Luis Sánchez, currently an undergraduate physics student at Universidad de Guadalajara. My current research is in the area of interstellar molecular clouds (where star formation takes place) under the direction of Susana Lizano (at CRyA), we have preliminary results of the analytic expression that governs the photon flux in ionized regions with density gradients.

You can follow my adventures here.

Luis, receive this little award for your efforts to take afar the name of the U de G abroad:

[edit] A little challenge

A quite remarkable expresion that was a discovered by a young mathematician (at age 14!!) is

\sum_{n=1}^{\infty}n^{-n}=\int_0^1 x^{-x} \ dx

I am not posting the identity of this young mathematician as it will make the problem at reach within google. The first one to post a demostration here will have some little reward (that I still have to decide!). You don't need any fancy technique, just a bit of cleverness.

    • luis, can you give me the address? In altre hand, hier we did exam...ples, could you conctact me, pleasee?--kiddo 17:50, 7 December 2006 (UTC)
