The traditional formulation of the law simply corresponds to ignoring the subject. When I published a technical article about this (http://arxiv.org/pdf/1108.3080.pdf),2 I included a mathematical proof of the second part (how decoherence increases entropy), but a rigorous proof of the first part (that on average, observation always reduces entropy) eluded me, even though my computer simulations strongly suggested that it was true. Then something wonderful happened, which reminded me of why I’m so fortunate to get to work at MIT: an enthusiastic twenty-year-old Armenian undergraduate student, Hrant Gharibyan, asked if I had any interesting problems he could work on. We teamed up, and he attacked my problem with great fervor, devouring math books like popcorn and mastering mathematical tools such as Schur products and spectral majorization, which aren’t known to most physicists, and which I’d only learned of from my dad, who’s a mathematician. And then one day when I saw Hrant, I knew from his triumphant smile that he’d solved the problem! We’re hoping to publish his proof as soon as I’m done with this book.
