Re: Impedance &c.



I'm reminded of the matching done to ridiculous effect by the Penny
Farthing Pub we occasionally visit for a Brit. beer and meal.

bc, who notes early in the previous century texts used mechanical
analogues to "explain" electricity, dashpot for resistor, spring
compliance for capacitor, etc. Now it's the reverse.

Happy New Year! The lake is frozen over, and despite the thin layer of
granular remelted snow on its surface, it is skateable, so I will be
out on it later today. It is -10 degrees C here in Burnaby, very cold
for this location. There is much interesting physics to be observed at
this time of year, including my old favorite, the dispersive chirp
heard when a distant hockey stick strikes the ice.

How about a new topic? A list member who read the gyrogenerator series
asked me: "Could you say some more about what you mean by impedance
matched loads?" It happens that I have a great long standing interest
in this topic, so I'm going to try to interest the rest of you.
