Also perhaps units conventions etc may be different in EE and Physics, like use of Gaussian units in electrodynamics in Physics, and also things like the mysterious 'Z'-transform that seems to pervade much of EE.

Gaussian units seem to be on their way out. I, for one, won't miss them. (Or cgs.)

The Z-transform is much more related to the others than is clear at first glance. This post on transforms [0] from the The n-Category Café is fascinating, and my go-to for understanding what the Laplace transform really is, even if I don't quite grasp many things in the post. (And I also have a math degree! But not a graduate one in active use, as most of the people around there do.)

> the Laplace transform is really just a generalization of the familiar Laurent series representation of complex analytic functions, but where the exponents are allowed to be non-integers and to “vary continuously” rather than discretely.

I understand some of these words... they're very familiar to me...

I'm saying this as someone who's dealt with the discrete and continuous time Fourier transforms, and Z-transform, and wants to get into Laplace transforms.

it might as well be from a random text gwnerator

Gaussian units make physics prettier.

“Avoid for new designs”

Only now I had noticed, in the Gaussian system, the unit for capacitance is centimeters.
Exactly. Quick now, how many farads in a cm?
