ORIGINAL: DesFIP My stepson just graduated college as a mechanical engineer and his starting salary is $65,000 a year. You know what? He doesn't do math with a pencil and paper. He uses a computer program to try to solve the engineering problems his company is dealing with. His entire team uses computers for this, not a graphing calculator, not a slide rule, and not a pencil and paper. And no, he doesn't ask if they want fries. Go call up the nearest math type company in your area and ask the HR person is the actuary in the insurance company figures out the statistics by hand or on a computer. Ask the public accounting firm that same question. Ask a structural engineer if when his firm is working on a new bridge whether they do it by hand or on a computer. I already know the answer, sounds like you don't. Let me present an analogy. I have been a practicing molecular biologist/geneticist for over two decades now. There were many techniques which were particularly labour-intensive when I was younger, and which are now easily taken care of by commercially available kits. Now, I frequently get new undergrad and grad students who have only ever used these kits; when something goes wrong, these students are often stymied, with no real idea as to how they should set about troubleshooting the technique, simply because they lack sufficient knowledge of the underlying principles. And that's largely what I'm arguing in favour of, enough of a grounding in basic skills, such that even if an individual is no longer using those skills on a day-to-day basis, he/she can understand or challenge data/claims/techniques purportedly based on those skills from first principles. Back in 1988, John Paulos wrote a cute little book called Innumeracy: Mathematical Illiteracy and Its Consequences in which he both railed against math illiteracy and pointed out how it is taken advantage of to hoodwink the masses. I don't think arming people with digital calculators or computers has changed the situation since then. As for your stepson, no one is suggesting that he not use a computer for his engineering projects. But I'd be very surprised if he can't solve say, simple stress-load problems, using back-of-the-envelope calculations. Any engineer worth his/her salt can.
