Widlar's Early Treatise on Semiconductors, so large a file to E-mail,
I put it up on my website so you can download it...

Note fig 1.4, the military convention for current flow!

That's not the "military" convention, that's the "physics" convention.
Ask Hobbs ;-)

The US military, and a couple of the Heald-class trade schools, taught
electron-flow convention. That messed up a lot of people.

I took physics in college, and EE courses simultaneously, and both
used the conventional current flow sign.

At MIT, in the Physics department, I took only Classical Mechanics and
Quantum Physics.

Electromagnetics was under the EE department, as were Germanium
transistors ;-)

Advanced Mechanics (and Strength of Materials) I took under the ME
department (I was in the Honors EE Program and had to take "electives"
as if I were majoring in that department).

And lots of annoying Chemistry classes :-(

But great fun with 5 semesters of Calculus thru tensors.

...Jim Thompson

Only 5 semesters of math? What were you, the layout guy?

Cheers
