Now if we join another brick, and another, we have a string made up of these bricks which we can build to any length we want. Assuming that we want to maintain some form of symetry we will need two types of brick say red ones (negative) and blue ones (positive). We can now make as much string as we want and use it to build the particles which we see in nature.
