Happy birthday to #geologist & oceanographic #cartographer Marie Tharp (1920-2006), whose pioneering, thorough & complete ocean floor maps with Bruce Heezen, made using realms of echo sounder data, revealed the Mid-Atlantic Ridge.⁠
⁠
After studying #geology & math, Maurice ‘Doc’ Ewing at Lamont-Doherty Earth Observatory at Columbia hired her to draft 1000s of echo sounder profiles. Women were still not allowed to participate in

2025 is het jaar van de torenvalk. Nog steeds een van de meest geziene roofvogels in Nederland, maar ook de torenvalk heeft het steeds moeilijker in een verschralend landschap. Daarom dit jaar extra aandacht voor, en onderzoek naar deze karakteristieke jager.

Ik maakte een prent van de torenvalk en doneer een deel van de opbrengst uit de verkoop ervan aan @Sovon om hun belangrijke werk te steunen:

Happy birthday Rosalind Franklin (1920 – 1958), #chemist & x-ray #crystallographer whose x-ray diffraction images were instrumental to discovering double-helix structure of #DNA, made important contributions to #carbon & #virus research, was 1 of the great scientists of the 20th century.⁠

Watson’s bio lead some to (inaccurately) joke, “What did Watson and Crick discover?” “Rosalind Franklin’s notes.”

Happy birthday to 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 both women & Black scientists.⁠
⁠
Ball studied #chemistry at UW earning a BSc & 2nd degree in pharmacy 2 years later. She published “Benzoylations in Ether

Happy birthday to #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

Happy birthday to #astrophysicist Jocelyn Bell Burnell! In 1967, as a grad student she discovered the 1st radio pulsar, a highly magnetized, rotating neutron star that emits a beam of EM radiation. This radiation can only be observed when the star is pointed towards us; so, like the light from a lighthouse, it appears to pulse at a precise frequency. She had been working with her supervisor Antony Hewish & others to construct a radio telescope to study quasars. #linocut #printmaking #histsci

Happy birthday to brilliant trailblazing US #geologist & prof Florence Bascom (1862-1945) who championed women’s education, & used polarizing microscopes for detailed petrographic analysis to show that rocks previously identified as sedimentary were in fact metamorphosed volcanic rocks she called aporhyolite (implying a change in rhyolite, a silica rich igneous rock, as in her thin sections like the ones in my print).

New edition of fireflies coming soon!

This #linocut block print shows 3 fireflies (Photinus pyralis, the common eastern firefly or big dipper firefly) in a field against the night sky. These bioluminescent insects are the most common firefly in N America, & they use the light organ on their abdomen to signal potential mates leaving their tell-tale trail of a j-shaped flash pattern. Hence the common name “big dipper firefly”.

Marie Skłodowska-Curie and soon-to-be fireflies drying on my table. Mixed and printed all the glow-in-the-dark ink I needed at once for #radioactivity and #bioluminescence prints.

Summer is the time to make cyanotypes in the sun! This is a little 6” x 9” cyanotype of a day lily from my garden.

This is my common loon linocut based on a photo I managed to take from a canoe a few years ago.

We’ve begun to hear the cicadas again and I am reminded of my print.

This is a small handmade linocut print of a large, well-loved, well-known insect with a long song. The Tibicen canicularis, also known as dogday harvestfly or dog-day cicada, is common in North America and its power-saw like buzzing song is taken as a sign of summer. 1/2

This #linocut shows an obstinacy of buffalo in all senses of the words. The collective noun for a group of buffalo is a "obstinacy". Clearly, these are hard-headed beasts. These ones have drawn a line in the sand. I dare you to cross it. Technically, these are American bison (Bison bison), known colloquially in North America as 'buffalo'. These mighty beasts were once obiquitous across the Great Plains. 1/2

Happy birthday to #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. My portrait of Leavitt is printed in silvery lavender ink on Japanese kozo (or mulberry paper). Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco,

Un monotype fait hier dont je suis assez fier.
Ça devait juste être une étude rapide pour une future gravure, mais ça se tient pas mal en tant que tel.
Et si j'en fais une gravure un jour je doute de réussir des effets de texture aussi chouettes.

Happy birthday to #physicist Harriet Brooks (1876 - 1933) who discovered atomic recoil, Radon & recognized radioactive elements could undergo chains of transmutations into a series of new elements. #nuclear #physics⁠
⁠
She was Rutherford’s 1st grad student at McGill. After publishing her results in 1899 she completed her MSc in 1901 on “Damping of Electrical Oscillations,” before embarking on #radioactivity research.⁠

I printed some silly birthday cards with another one of my 3D printed relief plates...

I try to make a new card at least once a year to give to someone, and I usually put one in the Free Little Art Gallery as well.
