One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory.

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

I believe that movies are fast becoming antique and dinosauric as a medium. Film is a medium for the over-40s and television has gone the same way. If you're going to look towards the new generation, then of course you're going to have to be a lot more random, spontaneous, irreverent and provocative with your programming.
