>>teacher decided to force logs on us... by way of a slide rule. Back in the dark ages, my HS physics & chemistry instructors had us do the formulae with sliderules for weeks before we got to bring in our fancy pricey scientific calculators (HP-25c is 1976). This was NOT to push logarithms on us but to push Scientific notation, ESTIMATION and dimensional analysis. Why? Since the exponent or decimal point is done in wetware while the slipstick tracks the mantissa, one must understand what you're doing to get the right answer. So when we started punching buttons, we had a better chance to get the right answer there too.
A good sliderule still does rectangular to polar conversion, or proportions, quicker and simpler than any digital device ... -- Bill n1...@arrl.net bill.n1...@gmail.com _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
