  • Cartan meets Lacan

    In the Grothendieck meets Lacan-post we did mention that Alain Connes wrote a book together with Patrick Gauthier-Lafaye “A l’ombre de Grothendieck et de Lacan, un topos sur l’inconscient”, on the potential use of Grothendieck’s toposes for the theory of unconsciousness, proposed by the French psychoanalyst Jacques Lacan. A bit more on that book you […]

  • Bourbaki, Brassens, Hula Hoops and Coconuts

    More than ten years ago, when I ran a series of posts on pre-WW2 Bourbaki congresses, I knew most of the existing B-literature. I’m afraid I forgot most of it, thereby missing opportunities to spice up a dull post (such as yesterday’s). Right now, I need facts about the infamous ACNB and its former connection…

  • Le Guide Bourbaki : La Ciotat (2)

    Rereading the Grothendieck-Serre correspondence I found a letter from Serre to Grothendieck, dated October 22nd 1958, which forces me to retract some claims from the previous La Ciotat post. Serre writes this ten days after the second La Ciotat-congress (La Tribu 46), held from October 5th-12th 1958: “The Bourbaki meeting was very pleasant; we all…

  • Le Guide Bourbaki : La Ciotat

    Two Bourbaki-congresses were organised at the Côte d’Azur, in La Ciotat, claiming to have one of the most beautiful bays in the world. La Tribu 35, ‘Congres du banc public’ (February 27th – March 6th, 1955) La Tribu 46, ‘Congres du banquet auxiliaire’ (October 5th-12th, 1958) As is the case for all Bourbaki-congresses after 1953,…

  • Le Guide Bourbaki : Royaumont

    At least six Bourbaki-congresses were held in ‘Royaumont’: La Tribu 18 : ‘Congres oecumenique du cocotier’, April 13th-25th 1949 La Tribu 22 : ‘Congres de la revanche du cocotier’, April 5th-17th 1950 La Tribu without number : ‘Congres de l’horizon’, October 8th-15th 1950 La Tribu 26 : ‘Congres croupion’, October 1st-9th 1951 La Tribu 31…

  • Le Guide Bourbaki : Marlotte

    During the 1950ties, the Bourbakistas usually scheduled three meetings in the countryside. In the spring and autumn at places not too far from Paris (Royaumont, Celles-sur-plaines, Marlotte, Amboise…), in the summer they often went to the mountains (Pelvoux, Murols, Sallieres-les-bains,…). Being a bit autistic, they preferred to return to the same places, rather than to…

  • The (somewhat less) Secret Bourbaki Archive

    It has been many, many years since I’ve last visited the Bourbaki Archives. The underground repository of the Bourbaki Secret Archives is a storage facility built beneath the cave of the former Capoulade Cafe. Given its sporadic use by staff and scholars, the entire space – including the Gallery of all intermediate versions of every…

  • Princeton’s own Bourbaki

    In the first half of 1937, Andre Weil visited Princeton and introduced some of the postdocs present (notably Ralph Boas, John Tukey, and Frank Smithies) to Poldavian lore and Bourbaki’s early work. In 1935, Bourbaki succeeded (via father Cartan) to get his paper “Sur un théorème de Carathéodory et la mesure dans les espaces topologiques”…

  • the Bourbaki code revisited

    The fictitious life of Nicolas Bourbaki remains a source of fascination to some. A few weeks ago, Michael Barany wrote an article for the JStor Daily The mathematical pranksters behind Nicolas Bourbaki. Here’s one of the iconic early Bourbaki pictures, taken at the Dieulefit-meeting in 1938. More than a decade ago I discovered the exact…

  • Map of the Parisian mathematical scene 1933-39

    . Michele Audin has written a book on the history of the Julia seminar (hat tip +Chandan Dalawat via Google+). The “Julia Seminar” was organised between 1933 and 1939, on monday afternoons, in the Darboux lecture hall of the Institut Henri Poincare. After good German tradition, the talks were followed by tea, “aimablement servi par…
