"The suffix "-ene" indicates that each C atom is covalently bonded to three others (instead of the maximum of four), a situation that classically would correspond to the existence of bonds involving two pairs of electrons ("double bonds")."
If memory serves, (A-level chem, late 1970s) in compounds containing carbon rings, each C atom has bonds to three others, but the fourth bonding electron is "de-localised." This enables it to move fairly freely over the surface of the rings, so it can conduct electricity. Graphite is the usual example.
Disclaimers: I may have mis-remembered. The picture may have been simplified. Knowledge in the field may have progressed to the point where the above is no longer accurate.
p.s. I don't know if the delightfully-named ring molecule Arsole is conductive, but I don't care.
Re: Another category where prices are "interesting"
"BG is the most extreme over-charger"
Yup. I let BG quote for my new boiler, just for entertainment purposes. Not suprisingly, they wanted 5k where other quotes came in at around 2-3k. I feel sorry for the people who are taken in by them.
Oh and I hate those vile caricatures on their ads and web-site; those freaky people with huge heads and tiny bodies. Big turn-off. It givesme extra pleasure in waking my wood burner, getting the place all toasty FOR FREE.
Re: In other words...
"Yup, just like people knew a long time ago. Observations like this were made at least ten years ago, if not 20 years ago."
Yes! I recall having some "Anklebiter's Book of Science" maybe 30- 40 years ago, with a section called "Nature Beat Man to it" (or similar). It showed how the feathers on the trailing edge of owls' wings had gaps between them. The text explained that this broke up the airflow and reduced the noise. Similar methods were used on the arse-end of jet engines to make them quieter (paraphrasing a little).
Maybe there is something new here, possibly in the mention of the softer materials and porosity.

Boy, am I in trouble? Just last night, I made a ton of popcorn, which was a direct copy of Genuine Overpriced Cinema Popcorm (TM). My offspring were unknowingly nomming PIRATED POPCORN, stealing money straight out of the mouths of the cinema industry, er- literally.
I await the knock on my door and the prospect of a cold winter after having my gas cut off (because that was used for the copying).
re: Power usage
"A simple cat's whisker can pick up (analogue) FM signals hence why battery drain on a portable FM radio is pretty low....whereas a multiplexed digital signal needs to be "processed" in order to extract the radio signal of the station you want to hear - hence why the battery drain on a portable DAB set will be much higher."
No. I don't know if this comes out of the Daily Mail Radio Design Handbook, but it is cobblers.
A 'cat's whisker' makes a simple diode detector, which extracts the _envelope_ or amplitude of the signal. For an AM broadcast, this is a simple way of recovering the audio.
In FM, the signal's amplitude carries no information at all. A diode detector will give you nothing, nada, zip (*). In fact, an FM receiver will have some stages which intentionally limit the signal amplitude, keeping it perfectly flat.
The need for digital processing is real enough, though; you need to pull out the right bit stream, before turning it back into audio.
(*) Ok, if you manage to detune to one side of the signal, you may manage some crude slope-detection, using the edge of your filter's passband.

<Reply-all> may not be the problem
During the last international mail-storm here , I watched hundreds of "unsubscribe" emails being sent to the entire list. My first thought was that many colleagues were foolishly hitting Reply-all. In fact, they were actually (still foolishly) using Reply.
Most list-servers in my humble experience simply treat a Reply as a Reply-to-list; you need to use a different admin address if you want out. List members tend to forget or lose this vital piece of info. At work, entire departments may get signed up to new lists, with little warning.
Some list-servers at least may trap any unsub requests, but it doesn't seem to be default.
Still, that's my observation as a user, not an IT admin of any sort.
"In Japan nearly all the men smoke but they don't get lung cancer."
Cancer rates certainly appear lower than, say, those in the US. Some interesting reading:
Possible explanations for this difference in risk include a more toxic cigarette formulation of American manufactured cigarettes as evidenced by higher concentrations of tobacco-specific nitrosamines in both tobacco and mainstream smoke, the much wider use of activated charcoal in the filters of Japanese than in American cigarettes, as well as documented differences in genetic susceptibility and lifestyle factors other than smoking.

Re: Power Cuts
"For a brief moment, I felt like I held the world's most powerful remote control in my hand."
A few weeks back, I was having an unpleasant motorway drive, though driving rain. I was relieved to reach my junction but the traffic lights at the end of the slip road turned red to spite me. I called to the great god Bollocks, who obliged with a lightning bolt which took out all the traffic lights. I smiled in thanks.

Nah - just another gardener and mollusc hater. You are in good company. Snails are usually treated to the Dropkick of Destiny, while slugs get the Heel of Justice.
Re: Wouldn't have happened...
"... trashes the tire too..."
I believe that's a myth. While I don't have personal experience here, I have read accounts from several peeps who have had the gunk scraped out and the tyre successfully repaired later. Some repair places may have propagated the idea that it's not possible, maybe because they don't know better, or can't be bothered.
"as much credibility as a wide-eyed bible belt church gazette warning about the danger of Dungeons And Dragons turning your kid into a satanist."
Aksherly, a chap I worked with, decades ago, told me that he'd been heavily into D&D while at college. Being also of an Xtian persuasion, he told me that his priest/vicar/whatever had warned him that D&D was associated with the Occult and therefore dangerous. So, he promptly gave it up. He seemed proud of his decision, yet, I thought, somewhat wistful. He was also into shooting and survival stuff, which is fairly odd in the UK. Still, he was a pleasant enough chap to talk to. Maybe he's reading this.

"Why is there so much anger in this thread?"
Why? Perhaps it's because non-Americans see something very bad happening in a rich, powerful and influential country. Inculcating children with fairy tales and passing them off as The Truth, so that many will grow up to be believers and possibly educators of the next generation. It's a nasty self-perpetuating cycle.
Perhaps people are angry because they care about this abuse of intelligence and the long-term effects on the population.

So why are they 100% useless in stopping their spammers? Every Korean spam that I have reported to the appropriate Abuse@ addresses has been rejected.

Re: Banning a man from his shed?
"But would it really be the same shed if he replaced a part of it?"
I was also wondering. This problem has occupied thinkers for millennia and has the official name "Ship of Theseus." More info at http://en.wikipedia.org/wiki/Ship_of_theseus
Of course, this does not answer whether the _intention_ of the ruling was to permanently deprive the man of his shed, any shed; a cruel and unusual punishment, probably covered under the Geneva Convention.

"I like the occasional reminder that we no longer need to use 'bang' email addresses."
I quite miss them. They were the common syntax when I started using email for work. Was there a time when both "!" and "@" versions were acceptable formats? Thunderbird won't accept "!" now though.
"May I just point out that is would actually be pronounced JIF in the English language since the G is followed by a I as in Giraffe."

Re: illegal download sites
"The big issue is continuous authority (or even non continuous authority) credit and debit cards. If a company takes money from your card it can keep doing so and you can't cancel the authority via the bank at all."
Yup - that's the problem with doing business with dishonest weasels like Budget Insurance. They'll swear blind that they wouldn't automatically renew a policy, but then go ahead and do it anyway. I even got them to send me a second renewal reminder, with the "Just do nothing and we'll help ourselves to your money" removed, and they STILL tried to take it. Fortunately, my card had just been re-issued with a new number, so their attempt failed. Then, they had the gall to request an "admin fee" for the failed payment.
As mentioned, the credit card companies seem amazingly disinterested in preventing these unauthorised and specifically-forbidden transactions. "Just claim it back" was the helpful advice.
