Alok Jha on Eric Weinstein, a New York hedge fund manager who may — may — have solved the biggest riddle in science: the bridge between general relativity and quantum mechanics:

In Weinstein’s theory, called Geometric Unity, he proposes a 14-dimensional “observerse” that has our familiar four-dimensional space-time continuum embedded within it. The interaction between the two is something like the relationship between the people in the stands and those on the pitch at a football stadium - the spectators (limited to their four-dimensional space) can see and are affected by the action on the pitch (representing all 14 dimensions) but are somewhat removed from it and cannot detect every detail.

Exciting. But who knows. Certainly not me.

More from Marcus du Sautoy of Oxford, where Weinstein will be presenting his findings.

Steven Levy interviewed Ray Kurzweil about his new role at Google. On the topic of having the courage to follow your convictions:

Levy: What’s the biological basis for that kind of courage? If you had an infinite ability to analyze a brain, could you say, “Oh, here’s where the courage is?”

Kurzweil: It is the neocortex, and people who fill up too much of their neocortex with concern about the approval of their peers are probably not going be the next Einstein or Steve Jobs.
