CIRCLE WITH A DOT

Grandpa, hanging around in the OEIS helping people to get their stuff in.

Love the history of mathematics, computational mathematics, and reverse engineering. Sometimes translate papers by Euler and Riemann.

I entertain myself with hacking and learning new computer languages.

I wish that TeX and CAS merge into one unity, eliminating any 'formula translating system'.
