Arlo is great. He's funny, curious, self-effacing, and you can tell he really likes people of both polarities, all of which have kept him from being a big popular success. His movie "Alice's Restaurant" is wonderful.
So many pop musicians have been blatant misogynists. It seems to sell records.
That depends on which sort of negative resistor you are talking about. There are two types. Both obey Ohms law but they are very different creatures. Both can be used to cancel out the real resistance in an RLC tuned circuit.
That reminds me of a tale about a number of University Computer Science professors being asked whether they'd be willing to travel in an aircraft whose flight software had been written by their students.
All except one said "No way".
When the stand out was challenged on his reasoning he said "It's because I'm quite sure it won't get off the ground in the first place."
--- You're probably miffed because Phil knocked you off as a troll and you're trying to undo his commentary with a single 'slyish' denigration but, regardless of his outrageous style, Phil participates in civil debate when it's not nonsensical and he is, as far as I'm concerned, a very welcome, very valuable technical contributor to these groups.
These groups _are_ bastions of civilized debate, but that doesn't mean some of us won't cut you off at the knees if you're a smartass and you make a mistake you won't own up to.
So far, for some reason unknown to me, you seem to have taken an adversarial stance with regard to posts that I've made about negative resistances.
In particular, you've chosen to show disdain for my work without even extending the courtesy of examining it which is, at best, foolish.
If you want to fight, go for it, but expect no quarter just because you're female.
I'm about to conclude that Sylvia is just a female rendition of AlwaysWrong... either obstinate to the point of ignorance or a troll.
If she continues to exhibit a closed mind I'll write her off.

A lot of our VME modules (say, half of our production) goes into test stands for FADECS, "full authority" jet engine control computers. They test the hell out of them, simulating all the sensors and actuators, normal and failed, running scripts that take days to execute, and generate feet of paper reports. If they change a tiny bit of code, they run it all again. That's cool, because they can never take down a test stand, so we're always supplying new modules.
"Full Authority" means no mechanical or hydraulic backups. Code fails, plane falls.
John L & Sylvia... sounds like a '60's rock group ;-)

If you "can't be bothered" why are you persisting in this thread?
Too ignorant, yet too obstinate to listen to your peers?

Well, to me a proper negative resistor is one that has zero current when shorted. Its I vs E curve is just the same as a real resistor of the same absolute value, but the current sign is flipped. It obeys Ohm's law in all quadrants, in all situations.
The nice thing about this resistor is that you can plug its negative value into all the classic equations... series and paralleled resistors, voltage dividers, capacitor rc exponentials, rlc resonators, whatever... and the equations still describe what you'll simulate or measure, small-signal or large.
This is also what LT Spice will do if you assign a negative value to a resistor.
What's the mathematical definition of the other type?
