Boing!

You might want to think about that sentence for a while.


Let me rephrase. Everything about RMS standing wave
current can be understood simply by superposing the
values of the forward and reflected current phasors
whose phasor length is (usually) represented by their
RMS values.

Better.

As I said, earlier, This thread has drawn me back to re-reading "Zen
and the Art of Motorcycle Maintenance". If you haven't read it, I
highly recommend it.

Here is a passage that jumped out at me, last night.

"The real purpose of scientific method is to make sure
Nature hasn't misled you into thinking you know something
you don't actually know. There's not a mechanic or scientist
or technician alive who hasn't suffered from that one
so much that he's not instinctively on guard.
That's the main reason why so much scientific and mechanical
information sounds so dull and so cautious.
If you get careless or go romanticizing scientific information,
giving it a flourish here and there, Nature will soon
make a complete fool out of you. It does it often enough anyway
even when you don't give it opportunities.
One must be extremely careful and rigidly logical
when dealing with Natu one logical slip and an entire
scientific edifice comes tumbling down. One false deduction
about the machine and you can get hung up indefinitely."
