Well, in the S-plane you toss the damn electrons down the negativ imaginary axis instead of up
the imaginary axis... which is about the same thing as I described... ;O)

Hey! That's it... I allways knew there where something odd about them - they are about the only
laws of nature that actually stink by themselfs! ;O)

Eh... and yes, you can do tube logic without fiddeling with positrons and protons.
