Something that seems like a subtle change can cause a catastrophic failure if it’s

http://tomscott.com – @tomscott – Things that can hurt you just by looking at them are science fiction and fantasy, right? Well, not quite. Inside Walt Disney World, home of the most terrible earworm known to humanity, I talk about the McCollough Effect.
http://tomscott.com – Or: what you see when you die. If you liked this, you may also enjoy two novels that provided inspiration for it: Jim Munroe’s Everyone in Silico, where I first found the idea of a corporate-sponsored afterlife; and Rudy Rucker’s trippy Postsingular, which introduced me to the horrifying idea of consciousness slums.
Herman Sörgel wanted to create the largest civil engineering project the world has ever seen: a colossal dam across the Strait of Gibraltar, lowering the Mediterranean sea. There were, of course, a few problems with this.

The Lorenbahn, the Lüttmoorsiel-Nordstrandischmoor island railway, is famous for the tiny, private trains that take residents to and from the mainland. But that’s not why it was built: and it’s got a more useful purpose as well. Thanks to everyone from Landesbetrieb für Küstenschutz, Nationalpark und Meeresschutz Schleswig-Holstein, and to the islanders, for all your
http://tomscott.com – @tomscott – Why don’t we use mixer taps? I’ve talked about the British plug before, and how it’s a wonderful design: British plumbing, on the other hand, still leaves a lot to be desired.
In the 1830s, two French brothers, François and Joseph Blanc, pulled off the first telecoms scam in history. The optical telegraph, a line of semaphore towers stretching from hilltop to hilltop, was for government use only: but something as simple as the law wasn’t going to get in their way. Thanks to Victoria Harrison for

I know, I know, it’s a clickbait title. But I stand by it, because the water is so deceptive, and so pretty, and there’s a path that leads straight down to it and that jump looks very, very possible… The 12th century legend is the “Boy of Egremont”, immortalised in poetry by the famous William
In a cemetery in Huelva, in Spain, is the grave of Major William Martin, of the British Royal Marines. Or rather, it’s the grave of a man called Glyndwr Michael, who served his country during World War 2 in a very unexpected way… after his death.

http://tomscott.com – http://twitter.com/tomscott – There aren’t many paternoster lifts left in the world: they’re inaccessible, tough to maintain and a bit more dangerous than a regular lift.

The mysterious YouTube algorithm. It’s confused people for years, and will continue to do so. So why isn’t YouTube more transparent? It used to be that they wouldn’t tell anyone how it works – but now, it’s that they can’t. Let’s talk about deep learning algorithms, neural networks, and search engine optimisation.

As far as I can find, no-one has actually made a International Standard Cup of Tea – ISO 3103 or BS 6008 – for the internet before. Lots of people have talked about it, but that’s easy. Making one?

In Crawfordsville, Indiana, there’s a rotary jail: an invention that, with hindsight, should probably never have been built. But it was, here and in other towns across the United States. It might have sounded like a good idea on paper, but in practice, it had a few unfortunate problems… including occasional accidental amputations. More about
The Berkeley Pit, in Butte, Montana, was once the richest hill on Earth: the Anaconda Copper Mine. Now: it’s not all that rich, and it’s not much of a hill.

If you’re sitting on a boat in Lake Constance, are you in three countries at once? Or just in one? Does it even matter?

http://tomscott.com – @tomscott – Why is an “odour” classier than a “smell”? Why is a “beverage” fancier than a “drink”? The answer lies in English history – and in the way we automatically know which ‘register’ of language to use. (Includes bonus medieval advice for constipation!)
Rue Canusa (or Canusa Avenue) is a street that’s split in two by a border: the northern part is in Stanstead, Canada, and the southern part is in Derby Line, USA — and border crossings here aren’t as easy as they used to be.

Over the Manchester Ship Canal, you’ll find the Hulmes Ferry, the Thelwall Ferry, and the Warburton Toll Bridge. They’re all strange in their own way, all under the control of one company, and all dating back to old laws and legal documents from a hundred years ago. I was in the area, so I stopped
About once a year, on the Oosterscheldekering barrier in the south of the Netherlands, there is NK Tegenwindfietsen: a bicycle race cycling into a headwind.
