GoKawiilTerence Tao rebuilds 'QED' logic textbook into app called 'Lean Grimoire'
Mathematician Terence Tao has used a coding agent to modernize a 2018 interactive textbook called 'QED', which taught propositional and first-order logic as a puzzle game. The rebuilt version, working-titled 'Lean Grimoire', adds features such as displaying an in-progress Lean proof alongside gameplay and an optional fantasy-themed mode that reskins mathematical elements as potions and scrolls. Tao is now seeking playtesters to help refine the app as a teaching tool for logic and Lean.
