Real WMDs (Or, Ignorance is Bliss)

In an online commentary, Building a Nation of Know-Nothings, Timothy Egan uses John McCain's primary victory against "the flat-earth wing of his party" as the launching point to discuss the rather depressing trend in the Republican party to pander to imbeciles. (Okay, he was more delicate, referring to people with "head[s] stuffed with fabrications that could be disproved by a pre-schooler.") He writes,
It’s not just that 46 percent of Republicans believe the lie that Obama is a Muslim, or that 27 percent in the party doubt that the president of the United States is a citizen. But fully half of them believe falsely that the big bailout of banks and insurance companies under TARP was enacted by Obama, and not by President Bush. 


Take a look at Tuesday night’s box score in the baseball game between New York and Toronto. The Yankees won, 11-5. Now look at the weather summary, showing a high of 71 for New York. The score and temperature are not subject to debate.


Yet a president’s birthday or whether he was even in the White House on the day TARP was passed are apparently open questions. A growing segment of the party poised to take control of Congress has bought into denial of the basic truths of Barack Obama’s life. What’s more, this astonishing level of willful ignorance has come about largely by design, and has been aided by a press afraid to call out the primary architects of the lies.
The source of this "knowledge" is "the media" - in fact, a "lamestream media" all its own.
In the much-discussed Pew poll reporting the spike in ignorance, those who believe Obama to be Muslim say they got their information from the media. But no reputable news agency — that is, fact-based, one that corrects its errors quickly — has spread such inaccuracies.


So where is this “media?” Two sources, and they are — no surprise here — the usual suspects. The first, of course, is Rush Limbaugh, who claims the largest radio audience in the land among the microphone demagogues, and his word is Biblical among Republicans. A few quick examples of the Limbaugh method:


“Tomorrow is Obama’s birthday — not that we’ve seen any proof of that,” he said on Aug. 3. “They tell us Aug. 4 is the birthday; we haven’t seen any proof of that.”


Of course, there is proof as clear as that baseball box score. Look here, www.factcheck.org, for starters, one of many places posting Obama’s Hawaiian birth certificate. [More specifically, http://www.factcheck.org/elections-2008/born_in_the_usa.html -jwj]
...
Finally, there is Fox News, whose parent company has given $1 million to Republican causes this year but still masquerades as a legitimate source of news. Their chat and opinion programs spread innuendo daily. The founder of Politifact, another nonpartisan referee to the daily rumble, said two of the site’s five most popular items on its Truth-o-meter are corrections of Glenn Beck.
...
It would be nice to dismiss the stupid things that Americans believe as harmless, the price of having such a large, messy democracy. Plenty of hate-filled partisans swore that Abraham Lincoln was a Catholic and Franklin Roosevelt was a Jew. So what if one-in-five believe the sun revolves around the earth, or aren’t sure from which country the United States gained its independence?


But false belief in weapons of mass-destruction led the United States to a trillion-dollar war. And trust in rising home value as a truism as reliable as a sunrise was a major contributor to the catastrophic collapse of the economy. At its worst extreme, a culture of misinformation can produce something like Iran, which is run by a Holocaust denier.


It’s one thing to forget the past, with predictable consequences, as the favorite aphorism goes. But what about those who refuse to comprehend the present?

IdeaFestival 2010

The IdeaFestival will be held 29 September - 2 October at the Kentucky Center for the Performing Arts in Louisville, KY.  Here's a quick link to this year's program.
Founded in 2000, the IdeaFestival (IF) is a world-class event that attracts leading global innovators and thinkers to discuss and celebrate imagination, new perspectives and transformational ideas.
The IdeaFestival provides a unique stage to explore the cross-cutting nature of innovation involving a range of diverse disciplines, while supplying the creative tools needed to “see”, synthesize and apply this knowledge in new, dynamic ways.

Highly efficient solar cells from quantum dots

The 22 August 2010 edition of Texas Science reports on research by chemist Xiaoyang Zhu at The University of Texas at Austin suggesting that conventional solar cell efficiency could be more than doubled, from the current limit of 30% to more than 60% using semiconductor nanocrystals, or quantum dots to capture the energy from "hot electrons."
The maximum efficiency of the silicon solar cell in use today is about 31 percent. That’s because much of the energy from sunlight hitting a solar cell is too high to be turned into usable electricity. That energy, in the form of so-called “hot electrons,” is lost as heat.
If the higher energy sunlight, or more specifically the hot electrons, could be captured, solar-to-electric power conversion efficiency could be increased theoretically to as high as 66 percent.

 “If we take the hot electrons out, we can do work with them,” says Zhu. “The demonstration of this hot electron transfer establishes that a highly efficient hot carrier solar cell is not just a theoretical concept, but an experimental possibility.”
