Katherine Johnson died #OTD in 2020.

Her work included calculating trajectories, launch windows, and emergency return paths for Project Mercury spaceflights, including those for astronauts Alan Shepard and John Glenn, and rendezvous paths for the Apollo Lunar Module and command module on flights to the Moon. Her calculations were also essential to the beginning of the Space Shuttle program, and she worked on plans for a mission to Mars.

"We will always have STEM with us. Some things will drop out of the public eye and will go away, but there will always be science, engineering, and technology. And there will always, always be mathematics."

~Katherine Johnson (August 26, 1918 – February 24, 2020)

Another unknown birthday: Amongst the earliest recorded woman in #mathematics, Hypatia lived during the 3rd century AD in Alexandria, Egypt, which was part of the Roman Empire. She was born at some time between about 350 and 370 and died in 415 C.E. She taught philosophy, #astronomy and mathematics at a NeoPlatonist school. She believed in empiricism and natural law. 🧵1/n

My linocut portrait of Hypatia in purple holding an astrolabe up to her eye with her left arm while her right rests on geometric diagrams on sheets of paper on her table. Astrolabe and table plus diagrams are bronze in colour. I’ve shown her with curly hair piled up on her head, in a loose tunic with sash. Behind her are two Doric columns and arch.

#HappyNewYear everyone!

I am a #paleoclimate #scientist who also is an expert on #biomarkers as #ClimateProxies. In other words, I study past #climate using #molecular #fossils.

I am currently a @CNRS_INSU researcher at the Centre de Recherche et d'Enseignement en Géosciences de l'Environnement (CEREGE, France).

In addition to boosting toots of interest, I will essentially toot my new #scientific #publications and other #scientific content.
