Man, I’d love to get this pocket cipher machine at the upcoming Sotheby’s “History of Science and Technology” auction. (It’s $3,500, though.) Using an algorithm to co-write a sci-fi short story. How Linneas invented the index card (and thus, ultimately, the database). A book on the science of jellyfish (which, under global warming, may wind up ruling the planet). They may have found the bones of the original Saint Nicholas. LED traffic lights are so energy-efficient they don’t emit enough heat to melt the snow that gathers on them. Wow, when Time picked the computer as “Machine of the Year” in 1983, the cover illustration was creepy. Some proof that lightning creates antimatter.


"Desert necklace", a 1995 sculpture

“Desert Necklace” is a lovely and haunting 1995 work by the Dutch artist Peter Hoogeboom. A smartphone-shaped fidget gadget. NYC has genetically distinct “uptown” and “downtown” rats. Is life inevitable, as dictated by the laws of physics? Behold The California Review of Images and Mark Zuckerberg. Why social media traps in the eternal present: My latest essay for THIS magazine. Why analog circuits could make for faster, better neural nets. A Greenland Shark that may be over 500 years old. I dig, a new, stripped-down blogging engine. Amazon parody reviewers strike again! On War Primer, Bertolt Brecht’s multimedia book of antifascist poetry. On the cognitive impact of spreadsheets. Flash-photography powder, invented in Germany in 1887, was originally dubbed “Blitzlichtpulver”, or “lightning light powder”. NASA’s 1981 history of ball bearings.


Bremen Drop Tower

Enjoy 9 seconds of microgravity via Bremen Drop Tower. An in-the-weeds autopsy of why “Gangnam Style” broke Youtube’s counter. How different programming languages change what’s possible to make. A subreddit devoted to highly compressed code. (I learned of it via @Beschizza’s posting about a 218-byte spreadsheet, written in a single, convoluted line of Javascript.) A path to “quantum supremacy.” How a petticoat led to the first “man-lifting balloon” in 1783. VR goggles for the Commodore 64, via @gnat.
