e KOh, I'm all set up to do that. (testing diode thermometers) Here's a link...(Image shack now wants me to register, so that's the end of that.)
I could only get to 10mA. (The most my current source will do.) So not into the ohmic region. The straight line is drawn by eye.

Oh I forgot to add that at 10mA the diode was heating up and the forward voltage dropping, so the 725 mV number was the first thing the DMM registered... and readings went down from there.

Grin... Pulsing is beyond my test setup. But last time I looked at these I subtracted the adjacent numbers (112.24, 112.79 and 118.78 for the largest three,) and then atributed the difference in the last one (6mV) to the resistance. 0.6 ohms in this case.

I'd consider whining to be high pitched and whinging moderate to low pitched so it's closer to grumbling or moaning than to whining.

One wonders about that. Looking through history, the more brilliant someone is, the more likely they're crazy.

Of course. Ideas come from permeability in the barriers that segrate ideas and brain functions. Schitzophrenia comes from a more complete breakdown.
I guess attachment to reality works the same way. If you can reasonably suspend conventional concepts of what's possible and impossible, you can better explore the solution space. If you suspend all limits on the possible, you become a loonie.
Here's another interesting relationship: the more politically powerful a person is, the more likely that they are sociopaths.

Yep. Actually, that double curve reminds me that, if you do that for IB _and_ IC of a _transistor_, you can derive all kinds of model parameters. I did that, with assistance from my son Aaron, in the early '80's writing the solution of that problem as a Pascal executable. (Damn! I thought nothing of it then, but Aaron was only
12 years old at the time! He's gone on to be in charge of all software creation and utilization for the world's largest call-center corporation... working from his farm house in San Tan Valley, AZ :-) ...Jim Thompson

Profound observation.
May I add?:
The more "god-fearing" a person, the greater likelihood of a sociopath.
