#artAdventCalendar Happy birthday to #mathematician & #computerscientist US Navy rear admiral Grace Hopper (1906-1992) who popularized the revolutionary idea of developing machine-independent programming languages based on English.

She began teaching at Vassar in 31 & got PhD (Yale) in 34. She found marriage & teaching less fulfilling & tried to enlist in the Navy, but was rejected then got a special exemption to volunteer 🧵1/n

A 2023 #scientist #linocut for #ArtAdventCalendar of #astronomer Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & evolution of our universe! The Nobel committee waited 3 years after she died to reward another for the theory of dark matter.

She found 6 months mat leave post MSc very difficult 🧵1/n

For #ArtAdventCalendar Day 3, a new scientist portrait: my #linocut of ancient Chinese Han Dynasty #polymath & statesman Zhang Heng (78-139) who invented a seismoscope (a simplified seismometer which doesn’t record 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 & horizontal earthquake surface waves (Rayleigh waves in particular).
