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 eprints, spanning mathematics, physics, computer science, and statistics’ posted on the arXiv. One possible use is to explore the popularity… Read more »

Last time we’ve seen that on June 3rd 1939, the very day of the Bourbaki wedding, Malraux’ movie ‘L’espoir’ had its first (private) viewing, and we mused whether Weil’s wedding card was a coded invitation to that event. But, there’s another plausible explanation why the Bourbaki wedding might have been scheduled for June 3rd :… Read more »

Sunday january 2nd around 18hr NeBstats went crazy. Referrals clarified that the post ‘What is the knot associated to a prime?’ was picked up at Reddit/math and remained nr.1 for about a day. Now, the dust has settled, so let’s learn from the experience. A Redditmention is to a blog what doping is to a… Read more »

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 hardwareupgrades of ‘the Matrix’ (the webserver hosting it), more themes than I care to remember, and a… 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 »

Via Tanya Khovanova I learned yesterday of the 50 best math blogs for mathmajors list by OnlineDegree.net. Tanya’s blog got in 2nd (congrats!) and most of the blogs I sort of follow made it to the list : the ncategory cafe (5), not even wrong (6), Gowers (12), Tao (13), good math bad math (14),… Read more »

Early 1936, Andre Weil and Evelyne Gillet made a prehoneymooning trip to Spain and visited El Escorial. Weil was so taken by the place that he planned the next Bourbakiconference to be held in a nearby college. However, the Bourbakis never made it to to Spain that summer as the Spanish Civil War broke out… Read more »

Next time you visit your mathlibrary, please have a look whether these books are still on the shelves : Michiel Hazewinkel‘s Formal groups and applications, William Fulton’s and Serge Lange’s RiemannRoch algebra and Donald Knutson’s lambdarings and the representation theory of the symmetric group. I wouldn’t be surprised if one or more of these books… Read more »

A few days before Halloween, Norbert Dufourcq (who died december 17th 1990…), sent me a comment, containing lots of useful information, hinting I did get it wrong about the church of the Bourbali wedding in the previous post. Norbert Dufourcq, an organist and student of Andre Machall, the organistincharge at the SaintGermaindesPrés church in 1939,… Read more »

I’m pretty certain I got the intended date & time of the BourbakiPétard wedding right : June 3rd 1939 at 12h. Finding the exact location of the weddingceremony is an entirely different matter. And, quite probably, we are reading way too much in these pranks of the Weilclan. Still, it’s fun trying to find an… Read more »

Among the items found on Andre Weil at the time of his arrest was “a packet of calling cards belonging to Nicolas Bourbaki, member of the Royal Academy of Poldavia”. But then, where is the Royal Poldavian Academy situated? Well, surely in the Kingdom of Poldavia, which is a very strange country indeed, its currency… Read more »

Bloomsday has a tradition of bringing drastic changes to this blog. Two years ago, it signaled a bloomsdayending to the original neverendingbooks, giving birth (at least for a couple of months) to MoonshineMath. Last year, the bloomsday 2 post was the first of several ‘conceptual’ blog proposals, voicing my conviction that a mathblog can only… Read more »

Last time I promised to come back explaining how to setup LaTeXsupport, figuring I had to tell you about a few modifications I had to make in order to get Latexrender run on my mac… A few google searches made it plain how out of touch I am on these matters (details below). But first,… Read more »

“Lieven le Bruyn’s NEVERENDINGBOOKS isn’t really a blog at all…” Vlorbik’s unintentional [smack in the face](http://vlorbik.wordpress.com/2009/02/05/kissjoyasitflies $ left me bewildered ever since. There aren’t that many [mathematical blogs](http://wwwirma.ustrasbg.fr/article817.html) around, and, sure enough, we all have a different temperament, and hence a distinct style. I have no definition of what a mathematical blog should (or should… Read more »

A comment to Charles Siegel’s ‘big theorems’series got me checking my stats.

The algebraic fundamental group of a scheme gives the MazurKapranovReznikov dictionary between primes in number fields and knots in 3manifolds.

We use Kontsevich’s idea of thin varieties to define complexified varieties over F\_un.

Thanks for clicking through… I guess. If nothing else, it shows that just as much as the stock market is fueled by greed, mathematical reasearch is driven by frustration (or the pleasure gained from knowing others to be frustrated). I did spend the better part of the day doing a lengthy, if not laborious, calculation,… Read more »

The black&white psychedelic picture on the left of a tessellation of the hyperbolic upperhalfplane, was called the Dedekind tessellation in this post, following the reference given by John Stillwell in his excellent paper Modular Miracles, The American Mathematical Monthly, 108 (2001) 7076. But is this correct terminology? Nobody else uses it apparently. So, let’s try… Read more »

Often, one can appreciate the answer to a problem only after having spend some time trying to solve it, and having failed … pathetically. When someone with a trackrecord of coming up with surprising mathematical tidbits like John McKay sends me a mystery message claiming to contain “The secret of Monstrous Moonshine and the universe”,… Read more »

There seems to be a slight chance that the next USadministration may (finally) be joining the rest of the civilized world and sign the Kyototreaty.

When more than 200.000 websites are using google analytics, a oneman action proposed last time to deactivate GA on neverendingbooks is pretty useless. Perhaps a better alternative is : When you use google analytics on your site, announce this and add a link to CustomizeGoogle BLOCK GOOGLE ANALYTICS COOKIES. Your visitors can then decide whether… Read more »

Ever since my accidental ‘discovery’ of the word CEILIDH written on a numb3rs blackboard, I keep an eye on their blackboards whenever I watch a new episode, and try to detect terms I might know. Here’s todays screenshot I had to choose one frame from a minute long shot (the ‘link’ on the left hand… Read more »

Google analytics is collecting data on this site for over a month now. Perhaps it is time to share a few lessons Ive learned over this period.
