Happy birthday to one of greatest #mathematicians of all time Emmy Noether (1882-1935), here with her eponymous theorem, the backbone of modern physics. Noether’s theorem links any symmetry of a system with a conservation law. In my portrait, I chose to depict a young Emmy in front of a blackboard with a more simple formulation of her theorem and three specific applications of it, shown schematically,

"My methods are really methods of working and thinking; this is why they have crept in everywhere anonymously."
Happy Birthday Emmy Noether!!
She made many important contributions to abstract algebra. She proved Noether's 1st and 2nd theorems, which are fundamental in mathematical physics. She developed theories of rings, fields, & algebras. In physics, Noether's theorem explains the connection between symmetry & conservation laws.

March 22 is #WorldWaterDay and an apt birthday for Japanese #geochemist Katsuko Saruhashi (1920-2007) who created tools that allowed her to make 1st measurements of CO2 in seawater, raised the alarm about nuclear fallout, tracing it in oceans & researched peaceful uses of nuclear power. A supporter of women in science, she established the Society of Japanese Women Scientists & 1/n
One of the most exhausting things about being a (perceived) woman working in computational physics is dealing with men who don't think women can do physics and men who don't think women can code (there is a lot of overlap here). Things men have tried to 'explain' to me recently:
- Basic coding practices
- A topic I have published papers on
- How to debug a code ("have you tried adding print statements")
- How code releases work
- My own ideas

Happy birthday to Canadian medical researcher & #biochemist Maud Menten (1879-1960). Not only was she an author of Michaelis-Menten equation for #enzyme kinetics, she invented the azo-dye coupling for alkaline phosphatase, 1st example of enzyme #histochemistry, still used in imaging of tissues today & she also performed the first #electrophoretic separation of blood haemoglobin in 1944! 1/n

A Lab of Her Own
In her bedroom during WWII, she discovered how the nervous system is wired. On a cold, dry Tuesday in December, 1940, Rita Levi-Montalcini rode a train from the station near her home in Turin, Italy, for 80 miles to Milan to buy a microscope.

Happy birthday to botanist & photography trailblazer Anna Atkins (1799-1871), née Children!
Atkins’ mother died when she was still an infant, but she was close with her naturalist father & received a much more scientific education than was common for women in her time. Her 250 detailed engravings of shells were used to illustrate her father’s translation of Lamarck’s ‘Genera of Shells’; 1/n
Happy birthday to Caroline Herschel (1750 – 1848) a trail blazing woman in #astronomy. Hers was a real life Cinderella story, where rather than marrying a prince, she made a life and career for herself. Marriage her expected role but she was deemed unmarriageable, since a childhood bout of typhus stunted her growth. Her mother thought she should train to be a servant, & purposely stood in the way of her learning French, or music,
My ongoing series of portraits of #womenInSTEM for #iwd2025
For #InternationalWomensDay a short thread of my ongoing series of portraits of women in science through history. If you look for them, they’re there. I’m up to 67 now! Here’s to the day when a scientist’s sex is no longer remarkable in any field!

Lucy Evelyn Cheesman: the woman who walked.
Lucy Evelyn Cheesman (1881-1969), OBE, was an English entomologist best known for her extensive solo expeditions in the South West Pacific. Over the course of her trips, she collected around 70,000 specimens of insects, plants and other animals for the Natural History Museum.

Tu Youyou, a Chinese medical researcher, played a vital role in discovering artemisinin, the most powerful antimalarial drug therapy available today.
She found a key hint in a 4th-century BC medical text, which she combined with the insight that conventional techniques for extracting medicine from herbs might destroy the active ingredient.

Know her name: Caroline Herschel (1750-1848) made contributions to #astronomy that are still important to the field today.
Among her achievements: she was the first woman credited with discovering a comet (she found
8 in all).
“Herschel is just one in a long line of female astronomers who did not receive the credit they were due and whose work was used to justify prizes for male scientists instead.”

The next prompt for #printerSolstice2425 is sodium, which had me thinking of salt. To the alchemists (following Paracelsus) matter was made of various concentrations of three elements: salt, mercury and sulphur. So, for my next print I am working on a portrait of an alchemist who worked right at the transition from alchemy to chemistry (and pharmacy). 1/2
For #BlackHistoryMonth pharmaceutical #chemist Alice Ball (1892-1916) who developed 1st effective treatment for #leprosy. Though her life was cut tragically short, her research saved 1000s from exile & painful, ineffective lifelong treatment for leprosy, & she was a trailblazer for women & Black scientists.
Ball studied #chemistry at UW earning a BSc & 2nd degree in pharmacy 2 years later. 1/n
