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.” 🧵

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 🧵

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.”

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 & 🧵

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’. An odd addition to my collection of scientists, 🧵

For the #PrinterSolstice2526 prompt ‘even’ -the number of quarks in a meson, a type of particle first observed & published by Bibha Chowdhuri (1913-1991) & her supervisor D.M. Bose in extensive air showers from cosmic rays. My portrait shows her, a mountain on which she gathered her data & a schematic of the cascade of particles we find in cosmic rays.
Born in Kolkata, her family’s Bramohist faith quite unusually 🧵
