Most TV watchers are more curious about the properties of string cheese than of string theory. But in the ambitious new three-part “Nova” (WGBY at 8 p.m.; CPTV, 9) popular physicist Brian Greene goes ...

For decades, physicists have been trying to combine quantum physics and general relativity into a single, unified theory. One of the leading contenders is string theory, an elegant vision in which ...

In the last few years, excitement has grown among scientists as they've pursued a revolutionary new approach to unifying nature's forces. To the uninitiated, string theory is totally mind-boggling.

NOVA: String theory's great claim to fame is that it unifies the four forces. Why is unification so important? Weinberg: Unification is where it's at. The whole aim of fundamental physics is to see ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

Few prime-time TV shows would be willing to take on the bizarre realm of quantum mechanics and general relativity, string theory and 11-dimensional physics. But that’s just what “Nova” and physicist ...

String theory is an attempt to unite the two pillars of 20th century physics — quantum mechanics and Albert Einstein's theory of relativity — with an overarching framework that can explain all of ...
