1. Carmarketers like good gas mileage figures; they're good for sales.

2. The specifications for the test are gamed to provide a bigger benefit for underpowered cars which tend to get better mileage anyway. The test include acceleration at a rate *that depends on the car's power* (percent of full-throttle). which has the big-engine (more powerful) cars zipping around the virtual course at higher speeds.

Remember, lobbyists write or co-write most of our laws and regulations.

I don't usually respond to ACs but cause you're dead wrong and call me a liar, here's both barrels..

From the first link

We found that extracellular fields induced ephaptically mediated changes in the somatic membrane potential that were less than 0.5 mV under subthreshold conditions. Despite their small size, these fields could strongly entrain action potentials, particularly for slow (~8 Hz) fluctuations of the extracellular field. Finally, we simultaneously measured from up to four patched neurons located proximally to each other. Our findings indicate that endogenous brain activity can causally affect neural function through field effects under physiological conditions.

As to the 8 Hz magnetic resonance, see, which is the most nearly objective overview of this subject I can find right now. Wikipedia also has an article

DNA is magnetoresponsive. Magnetism itself is self-assembling, and since DNA has been shown to be magnetoresponsive and, it would be interesting to see if this origami folding can take place outside of the earth's magnetosphere, which has a magnetic harmonic at the same frequency as the resonance demonstrated by DNA.

Does anyone know anything about other self-assembling substances?

In many states in the US, all that's required for a "contract" to exist is agreement on actions AND compensation. That compensation does not have to be money; it may be anything of value, including one's attention (as to ads.) Other states do not limit contracts to need compensation at all. I dunno about other nations....

I agree. What's more, Apple might have to press hard on the common use of the term "iPad" to refer to tablets in general. Bayer long ago lost the exclusive rights to the word aspirin by not enforcing its exclusivity. 3M took great pains in the 70s to make clear "Scotch" did not become another word for "transparent", as in tape; Coke, McDonal's, et al. have enforced such. Now it may be Apple's turn.
Oh, and as for MS :"What goes around, comes around." Whatever that means....

+ - Feynman Lectures Released Online, Free 2

Submitted by Anna Merikin
Anna Merikin (529843) writes "In 1964, Richard Feynman delivered a series of seven hour-long lectures at Cornell University which were recorded by the BBC, and in 2009 (with a little help from Bill Gates), were released to the public. The three-volume set may be the most popular collection of physics books ever written, and now the complete online edition has been made available in HTML 5 through a collaboration between Caltech (where Feyman first delivered these talks, in the early 1960s) and The Feynman Lectures Website. The online edition is "high quality up-to-date copy of Feynman's legendary lectures," and, thanks to the implementation of scalable vector graphics, "has been designed for ease of reading on devices of any size or shape; text, figures and equations can all be zoomed without degradation."

Volume I deals mainly with mechanics, radiation and heat; Volume II with electromagnetism and matter; and Volume III with quantum mechanics."

I didn't need anyone to tell me I was smart. I figured it out myself. As you say, I was "smart" at the subjects I loved and not so much at others. Now, as an "elder", I tell those coming up If you want to be rich and-or famous, develop your talents. But if you want to be happy, work on your weaknesses: Become round.

BTW, If someone had told me life could be so good at 71 years, I'd have had more courage in my youth.

I have seen about 440 BTU/hr/ft^2. in solar reflector design manuals. This is close to your figure for solar radiation. I have no idea about ocean vent heating, as the *data is not yet available.* This is the point of the article -- that the data is only now being gathered. One data point: The part of the vulcanism measured in the North Atlantic produces one cubic kilometer of new rock every year. What is the heat equivalent of that? I don't know. What part of the earth's total undersea heating does this constitute? I have no idea. How does this affect surface currents, if at all? I dunno. How do surface currents impact weather/climate patterns? No one is sure. Not even you. But, we may soon know these things.

Cuadrilla drilling company in UK has admitted publicly the link between fracking and earthquakes. The said this in 2011

"It is highly probable that the hydraulic fracturing of Cuadrilla's Preese Hall-1 well did trigger a number of minor seismic events
