I worked as a geotechnical engineer for almost a decade, working on (amongst other things) landslides in mountain passes. It was a fun job!

I like this article. Geoscience isn’t well understood by most people, so I usually get reminded of the Gell-Mann Effect whenever I read a news article about it. But, this one correctly frames landslides as having created these feature in the first place, and that they were always going to fall at some point, rather than treating them as eternal features.

The features we see around us that seem so constant, like mountains, rivers, shorelines, lakes and seas, are all in a state of flux. Geological processes under some of our most populous cities are moving them by measurable amounts every year, and the numbers aren’t microscopic (up and down too, not just the sideways movement many people have heard about). Where once there were sea beds, there are now jagged mountains, and there will sometime be fields and then seas again.

Asianomics released a video on how withdrawing groundwater can dramatically lower the elevation of entire cities — I was surprised by how large an effect just a couple of years of human activity can have.

Around 10-15 years ago I read that Intel had a large somewhat secretive department working on exactly this idea, I believe the article described it as self-assembling sand or goo.

Anyone know what became of it?

Perhaps also interesting, an approach for bicycle tires that optimizes the thread pattern to cancel out road noise:
