Help
In college in the 1960's I discovered that I have a knack for helping people understand technical ideas, and I have used this talent ever since in many contexts, from modeling biological systems using mathematics, to doing research and development in the telecommunications software industry, to tutoring kids and adults in math, to teaching math part-time at several high schools.
