Powerful statement from mathematicians around the world. “We urge mathematicians to discontinue their work with OpenAI and to return to a vision of science that centers human understanding.” The backlash to AI is only just beginning. terrytao.wordpress.com/2026/10/07/a...

They might not be flying, but it's certainly falling with style... Many species in the family Ommastrephidae are known as flying squids. They use their siphons to launch themselves out of the water and glide above the surface of the water like a squid rocket. #SQUIDtember
