http://www.perimeterinstitute.ca/I cant find a lecture on the firewall theory right now as the site is down for maintenance but these fine folk can probably tell you all about it,
Though you might want to follow Leonard Susskind's primers on YouTube first

Perimeter Institute and Quantum to Cosmos
The Perimeter Institute for Theoretical Physics is doing great work with its public outreach program that includes public lectures that are always have full attendance and which are available online. This year they are holding the Quantum to Cosmos Festival from Oct. 15 to 25. From the "About" page: "For 10 exciting days this October, Perimeter Institute's Quantum to Cosmos: Ideas for the Future (Q2C) will take a global audience from the strange world of subatomic particles to the outer frontiers of the universe. All events will occur on-site in Waterloo, Ontario and online at q2cfestival.com."

Re: Perimeter Institute
I hope Research in Motion's Perimeter Institute takes off.
Perimeter Institute is unrelated and not part of Research in Motion. A substantial chunk of original funding and enthusiasm was provided by Mike Lazaridis.

The Perimeter Institute recently gave a lecture on this, by Brian Schmidt, Australian National University - "The Universe From Beginning to End". I understand they will EVENTUALLY make these lectures available on their website, after they've made a bit of money by showing them on Discovery etc: https://www.perimeterinstitute.ca/en/Outreach/Public_Lectures/Public_Lectures/

douche bag rehab
It does make me wonder, however, of the bad stuff that gets falsely pinned to Dick, if the guy is really that bad at all.
With this logic, you could rehab almost anyone. There exists x who makes false claim y, therefore Cheney is chummy. The only qualification on x is ability to shoot mouth off. x could be the first person booted off American Idol and do no damage to your lemma as stated.
In fact, I read an article last night which said much the same about Ferdinand Marcos. After finishing Cryptonomicon, I was checking up Yamashita's gold. Everything else in the book with a historical basis I was familiar with already.
http://en.wikipedia.org/wiki/Yamashita's_gold
Apparently some people fervently believe that Marcos didn't extra billions in wealth from the Philippines, but instead helped himself to gold extracted by the Japanese with ruthless efficiency pretty much anywhere they went during the war and the years leading up to the war.
Today I watched this video, via Edge. This is Taleb speaking at the Perimeter Institute on the leading edge of the aftermath of the downside of belief in fragile statistics.
http://streamer.perimeterinstitute.ca/Flash/a28b2897-507f-40e2-8b71-e5d26992a01a/viewer.html
To cover inference from stupidity, as a higher grade of fragile statistic, we'd have to exhume Cantor to construct some whole new cardinalities.
Bad statistical instinct:
Stupid person x said y about z, therefore z isn't so bad after all.
Good statistical instinct:
Stupid person x said y about z, therefore what the hell am I doing loitering around here with spam shields inoperative?

When we ran Freedom of Information queries to see what was behind it, we were grudgingly sent a copy of a telex message on which every word was blacked out, including the date. The justification given for this censorship was the need to protect government sources, which are above the law.
This source has so many shades of dubious it makes my eyes bug out, but one nevertheless wonders what Cheney actually deserves. Not judging so much by this, but other things, Cheney didn't find himself in a swirling cloud of false accusations by accident. Some transparency here and there from the Bush administration would have greatly reduced this effect.

Perimeter Institute - Cool Stuff Going On -Eh
Don't know if the Canadians are working on making a name for themselves in Theoretical Physics, but PI certainly is doing it for them. Attracting Hawking fits what they've been up to.
They also have a strong public outreach with public lectures; and if you're not close enough to attend you can view the past lectures at:

what's old is new again
From one of the resources on superstring theory
Why do we see only point-like entities? The answer is simple: elementary strings, if they exist, are far too tiny to see. It is unlikely that even the most sophisticated microscope or particle accelerator that could be constructed would ever have enough resolution to directly "see" the strings of string theory.
Sounds like Epicurus all over again - small, indivisible, and invisible particles whose motion explain everything. Only he called them atoms.
I know superstring theory has better explanatory power than Epicurus' atomism, but I am intrigued by the invisibility of the strings, which the resourse above seems to make elementary, just like Epicurus.

Web page is wrong
The Einstein portrait caption reads "1870-1955". Einstein was born in 1879, the same year when Maxwell died.
Let's hope their theoretical physicists are more careful than their webdesigners.

Re:Computer Model Proves GeoCentrism
Sorry to reply to my own post, but I carelessly forgot to add that you can learn more from a Preimiter Institute lecture on the subject, available here:

Public Lectures
One of the coolest things about the Perimeter Institute is that they have a public lecture series. The lecturers are a mix of eminent scientists from inside and outside the Institute. The topics are mostly drawn from the edges of physics and cosmology. Some are more accessible to lay people than other.
The Institute has most of them available for offline viewing and reading. Maybe they could get Stephen Hawking one day. -
Simon Singh
I've enjoyed all of Simon Singh's books, but Fermat's Enigma really stands out.
"Math's Greatest Riddle" stood for 350 years taking swings from many a great thinker.
Singh makes the math easy to understand,
but what's REALLY interesting is the people who made progress towards the proof.
Like Sophie Germain who disguised herself as a man, "Monsieur Le Blanc" in order to become a mathematician.
He also did a similar treatment for Physics in "The Big Bang".
Thanks to you fine slashdotters, I watched his entertaining talk on the book at the Perimeter Institute. -

They just recently snagged Dr. Neil Turok from Cambridge to serve as the the executive Director - it looks like we will soon have all of England's great physicists
The RIM founder just kicked in another $50 Mil to his pet project:

Re:Go, open standards.
Nice way to keep the mean spirited issue at hand. You piss me off. I'm thinking that anyone whose web site is powered by Joomla http://www.perimeterinstitute.ca/en/Joomla!_License_Guidelines/ might actually take the hint if you kindly... KINDLY... ask them to produce the data in ODF formats.
Some of the people involved with this institution are well read and intelligent individuals. Talking like an asshat about them is not exactly an encouragement after all.
The content was put in a modifiable format, that's half the way there.

Reality checkFirst, this is unpublished work (i.e., there has been no formal peer review): it was presented at a conference.
Deutsch himself did not present, according to the speakers list. The New Scientist mentioned his collaborators Wallace and Saunders, who presented the following talks: David Wallace
Probability in the Everett interpretation: state of play
I will review the current state of the probability problem. My main focus will be on the attempts by David Deutsch and myself to provide a proof of the Born Rule starting from Everettian assumptions, but I will also attempt to locate these attempts within the more general framework of the probability problem. Simon Saunders
'The Everett interpretation
I shall present an overview of quantum mechanics in the Everett interpretation, that emphasises its structural characteristics, as a theory of what exists. In this respect it shares common ground with other fundamental theories in physics. As such its appeal is conservative; it makes do with the purely unitary equations of quantum mechanics as exceptionless and universal. It also makes do with standard methods for extracting 'high level' or 'emergent' ontology, the furniture of macroscopic worlds, from largish molecules on up. It would appeal all the more if it made do with standard epistemological principles too - for example, in the context of inductive statistical confirmation, with standard Bayesian epistemology. But this links to the question of the interpretation of probability in the Everett interpretation, and here the theory seems anything but conservative. It is a common complaint that the approach leaves no room at all for talk of uncertainty. I shall argue, again on conservative interpretative practises, that this claim is incorrect. Chance events are, indeed, revealed in a surprising light - as quantum branchings - but they are the more perspicuous, and their properties and quantitative measure better explained, in light of that. Neither one of those abstracts sounds like it is giving any theoretical or experimental support to the "many worlds interpretation" over other interpretations. At best, they purport to show how MWI is compatible with probability theory — a far lesser claim.
Indeed, it is impossible to give Everettian MWI any precedence over other interpretations, because by construction Everett made the MWI experimentally identical to conventional interpretations of QM.
Deutsch is famous for claiming that MWI is empirically distinguishable from other interpretations, but again, this is not actually possible. You have to read the fine print. I read one of his books years ago where he made that claim, and IIRC there was some footnote which explained that he wasn't actually talking about Everett's MWI, but some modification of quantum mechanics he has proposed which is compatible "in spirit" with the actual MWI. Well, fair enough, but it's not really legitimate to claim that he's talking about the MWI anymore: he's talking about his own theory (which has no experimental support). -
Re:Where is the paper?There was a conference on "Many worlds at 50" this past weekend at the Perimeter Institute in Waterloo, Ontario. I'm guessing that the most relevant presentation is "Probability in the Everett interpretation: state of play" by David Wallace.
Here's the talk's abstract: "I will review the current state of the probability problem. My main focus will be on the attempts by David Deutsch and myself to provide a proof of the Born Rule starting from Everettian assumptions, but I will also attempt to locate these attempts within the more general framework of the probability problem."
The talk can be viewed here.

Those wacky physicists!
I heard it was a practical joke gone bad at The Perimeter Institue. Apparently, Lee Smolin was preparing synthetic black holes for the string theorists' offices, and one of them escaped and headed for RIM's control centre.

Perimeter Institute
The Perimeter Institute has been putting its lectures online for some time now.
http://www.perimeterinstitute.ca/
Now I agree that it's good to have a central location for this sort of thing, but its hardly revolutionary. -
Perimeter Institute
Lee Smolin is on the faculty of the Perimeter Institute for Theoretical Physics which has an excellent public lecture series on physics and other scientific subjects. I have attended many of these lectures and they are always fascinating. These lectures are recorded and are available on PI's website in Windows Media format.

Re:Do we need quantum bits?
On the other hand, a future which offers quantum computing may also provide unclonable encryption and quantum key distribution, which I understand is more secure than current encryption methods.

Re:Thank you GOOGLE!!!!!
There are many countries other than just America where you can make it big on stock options. For instance, the Perimiter Institute was founded on the basis of the stock options of the founders of RIM. There is nothing uniquely American about the dream of making it big on the basis of your innovation and hard work.

Re:How Immediate is Immediate?
According to this page, Quantum Key Distribution is a multi-step protocol which goes at the speed of the wires. It appears to be immune to eavesdropping, but not to a man-in-the-middle attack.

Re:Won't work...
Right. But well, some people have attempted to develop quantum authentication protocols like this one, this one, and this one. Dunno if the device in question does any of them, or even if any of them are actually practical to use with today's technology. If the device in question doesn't use quantum authentication of some kind, well, they're selling snake oil, but I wouldn't dismiss the whole concept of quantum cryptography out of hand totally the way you seem so ready to.
