Me too, but that has its limits. Quantum mechanics,

Aaaaargh! My least favorite subject. I couldn't grab a hold of those
little mothers ;-)

Sorry. Heisenberg figured it out. You can see them, but not touch
(measure) them. Or, you can touch them (measure), but not see them.

You'll just love quantum computing, where a bit (err... qubit) can be
either a zero, one, or both at the same time. No, it's not like
latchup.

It has great potential in cryptography, which is the art of turning
perfectly good data into useless garbage and back again.

Actually, I think I accidentally invented a quantum computing logic
gate. In addition to the usual AND and OR gates, I designed an IF
gate. The logic was "If I feel like, I will. Otherwise, I won't". I
thought of patenting the IF gate design but never bothered.

I think circuit design is like a foreign language... I can think
circuit design in my head ;-)

I used to have the same problem when I did design. I would wake up in
the middle of the night with some great insight, scribble something on
a handy note pad, and wonder what the hell I was thinking the next
morning. However, I never even tried to design anything in my head. I
had to scribble it down. Unfortunately, that was often the table
cloth, newspaper, magazine, blackboard, back of the envelope, etc.
Same with the math. I just couldn't do it in my head. Predictably,
my desk was a mess of scribbled notes. Sample:

That also caused some interesting problems for me. My boss could look
at a tabular list of recorded data from some lab test and determine a
trend directly from the data. I couldn't do that. I had to draw a
graph to see what it looked like and where it was going.

Strangly, when it came to doing RF impedance matching, it was the
other way. I prefered to do it the long way, grinding the equations.
I never did bother to use a graphical Smith Chart solution.

Ok, so I'm weird.
