Linocut portrait of geneticist Irene Ayako Uchida (handsome, middle age woman of Japanese heritage with curly hair with a white streak on her right temple, with an open, thoughtful face) leaning on folded arms in a white button down shirt with a small watch with double-helix watchband on her wrist, in dark teal-grey ink. She is surrounded by chromosomes in gold, from one of her papers. The anomalous ones are pointed out with small pink arrows

Happy birthday to Canadian 🇨🇦 geneticist Irene Ayako Uchida (1917-2013)! 🧪🐡👩🏻‍🔬 #histsci In my #linocut Uchida is shown surrounded by chromosones, with anomalies (pink arrows) due to radiation exposure, based on one of her research papers. A strand of DNA is hidden in the image (as her watchband).⁠ 🧵

Black and white photo of the Moon’s far side taken during Apollo 16 in April 1972, as the astronauts were heading back to Earth. You see a wide and rugged view of the surface, covered with lots of overlapping craters and rough highland terrain. There are no large dark plains like those on the side we usually see from Earth. On the right edge, you can just make out a small part of the near side, including the dark round area of Mare Crisium. This picture was taken with the Mapping Metric Camera.

The Man Who Could Not Swim

He rebuilt a rotting sloop for $553.62, navigated with a smashed tin clock, and scattered carpet tacks on deck to stop pirates while he slept. 46,000 miles of open ocean, alone. Joshua Slocum: the man the sea trusted back, until it didn't.

The Man Who Found a Taste for Digging

He dug a wine cellar, found a taste for it, and kept going for forty years. His tunnels ran sixty feet in every direction. The clay had to go somewhere, so it went into the rooms above. William Lyttle: the man who traded his house for a hole.

Several of my linocut portraits of Claude Shannon laid out on a table to dry. He is in very dark teal blue, facing the viewer and wearing a suit. In front of him is the maze with electromechanical mouse and penny in forest green. Perspective makes it look like it’s coming out toward you. Behind him are binary numbers in silver.

The Squire Who Taught Darwin Everything

He rode a caiman like a horse. He climbed St. Peter's Basilica to leave a glove on top, then climbed back up to fetch it when the Pope demanded its removal. He dangled his bare foot from a hammock so vampire bats could feed on his toes.
