A Theory of Everything?
In this excerpt from his book The Elegant Universe, Brian Greene explains why string theory might hold the key to unifying the four forces of nature.
A Conversation with Brian Greene
The series host says we may not be smart enough to ever fully understand the universe, he'd like to know now if string theory is wrong, and more.
Viewpoints on String Theory
Leading physicists offer insights—and sometimes conflicting opinions—on the nature and meaning of string theory.
Imagining Other Dimensions
Our brains may not be equipped to picture ten spatial dimensions, but see if you can get to at least four here.

Starting at an everyday scale, travel by powers of 100 down into the infinitesimally itsy-bitsy world of strings.
Resonance in Strings
An everyday string and the tiny strings of string theory have a lot in common. It's all in the vibration.
Multidimensional Math
See for yourself why it's a walk in the park to dream up extra dimensions, at least for mathematicians.
