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 🧵

My lino block print portrait for #PrinterSolstice prompt addition shows the amateur pioneering American scientist, inventor & women's rights advocate Eunice Newton Foote (1819-1888) who did the earliest experiments to show the insulating effect of certain gases & correctly concluded that increasing carbon dioxide levels would affect atmospheric temperature and climate, which we now call the Greenhouse Effect. 🧵

Day 11 #ArtAdventCalendar: Happy birthday to trailblazing US #astronomer Annie Jump Cannon (1863 – 1941), here with her stellar classification system which sorted stars based on spectral types, revealing their temperature from hot blue to cool red stars: O,B,A, F, G, K & M. Named the Harvard Classification after the university, her tremendous contribution was less visible. 🧵

Happy birthday to self-taught trail-blazing Irish #marineBiologist Maude Delap (1866 – 1953), 1st to successfully breed jellyfish in captivity & document their full lifecycle. She is surrounded by blue #jellyfish (Cyanea lamarckii) life stages based on her diagrams.

Born 7th of 10 kids to Rev Alexander & Anna Jane Delap in County Donegal, her family to Valentia Island when she was 8. 🧵1/

To history of science scholars that may be around: Do you happen to have any good refs on the history of chromosome linkage mapping, map units, the definition of the centiMorgan and so on?

Bonus #ArtAdventCalendar day 17 - Happy birthday to Gabrielle Émilie Le Tonnelier de Breteuil, Marquise du Châtelet (1706-1749), a natural philosopher, #mathematician and #physicist, shown here in my #linocut portrait with #diagrams from her ‘Principes Mathématiques de la Philosophie Naturelle’, a two-volume translation and commentary of Newton’s ‘Principia’, published in 1759 in French in Paris.⠀
