Velocity, wavelength, temperature define a particle's commonality or uniqueness. I see this as something fully explained in something I found called "The Resonance Principle. link removed
The scientist worked with a very creative artist and made a Five Part Animated Musical Video Book that expresses a very logical principle. After seeing it, I think you'll understand that every particle can be coalesced into an atomic structure for the sake of creating a usable material. If the particle moves at just the right speed, the movie shows how a single particle by its speed, temperature and wavelength can be unique, a photon, quark, graviton, neutron (speciallly unique and the key to magnetism) , or a proton, electron, et al. The principle explains all particles as existing in a spectrum. I think you would find watching it enligtning as enjoyable. And DO put on your headphone
