Se empieza con una colección de ejercicios prácticos, se añaden algunas fórmulas clave, se introducen problemas tomados de situaciones reales y se salpica con algunos párrafos de explicación: si uno divaga sobre un tema de esta manera, no teniendo el buen sentido de saber cuando ha de pararse, uno acaba escribiendo un OMNILIBRO. Esto es lo que ha ocurrido en este libro.

El químico escéptico es una de la obras más importantes de la historia de la química; en ella Boyle expone su hipótesis de que la materia está formada por átomos y combinaciones de átomos, siendo todo fenomeno resultado de su movimiento y negando asi que la materia este formada solo por cuatro elementos como afirmaba la alquimia. Ademas expone la independencia de la quimica como ciencia y la necesidad de comprobar experimentalmente todas las hipotesis antes de ser consideradas verdaderas.

Oliver Sacks evoca en este libro de memorias su niñez en Inglaterra. Cuando tenía seis años estalla la Segunda Guerra Mundial y es enviado, junto con su hermano Michael, a un internado en el campo.
