Maurizio Codogno: un matematto / a madmath.
I got my M.Sc. back in 1986, and then stopped doing "real" mathematics. I still like to solve problems, however; moreover, in all these years I started thinking that maths should be explained in a better way, and people must not think it is just boring calculations (after all, we have pocket calculators now!)
I am Italian, and for me English is mainly a written language - you'd better not hear me say anything in English. If sometimes I write something not really clear, just let me know, I won't be upset at all!
