MS in electrical and electronic engineering. Old school guy using j in stead of i in complex analysis and I hate when somebody asks a simple question and uses a lot of symbols to tell us that x is an element in the set of real numbers and n is an element in the set of positive integers, and so on, when it is already completely obvious from the context. Don't like rings and fields and manifolds and other devilish high-brow things but sticks to applied math for solving various problems in physics - including inventing new crazy problems from time to time. Pretty good in solving all kinds of differential- and difference equations, series expansions and integrals and use of numerical methods. Dabs in probability theory and stochastic processes. Otherwise interested in many fields ranging from astronomy to relativity theory. But please don't ask me about quarks and leptons or anything related to chemistry.
