Diatoms are a major group of algae found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth’s biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, […] and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara.

I had grasped long ago that diatoms where single-cellular plants. But somehow I missed the, “with shells,” bit. Diatomaceous earth suddenly makes sense. I had always pictured the microscopic little individual diatoms that I’d seen in books; various shapes and sizes, floating in water. But I hadn’t imagined the shapes, structures and types of shells they’re building out of silicon! Turns out, people interested in nanotechnology are particularly interested in diatoms. Wonders never cease.


Cognitive biases

Cognitive biases are systematic patterns of deviation from norm or rationality in judgment, and are often studied in psychology and behavioral economics.

While that may seem blasé, it’s worth a look.

…ok, back? Great.

Hey also, as far as I can tell, the word “blasé” correctly written as a word in English does include the diacritical mark. I wouldn’t have believed you if you’d told me there were any properly English words with accents, but it seems that this is now a thing in the last century or so!
