It used to be the case that one could listen to grandstand’s coverage of the cricket while following along on cricinfo. Now, the ABC blocks anyone with an IP address outside of Australia from listening in. Does anyone in Australia … Continue reading →

The Two Cultures of Mathematics: A Rebuttal

Posted on December 12, 2012 by Persiflage

Gowers writes thoughtfully about combinatorics here, in an essay which references Snow’s famous lectures (or famous amongst mathematicians – I’ve never met anyone else who has ever heard of them). The trouble, however, starts (as it often does) with the … Continue reading →

Hilbert Modular Forms of Partial Weight One, Part II

Posted on December 8, 2012 by Persiflage

Anyone who spends any time thinking about Hilbert modular forms of partial weight one — see part I — should, at some point, wonder whether there actually exist any examples, besides the “trivial” examples arising as inductions of Grossencharacters. Fred … Continue reading →

There are no unramified abelian extensions of Q (almost)

Posted on November 27, 2012 by Persiflage

In my class on modularity, I decided to explain what Wiles’ argument (in the minimal case) would look like for \(\mathrm{GL}(1)/F\). There are two ways one can go with this. On the one hand, one can try to prove (say) … Continue reading →

After twice failing to achieve a 2/3 majority on previous votes, the AMS busted up the filibuster and railroaded through their new fellows program. The initial implementation was based on having achieved one of several things, the easiest of which … Continue reading →

András Schiff Plays Bach

Posted on November 8, 2012 by Persiflage

The first Bach CD I ever bought was András Schiff’s recording of the Well Tempered Clavier. My memory is a little hazy, but I think I paid almost $100 (AUS) for the 4-CD set (I ordered it through Allans Music … Continue reading →

Posted on November 3, 2012 by Persiflage

While on the way to meet up with BF, I stopped by and ordered an 8 ounce latte at the Pig. The result: a foamy scalding hot disaster which brought great shame upon hipster cafes everywhere. It was so bad, … Continue reading →

Posted on October 31, 2012 by Persiflage

I usually manage to avoid having to make any of those annoying calls to banks, credit card companies, utility companies, etc. because DW does it all for me. However, there are times (for example, when things are in my name) … Continue reading →

Schoenberg

Posted on October 28, 2012 by Persiflage

The best show on television…is surely classic arts showcase. It’s RAGE for classical music, by which I mean something like an eclectic classical music version of MTV (during the 80’s). Given the limited range of classical music that makes it … Continue reading →

Jacobi by pure thought

Posted on October 26, 2012 by Persiflage

JB asks whether there is a conceptual proof of Jacobi’s formula: \(\Delta = q \prod_{n=1}^{\infty}(1 – q^n)^{24}\) Here (to me) the best proof is one that requires the least calculation, not necessarily the “easiest.” Here is my attempt. We use … Continue reading →
