    Grothendieck’s gallery No. 154

    Posted on by

    Since mid May the Montpellier part of Grothendieck’s gribouillis are online and for everyone available at the Archives Grothendieck. The story is well-known. End of June 1990, Grothendieck phoned Jean Malgoire warning him to come asap if he wanted to safeguard the better part of G’s mathematical archive, for he was making a bonfire… A… Read more »

    Ulysses and LaTeX

    Posted on by

    If you’re a mathematician chances are that your text-editor of choice will be TeXShop, the perfect environment for writing papers. Even when writing a massive textbook, most of us stick to this or a similar LaTeX-frontend. The order of chapters in such a book is usually self-evident, and it is enough to use one TeX-file… Read more »

    Grothendieck’s gribouillis

    Posted on by

    A math-story well worth following in 2015. What will happen to Grothendieck’s unpublished notes, or as he preferred, his “gribouillis” (scribbles)? Here’s the little I know about this: 1. The Mormoiron scribbles During the 80ties Grothendieck lived in ‘Les Aumettes’ in Mormoiron In 1991, just before he moved to the Pyrenees he burned almost all… Read more »

    bookworm arXiv

    Posted on by

    One of the nicer tools around is bookworm arXiv which ‘is a collaboration between the Harvard Cultural Observatory, arxiv.org, and the Open Science Data Cloud. It enables you to explore lexical trends in over 700,000 e-prints, spanning mathematics, physics, computer science, and statistics’ posted on the arXiv. One possible use is to explore the popularity… Read more »

    the matrix reloaded

    Posted on by

    The dinosaurs among you may remember that before this blog we had the ‘na&g-forum’ to accompany our master-class in noncommutative algebra & geometry. That forum ran on an early flat-panel iMac G4 which was, for lack of a better name, baptized ‘the matrix’. The original matrix did survive the unification of the three Antwerp universities… Read more »

    wp-latex’ sweet revenge : wp+MathJax-> ePub

    Posted on by

    In the early days of math-blogging, one was happy to get LaTeXRender working. Some years later, the majority of math-blogs were using the, more user-friendly, wp-latex plugin to turn LaTeX-code into png-images. Today, everyone uses MathJax which works with modern CSS and web fonts instead of equation images, so equations scale with surrounding text at…

    From WordPress to ePublishing (1)

    Posted on by

    Perhaps, the tips and tricks I did receive to turn a selection of wordpress-posts into a proper ePub-file may be of use to others, so I will describe the procedure here in some detail. It makes a difference whether or not some of the posts contain TeX. This time, I’ll sketch the process for non-LaTeX… Read more »

    eBook ‘geometry and the absolute point’ v0.1

    Posted on by

    In preparing for next year’s ‘seminar noncommutative geometry’ I’ve converted about 30 posts to LaTeX, centering loosely around the topics students have asked me to cover : noncommutative geometry, the absolute point (aka the field with one element), and their relation to the Riemann hypothesis. The idea being to edit these posts thoroughly, add much… Read more »

    Mathblogging.org is a recent initiative and may well become the default starting place to check on the status of the mathematical blogosphere. Handy, if you want to (re)populate your RSS-aggregator with interesting mathematical blogs, is their graphical presentation of (nearly) all math-blogs ordered by type : group blogs, individual researchers, teachers and educators, journalistic writers,… Read more »

    NeB : 7 years and now an iPad App

    Posted on by

    Exactly 7 years ago I wrote my first post. This blog wasn’t called NeB yet and it used pMachine, a then free blogging tool (later transformed into expression engine), rather than WordPress. Over the years NeB survived three hardware-upgrades of ‘the Matrix’ (the webserver hosting it), more themes than I care to remember, and a… Read more »

    Lists 2010 : StackExchange sites

    Posted on by

    One of the trends of 2010 was the proliferation of StackExchange sites. I guess by now most of us visit MathOverflow along with the arXiv daily. But, there are plenty of other StackExchange sites around that may be of interest to the mathematics-community : Mathematics somewhat less high-brow than MathO. Physics still in the beta-phase… Read more »

    Jason & David, the Ninja warriors of noncommutative geometry

    Posted on by

    SocialMention gives a rather accurate picture of the web-buzz on a specific topic. For this reason I check it irregularly to know what’s going on in noncommutative geometry, at least web-wise. Yesterday, I noticed two new kids on the block : Jason and David. Their blogs have (so far ) 44 resp. 27 posts, this… Read more »

    Books Ngram for your upcoming parties

    No christmas- or new-years family party without heated discussions. Often on quite silly topics. For example, which late 19th-century 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 »

    Link problems : Markdown versus latex2wp.py

    Posted on by

    As John Baez (and hopefully others) noticed most links here on NeB are now screwed up. For years I’ve used the Markdown syntax to include links in posts (that is something like [this is what you see](and here is the URL)). NeB used an older version ( Version 1.0.1k) of php Markdown to convert these… Read more »

    Return to LaTeX

    Posted on by

    To most mathematicians, a good LaTeX-frontend (such as TeXShop for Mac-users) is the crucial tool to get the work done. We use it to draft ideas, write papers and courses, or even to take notes during lectures. However, after six years of blogging, my own LaTeX-routine became rusty. I rarely open a new tex-document, and… Read more »
