Why Are Rivers So Mathematical?

Why Are Rivers So Mathematical?

A river has my heart. It’s not the austere, black Thames winding through London, where I was born, but a lazy green one 5,000 miles away, where I spent my adolescence: the Blanco River in Texas. My maternal ancestors have dipped into its waters for generations, as I have on countless summer days. The Blanco … Read more

There’s a parasite in the ocean that doesn’t just feed on its host, it becomes part of it — Cymothoa exigua enters a fish through the gills, kills off its tongue by cutting the blood supply, and then attaches itself to the stump, living the rest of its life as the fish’s new, functioning tongue

There's a parasite in the ocean that doesn't just feed on its host, it becomes part of it — Cymothoa exigua enters a fish through the gills, kills off its tongue by cutting the blood supply, and then attaches itself to the stump, living the rest of its life as the fish's new, functioning tongue

Open the mouth of a snapper lying on a fishmonger’s ice and, every so often, something looks back. Not a tongue. A pale, plated crustacean roughly the length of a thumbnail, wedged into the floor of the mouth on seven pairs of hooked legs, sitting exactly where the tongue should be and doing more or … Read more

A child who can see 250 stars today may see fewer than 100 from the same place at eighteen: 51,351 naked-eye observations found the night sky brightening far faster than satellites had measured

A child who can see 250 stars today may see fewer than 100 from the same place at eighteen: 51,351 naked-eye observations found the night sky brightening far faster than satellites had measured

A child who can count 250 stars from home tonight may be able to see fewer than 100 from the same place at age eighteen if the recent measured rate of night-sky brightening continues. The stars would still be there. The difference would be the artificial light scattered through Earth’s atmosphere between them and the … Read more

Mercury is the Solar System’s smallest planet, but its metallic core fills about 85 per cent of its radius, leaving a rocky shell so thin that cooling has crumpled the surface into cliffs hundreds of kilometres long

Mercury is the Solar System’s smallest planet, but its metallic core fills about 85 per cent of its radius, leaving a rocky shell so thin that cooling has crumpled the surface into cliffs hundreds of kilometres long

Mercury is the smallest planet in the Solar System, but most of the distance from its centre to its surface passes through metal. NASA puts the radius of Mercury’s metallic core at about 2,074 kilometres, compared with a planetary radius of 2,440 kilometres. That is roughly 85 per cent of the planet’s radius. The percentage … Read more
