See that? (No, behind me.) That's something you don't see every day! That's...drum roll...the largest island in a lake on an island in a lake in the world. (You may have to read that a couple of times; it's that kind of thing.) Treasure Island, Mindemoya Lake, Manitoulin Island, Lake Huron, Ontario.

Me standing at the shoreline of a lake. Behind me, perhaps 800 m offshore, is a long island, low at right rising to the left.

Barron Canyon, Algonquin Park, Ontario. 100 m deep canyon through Canadian Shield gneisses ("gneiss canyon you've got there") carved when this river was a raging outlet for post-glacial Lake Algonquin.

Some orchids from the collections of the Montreal Botanic Garden! The most diverse plant family on Earth. Warczewiczella amazonica (S America) Bulbophyllum mastersianum (Borneo) Epidendrum mainauanum (Ecuador) Angraecum ebumeum (Madagascar) 1/2

A single orchid flower peeking from the base of emerald green leaves. It's white with a delicate set of fine purple lines running from base to tip of the lower petal.A cluster of orange-red orchid flowers. The lower petal (lip) is very large and oval, the rest of the flowers are tiny, so t he effect is rather like a black-eyed susanA loose cluster of delicate lilac-tinged white orchid flowersA cluster or orchid flowers with white upper petals, greenish-yellow other petals, and long (several inches) nectar spurs like trailing straws from each flower.

I've also cited de Maupertuis... but in a different context from @mcnees.bsky.social! His description of an expedition north to measure the circumference of the Earth is an interesting example of earlier styles in scientific writing.

Astronomer and mathematician Pierre-Louis Moreau de Maupertuis, exact date of birth unknown, was born around this time in 1698 and baptized #OTD. He was among the first to articulate the Principle of Least Action, one of the most beautiful ideas in physics. 🧪 ⚛️ Image: Wellcome Trust

Etching of Maupertuis. His right hand rests on a globe and his left hand points to the site like a manicule from a broadsheet. He has a long, dark, curly wig on, and a robe tied at the waist with a sash.
