...so I was *actually* trying to figure out what impedence matching is,
but instead I ended up reading a fascinating article about nomography.
Wikipedia is like that...

Very interesting, I never thought about how you could do all that
graphically, a shame really, that's so much prettier than a calculator.

Hehe don't start the whole voltage/current/complex resistance thing again
;-)

I think it's a nice way of demonstrating that if some variables have a
mathematical relationship, that relationship works in more than one
direction. A formula or an equation doens't demonstrate that quite so
vividly. But drawing three lines and saying "mark two points and draw a
line and you can always find the third point" makes it quite clear.

Well, I ended up staring at a Smith chart - and, obviously, wondering
WTF is going on! And *that's* when I started reading about nomograms...

Yeah, it's good stuff, eh?
Right now I'm wondering... could I draw a chart that allows me to
quickly read off how long an animation will take to render given how
many frames there are and how long each frame takes?
[In principle it's a simple calculation. Except that most of us have no
idea how long "5,000 seconds" actually is. Damned non-metric time
systems! ;-) ]
I'm guessing that since this is a multiplication question, you'd need
logarithmic scales...
