My linocut print of Lise Meitner holding her glasses in one hand, while leaning on the other, in silver ink. In red ink is a nuclear fission chain reaction shown with a single neutron (white ball with motion lines) emanating from her head towards a nucleus (conglomerate of red proton and white neutron balls) then an arrow to it fissioning (becoming split into two adjacent then two separate halves with extra free neutrons). These neutrons in turn all begin the same process with other nuclei and the chain reaction takes up the left side of the print next to Meitner.
Happy birthday to #physicist Lise Meitner (1878-1968) who explained #nuclear #fission. 🧪🐡👩🏼🔬#histsci She worked with chemists Hahn & Straßmann in 30s Berlin, investigating whether there were any stable elements beyond uranium. They discovered bombarding nucleus of U-235 with neutrons actually 🧵
