En un material, un electrón ejerce fuerzas sobre los otros constituyentes y crea una pequeña bolsa de perturbación en su vecindad. Las excitaciones básicas que se producen en un material podrían no comportarse en absoluto como los electrones u otras partículas elementales en el vacío. De ahí que se les llama cuasipartículas. 1, record 1, Spanish, - cuasipart%C3%ADcula

Poussières d'origine extra-terrestre. De petites particules provenant de météorites pénètrent de façon constante dans l'atmosphère. La masse annuelle d'apport d'essaims périodiques de météores s'élèverait à environ 25 % de celle des météores sporadiques. [...] En comparant à différentes altitudes la concentration des particules d'origine terrestre et celle des particules d'origines extra-terrestre, on a pu avancer qu'à partir de 10 km d'altitude, l'aérosol d'origine extra-terrestre est prédominant. 1, record 4, French, - poussi%C3%A8re%20d%27origine%20extra%2Dterrestre
