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.

Is there anyone you haven't killfiled, old man?

I

He's killfiled me several times. And then he cheats.

Often useful for tran' sisters. Not necessarily good for engineers.

Well, then I think Ratso is 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.

Not 1N4148 per se, but silicon in general. news:r1u7j79mdi2c4g5bdtpcap7f1oopccrkup@4ax.com From Motorola's 1980 silicon rectifier data manual.

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.

You have that entirely backwards. Read this:

The people that have to write propaganda to tell the rest of us "who 'really' care" are inevitably the ones who care the least - except perhaps feathering their own nests...

The most vociferous champions or detractors, of a cause or issue, often turn out to be the very people who adopt the opposite tack in their own lives.

If you have to brag about how charitable you are, that is just your way of dealing with the guilt you feel. Likewise, if you feel the need to keep score...

Freely give to those who are deserving, then forget about it; anything else is just to bolster your ego or assuage your guilt.

The book was written by a leftists statistician who started his project assuming what you assumed. He found that he was wrong. The book is extensively referenced. You, like many people, define stuff to be "propaganda" because it potentially disturbs your prejudices... so you don't read it.

This book has affected my life, in that I give away more money now than I used to.

Read the book, then we can discuss it.

Wrong yet again.

Interesting side effect of religious indoctrination maybe.

Passive, content, non-confrontational, destiny is controlled by others, etc.,

or in other words.... there is a damn good reason the religiously inculcated are referred to as sheep, and their masters shepherds.

This is the best of all possible worlds. You can do no better. Look no further. Don't rock the boat. Stay inside the box. Comfort is more important than living if the latter involves pain. Go along to get along. You'll be rewarded after you die.
