TAFC.SPACE has a post which includes a map of the world as seen by a topologist. I.e. it doesn't show sizes or locations of countries, just which countries are next to which other countries. The actual map is near the bottom of the post but it's worth scrolling for.

An article in Nature reports on scientists who trained a deep-learning system with a large number of photographs of human retinas. After training, the system was able to identify the sex of the people in the photos with >80% accuracy. This is interesting because there is no known difference between male and female retinas. Naturally the system can't tell us how it tells the difference.

A tweet from the Canadian Warplane Heritage Museum has a picture taken from their Lancaster bomber on its first flight over Toronto. The picture was taken on 11 November 1988 and features the still-under-construction Toronto Skydome stadium. The picture also includes the RBC systems building where I had just started work two weeks earlier.
A Collection of Unmitigated Pedantry has a post on why trench warfare in the First World War worked out the way it did and why a stalemate and huge numbers of casualties are inevitable. It doesn't have anything to do with stupid or uncaring generals (though those certainly did exist) but with technology.
The trench stalemate is the result of a fairly complicated interaction of weapons which created a novel tactical problem. The key technologies are machine guns, barbed wire and artillery (though as we’ll see, artillery almost ought to be listed here multiple times: the problems are artillery, machine guns, trenches, artillery, barbed wire, artillery, and artillery), but their interaction is not quite straight-forward.
