*(About)*

Lecturing has never been an effective teaching technique and now that information is everywhere, some say it's a waste of time. Indeed, physicists have the data to prove it.

2012-01-06 - A Mathematician’s Lament
*(About)*

I don’t see how it’s doing society any good to have its members walking around with vague memories of algebraic formulas and geometric diagrams, and clear memories of hating them. It might do some good, though, to show them something beautiful and give them an opportunity to enjoy being creative, flexible, open-minded

You don’t need to make math interesting— it’s already more interesting than we can handle! And the glory of it is its complete irrelevance to our lives.

Mathematics is the music of reason.

We learn things because they interest us now, not because they might be useful later.

How many students taking literature classes will one day be writers? That is not why we teach literature, nor why students take it. We teach to enlighten everyone, not to train only the future professionals. In any case, the most valuable skill for a scientist or engineer is being able to think creatively and independently. The last thing anyone needs is to be trained.

2009-06-01 - Symmetric matrices related to the Mertens function
*(About)*

In this paper we explore a family of congruences over N* from which a sequence of symmetric matrices related to the Mertens function is built. From the results of numerical experiments we formulate a conjecture, about the growth of the quadratic norm of these matrices, which implies the Riemann hypothesis. This suggests that matrix analysis methods may play a more important role in this classical and difficult problem.

*(About)*

In this paper we explore a class of equivalence relations over N* from which is constructed a sequence of symetric matrices related to the Mertens function. From numerical experimentations we suggest a conjecture, about the growth of the quadratic norm of these matrices, which implies the Riemann hypothesis. This suggests that matrix analysis methods may play a more important part in this classical and difficult problem.
