C'est n'importe quoi , on privilégie trop les matières scientifiques en France. L'H-G serait une double matière négligeable , futile alors qu'elle a son utilité ? On peut aimer les maths ET l ' H-G ! C'est mon cas , j'ai eu mon Bac S , fait Math Sup , eu une Licence d'Histoire et tenté le Capes d' H-G. Vivent l'éclectisme et la richesse intellectuelle !

I ADORE Isaac Asimov, and the books that I keep near my Asimov collection in my bookshelf are some by Orson Scott Card, The Hitchhiker's Guide to the Galaxy, some short stories by H.P. Lovecraft, and lots by H.G. Wells. Also, Asimov has published so many short stories, maybe you could find another book that your brother hasn't read yet.
