Freedman's proof felt miraculous. Nobody at the time believed it could possibly work ?" until Freedman personally persuaded some of the most respected people in the field. But while he won over his contemporaries, the written proof is so full of gaps and omissions that its logic is impossible to follow unless you have Freedman, or someone who learned the proof from him, standing over your shoulder guiding you. "I probably didn't treat the exposition of the written material as carefully as I should have," said Freedman, who today leads a Microsoft research group at the University of California, Santa Barbara focused on building a quantum computer.
