Yep. A physicist trying to explain a balanced line to other physicists, without knowing the word for it.
Haldane would be spinning in his grave.
Cars from the 60's-70's suck big time.
Sooo true. My first car was a 1976 Buick Century with 231 cc V6 engine, normally aspirated. The engine wasn't half-bad -- this was before emissions controls other than a PCV, EGR and catalytic converters so it *was* simple to work on -- but in every other respect it was dreadful by modern standards. 105 horsepower to move 3800+ pounds equals 0-60 in 17 seconds and 15 miles to the gallon, baby.
But aside from power to weight ratios, the thing which really sucked about old cars was the suspension and handling. Every time I see a car chase in a movie from the 1970s I laugh because I *remember* driving cars like that. By modern standards they cornered like inebriated hippos on roller skates.
If the end of the coil that is hanging is grounded (earthed), it becomes an autotransformer. As it's shown, it's a variable inductor and the disconnected end is irrelevant and has no meaningful physical effect at the frequency a spark transmitter could have reached.
This comment seems to get closer to what they actually mean in their scientific paper. But the article about it is garble and the paper might suffer from second-language issues, and a lack of familiarity with the terms used in RF engineering.
Sorry, I was being sarcastic. I happen have built more than one counterpoise.
The point they're missing is grounding of the "asymmetric" half of the antenna, and that's to keep a static charge from building in the antenna that'll zap through your electronics (or you) for safety reasons.
Sometimes. But you're missing what a Counterpoise does.
Damn, I wish I would have patented that and all its quantum magic...
I noticed that my vertical transmitting antenna often works better if I connect a horizontal wire about the same length as the antenna to ground at its base! The wire isn't connected to the transmitting side of the circuit at all! And how well it works varies depending on the length! Obviously there is some deus ex machina at work here...
Clearly you missed the bit where they invoked quantum mechanics, surely that explains away all the inaccuracies, like the fact you can already buy chip scale dielectric antennas
The thing that I really hate about Innovation Stories is that the reporter invariably doesn't understand what's going on, and invariably is easily convinced that The Obviiously Very Technical People have some very valuable invention.
Marconi's connection to the center tap of a coil with one end not connected worked by broken symmetry? Really? It wasn't just a method of tuning a coil to the correct reactance for a particular frequency?
By that argument why bother excavating garbage pits, when temples and mausoleums are so much sexier? Well, because temples and mausoleums are consciously built by high status people to convey messages. Garbage (and by extension pollution) tell you things about everyone, including things they didn't think worthy of documenting but turn out to be interesting.
OTOH, the real problem is not loans to businesses, but when we make huge tax breaks to monster businesses such oil companies, GM, Ford, etc to take work offshore, rather than keep it here.
Google has been focused on an Autonomous system. That is true. But, so far, no car maker has expressed an interest in it.
As such, there is no reason to believe that they will not consider building their own cars. And if they were to do so, I am guessing that they will Work with Tesla to make their own.
