  • The $\mathbb{F}_1$ World Seminar

    For some time I knew it was in the making, now they are ready to launch it: The $\mathbb{F}_1$ World Seminar, an online seminar dedicated to the “field with one element”, and its many connections to areas in mathematics such as arithmetic, geometry, representation theory and combinatorics. The organisers are Jaiung Jun, Oliver Lorscheid, Yuri […]

  • Huawei and French mathematics

    Huawei, the Chinese telecom giant, appears to support (and divide) the French mathematical community. I was surprised to see that Laurent Lafforgue’s affiliation recently changed from ‘IHES’ to ‘Huawei’, for example here as one of the organisers of the Lake Como conference on ‘Unifying themes in geometry’. Judging from this short Huawei-clip (in French) he…

  • Bourbaki and Grothendieck-Serre

    This time of year I’m usually in France, or at least I was before Covid. This might explain for my recent obsession with French math YouTube interviews. Today’s first one is about Bourbaki’s golden years, the period between WW2 and 1975. Alain Connes is trying to get some anecdotes from Jean-Pierre Serre, Pierre Cartier, and…

  • the bongcloud attack

    In this neverending pandemic there’s a shortage of stories putting a lasting smile on my face. Here’s one. If you are at all interested in chess, you’ll know by now that some days ago IGMs (that is, international grandmasters for the rest of you) Magnus Carlsen and Hikaru Nakamura opened an official game with a…

  • Teapot supremacy

    No, this is not another timely post about the British Royal family. It’s about Richard Borcherds’ “teapot test” for quantum computers. A lot of money is being thrown at the quantum computing hype, causing people to leave academia for quantum computing firms. A recent example (hitting the press even in Belgium) being the move of…

  • Lockdown reading : Penumbra

    In this series I’ll mention some books I found entertaining, stimulating or comforting during these Corona times. Read them at your own risk. It’s difficult to admit, but Amazon’s blurb lured me into reading Mr. Penumbra’s 24-Hour Bookstore by Robin Sloan: “With irresistible brio and dazzling intelligence, Robin Sloan has crafted a literary adventure story…

  • Lockdown reading : the Carls

    In this series I’ll mention some books I found entertaining, stimulating or comforting during these Corona times. Read them at your own risk. An Absolutely Remarkable Thing (AART for the fans) by Hank Green came out in 2018, and recently I reread it when its sequel A Beautifully Foolish Endeavor appeared last summer. “Protagonist April…

  • G+ recovery 2 : Grothendieck

    My Google+ account is going away on April 2, 2019, so i’ll try to rescue here some posts, in chronological order and around one theme. Here’s Grothendieck-stuff, part two.

  • G+ recovery 1 : Grothendieck

    My Google+ account is going away on April 2, 2019, and all attempts to automatically backup my G+ posts seem to fail so far. So i’ll try to rescue here some of them, in chronological order and around one theme. Today, Grothendieck-stuff, part one. May 30th, 2013 Recordings of a 1972 talk by Grothendieck at…
