  • writing

    A long time ago Don Passman told me the simple “secret” for writing books : “Get up and, before you do anything else, try to write 2 or 3 pages. If you do this every day, by the end of the year you’ll have a pretty thick book.” Probably the best advice ever for those […]

  • changes

    Tomorrow I’ll give my last class of the semester (year?) so it is about time to think about things to do (such as preparing the courses for the “master program on noncommutative geometry”) and changes to make to this weblog (now that it passed the 25000 mark it is time for something different). In the…

  • Jacobian update 2

    Yesterday a comment was made to the Jacobian update post saying : The newest thing I heard was that the proof unfortunately was incorrect at some point – The jacobian conjecture strikes again..?? Comment by Stefan 12/6/2004 @ 4:16 pm Clearly I was intrigued and I asked for more information but (so far) got no…

  • blog-stress

    What would you do if 80% of your blog is owned by the _companies_ of your Ph.D. students? First, try to talk them into selling some of their blogshares back to the public. If this fails, threaten never to post on your blog again until the share-price has sunk deep enough to force them into…

  • versions e and pi

    Once again, it may take a while before you know why there is a [spooks]-logo next to this message… Thanks so much for the abundant support I received when I mentioned that I might rewrite my 'forgotten' book! There was one (1) comment

  • Scottish solids

    John McKay pointed me to a few interesting links on ‘Platonic’ solids and monstrous moonshine. If you thought that the ancient Greek discovered the five Platonic solids, think again! They may have been the first to give a correct proof of the classification but the regular solids were already known in 2000BC as some neolithic…

  • Jacobian update

    One way to increase the blogshare-value of this site might be to give readers more of what they want. In fact, there is an excellent guide for those who really want to increase traffic on their site called 26 Steps to 15k a Day. A somewhat sobering suggestion is rule S : “Think about what…

  • congrats carolyn

    Rumour has it (see for example here or here) that Carolyn Dean proved the Jacobian conjecture in two variables!!! Melvin Hochster seems to have checked the proof and is convinced it is ok. Here is what he mailed to seminar participants The Jacobian conjecture in the plane has been an open problem since 1939 (Keller).…

  • version pi

    Now that versions 2 and 3 of my abandoned book project noncommutative~geometry@n are being referenced (as suggested) as “forgotten book” (see for example Michel's latest paper) it is perhaps time to consider writing version $\\pi$. I haven't made up my mind what to include in this version so if you had a go at these…

  • on fundamentalism

    Politicians have a tendency to jump on bandwagons. After Theo Van Gogh was murdered by a Dutch-Maroccan there has been a unanimous outcry to tackle 'Muslim Fundamentalists' both in the Netherlands and Belgium. The Belgian interior minister came on television assuring the public that he will shut down all fundamentalist internet sites… His teenage children…
