About

I am a (recently) retired theoretical physicist, still active as "emeritus" in Université Paris-Sud from which I just retired. I am rather an SF fan, and particularly a great fan of Lois McMaster Bujold. Indeed, I participated in the reedition of the french translation of the first two-thirds of the Vorkosigan Saga in omnibus form, and the first translation of the books of the last third.
