Grothendieck, a genius

I’ve written about Grothendieck here before, through two books about this mathematical genius published shortly after his death: Alexandre Grothendieck, 1928 – 2014. Summer is an opportunity for listening to radio broadcasts and I had the pleasure to rediscover this extraordinary character, first of all through Alexandre Grothendieck : un mathématicien qui prit la tangente […]

Alexander Grothendieck, 1928 – 2014

What link is there between Andrew Grove (the previous article) and Alexandre Grothendieck? Beyond their common initials, a similar youth – both were born in the communist Eastern Europe they left for a career in the West) and the fact they have become icons of their world, they just represent my two professional passions: startups […]

Read Jón Kalman Stefánsson without any hesitation

I have already written in a recent post all the happiness that the discovery of Jón Kalman Stefánsson and in particular his Romanesque Trilogy had brought me. Himnaríki og helvíti (2007) / Heaven and Hell (MacLehose Press, 2010) Harmur englanna (2009) / The Sorrow of Angels (MacLehose Press, 2013) Hjarta mannsins (2011) / The Heart […]

Mathematica by David Bessis – about logic and intuition

“Mathematicians are the humans who advance human understanding of mathematics.” William P. Thurston I had already mentioned David Bessis’ book, Mathematica, when the author appeared on France Culture. He had spoken of Grothendieck, but said above all that between logic and intuition, he gave more importance to the second to do mathematics. Go back to […]

Doris Lessing again – about great men

I wrote in Testament or Testimony ? Lessing, Reich, Grothendieck, Jobs, Arles how much I loved reading The golden notebook. I just read another strange page which stroke me. And even more strangely, I discovered that the French translation (that I first discovered) was quite different from the original version. Have a look here at […]

Ideas of Geniuses (Idées de génies) by Etienne Klein and Gautier Depambour

From time to time, I blog about science and mathematics. Here is a new example. I just discovered a little wonder of popular science, at the same time simple, luminous and demanding. Ideas of geniuses, (Idées de génies) subtitled “33 texts which have shaken up physics”, by Etienne Klein and Gautier Depambour. Etienne Klein is […]

Mathematics again: Unexpected, Inevitable and Economical

“La libertad es como un número primo.” Roberto Bolaño, Los Detectives Salvajes Michael Harris’ mathematics without apologies, I said it elsewhere, is a must-read if you are interested in mathematics. And probably even more, if you are not. But again, it is not an easy reading. After the claim in his Chapter 3 that mathematics […]

Something rotten in the Google republic?

I should have added a point of disagreement or discomfort in the analysis made by the authors of How Google Works. On page 125, there is a short section called Disproportionate rewards: “Once you get your smart creatives on board, you need to pay them. Exceptional people deserve exceptional pay. Here again you can look […]
