	John Preskill - Wikipedia, the free encyclopedia
		John Phillip Preskill (born 19 January 1953) is an American theoretical physicist and a professor at the California Institute of Technology (Caltech).
		Preskill is an outstanding teacher and many of his students are well-known physicists.
		Preskill has achieved some notoriety in the popular press as party to a number of bets involving fellow theoretical physicists Stephen Hawking and Kip Thorne.

	Thorne-Hawking-Preskill bet - Wikipedia, the free encyclopedia
		Thorne and Hawking argued that since general relativity made it impossible for fl holes to radiate, and lose information, the mass-energy and information carried by Hawking radiation must be "new", and must not originate from inside the fl hole event horizon.
		Preskill argued the opposite, that since quantum mechanics suggests that the information emitted by a fl hole relates to information that infell at an earlier time, the view of fl holes given by general relativity must be modified in some way
		In 2004, Hawking announced that he was conceding the bet, and that he now believed that fl hole horizons should fluctuate and leak information.

		John Preskill's main current interest is in quantum computation.
		Preskill, with students and postdocs, is working on devloping new algorithms that could be executed by a quantum computer, and on new schemes for protecting quantum computers from decoherence and other sources of error.
		Preskill's other interests include the physics of the very early universe, the quantum properties of fl holes, and nonperturbative aspects of quantum field theory.

		Preskill has now received a Baseball Encyclopedia from Hawking, in front of hundreds of witnesses, but both Preskill as well as Thorne need more time to study Hawking's 2004 answer.
		And whereas John Preskill firmly believes that a mechanism for the information to be released by the evaporating fl hole must and will be found in the correct theory of quantum gravity,
		John is all-American, so naturally he wants an encyclopaedia of baseball.

		At this point the encyclopedia was brought on stage and given to John Preskill, who waved it over his head in a parody of athletic triumph.
		Preskill chimed in, saying "I'll be honest - I didn't understand the talk", and saying that he too would need to see more details.

	Hawking concedes black hole bet (Site not responding. Last check: 2007-10-23)
		The physicist was forced to concede a bet he made with American theoretical physicist John Preskill in 1997 as he unveiled his new theory on Wednesday.
		Preskill had doubted Hawking's theory that fl holes destroy everything that falls into them.
		But Hawking was ready to concede the bet that he and Thorne had made with Preskill.

	Caltech Press Release, 2/6/1997, Stephen Hawking, Kip Thorne, John Preskill
		He conceded today a 1991 bet he made with Caltech physics professors Kip Thorne and John Preskill that a phenomenon known as the naked singularity is possible.
		Thorne and Preskill think that naked singularities are allowed by nature.
		According to Thorne and Preskill, there should be situations in which singularities could exist outside of fl holes and therefore be observed.

		In a humorous aside, Hawking settled a 7-year-old bet made with Caltech astrophysicist John Preskill, who insisted in 1997 that matter consumed by fl holes couldn't be destroyed.
		He presented Preskill a favored reference work "Total Baseball, The Ultimate Baseball Encyclopedia" after having it specially flown over from the United States.
		Later, Preskill said he was very pleased to have won the bet, but added: "I'll be honest, I didn't understand the talk." Like other scientists there, he said he looked forward to reading the detailed paper that Hawking is expected to publish next month.

		Preskill, John D. MacArthur Professor of Theoretical Physics at Caltech, and Director of IST's Center for the Physics of Information, made a bet in 1997 with Hawking and Thorne that information is indeed preserved upon entering a fl hole, and is not destroyed, as Hawking and Thorne maintained.
		While Hawking now agrees with Preskill, Thorne has yet to concede the bet.

	Hawking Concedes Black Hole Bet - Science -
		He paid up on a friendly bet with colleague John Preskill of Cal Tech this week after announcing his reversal.
		Cosmologist Stephen Hawking made a special presentation to his associate, California Institute of Technology physicist John Preskill, at a scientific conference this week: a copy of "Total Baseball, The Ultimate Baseball Encyclopedia," which Hawking had specially flown over from America.
		Now, Hawking says, he thinks Preskill was right: Black holes eventually disintegrate, and as they do, they release sub-atomic particles that may carry clues about the inner workings of the fl hole.

	Universe Today - Black Holes Maintain Their Information
		Tue, 02 Mar 2004 - In 1997, cosmologists Stephen Hawking, Kip Thorne, and John Preskill made a bet about what happens to a fl hole when material is sucked into it.
		Stephen Hawking and Kip Thorne may owe John Preskill a set of encyclopedias.
		In 1997, the three cosmologists made a famous bet as to whether information that enters a fl hole ceases to exist -- that is, whether the interior of a fl hole is changed at all by the characteristics of particles that enter it.

	I’ll Bet You the Universe
		In reversing a conviction he’s held for thirty years—that these massive gravitational vacuums destroy all the information about the matter that falls into them—Hawking also publicly conceded a longstanding, friendly wager he made with colleague John Preskill in 1997.
		Although Hawking only recently announced this conclusion to the public, Preskill has long had an inkling he would win the bet.
		Still, his admission that information is preserved within the fl hole begs the question of what happens to it, and Preskill said this conundrum continues to perplex the physics community.

		Of the many reasons why this suit would be extremely difficult to win, a primary one is that the plantifs would reportedly need to “show that their citizens are suffering significantly more than the nation as a whole.”
		John Preskill has NOT declined his encyclopedia (Total Baseball: The Ultimate Baseball Encyclopedia), as the terms of the bet were that it would be given when the other party concedes.
		In his own words “I don’t have to agree” Encyclopedias were settled upon as the basis of the bet was whether information was conserved even under the conditions of a fl hole, and encyclopedias were determined to be a source from which information could be extracted reliably.

		If he succeeds, then, ironically, he will lose a bet that he and theoretical physicist Kip Thorne of the California Institute of Technology (Caltech) in Pasadena made with John Preskill, also of Caltech.
		They argued that "information swallowed by a fl hole is forever hidden, and can never be revealed".
		The duo are expected to present Preskill with an encyclopaedia of his choice "from which information can be recovered at will".

		First, when I was giving a little talk on Clifford algebras at Nottingham University after the ICMP, I needed to look up a few things, and I bumped into this book: 14) P. Budinich and A. Trautman, The Spinorial Chessboard, Springer-Verlag, Berlin, 1988.
		It has a nice discussion of the "Clifford algebra clock": R R+R C R H C H+H H As I explained in "week105", this clock easily lets you remember the real Clifford algebras in every dimension and signature of spacetime.

		I went and looked at the various options out there, it had to be free, and be either perl or PHP base as that is what her hosting provider supports.
		I ended up testing both, but selecting the phpODP version because it is PHP based (easier to integrate into a PHP based site) and more importantly, it uses a caching system to speed up the DMOZ searches.
