"......the average ham can get by with just trig and algebra......" I
dare observe and document that 95% (if not more) of the hams that populate
our local Northern Colorado repeaters are *afraid* of trig and algebra.
They are *totally* illiterate in those very basic subjects. I won't bemoan
that fact further (believe me, I'd love to). 😕😖
My wife and I have a friend who runs a western clothing chain store in
Centenial, Colorado (south of Denver). The store has become #1 in the
nation since she took it over. However, in hiring, she would like to put
the phrase "millenials need not apply" at the very beginning of the
employment advertisements. In short, they don't want to work. I see the
same in my discipline, EMC/RFI and EE in general. The new crop of the
"look-it-up" are about useless.
I really don't want to go on and on, but all this is so true!! My goal in
retirement is to give back much of what I learned in both formal education
and experience on the work place in the hard sciences and math to the newer
high school crowd. I volunteer at the Little Thompson Observatory in
Berthoud, Co and with the STEM program at the HS (see my page on QRZ).
However, now we have a new principal at the school who pontificates "all
subjects are of equal value". Well, you can guess where this goes.
Sporting activities still hold sacred importance above science and math.
After 6 months, we still have yet to talk with her. She avoids us.
Well, all this really isn't relevant to EMC/RFI directly, but Roger's
observations of the present "Google Generation" are so true.
