Back before radar, the UK used these massive parabolic "acoustic mirrors" to pick up the sound of incoming hostile aircraft.
Now a 21c version of the same approach is being used in Ukraine to pick up low-flying radar-invisible drones. Soon in Poland and Estonia too. www.ft.com/content/0608...
Three concrete acoustic mirrors near Dungeness, Kent, UK. These structures were used to detect incoming aircraft before radar was invented.

Quite subtle, but I really like the little gold dots on the chrysalis of the Plain Tiger butterfly Danaus crysippus. Such a surprise when otherwise it's all bright green.
Chrysalis of the Plain Tiger butterfly. It's bright green, but has a row of tiny gold dots around it about a third of the way down.

God as a kid tries to make a chicken in his room
Image of a Larson cartoon with the caption "God as a kid tries to make a chicken in his room." A small boy is covered in soot, there is a smoking black pile of debris in front of him, some shattered lab equipment, and the air is full of feathers.

Timeline serendipity. I hope Labour MPs will "do justly now". There are other parties where they may find a kindlier political home - @greenparty.org.uk.
Picture of my timeline. Directly below Girl on a Brompton's post is one from @zarq.bsky.social with a set of quotations from various sources (described by @zarq here: https://bsky.app/profile/zarq.bsky.social/post/3lsa67jafhk2l). It says: "Do not be daunted by the enormity of the world's grief. Do justly now. Love mercy now. Walk humbly now. You are not obligated to complete the work, but neither are you free to abandon it."
