Happy birthday to #physicist Lise Meitner (1878-1968) who explained #nuclear #fission.

I usually don't post twice in one day, but I've been so excited about finishing this woodcut and showing it off: Ladies and Gentlemen----my latest woodcut: CARDINALS!!!!

It's a 6x12 woodcut on 8x15" paper--and there are only 18 in this edition. If you'd like to add one of these to your art collection (and support my work) I am taking orders on my website starting now.

Wishing a Happy Halloween to those who celebrate!

Happy birthday to #geochemist Charles David Keeling (1928 - 2005) whose decades long observations of CO2 in air samples from Mauna Loa Observatory were some of the 1st direct data to show the human contribution to greenhouse effect & global warming. The 'Keeling Curve' (in copper & red) shows both the seasonal variations (the wiggles) & the strong upward trend with time as the greenhouse gas built up in the atmosphere. 🧵1/

He also made pioneering microscopic observations on muscle fibres, bacteria, coffee & … 🧵1/n
