks good, which is not often the case for free/supercheap ebooks. I read the reviews and people complained about missing chapters, but it looks like the publisher made corrections.

Dizzying designs by Peter Kogler seem to warp space

Peter Kogler projects or applies patterns to the surfaces of rooms that can be quite disorienting for anyone who enters. Most of his work uses warped black and white lines to distort the size and shape of floors, walls, and ceilings. He also makes a lot of cool creations involving images of mice and ants. • Peter Kogler site (via Colossal )

Why just four seasons? Ancient Japan had 72 microseasons

Spring. Summer. Fall. Winter. Boring. Ancient Japan had 72 microseasons each lasting about five days. They each have wonderfully evocative names like “Spring Winds Thaw the Ice” and “The Maple and Ivy Turn Yellow.” We just finished “The Bear Retreats to its Den,” and this microseason 64, falling immediately after the solstice, is called “The Common Heal-All Sprouts.

If you end up at some fancy event this month where gold leaf decorates the food, that gold leaf will be far thicker than traditional Japanese hand-pounded gold leaf, which can be as thin as 0.0001 millimeters. See how it’s made in the fascinating video. (more…)

First ever video of Ghost Shark, with sex organ on its head, alive in the ocean

Ghost sharks, aka chimaeras, are elusive relatives of sharks and rays that live in the black depths of the ocean, as far down as 2,600 meters. The Ghost Shark was captured on video by a remotely operated vehicle deployed on a geology expedition by the Monterey Bay Aquarium Research Institute in waters off Hawaii and California. The scientists who analyzed the video think that it’s a pointy-nosed blue chimaera (Hydrolagus trolli) that usually calls the waters off Australia and New Zealand home. This is the first time researchers have known this species to swim in the Northern Hemisphere. From National Geographic : Unlike those more well-known sharks, chimaeras don’t have rows of ragged teeth, but instead munch up their prey—mollusks, worms, and other bottom-dwellers—with mineralized tooth plates. A pattern of open channels on their heads and faces, called lateral line canals, contain sensory cells that sense movement in the water and help the ghost sharks locate lunch. And perhaps most fascinating, male chimaeras sport retractable sex organs on their foreheads.
