Of course math majors forgot how to calculate, they use computer tools for all calculations and they do the creative thinking and problem solving. The senior domain engineers should ask junior engineers who will at least know one tool: the signal processing module in that one commercial software tool that replaces almost all of an electrical engineer. Engineers (with at least one mathematician on the team) can solve problems. But they are people and therefore their calculations are not reliable. They should be used for problem solving, not calculation or any other standards compliance. Whatever standard you wish to impose (like accurate integration computation or capitalization) should be done via automated tools, not by imposition on people. Mike Brenner
