This article gives me an idea of what is String Theory. First what is the world made of, ordinary matter is made of atoms, and atom is made of three part, proton, neutron, and with the electron arranged around them. But neutrons and protons are made of even smaller particles, known as quarks. There are four fundamental forces in this universe: gravity, electromagnetism, and the weak and strong nuclear forces. Each of these is produced by fundamental particles that act as carriers of the force. The essential idea behind string theory is this: all of the different 'fundamental ' particles of the Standard Model are really just different manifestations of one basic object: a string.


This is a primary source, it provided me some important information of the my project, and this article let me easier understand the basic meaning of String Theory.
