Happy birthday to Wilhem Röntgen (1845-1923), the German physicist who discovered x-rays and earned the Nobel Prize for physics in 1901. I’ve depicted him in this thermochromic portrait at work, studying this mysterious, newly discovered, invisible form of light, based on a photograph of him in his lab, using a Crookes tube to produce x-rays. The form of the print mimics the nature of his discovery -

I knew, of course, that William Whewell first coined the word “scientist,” but I had no idea that the idea remained so controversial that Nature was still weighing in on the appropriateness of the term at least as late as 1925. https://www.nature.com/articles/115253a0.pdf #HistSTM #PhilSci #STS
It’s #BlackHistoryMonth so it’s a good time to celebrate the extraordinary 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 (and its predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics and played a pivotal role in the success of

Happy birthday to geologist Charles Lyell (1797-1875) who in his famous ‘Principles of Geology,’ wrote that to avoid some sources of prejudice in understanding #geology would require an Amphibious Being, who could, say, compare processes happening today on land & those happening below water with what we see in the geological record. 1/n
Happy birthday to trailblazing #programmer & #computer scientist, Beatrice “Trixie” Worsley (1921-1972). My #linocut shows Worsley seated at the first computer in Canada, the FERUT (which she named) & a flow diagram of one of her programs.
Trixie Worsley earned one of the first doctorates in computer science anywhere, & was supervised by Douglas Hartree and Alan Turing at Cambridge. 1/n
For the #Spacetober prompt history: my #linocut portrait of Nicolaus Copernicus (1473-1543) & his model of the celestial spheres, or as we would say, the solar system. Copernicus is shown in green with a lily of the valley, the standard Renaissance symbol to indicate a medical doctor, since like most proto-scientists, or ‘philosophers’ (doctors of philosophy) he learned his astronomy incidentally,

For the #SciArtSeptember prompt epilogue: 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’ from her epilogue to her ‘Observations upon Experimental Philosophy’. She’s an odd addition to my collection of scientists, … 1/n
When #physicist Lise Meitner (1878-1968) explained #nuclear #fission she understood nothing was “lost” (today’s #SciArtSeptember prompt) despite the missing mass after the reaction. She worked with chemists Hahn & Straßmann in 30s Berlin, investigating elements beyond uranium. They found bombarding nuclei of U-235 with neutrons actually triggered it to fission, or break, into 2 nuclei of roughly half the size & some free neutrons! 1/n

A nice review of #OilBeach has come in from Choice (American Library Association):
"harbors are regions of complex and global interactions between humans and their environment, complicating #biodiversity #conservation and restoration efforts... Highly recommended."
