Dear Steven, Your comments on Grothendieck in the Guardian are very good! I like your sculpture too.

From the early 20th century comes the mathematical theory of topology. Grothendieck’s toposes provide a vastly more general and unifying notion of what topological spaces could be, and he provocatively named them “toposes” as those things of which topology was the study. Or ought to be. Even now, topologists have generally not caught up with him. I wonder if much his later reclusiveness came out of disappointment at the failure of others to understand his ideas." That final paragraph is mere speculation on my part, as I never knew him. Perhaps others on the list have better insights into that. For your amusement, I've attached a ceramic model of his head, which I made when my wife took me on a clay modelling course.
