Also, how about these:

-Quantum thermodynamics

-Zilog z80 assembly language

-Latin language and knowledge of the classics

-Geography of the Puglia Region in Southern Italy

-Competitive manouvering techniques in sail racing

-Automata theory (advanced postgraduate level)

-Chemo-physical processes in the hardening of steel

-Local search metaheuristics in constrained optimization

-Agent languages for distributed problem solving in multi-agent systems
