One of the original hallmarks of HP was its "measurement capability". To a hammer, everything looks like a nail. To HP, everything looked measureable. So, whether it was atomic physics, chemical analysis, ink composition, or inventory items, HP engineers (and recall that virtually all salespeople were engineers at the time) thought in terms of measuring quantities of things, sizes of things, rates of change, productivity measures, and so forth. This still prevails, as any deep discussion with Ann Livermore's Services teams will quickly reveal (even the EDS acquisition folk are sometimes heard to talk this way).
Enter "data Visualization". You've all seen, perhaps played, the Flight Simulator software packages, and I'm sure that you're aware that all jet pilots in training now learn in simulators (even the hijackers, training in Miami). No one would send a would-be pilot up in the sky to "shoot touch-and-go" with a new Dreamliner, or even a 747. And, thankfully, no one would demand of an erstwhile pilot that he or she solve the calculus equations of landing safely.
And some pretty cool math packages now exist, for PCs and Macs, and even graphing software for HP and TI handheld calculators. By the way, did you know that the HP-12C functions can be bought for the I-Phone now, for a cool $1?
But, we don't teach "mapping" or "data visualization" or any of these "intuitive" tools until or unless you're a math major, well down the road of arcane statistical analysis. Why not? Why shouldn't these be the tools of junior high school kids, alongside algebra and geometry, etc. These tools will be far more useful for citizenry in the 21st century than trig or calculus. Try that idea on your local school board!
