We’ll be honest. If you had told us a few decades ago we’d teach computers to do what we want, it would work some of the time, and you wouldn’t really be able to explain or predict exactly what it was going to do, we’d have thought you were crazy. Why not just get a […]
These days, most of the media we consume is digital. We still watch movies and TV shows, but they’re all packaged in digital files that cram in many millions of pixels and as many audio channels as we could possibly desire. Back in the day, though, engineering limitations meant that media on film or tape […]
Full marks for clarity of message. Credit: Euro Route materials When the Channel Tunnel opened in 1994, the undersea rail link saw Britain grew closer to the European mainland than ever before. However, had things gone a little differently, history might have taken a very different turn. Among the competing proposals for a fixed Channel […]
Having a gadget’s battery nestled snugly within the bowels of a device has certain advantages. It finally solves the ‘no batteries included’ problem, and there is no more juggling of AA or AAA cells, nor their respective chargers. Instead each device is paired to that one battery that is happily charged using a standardized USB […]
In the last edition of our ongoing series on how planets get ore– those wonderful rocks rich in industrial minerals worth mining– we started talking about hydrothermal fluid deposits. Hydrothermal fluid is the very hot, very salty, very corrosive water that sweats out of magma as it cools underground and under pressure. We learned that […]
If you want to print, say, a book, you probably will type it into a word processor. Someone else will take your file and produce pages on a printer. Your words will directly turn on a laser beam or something to directly put words on paper. But for a long time, printing meant creating some […]
As a classic car enthusiast, my passion revolves around cars with a Made in West Germany stamp somewhere on them, partially because that phrase generally implied a reputation for mechanical honesty and engineering sanity. Air-cooled Volkswagens are my favorites, and in fact I wrote about these, and my own ’72 Super Beetle, almost a decade […]
If there ever was a toy that enjoys universal appeal and recognition, the humble Rubik’s Cube definitely is on the list. Invented in 1974 by sculptor and professor of architecture Ernő Rubik with originally the name of Magic Cube, it features a three-by-three grid of colored surfaces and an internal mechanism which allows for each of […]
At 5:20 PM on November 9, 1965, the Tuesday rush hour was in full bloom outside the studios of WABC in Manhattan’s Upper West Side. The drive-time DJ was Big Dan Ingram, who had just dropped the needle on Jonathan King’s “Everyone’s Gone to the Moon.” To Dan’s trained ear, something was off about the […]
If I’m honest with myself, I don’t really need access to an off-grid, fault-tolerant, mesh network like Meshtastic. The weather here in New Jersey isn’t quite so dynamic that there’s any great chance the local infrastructure will be knocked offline, and while I do value my privacy as much as any other self-respecting hacker, there’s […]
