"Silicon photonic crystals key to optical cloaking:
...[R]esearchers have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals.
... "This is much more than a theoretical exercise," said Harley Johnson, a Cannon Faculty Scholar and professor of mechanical science and engineering at Illinois. "An optical cloaking device is almost within reach."

Judge officially rules that Duke football sucks:
Judge agrees: Duke football as bad as it gets(Via Volokh.)
A Franklin, Ky., Circuit Court judge sided with a devilishly clever argument and ruled in favor of Duke University yesterday in a breach of contract lawsuit brought forth by the University of Louisville.
Judge Phillip J. Shepherd agreed with Duke's lawyers — the football team is so bad that any replacement would do.
U of L sued Duke for $450,000 — or a series with another Atlantic Coast Conference opponent — after the Blue Devils backed out of a four-game football contract with three dates remaining.
The contract called for a penalty of $150,000 per game if a date with a "team of similar stature" could not be arranged.
Duke's lawyers argued the Blue Devils, which have a record of 6-45 over the past five seasons, were so bad that any team would be a suitable replacement.
Judge Shepherd agreed in his summary:
"At oral argument, Duke (with a candor perhaps more attributable to good legal strategy than to institutional modesty) persuasively asserted that this is a threshold that could not be any lower. Duke’s argument on this point cannot be reasonably disputed by Louisville."

"Is the Universe Actually Made of Math?"
Or is this just a new twist on the philosophical doctrine of "idealism"?
(Perhaps I'm misunderstanding Tegmark's thesis, but I must confess that I have no idea how mathematical ideas can be the underlying substrate of reality, with physical beings and thinking minds arising from them. That seems like a total inversion of the dependence relationship, since one would think that ideas can only exist if they are generated by a conscious mind or minds.)

Off-topic weekend political post on Ted Kennedy and "universal" health care. Someone sent me the following excellent essay by Dr. Richard Parker. I agree with every word:
Ted Kennedy vs. Universal Healthcare: A Double Irony
by Richard Parker M.D. (June 9, 2008)
Senator Ted Kennedy recently underwent an operation to remove a brain tumor at Duke University. Besides Hillary Clinton, no other politician in America has devoted as much of his political career to the enslavement of physicians. The name Ted Kennedy (and Clinton) is nearly synonymous with the anti-concept "Universal Healthcare."
It was reported that Senator Kennedy chose his surgeon for this difficult operation after very careful research and consultation with his physicians in Boston. Using his free and independent judgment, Kennedy chose Dr. Allan Friedman, a surgeon renowned for his experience and expertise in the field of neuro-oncological surgery.
No government regulations restricted the Senator in this extremely important personal choice. Facing a life threatening illness, no bureaucrat forced the Senator to chose his surgeon nor hospital from a government "approved" list--a list not generated by Kennedy's independent and free judgment, but by "public servants" whose expertise is not Kennedy's life, but the arbitrary and byzantine politics of "pull", of favors owed and collected, of political pressure groups and the bitter reality of healthcare rationing. No, Kennedy was not forced to sacrifice his life, liberty nor property in the name of the so-called "greater public good."
The surgeon he chose, Dr. Allan Friedman, has freely devoted his life to treating patients with neurological tumors. Dr. Friedman wasn't coerced into medicine; his patient load is not presently rationed nor stipulated by bureaucrats. Dr. Friedman was still free to accept Senator Kennedy as his patient and was free to choose the best surgical approach for treating the Senator's tumor. No bureaucrat stipulated how many patients per day, week, month or year Dr. Friedman may accept and treat during the long decades he spent perfecting his life-saving skill. Dr. Friedman is still relatively free to use his expert judgment in the face of the awesome responsibility he assumes with each patient he treats.
Ironically, however, if Senator Kennedy succeeds in his ambition of forcing a government financed (and therefore government controlled) healthcare system onto the American people, all these life altering and personal freedoms will vanish with the strokes of a few pens in Washington. This is the reality of any government enforced healthcare system—both patients and physicians will face a vast increase in taxation and the loss of additional property (fines) and liberty (imprisonment) if they violate the morass of arbitrary and contradictory regulations that will descend on a healthcare industry that is already all but crippled with the slow but steady creep of government controls over the past 50 years.
In her novel Atlas Shrugged, Ayn Rand predicted one of the most pernicious aspects of so-called "Universal Healthcare"—the refusal of talented minds to be forced at the point of a gun. Dr. Hendricks, a neurosurgeon in Atlas Shrugged, describes the indignation that lead him to leave medicine:"Do you know what it takes to perform a brain operation? Do you know the kind of skill it demands, and the years of passionate, merciless, excruciating devotion that go to acquire that skill?... I observed that in all the discussions that preceded the enslavement of medicine, men discussed everything--except the desires of the doctors... I have often wondered at the smugness with which people assert their right to enslave me, to control my work, to force my will, to violate my conscience, to stifle my mind--yet what is it that they expect to depend on, when they lie on an operating room table under my hands? Their moral code has taught them to believe that it is safe to rely on the virtue of their victims. Well, that is the virtue I have withdrawn."Ted Kennedy will undoubtedly continue his push for the enslavement of physicians with what remains of his political career. What he will evade, of course, is that his surgeon chose to go to medical school and spend decades training for and practicing neurosurgery in what is still the freest healthcare system in the world. What Kennedy will refuse to acknowledge is that under his vision of “Universal Healthcare” he would never have had the absolute freedom to choose his surgeon, nor would his surgeon have had the absolute freedom to treat him.
The fact that "Universal Healthcare" will destroy what freedoms in American medicine still remain (and thus all the Dr. Friedman's under whose virtue the fate of Kennedy's brain now lies), will be not only evaded but explicitly denied—never mind that Kennedy chose not to go to one of the many "industrialized countries that provide 'Universal Healthcare'." Apparently, Kennedy ignored Michael Moore's claims of the excellent healthcare provided in other “industrialized” communist and socialist nations that provide "Universal Coverage", albeit this is precisely what Kennedy seeks to bring to America at the point of a gun.
While the successful outcome of Senator Kennedy's operation depended on freedom, Kennedy has devoted his political career to legislating freedom out of existence. This is an irony that America's news media will evade, much less report.
Richard Parker is a practicing physician in the Dallas-Fort Worth area. He holds and MD from Brown and MD from Yale University. He has published in the scientific literature and has written Op-eds for the Ayn Rand Institute and Capitalism Magazine.

Bruce Schneier discusses the new TSA requirement to show one's photo ID:
The TSA has a new photo ID requirement:Daniel Solove adds:Beginning Saturday, June 21, 2008 passengers that willfully refuse to provide identification at security checkpoint will be denied access to the secure area of airports. This change will apply exclusively to individuals that simply refuse to provide any identification or assist transportation security officers in ascertaining their identity.That's right; people who refuse to show ID on principle will not be allowed to fly, but people who claim to have lost their ID will. I feel well-protected against terrorists who can't lie.
This new procedure will not affect passengers that may have misplaced, lost or otherwise do not have ID but are cooperative with officers. Cooperative passengers without ID may be subjected to additional screening protocols, including enhanced physical screening, enhanced carry-on and/or checked baggage screening, interviews with behavior detection or law enforcement officers and other measures.
...[T]his rule will allow TSA officials who don't like you to have even greater power. If you lose your ID, you better hope that the TSA officials believe you, take pity on you, and otherwise think you're being cooperative. It's entirely up to them!

"Antarctica base gets 16,500 condoms before darkness":
One of the last shipments to a U.S. research base in Antarctica before the onset of winter darkness was a year's supply of condoms...It sounds like the issue is that people may become a little bit too comfortable during the long dark winter months...
Bill Henriksen, the manager of the McMurdo base station, said nearly 16,500 condoms were delivered last month and would be made available, free of charge, to staff throughout the year to avoid the potential embarrassment of having to buy them.
The base only has a skeleton staff through the long winter.
"Since everybody knows everyone, it becomes a little bit uncomfortable," Henriksen told the Southland Times newspaper.

"Fake bus stop keeps Alzheimer's patients from wandering off":
The idea was first tried at Benrath Senior Centre in Düsseldorf, which pitched an exact replica of a standard stop outside, with one small difference: buses do not use it.(Via Look At This...)
The centre had been forced to rely on police to retrieve patients who wanted to return to their often non-existent homes and families.
..."They know the green and yellow bus sign and remember that waiting there means they will go home."
The result is that errant patients now wait for their trip home at the bus stop, before quickly forgetting why they were there in the first place.
"We will approach them and say that the bus is coming later and invite them in for a coffee," said Richard Neureither, Benrath's director. "Five minutes later they have completely forgotten they wanted to leave."

Security stupidity Because of "security concerns", tourists and amateur photographers visiting the Amtrak Union Station in Washington DC are told they can't take pictures. A local TV news team went to investigate this story.
The best part of their video was when a security guard came up to the camera crew and told them there was no photography allowed, right as the chief Amtrak spokesman was telling the reporter that there was no ban whatsoever on photography.
