I don't remember polaron positively. But did you know what a polaron is for real? From solid state physics, the polaron is...
"The object that results when an electron in the conduction band of a crystalline insulator or semiconductor polarizes or otherwise deforms the lattice in its vicinity. The polaron comprises the electron plus its surrounding lattice deformation. (Polarons can also be formed from holes in the valence band.) If the deformation extends over many lattice sites, the polaron is "large," and the lattice can be treated as a continuum. Charge carriers inducing strongly localized lattice distortions form "small" polarons."
Heh heh...he said polaron! [bustagut]
I do remember FrOnkOnsteen, Mr. Wilder.
