Some of the fruits of a year long project by photographer and professor Jessica Wynne to capture the thought processes (and physical efforts) of mathematicians via their chalkboard workings-out.
The entire set will be published as a Princeton University Press book next year.
The chaotic wiring poles of Dhaka, capital of Bangladesh. Messily repaired and overloaded with layers of cable for decades (the government has promised to phase them out by 2022) they’ve been captured for posterity as a metaphor for the country’s ‘entangled reality’ by local photographer Sounak Das.

Winners (and runners up) in the 2019 Audubon Photography Awards.
From top: a camouflaged owl by Shari McCollough; two Great Blue Herons by Melissa Rowell; Kevin Ebi’s shot of a Bald eagle and a fox battling for possession of a rabbit (see how it all turned out here) and the Grand Prize Winner – a red-winged blackbird ‘blowing smoke rings’ by Katherine Swoboda, who explains:
I visit this park near my home to photograph blackbirds on cold mornings, often aiming to capture the “smoke rings” that form from their breath as they sing out. On this occasion, I arrived early on a frigid day and heard the cry of the blackbirds all around the boardwalk. This particular bird was very vociferous, singing long and hard. I looked to set it against the dark background of the forest, shooting to the east as the sun rose over the trees, backlighting the vapour.
In fairness…
It’s very difficult to tell what’s going on at the centre of our galaxy, what with interstellar dust blocking the view of conventional telescopes. In other bands of light however, such as radio, it’s a pretty lively place. To wit:
The featured picture shows the inaugural image of the MeerKAT array of 64 radio dishes just completed in South Africa. Spanning four times the angular size of the Moon (2 degrees), the image is impressively vast, deep, and detailed. Many known sources are shown in clear detail, including many with a prefix of Sgr, since the Galactic Center is in the direction of the constellation Sagittarius. In our Galaxy’s Center lies Sgr A, found here just to the right of the image center, which houses the Milky Way’s central supermassive black hole. Other sources in the image are not as well understood, including the Arc, just to the left of Sgr A, and numerous filamentary threads. Goals for MeerKAT include searching for radio emission from neutral hydrogen emitted in a much younger universe and brief but distant radio flashes.
