Assuming two concentric tubes, both conductors with a field between them. Does introducing a plastic, say nylon in the field change it in any way? Direction? Field strength? Thanks, Mikek

I was reading this: and was wondering about the objection to robots being "too accurate". [There is a lack of concensus whether or not this is the case -- though I'm sure technology could address that issue] I would think that a batter (and a pitcher) would welcome a repeatable definition of the strike zone to eli

I bought a candy bar that was 91% cocoa. Actually, they had one that was 100% but I chickened out on that. The 91 is too bitter for us to eat. But gently melted with a little heavy cream, it becomes an excellent ice cream sauce. All while my Spice sim is still running at 15 PPM of real time.

Anyone is free to answer, I just wanted Bill look at it. Running tests on the 2"x2"x 34" glass vessel with aluminum tape electrodes on two sides. The emulsion is 23% water and 77% soybean oil. The first test the water was clean, we drain the unit shake the oil to get a new emulsion and repeat the test with some small change and run again, every subsequent test we get nearly the same s

The Keithley 2001 is obsolete, so our test department is moving on to a Keysight. They'll have to add a driver into our Python library. They loaned me one to evaluate. https://www.dropbox.com/scl/fi/vv1u2r1whendlxioihoma/Two_DVMs.jpg?rlkey=y0pbb1xhjl5na4004lfjoih6 c&raw=1 Not too bad, considering that my Fluke hasn't been calibrated in human memory.

I am using the portable charger on friend's house, but it's tripping the GFCI circuit. How is that possible if the vehicle is isolated from the ground with four rubber tires? The 15A power extension is fine. I have used this charger on another house before. Is the GFCI outlet too sensitive? Anyway to deal with this? Temporary bypassing the GFCI outlet?
