Hello To day I am going to discuss about the string theory well, it is off course not a normal string. This theory is the frame work of all physical happening since now. In this theory the point like particles that constitute to make other particles are replaced by one dimension strings these strings fluctuate or move as the string to sitar or violin vibrates well those vibrations causes melodious sounds or harsh noises depending upon the player but in the case of the quantum world string these vibration cause the change in particles bosons strings have different different patterns of vibration and same in the case of other particle strings
