La química es la ciencia que describe todo lo que existe. A lo largo de veinte capítulos cautivadores, con un tono ameno y divertido, Héctor Busto desglosa las particularidades de la química y todas las formas en que interviene en nuestras vidas sin que reparemos mucho en ello, desde su aplicacion en medicina hasta la fabricacion de cualquier producto, ya sea en la industria alimentaria o la construccion de un rascacielos, la invencion de un color o la reproduccion de un aroma. Y aunque parece que tenga algo de magia, la quimica consiste en comprender (y transformar) la materia que nos rodea.
