You can see why I chose a career as a scientist rather than as
I've also posted some less frivolous poetry.
Here are three poems I wrote about books by George R.R. Martin.
Here is my translation of Heinrich Heine's poem Die Lorelei.
Here is my translation of Charles Baudelaire's poem Le Gouffre.
And here is one of my favorite poems, by Conrad Aiken, which is virtually unknown. It's very appropriate for an Easter poem, and I'm posting it for Easter 2018.
I gave a talk about Minkowski's and Keller's cube tiling
conjectures, their motivations, and their eventual proof and disproof,
in the IAP Mathematics Lecture Series, on January 26, 2004. The
history of these conjectures is quite interesting, as Minkowski's original
conjecture was motivated by a question about Diophantine approximations,
but on the way to their resolutions, these conjectures mutated into questions
about tiling high dimensional spaces with cubes, about finite Abelian groups,
and about the structures of certain specific graphs.

A good textbook is
Nielsen and Chuang.
Good course notes at the web are available from
Preskill, which may eventually become a book, and from

previously had a link to David Mermin's course notes as well, but these
don't seem to be on the web anymore. They've been turned into
For my recent courses, I have used MIT's Stellar course management system.
