In a stunning example of the power of the Internet to attract and connect the smartest minds on earth around the most difficult problems, scholars at UC Berkeley and Stanford have created a free website, called MathOverflow, which is transforming math research.
The format is simple. By linking questions and answers from hands-on participants, each small solution builds toward a larger understanding, accelerating research. And it proves that mass collaboration can greatly expand human problem-solving abilities.
