This month will always be #JuneDairyMonth to me, so this #SundayFishSketch subject represents it: The Milkfish. They’re found in the Pacific and Indian oceans, are the only living member of their family dating back to the Cretaceous period, grow to 5 ft long, and have no teeth.

Philology & the limits of typography: Christian Ravius, in his 1646 edition of the first two surahs, didn’t have Arabic type & used a clever workaround, giving a translation followed by a transliterated word-by-word gloss in numbered columns, which are noted in the translation

New "mystery creature" sighting in Pawleys Island, South Carolina. Lots of ridiculous speculation on what it is (marine reptile, alligator gar, sturgeon), but it looks like a squid to me. Maybe Thysanoteuthis?

Hardy once visited Ramanujan in the hospital and mentioned that the taxi he took had the number 1729 which he thought was a dull number. Ramanujan responded: "No, it's a very interesting number. It's the smallest number expressible as the sum of two cubes in two different ways."
