source: The string can vibrate in different modes just as a guitar string can produce different notes, and every mode appears as a different particle: electron, photon, gluon, etc.
target: The string can vibrate in different modes. Every mode is a different particle: electron, photon, gluon, etc.
references: The string can vibrate in different modes. Every mode is a different particle: electron, photon, gluon, etc. The string vibrates in different modes just as a guitar string can produce different notes, and every mode appears as a different particle: electron, photon, gluon, etc. The string can go back and forth in different ways just like a guitar string can make different notes and every type comes like a different science part. The string can vibrate in different modes like a guitar string can make different notes, and every mode appears as a different particle: electron, photon, gluon, etc. The string vibrates in different modes like a guitar string, and every mode looks like a different particle:  electron, photon, gluon, etc. A guitar string can produce different notes, and the string can vibrate in different modes.  Each mode appears as a different particle: electron, photon, gluon, etc. The string can vibrate in different ways just as a guitar string can produce different notes. Every way appears as a different particle: electron, photon, gluon, etc. Strings vibrate in different modes like guitar strings do. Every mode looks like a particle. Some particles are electron, photon, and gluon. The string can vibrate in different modes.  This is like a guitar string that can produce different notes.  Each mode appears as a different particle, e.g. electron, photon, gluon, etc. The string can vibrate in different modes just as a guitar string can do different notes. Every mode will appear as a different item: electron, photon, gluon and so on.
