Mathematical genealogy:

As can be seen here, my mathematical lineage has some noble ancestors (two Bernoulli's, Euler, Lagrange, d'Alambert, Gauss, Hilbert, and others). Maybe this explains my interest in theoretical mechanics! A little bit more detailed genealogy tree is available here, as well as a link to my Math Genealogy page.

Collaboration distance:

Currently, my Erdös number is 5 and my Einstein number is 6.
