Last time we did recall Manin’s comparisons between some approaches to geometry over the absolute point $\pmb{spec}(\mathbb{F}_1)$ and trends in the history of art. In the comments to that post, Javier LopezPena wrote that he and Oliver Lorscheid briefly contemplated the idea of extending Manin’s artsydictionary to all approaches they did draw on their Map… Read more »

No christmas or newyears family party without heated discussions. Often on quite silly topics. For example, which late 19thcentury bookcharacter turned out to be most influential in the 20th century? Dracula, from the 1897 novel by Irish author Bram Stoker or Sir Arthur Conan Doyle’s Sherlock Holmes who made his first appearance in 1887? Well,… Read more »

Terry Tao is reworking some of his better blogposts into a book, to be published by the AMS (here’s a preliminary version of the book “What’s New?”) After some thought, I decided not to transcribe all of my posts from last year (there are 93 of them!), but instead to restrict attention to those articles… Read more »

We will see later that the cyclic subgroup $T_6 \subset \mathbb{F}_{p^6}^* $ is a 2dimensional torus. Take a finite set of polynomials $f_i(x_1,\ldots,x_k) \in \mathbb{F}_p[x_1,\ldots,x_k] $ and consider for every fieldextension $\mathbb{F}_p \subset \mathbb{F}_q $ the set of all ktuples satisfying all these polynomials and call this set $X(\mathbb{F}_q) = { (a_1,\ldots,a_k) \in \mathbb{F}_q^k~:~f_i(a_1,\ldots,a_k) =… Read more »

Yesterday, Jan Stienstra gave a talk at theARTS entitled “Quivers, superpotentials and Dimer Models”. He started off by telling that the talk was based on a paper he put on the arXiv Hypergeometric Systems in two Variables, Quivers, Dimers and Dessins d’Enfants but that he was not going to say a thing about dessins but… Read more »

Just read/glanced through another mathforthemasses book : [The secret life of numbers](http://www.amazon.co.uk/SecretLifeNumbersPiecesMathematicians/dp/0309096588/sr=81/qid=1168541999/ref=sr_1_1/20337767507074362?ie=UTF8&s=books) by [George G. Szpiro](http://www.citebase.org/search?submit=1&author=Szpiro%2C+George+G.). The subtitle made me buy the book : **50 easy pieces on how mathematicians work and think** Could be fun, I thought, certainly after reading the Amazonblurb : Most of us picture mathematicians laboring before a chalkboard, scribbling numbers… Read more »

The CategoryCafe ran an interesting post The history of ncategories claiming that “mathematicians’ histories are largely ‘Royalroadtome’ accounts” To my mind a key difference is the historians’ emphasis in their histories that things could have turned out very differently, while the mathematicians tend to tell a story where we learn how the present has emerged… Read more »

The Klein Four Group is an a capella group from the maths department of Northwestern. Below a link to one of their songs (grabbed from P.P. Cook’s Tangent Space ). Finite Simple Group (of order two) A Klein Four original by Matt Salomone The path of love is never smoothBut mine’s continuous for youYou’re the… Read more »

You don’t know how lucky you are to be able to begin a LaTeXdocument with something like \documentclass[a4]{amsart}. This simple line tells the machine what the size of paper is it has to print to, which part of that paper has to be filled with text, what the design of titles, sections etc. is (and… Read more »

The nerd implimentation of GTD is based on plain textfiles, or more precisely – all lists in text files, kept in directory “~/Documents/txt” – all documents maintained in Markdown for easy HTML conversion I’ve been writing HTMLcode since the times that the best browser around was something called NCSA Mosaic so I’ve never paid too… Read more »

Politicians have a tendency to jump on bandwagons. After Theo Van Gogh was murdered by a DutchMaroccan 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… Read more »

It is always rewarding to prepare a success guaranteed meal for a large group, so we invited all people present at LeTravers at the moment (12) for a sanglierparty on wednesdayevening. Not that there is so much reason to party given the outcome of the USelections. It is an insult to the rest of the… Read more »

One week to go before the regional and European elections and tension is rising. For me there are two crucial questions : will a racist party get more than 20% of the votes? and will the green party get over the electoral threshold of 5%? If you are not Flemish both probably require some explanation…. Read more »

We still have an original iMac (Bondi Blue). It runs at 233 MHz, has 192Mb RAM and a harddisk of 4Gb, so is pretty outdated. Still, when Mac OSX was introduced I had a hard time installing extra RAM in it (for this model you have to take it apart disconnecting all sorts of cables)… Read more »
