<\/a><\/p>\nLa raison d’\u00eatre de ce blog, qui vient compl\u00e9ter ma Carte blanche d\u00e9j\u00e0 pr\u00e9sente sur Futura-Sciences, est de continuer \u00e0 contribuer, d’une autre fa\u00e7on et pour un public plus vaste et sans doute quelque peu diff\u00e9rent, \u00e0 la diffusion des connaissances sur un mode qui, pour \u00eatre plus l\u00e9ger et moins empes\u00e9, ne renonce ni au s\u00e9rieux ni \u00e0 la rigueur tout en s’autorisant la fantaisie et l’humour.<\/p>\n
Ce mode d’expression me permettra aussi des excursions vers des territoires qui ont toujours \u00e9t\u00e9 pour moi des lieux d’\u00e9vasion si essentiels qu’il m’est difficile de les dissocier de mon activit\u00e9 principale. Il m’arrivera ainsi souhaiter faire partager \u00e0 mes lecteurs les \u00e9motions que m’ont procur\u00e9es des lectures r\u00e9centes, ou anciennes et devenues des r\u00e9f\u00e9rences de chaque instant, ou des spectacles (concert, th\u00e9\u00e2tre, cin\u00e9ma,…).<\/p>\n
Le titre de ce blog est un jeu avec les lettres issues des deux mots Physique et Math\u00e9matiques : en tant que physicien th\u00e9oricien et enseignant universitaire, j’ai d\u00fb approfondir en parall\u00e8le ces deux disciplines afin de pouvoir les pratiquer et les transmettre au mieux \u00e0 mes \u00e9tudiants. Leurs interactions mutuelles sont si fortes et si profondes que, loin d’\u00eatre une cause de divorce entre deux communaut\u00e9s, ces deux pans de la connaissance humaine qui s’enrichissent mutuellement ne sauraient \u00eatre dissoci\u00e9s l’un de l’autre, ce que Galil\u00e9e et bien d’autres avant lui avaient d\u00e9j\u00e0 pressenti et que Eugen Wigner a formalis\u00e9 dans un article c\u00e9l\u00e8bre1<\/sup>, et d\u00e9finitif.<\/p>\n1<\/sup> Eugen Paul Wigner, “The Unreasonable E\u000bffectiveness of Mathematics in the Natural Sciences<\/em>“, Communications in Pure and Applied Mathematics, 13, 1 (1960)<\/p>\n","protected":false},"excerpt":{"rendered":"Durant des d\u00e9cennies d’exercice de mon m\u00e9tier d’enseignant-chercheur, mon premier souci a \u00e9t\u00e9 de transmettre les connaissances et les savoirs que, privil\u00e9gi\u00e9, j’avais eu la possibilit\u00e9 d’acqu\u00e9rir et d’approfondir \u00e0 toute occasion.
