String theory

Dr Sandip Parimal Trivedi, TIFR
The Hindustan Times October 2, 2005

The new idea was to assume that the basic entity was a string, not a point particle. The string could virate in different ways, just like a sitar string does.The different resulting notes are the different kinds of particles, electrons, photons etc. There are six extra dimentions in string theory. These are believed to be curled up in small size, so that they have not been observed yet. A beatiful feature of string theory is that its differnt facets are closely tied together in tight logical consistency, so that progress in any area leads to ramifications for the whole subject.
