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.

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.

Why don't the automakers just seek refuge under the DMCA from all those evil automobile hackers? Clearly, figuring out how your car works is a direct attack on the very hard work and property of those automakers.

Time to pass a bill state by state. I'm the sure the invisible hand of the free market will line all the right politicians' pockets to rush those through. Hopefully someday we won't be able to own our cars and we can go back to the Ma Bell days when every phone was rented.

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?

Am I the only one having problems parsing that headline?

Sure, why not? There comes a point where an individual is so dangerous and destructive that a society cannot contain the violence they unleash at every opportunity. Life in prison merely changes the population exposed to that individual. Prison guards, staff, and other prisoners deserve protection from such uncontrollably violent people just as much as anyone else. Capital punishment reduces recidivism rates to zero. No one who has been executed has ever been found to continue committing crimes.

Probably because of the psychological damage to the individual(s) pulling the trigger.

It's only cheaper because our capital punishment process is so badly broken. It should not take decades to complete the process; that's just dumb. On the other hand, there are flaw in how it's applied currently (moving to the second part of your issue with it), so those also need to be fixed. I support the death penalty, but with some pretty major reforms. And as a strong advocate of it, I would be open to suspending it until said reform has changed the process to one which is much faster, cheaper, more humane, more fair, more evidence-based, and more regulated. For starters, take all the stuff the Innocence Project is doing and integrate it directly into the process and provide wide open access to all information going into the process to any third-party groups wishing to provide sunshine/oversight.

Some individuals are so dangerous and destructive that all members of society (including prison guards, staff, and other prisoners) deserve permanent protection from them. I have no issue with extinguishing the existence of those who are so fundamentally broken that we can't contain their violence. However, we need to bend over backwards to ensure the process to do that is applied fairly, reasonably, and is designed to make it as close to impossible to execute an innocent person as we can reasonably make it.

Capital punishment certainly can be "revenge killing", but it is not necessarily so. Personally, I think that if it's fairly applied and handled reasonably, it can be as simple as a society determining that an individual is simply too dangerous and destructive to be allowed to continue existing. I have no problem with that. Prison guards, staff, and indeed other prisoners are people too and they have a right to be protected from particularly destructive and dangerous individuals. At some point, it's fair to admit that you cannot adequately control the violence unleashed at every opportunity by someone who is fundamentally broken in a way we cannot fix.

The US Constitution doesn't give a damn about the rest of the world. Frankly, the rest of the world has such a sordid history (and present) that we should be thankful for that.

Capital punishment is long-established in the US. Taking the "cruel and unusual" approach won't get anywhere. Now if someone comes up with a particular method that's different enough (e.g. giant catapult, throwing people out of an airplane, letting alligators eat them, etc), you can attack the methods.

Oh please; they just realized how the drugs were being used? Decades of repeated, public use and some executive finally picked up a newspaper? Give me a break. What actually happened is that they periodically reevaluated the amount of money they made off sales versus the PR hit they took for making those sales and eventually the numbers tipped in a new direction.
