## Seriously now, where was the Bourbaki wedding?

Posted on by

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 organist-in-charge at the Saint-Germain-des-Prés church in 1939,… Read more »

## Grothendieck’s functor of points

A comment-thread well worth following while on vacation was Algebraic Geometry without Prime Ideals at the Secret Blogging Seminar. Peter Woit became lyric about it : My nomination for the all-time highest quality discussion ever held in a blog comment section goes to the comments on this posting at Secret Blogging Seminar, where several of… Read more »

After a difficult time for us all, PD1 tells me she finally ‘found her drive’ again : she hopes to finish her 2nd(!) master in fine arts this year as well as her teaching-diplome. Besides, she teaches evening arts-classes twice a week, organizes exhibitions, enters competitions, wins prizes … Looking at the time-stamps on her… Read more »

## return of the cat ceilidh

I couldn’t believe my eyes. I was watching an episode of numb3rs, ‘undercurrents’ to be precise, and there it was, circled in the middle of the blackboard, CEILIDH, together with some of the key-exchange maps around it… Only, the plot doesn’t involve any tori-crypto… okay, there is an I-Ching-coded-tattoo which turns out to be a… Read more »

## 44 32’28.29″N, 4 05’08.61″E

Twenty five years ago I was amazed that writing merely “Le Travers,Sablieres,France” on an envelop did the job. Today I’m even more surprised that typing just “Le Travers,Sablieres” into Google Maps or Google earth brings you there in seconds with an offset of about 100 meters! Actually, the Google mark may be more accurate as… Read more »

## way too ambitious

Posted on by

Student-evaluation sneak preview : I am friendly and extremely helpful but have a somewhat chaotic teaching style and am way too ambitious as regards content… I was about to deny vehemently all assertions (except for the chaotic bit) but may have to change my mind after reading this report on Mark Rowan’s book ‘Symmetry and… Read more »

## attention-span : one chat line

Never spend so much time on teaching than this semester and never felt so depressed afterwards. The final test for the first year course on grouptheory (60 hrs. going from nothing to Jordan-Holder and the Sylow theorems) included the following question : Question : For a subgroup $H \subset G$ define the normalizer to… Read more »

## mathematics & unhappiness

Sociologists are a constant source of enlightenment as CNN keeps reminding Kids who are turned off by math often say they don’t enjoy it, they aren’t good at it and they see little point in it. Who knew that could be a formula for success? The nations with the best scores have the least happy,… Read more »

## Krull & Paris

Posted on by

The Category-Cafe ran an interesting post The history of n-categories claiming that “mathematicians’ histories are largely ‘Royal-road-to-me’ 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 »

## teaching mathematics

Posted on by

Tracking an email address from a subscribers’ list to the local news bulletin of a tiny village somewhere in the French mountains, I ended up at the Maths department of Wellington College. There I found the following partial explanation as to why I find it increasingly difficult to convey mathematics to students (needless to say… Read more »

## micro-sudoku

One cannot fight fashion… Following ones own research interest is a pretty frustrating activity. Not only does it take forever to get a paper refereed but then you have to motivate why you do these things and what their relevance is to other subjects. On the other hand, following fashion seems to be motivation enough… Read more »

As there is no way to recover from the previous post, allow me a slow restart by listing some of the a-typical things done this week : Ate more chocolate than during the last five years Drove the car more than during the rest of the year (minus vacations) Didn't do any bicycle exercise Only… Read more »

Here’s a part of yesterday’s post by bitch ph.d. : But first of all I have to figure out what the hell I’m going to teach my graduate students this semester, and really more to the point, what I am not going to bother to try to cram into this class just because it’s my… Read more »

## NOG master class update

Posted on by

Yesterday I made a preliminary program for the first two months of the masterclass non-commutative geometry. It is likely that the program will still undergo changes as at the moment I included only the mini-courses given by Bernhard Keller and Markus Reineke but several other people have already agreed to come and give a talk….
