2 panel comic

Panel 1 is titled “Journalist logs into Twitter”
Image shows a Pink Guy performing a high jump. He easily sails over a tall barrier that says “Racism, Nazis, Homophobia, CSAM and Bigotry”. He smiles and waves at the reader.

Panel 2 is titled “Journalist logs into BlueSky”
The Pink Guy is doing the high jump again, however, this time, a much smaller barrier just says “Smugness”. The Pink Guy is clinging to the barrier, trying to hook his leg over it. He yells “Hnnngh I CAN’T GET OVER IT”

Today we celebrate the 150th anniversary of physicist Harriet Brooks's birth. Before marriage compelled her to give up her career, she was one of the world's most significant nuclear physicists, discovering the phenomenon of nuclear recoil, credit for which was stolen from her. tinyurl.com/mvcd3ape

Back from a long trip and in a weird state as far as dates go. But yesterday, June 28, I would have posted that physicist Maria Goeppert Mayer was born #OTD in 1906. She developed the nuclear shell model of the nucleus for which she was awarded the 1963 Nobel Prize in Physics. 🧪 ⚛️ 👩‍🔬 Image: APS
