From Hackaday: “The Brennan Monorail was a train from the early 1900’s that seemed to defy the laws of physics. Not only did it keep itself perfectly balanced on a single rail, but it mysteriously leaned into corners without any driver input. This was a real invention – and it was unveiled to the public in 1910 by its inventor Louis Brennan. The idea was that using a single rail instead of two would make trains faster and railways cheaper to build. His train could take corners at greater speeds without being thrown off the tracks and railways would only need half the material. Unlike the monorails we’re familiar with today, which wrap themselves around tracks built high in the air, Brennan’s monorail could run on existing tracks. Although it looked a bit sketchy, it was very stable. At the heart of the train was a gyroscope that would correct the train’s tilt before the passengers noticed. This was a mind-blowing piece of engineering, especially for 1910.”

From Paul Kedrosky: “Something strange has happened to the word “delve” in the last two years. Its usage has exploded in everything from Amazon reviews, to undergraduate essays, to academic papers. There were, for example, more papers with the word “delve” in them in 2022 and 2023 together than in the prior 500 years combined. Everyone is on the delve train. It all has to do with a weird quirk of large language models (LLMs), understanding which requires a trip back through the Lord of the Rings, early American settlements, a 17th-century pastor, and Milton. Delving into something is a grandiloquent cliché and a quest for implied certainty. But it is also a cultural signifier, one with a thousand years of history at the intersection of religion, politics, science, risk, and literature, and one that is now being reflected back to us. Models are channeling all that history, in which is embedded our uneasy relationship with technology.”
