Linocut portrait of Marie Maynard Daly in purples (she’s a young m, smiling Black woman, wearing earrings, a necklace and a dress, looking at the viewer over her shoulder). Above her to the right is an anatomical heart with a blowout diagram in a circle of a clogged artery and the cholesterol molecule all in red. Next to her on the left in blue are the molecules of the bases which make up DNA and a diagram of a human cell.

For #SciArtSeptember day 9: heart, it’s trailblazing American biochemist Marie Maynard Daly (1921-2003), 1st Black woman to earn a PhD in chemistry in the US! 🐡🧪👩🏾‍🔬 #histsci 🧵1/n

She made important research contributions to the biochemisty of the cell nucleus & cardiovascular issues & chemistry of…

Hurricane Lee barrels through open Atlantic waters as the season's first Category 5 storm Hurricane Lee is charging through warm Atlantic waters as the season’s first Category 5 storm and threatening to unleash heavy swells across the northeast Caribbean.

Hurricane Lee is the season's first Category 5 storm (winds 157 mph or higher) & while it's not expected to make landfall it could generate 15-foot-tall waves across Puerto Rico's northern coast. Lee is 2023's 12th named storm; NOAA's new estimate is 14-21, & 5 of those could be major hurricanes 🧪

Happy birthday!! Your mum’s art is lovely

Color photo of Christa McAuliffe in a blue flight suit, floating in free fall during a training flight. There is a NASA patch on her right shoulder.

Teacher and astronaut Christa McAuliffe was born OTD in 1948. Selected as the first American civilian to go into space, she was one of the seven crew members onboard the Space Shuttle Challenger when it was lost in 1986.

Linocut portrait of Cecilia Payne-Gaposchkin in a lace collar in front of the sun in oranges and black against the blackness of space. At the bottom of the print is the solar absorption spectrum (a rainbow style gradient of indigo at left through to red and black at the right with specific discrete thin black vertical lines at various places).

Welcome to #SciArtSeptember! For day 1: starry, it’s #astrophysicist Cecilia Payne-Gaposchkin (1900-1979), who discovered what stars are made of & that hydrogen & helium are the most common elements in the universe.⁠ 🧪🐡🧑🏻‍🔬

So first day of school “count” for educators, how do you count?

A. Just job years
B. Student years + job years
C. Just student years
D. Something else?

Linocut portrait of Katherine Johnson in a upward gradient of raspberry to purple ink (she is a Black woman in a shirt dress, with pearls, glasses and a watch, holding a pencil, facing left with her arms out on an unseen table like she was writing, looking at the viewer over her right shoulder). Behind her on the right is the Project Mercury rocket with capsule and launch trajectory in black. Beside her on right is the Earth in blue with two images of the Moon in silver above to show the trajectory for the Apollo Lunar Module.

Happy birthday to mathematician and NASA scientist Katherine Johnson (née Coleman; August 26, 1918 – February 24, 2020). 🧪🐡👩🏾‍🔬🎢 One of the first Black women employed as a NASA scientist (+ predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics & 🧵1/n

Linocut portrait of a young Alice Wilson with her hands under her chin printed in gold ink. Behind her is her own geological map of the Ottawa Valley with the different features on collaged translucent Japanese papers in raspberry, purple, yellow, pale blue, and beige in inks of similar but darker hues. “OTTAWA RIVER” is marked but the final R is obscured by her head.

Happy birthday to geologist & paleontogist Alice Wilson (1881-1964).⁠ 🧪🐡👩🏼‍🔬⚒️

A black and white photo of Katherine Johnson sitting at her desk. She is wearing glasses and white or light dress with short sleeves and a collar. Johnson is looking to the right of the photographer. An analog adding machine sits on the desk in front of her, along with several papers and a translucent globe with multiple axes used for orbital calculations. She is holding a pen or pencil in her right hand, and wearing a bracelet or watch on her left wrist.

A color photo of President Barack Obama presenting Katherine Johnson with the National Medal of Freedom. She is seated in a red wheelchair, wearing a dark blazer and orange blouse. President Obama is leaning over her left shoulder, affixing the medal around her neck. She is looking up at him.

Mathematician Katherine Johnson was born OTD in 1918.

Her orbital mechanics computations played a vital role in many early NASA missions. Astronaut John Glenn trusted her calculations more than those of his onboard flight computer. 🧪 🔭 👩‍🔬

Blue linocut portrait of mathematician Karen Uhlenbeck on cream paper with hot pink diagrams and soap bubbles

Happy birthday to mathematician Karen Keskulla Uhlenbeck (b. 1942), winner of 2019 Abel Prize for “her pioneering achievements in geometric partial differential equations, gauge theory, & integrable systems, & for the fundamental impact of her work on analysis, geometry & mathematical physics.” 🐡🧪👩🏻‍🔬

A black and white photo of mathematician Karen Uhlenbeck. She is in her 20s or 30s in this photo, wearing a short skirt with a checker pattern, a dark blouse or shirt, a cardigan (or perhaps a light sweatshirt), and sandals. Her hair is dark and a bit longer than shoulder-length. The photo was taken outside and she is standing in the grass. There is a building and sidewalk behind her.

Mathematician Karen Keskulla Uhlenbeck was born OTD in 1942.

She is known for her work on PDEs, calculus of variations, topology, and gauge theory, and was the second woman (after Emmy Noether!) to give the plenary lecture to the International Congress of Mathematicians. 🧪 👩‍🔬

Looking forward to seeing all the cool stuff people are doing this year #iteachphysics
