You folks are
all young sprouts... when I was in H.S. (1938) our AV
equipment was a wind up phonograph (disks, not cylinders,) and a lantern
slide projector. Once someone from Bell Telephone brought in a movie
projector and showed films! Calculations? they were done with a pencil on
"foolscap". And no, I didn't have Socrates for a teacher.
I went through HS on a slide rule. Someone brought in an electromechanical
^^^^^^^^^^
calculator to my math class, and I fell in love with
it. <sigh>
You know, I think my generation was the last to learn about using
the slide rule in highschool (I graduated in 1979). In 1975, when I
was a freshman, all students in my school were requied to learn
it; it was part of the ISM (Intro.to Sci. Method) program which all
students had to pass in order to graduate.
When asked "WHY?", school administrators had a plausible answer: "It
teaches you how to read scales and graduations commonly found on lab
equipment."
OK, fair enough. Of course, nowadays I imagine most of the
analytical balances in use are digital . . .
