It began as an obscure bug-checking program at Microsoft Research developed by a lone computer engineer named Leo de Moura. Then an unlikely crew of mathematical misfits caught wind of it and began to adopt it with messianic zeal. Their goal was to create a truth machine that could provide the rarest of all commodities in life: a complete, 100 percent guarantee that something is true. Its name: Lean.\nAs the movement grew and strengthened the program\u2019s capabilities, it drew in two of the world\u2019s most prominent mathematicians: Peter Scholze and Terence Tao. Google DeepMind, Meta AI, and other tech firms started using the program to supercharge computer reasoning. Now it\u2019s remaking the multi-thousand-year history of how mathematicians work, collaborate, and assess truth, while charting a\n\nThe Proof in the Code\nHow a Truth Machine Is Transforming Math and AI\nFree UK delivery on this item.\n\nThis brand new item is available with free UK delivery using Royal Mail track;
