Another difference between the world of engineers/physicist and technicians
is
angular frequency (radians per second) and Frequency ( Hertz or cycles per
second).
This manifest itself in different ways, Planck's constant is sometimes h and
others "h bar".
You have to be careful when doing calculations to make sure you use the same
constant.
The oddest thing is that even though scientist seem to prefer angular frequency
they often
switch to wavelength and have to resort correct by 2PI anyway.

It is interesting that in the "Now You're Talking" books from the ARRL, they
tried to
avoid arrows showing direction of current flow in their simple illustrations of
parallel and
series circuits.
I often find myself having to correct myself from time to time when going
from explaining
how electrons flow thru conductors to illustrations of simple circuit analysis.
I grew up in
both worlds.
I have always believed that a good electrical engineer must first be a good
technician.

REPLY:
If there is anything an engineer hates, it is to be wrong. They are paid to
be right and will fight to the death over a concept rather than admit an
error.
