Happy birthday to #physicist Lise Meitner (1878-1968) who explained #nuclear #fission. 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 triggered it to fission, or break, into 2 nuclei of roughly half the size & some free neutrons! 🧵1/ https://minouette.etsy.com/listing/112254970 #linocut #printmaking #sciart #histsci #womenInSTEM ⁠

I asked an #AI model If, in a hypothetical #universe, the speed of #light is not constant & #energy varies with 'c' If we differentiate E=mc² twice with respect to c, what would be the consequences? It said this would destroy the universal causal structure. Stars would collapse, & many other things would happen. No #physicist could explain these outcomes Leaving hostility aside, AI is just a tool. It's up to you whether you use it for good or bad #stem #MultipleDomain #science #physics
