phonon in Science
phonon
  (fō'nŏn')   
The quantum of acoustic or vibrational energy. Phonons, like all quanta in quantum mechanics, have wavelike and particlelike properties. Phonons propagate through the vibrating material at the speed of sound in that material. Phonons are especially useful in mathematical models for calculating thermal and vibrational properties of solids.
