  • Likewise. Most of my "follows" on Mastodon are just various news junkies that summarize, link to and comment on breaking stories and broader investigations - with most of these drawing from numerous sources.

  • What to do When Your Foucault Pendulum Stops Swinging

    At the Houston Museum of Natural Science they recently made a disturbing discovery: their Foucault pendulum had stopped swinging for the first time since its installation in the 1970s. (Video, embedded below.)

    While some might take this as yet another sign of the end times, here it is simply a sign that the electromagnetic system that kicks the pendulum developed a fault and will need to be fixed.

    Their explainer video of this Herzstein Foucault pendulum is also worth watching, as it explains both the underlying physics and this particular pendulum’s construction. Every 48 hours the 81.6 kg heavy pendulum completes a full rotation, like clockwork, with pins along the circumference being tipped over one by one as the pendulum precesses.

    Invented by [Léon Foucault] in 1851 as an experimental demonstration of Earth’s rotation using a swinging pendulum, the Foucault pendulum remains a popular physical demonstration in museums and elsewhere. Although the pendulum seems to just follow the same line, it gradually shifts its plane of oscillation, making it seem that it rotates around its attachment point.

    The effect differs per region of the Earth globe, making it both a fascinating experiment and a sore point for those who insist that the Earth is a flat, unmoving disc.

    Not only does it measure the rotation of the Earth, but also its shape due to how the effect changes depending on the pendulum’s position on the globe, with the north and south poles showing it will precess in exactly 24 hours, while at the equator the pendulum will not precess at all.

    We hope that the repair of the mechanism behind the Houston museum’s pendulum progresses smoothly, and would love to see a video of its innards and repair.

  • I had ChatGPT put together a list of NBA feeds that don’t use paywalls. It’s been running a few days and the results are impressive. I’ll do a writeup of the list in next few days.

    An outrageous claim and the rabbit hole that followedAfter the trip to Genoa, I went to Rimini, on the other side of Italy, and visited the Italia in Miniatura theme park because it has a monorail. A simple loop around the park, with one station about as far from the entrance as it’s possible to get, it was a fun way to view the detailed scale models of famous Italian buildings below. But one thing caught my attention: a claim that this was Italy’s first electric monorail. Now, while the park was opened in 1970, the monorail wasn’t added until 2001 or so. This claim is somewhat dubious, when you consider that, not too far away, the Mirabilandia theme park had an electric monorail that operated between 1992 and 2019. Another theme park, Gardaland, has had an electric monorail since 1990.So, what was the first electric monorail in Italy?Well, Expo ’61 had an ALWEG monorail that was essentially the same as the one in Seattle. The Turin monorail. Jean-Henri Manara, Wikimedia Commons, License CC BY-SA 2.0One of the stations still exists, but my trip to Genoa reminded me that this isn’t the first electric monorail in Italy by a long way.The “Italian Colonial International Exhibition of Marine and Marine Hygiene” in 1914 had a quite impressive monorail, known as the “Telfer”, running along the seafront. A poster from the time describes it as a “Ferrovia Elletrica”, so definitely electric! After the exhibition closed, the monorail remained in use for a few years moving coal and goods around.During my visit, a friend and I tried to trace the route, and see if anything remained. Unfortunately, the way was blocked by a small military base, but we did find the spot where a large arch had been smashed into a building to allow the monorail to go through the Stella Battery.Roger Farnworth has written an excellent, copiously illustrated, article about the Telfer, so I will simply refer you there: Genoa – a TelferAnd that is, probably, the first electric monorail in Italy. The only earlier monorail I know about is a steam-powered, cable-hauled one that went up Mount Vesuvius.#1910s #1960s #2000s #genoa #italy #monorail #rimini #steampunk #Turin

    🚡🇬🇪 High above a Georgian mining town, rusting cable cars hang motionless on their lines. Built to carry miners and ore across the mountains, these small metal cabins were nicknamed "metal coffins" by the those that once used them for their daily commute.Nowadays, the cable car network is under renovation. But, some relic cars and Soviet Modernist stations can still be explored.Full feature live Saturday 8pm (UK)⠀#Georgia #Chiatura #History #Photography #Explore #AbandonedPlaces #Urbex
