For #printerSolstice2526 prompt division here is my #linocut portrait of Agnes Pockels (1862-1935), the self-taught scientist who pioneered surface science.

As a woman she did not get the chance to go to university & study physics like her theoretical physicist brother Friedrich, who discovered the Pockels effect. So at 18 she took her "passionate interest for natural science" to her household chores &

My Lino block portrait of Agnes Pockels holding her pen and notebook by her trough (which was 70 cm by 5 cm and 2 cm deep, with a ruler along its length and a sliding divider). There is a button attached to an apothecary scale in the through so she can measure surface tension. She has her hair up and wears a dress and a cross on a necklace. She is surrounded by soap bubbles and you can see text in reverse for the Pockels point, 20 angstroms squared. She is in a gradient of dark forest green to lime from the base of the print upwards. The text, bubbles, and swirling patterns in the soap film in the front of her through are in pale pinkish purple.

Happy birthday to Kathleen Lonsdale DBE FRS (née Yardley, 1903-1971) who solved a longstanding #chemistry conundrum of the shape of benzene, here with her drawing of electron density for hexachlorobenzene (green) & model of hexamethylbenzene explore shape in different forms. Her husband said, “Before prison it might have bothered her to go to Buckingham Palace. Afterwards, Holloway or Buckingham Palace were all the same.” 🧵

My linocut with portrait of Kathleen Lonsdale in gradient of lavender at the bottom to indigo at the top. She looks like a serious woman with a big mop of curly hair, round glasses, in a floral shirt and blazer. To her left is her own first drawing of electron density projection calculated for hexachlorobenzene. In front of her in black is her own one crystal model of hexamethylbenzene (with spheres for atoms and bars to indicate bonds or for structure and a small tag).

Above the hotel is a glowing infinity symbol. The size of countably infinite sets, like all natural numbers {1,2,3, .... ∞ } is denoted by Aleph Nought ℵ0 shown on the two flags.

Each print is printed by hand in indigo, lavendar, mint green and dark navy blue ink on Japanese kozo (or mulberry) paper, 8” x 10” (20.3 cm by 25.4 cm).

you simply shuffle all the guests over one room and make room for the next guest. You can repeat this argument for one more guest, two more guests, three more guests, ...infinity more guest... infinity groups of infinite guests, etcetera!

The print shows a grand hotel on a steep angle (with a vanishing point at infinity of course), labelled “Hilbert’s Grand Hotel” below a cameo of Hilbert himself, and the slogan “No vancancy. Check in now!” 🧵2/

Happy birthday to Russian #mathematician & writer Sofia Vasilyevna Kovalevski (1850-1891). Her contributions to analysis, differential equations & mechanics include Cauchy-Kovalevski theorem & the famed Kovalevski top. She was 1st woman appointed to full prof in N Europe or to serve as editor of a major sci journal. She is also remembered for her contributions to Russian literature. All of this despite living when women were 🧵

She’s wearing a dress with puffed sleeves over a floral embroidered blouse. Her hair is up, her arms are folded in front of her and she looks thoughtfully to the side.

Another scientist in my collection with an unknown birthday is one of the earliest recorded women in science, Peseshet. She is described in the elaborate Saqqara tomb of her son Akhethotep,a royal official and overseer of priests, who lived during the Fifth Dynasty around 2400 BCE. She is described as the “Overseer of the Women Physicians.”

This is my linocut portrait of Peseshet, the earliest named woman in the history of science or medicine. She is described in the elaborate Saqqara tomb of her son Akhethotep,a royal official and overseer of priests, who lived during the Fifth Dynasty around 2400 BCE. She is described as the "Overseer of the Women Physicians." This linocut was printed by hand, using three blocks, in black, bronze, indigo and magenta ink on white Japanese kozo paper, 11" by 14" (27.9 cm by 35.6 cm). I have shown her dispensing medicine, with hieroglyphics spelling out her name (horizontally) and indicating that she was "wer snwnt per aa" or chief doctor (who happened to be female) of the great house (or palace).

Another of scientists without a known birthday: my #linocut of ancient Chinese Han Dynasty #polymath & statesman Zhang Heng (78-139) who invented a seismoscope (simplified seismometer which does not make a record of earth motions) to detect distant earthquakes & indicate their direction, 2000 years ago! Here with a reconstruction of his seismoscope, schematic of how it might have worked & 🧵

Above in pale pink at chest level is a waveform of a horizontal surface wave (especially Rayleigh waves) is overprinted on top. The seismoscope is shown as knee-high urn, cylindrical with dome top with small sculpture birds on top. Midway up are a circle of dragon heads with balls in their mouth (4 are visible). At the base are 4 visible open-mouthed frogs. In the schematic you can see a pendulum moves and released a ball which goes in one of the radiating troughs abs hits a lever which released the tongue and ball in one dragon mouth which drops a ball (after Feng Rui et al, 2014)

A splendid cold walk to Fiddlers Gill to see the fab but rusting Victorian #Braidwood Telescope! Once part of the now long-gone Lanark Observatory, its optics are safe at the Lanark Museum. Sadly I see no hope in restoring this beauty tho, that's been long-abandoned in this field ☹️ #histsci 🔭🏴󠁧󠁢󠁳󠁣󠁴󠁿

Starting 2026 with some unknown birthdays: Margaret Lucas Cavendish, Duchess of Newcastle-upon-Tyne (1623 – 1673), 17th-century English aristocrat, philosopher, poet, scientist, writer, with her imaginary world from her strange sci-fi novel ‘The Blazing World’ which she appended to her treatise ‘Observations upon Experimental Philosophy’.

The Empress, is a gold dress and crown is in the centre. To her right is a group of anthropomorphic animal scientists: a red northern cardinal-man, polar bear-man with white head, a pink worm-man, and a white goose-man.
