Starting a new series of articles on common mode current, RF in the shack, mode conversion, and all those weird balance effects. First part is on definitions of balance: https://t.co/z7ukJsrx1M

@Dr_L_Strickland I've just published a translation of Leibniz's Historia inventionis phosphori, hope it will be of interest to you (and anyone interested in Leibniz and the history of science). https://t.co/RpvZPGJiku

Phosphorus was discovered by distilling many gallons of human urine.
I've now published an English translation of Leibniz's history of phosphorus, "Historia inventionis phosphori" (1710), available on my website:

I got this copy of vol. 1 (of 2) of William of Malmesbury's 12th century history of English kings. Published 1850. Living so large rn

I also have Linus Pauling's General Chemistry. It's not an amazing textbook either, but at least it is lean without the BS colors and photos and Learning Objectives. It trusts its audience and welcomes them to a new complex field. And you wouldn't be thought weird for reading it.

[Sam Gallagher @analog_sam]

Not to be a downer, but this textbook (free from my days at Drexel) is a perfect illustration of everything wrong with modern intro textbooks. So as an appreciator of good textbooks, I'm gonna rant.

[Sam Gallagher @analog_sam]

But why? Why should the textbooks with the widest audience (and they most at risk of becoming disinterested) get such careless, bloated, boring treatment? This is the point where learners should be made to feel capable and welcome to explore a real field.

Working out math stuff on old computer paper is the right vibe for 2026

@markusdd5 @Afghan_Engineer Idk man, BJTs are pretty sweet: Low ON voltage and far less ESD sensitivity, cheap and common in single-device thru-hole pkgs for our breadboarding brethren, and good high freq behavior for us rf nerds, just gotta pay the ib and Vce,sat tax
