Elevator at Biltmore House. Image: Biltmore CompanyEight pages of a sort of trivia, just the thing after a hard day at the office.

“Two things make tall buildings possible: the steel frame and the safety elevator. The elevator, underrated and overlooked, is to the city what paper is to reading and gunpowder is to war. Without the elevator, there would be no verticality, no density, and, without these, none of the urban advantages of energy efficiency, economic productivity, and cultural ferment. The population of the earth would ooze out over its surface, like an oil slick, and we would spend even more time stuck in traffic or on trains, traversing a vast carapace of concrete. And the elevator is energy-efficient—the counterweight does a great deal of the work, and the new systems these days regenerate electricity. The elevator is a hybrid, by design.”

“[...] In most elevators, at least in any built or installed since the early nineties, the door-close button doesn’t work. It is there mainly to make you think it works. (It does work if, say, a fireman needs to take control. But you need a key, and a fire, to do that.) Once you know this, it can be illuminating to watch people compulsively press the door-close button. That the door eventually closes reinforces their belief in the button’s power. It’s a little like prayer [...]”

you’re all doo-o-o-o-o-o-o-o-o-o-o-o-o-o-m-e-d-d-d-d-d-d-d - a black hole is coming to get you

“The lawsuit, filed March 21 in Federal District Court, in Honolulu, seeks a temporary restraining order prohibiting CERN from proceeding with the accelerator until it has produced a safety report and an environmental assessment. It names the federal Department of Energy, the Fermi National Accelerator Laboratory, the National Science Foundation and CERN as defendants.

“But Walter L. Wagner and Luis Sancho contend that scientists at the European Center for Nuclear Research, or CERN, have played down the chances that the collider could produce, among other horrors, a tiny black hole, which, they say, could eat the Earth. Or it could spit out something called a "strangelet" that would convert our planet to a shrunken dense dead lump of something called "strange matter." Their suit also says CERN has failed to provide an environmental impact statement as required under the National Environmental Policy Act.

“Although it sounds bizarre, the case touches on a serious issue that has bothered scholars and scientists in recent years - namely how to estimate the risk of new groundbreaking experiments and who gets to decide whether or not to go ahead.”

the foibles of human nature - mills/mccartney, obama

A judgment and a speech with plenty to read should you be bored.

“not just inconsistent and inaccurate but also less than candid.” [58-page .pdf]

This looks like a reasonable summing up of 58 pages of dense text, and shows Paul McCartney as surprisingly generous, modest and tolerant.

“15. The husband’s evidence was, in my judgment, balanced. He expressed himself moderately though at times with justifiable irritation, if not anger. He was consistent, accurate and honest.

“16. But I regret to have to say I cannot say the same about the wife’s evidence. Having watched and listened to her give evidence, having studied the documents, and having given in her favour every allowance for the enormous strain she must have been under (and in conducting her own case) I am driven to the conclusion that much of her evidence, both written and oral, was not just inconsistent and inaccurate but also less than candid. Overall she was a less than impressive witness.”

And some hilarity:
“[...] She places great weight on the contributions she says she has made to counselling the husband’s.......and to the husband’s professional career [...]”

If only more of these transcripts were publically available in the secretive UK culture.

Full transcript of Barack Obama’s speech today

To me, this speech looks like another of those political speeches where the more you examine it and discount the rhetoric, the less content remains.

Marker at abelard.org

From another Obama sceptic:

“Deconstructing Obama's lawyerly evasions on Wright”

“ "...not statements I personally heard him preach while I sat in the pews of Trinity..."

“This leaves so many doors open for evasion. We noticed on the videotaped sermons that when Rev. Wright fires up the crowd, they jump to their feet. A Harvard-trained lawyer like Obama inserting the phrase "sat in the pews" knows exactly what he is doing. If he was on his feet applauding and shouting approval like so many other Trinity congregants, then this statement becomes true, if utterly misleading.

“ "...or heard him utter in private conversation."

“So if his wife Michelle, or any other person (a staffer or fellow congregant, for instance) was with Obama when he heard such statements, then he didn't hear them in private conversation. Harvard-trained lawyers know that every adjective adds a condition which must be met in order to prove that a denial is false, not just misleading.

“ "When these statements first came to my attention..."

“ "Came to my attention" is a wonderful phrase. That's the sort of artistry that earns Harvard-trained lawyers their hundreds of dollars an hour rates. "Attention" requires an active psychological engagement. If Wright routinely makes such statements, Obama would pay no attention to them because they are almost boilerplate. Israeli state-sponsored terrorism? Why bother paying attention? Wright has been attacking Israel for years. God damn America? Wright has been railing against this country for years. Who pays attention to routine stuff?”

And more of the same.

new faster security biotech detection - three minutes in public spaces [on p.4 of 8-page .pdf]

PANTHER air biodetector. Image: MIT Lincoln Laboratory“The device could be used in buildings, subways and other public areas, and can currently detect 24 pathogens, including anthrax, plague, smallpox, tularemia and E. coli.”

“[...] Current sensors take at least 20 minutes to detect harmful bacteria or viruses in the air, but the PANTHER sensors can do detection and identification in less than 3 minutes.”

Innovative Biosensors, Inc. (IBI), the licensee the PANTHER technology, began selling a product, BioFlash, that uses the PANTHER technology. Note that, previously, BioFlash used the precursor to PANTHER - CANARY, which can detect 21 potential pathogens.

“The new device, PANTHER, takes the CANARY technology and combines it with an air sampler that brings pathogens into contact with the detector cells.”

No price given.

making photovoltaics cells more efficient would also protect them from the sun

“Scientists have found a way to increase the lifespan of solar cells by coating them with a material that converts ultraviolet photons into ones of visible light. Essentially, this takes UV rays and stretches them into longer wavelengths, resulting in greater efficiency for the panel and reducing damage to the cells.”

“a patent: photo-conversion materials (pcms) in polymer solar cells-enhancement efficiency and prevention of degradation”

“It is important for solar cells to exploit as efficiently as possible the full solar spectrum in order to improve power conversion cell efficiencies to a point that practical, widespread, and low-cost utilization is feasible. This is even more important in organic (small molecule and polymer) solar cells, in which the external quantum efficiency (EQE) varies more strongly with the wavelength of the incident light than their inorganic counterparts. In many organic photovoltaic systems, the maximum EQE values lie within the visible range, whereas EQE values in the UV range are smaller. Therefore, conventional organic photovoltaic cells do not convert UV light to electrical power efficiently. Furthermore, the natural exposure of photovoltaic cells to UV light can lead to damage and degradation of the device over time.”

Using the cyper goggles to see and label a plant. Credit: http://www.asahi.com/ memorise as you look

“Designed to function as a high-tech memory aid, these “Cyber Goggles” promise to make the act of losing your keys a thing of the past, according to head researcher professor Tatsuya Harada.

“Cyber Goggles are equipped with a compact camera that feeds video to a computer worn on the user’s back. The computer records the footage and relies on ultrahigh-speed image recognition processing software to analyze, name and file the objects that appear in the video. Later, when the user types in a keyword to search for a particular item, the corresponding video plays on a tiny LCD screen attached to the right-side lens, helping the user remember the location of the item in question.”

how long should copyright last? - the auroran sunset

A statistical study says 14 years, which is amazingly similar to what was suggested in the orginal Copyright Act of 1790.

“He develops a set of equations focused specifically on the length of copyright and uses as much empirical data as possible to crunch the numbers. The result? An optimal copyright term of 14 years, which is designed to encourage the best balance of incentive to create new work and social welfare that comes from having work enter the public domain (where it often inspires new creative acts).”
