Weren't the hidden variables intent exactly to keep the theory local?
No, the hidden variables were to keep the theory non-probabilistic. In other words, if you really knew what was going on (the state of the hidden variables), you would not need the quantum wave-function. Bell's Theorem showed that there were observational consequences of this, and tests of Bell's Theorem have showed that the universe follows Bell's Theorem. So, this means either that there are no hidden variables, or that there are hidden variables, but the universe is non-local. (In other words, the universe cannot both be local, and have hidden variables.)
Most people weren't willing to throw out locality just to avoid dealing with spooky quantum entanglements. But, if there is a need for non-locality anyway, then
- the use of Bell's Theorem to rule out hidden variables falls to the ground and - hidden variables seem mild compared to the consequences of non-locality,
so I think a resurgence of hidden variables is inevitable.
Note, by the way, that the biggest argument against faster than light travel is that it would cause causality violations. With non-locality, that objection falls to the ground, and (for the science fiction writers out there), FTL becomes much more respectable.
All of this is a lot of weight to put on a 95% probability. I won't believe it until its 5 sigma.
The Greenberg et al 2002 paper says that CPT violations imply theories that are not Lorentz invariant, but also that :
Theories that violate CPT by having different particle and antiparticle masses must be nonlocal.
Now, the various EPR tests have shown that quantum mechanics cannot have a local hidden variable theory. So, if these results are true, I would expect to see a resurgence of hidden variable theories, of a nonlocal nature. Maybe they can even be clever and figure out how to how to do it in a way that preserves causality (as nonlocal theories in general imply that causality violations - i.e., time travel into the past - are possible.
This was discussed a lot in 1996 in the IETF NewDom Working Group, which I participated in, and which partially lead to the creation of ICANN. What a zoo that was - it ended with Eugene Kashpureff going to jail for attacking the DNS root servers. For some reason, ".xxx" seemed to drive people crazy, and I am not sure it is much different today.
So, if the public domain is taken away from people who are using it in their business, isn't that a taking ? Since my company uses public domain videos, who do I apply to for money to compensate me ? (This would fit right in with recent Supreme Court rulings concerning takings.)
I use desktop machines purely for CPU now-a-days; my time (except for data-wrangling) is spent on my laptop.
By the way, was I the only person who thought that "Flight of the Desktops" was going to involve, you know, actual desktops actually traveling through the air ? Suckered me in.
I understand the rational here, and I am sure that these inspections were originally done to guard against both casino and player malfeasance. However, it is very easy for this good purpose to slide into a protect-the-corporation racket. Again, if there is evidence that there is trickery, prosecute, but if there is not, I think that the casino should pay.
To put it another way, I trust neither the corporation, nor the state gaming commission, to be on the side of the citizenry.
"It's the second time in three months a Colorado slot machine has made a multi-million dollar mistake. In March, a machine malfunction was blamed for a $42 million dollar jackpot."
Look, if they found evidence of fraud or tampering, throw the book at them. Otherwise, them's the breaks - pay the couple.
The casino deserves to be pilloried and lose their gaming license over this. It's bad enough you can be ejected or even banned for being too good at playing something. Now, it seems that they are extending this to games of chance. This seems a little too pat, as the casinos could avoid ever paying out anything by simply making sure that their slots always have some technical flaws.
There is no civil society in Antarctica - none. I do not believe that there is as much as a convenience store in the entire continent. So who, pray tell, is getting the money from these calls ? The National Science Foundation ? Now, that would be an interesting way to expand the science budget...
I watched the Reagan administration destroy the large Carter administration solar power program at JPL in 1981, so this does not surprise me at all. They literally did not want any competition for petroleum.
I want that guy's name off of National Airport in the worst way.
Given that we are talking about one Rupert Murdoch web site, this title is bad even for slashdot. The Times of London used to be an important paper, comparable to the New York Times. Then Rupert Murdoch bought it, and it rapidly ceased to be significant. (As far as I can tell, any news organization taken over by Murdoch rapidly ceases to become a significant news organization.) To say that this is all of the British press going silent is simply ridiculous. Try reading the Independent or the Guardian if you want a taste of the British news that is not going silent.
I can remember very vividly GM and Ford (and Chrysler and even Packard) saying basically the same things about cars - they could put in safety features, but they didn't because there was no customer demand for it. This was, mind, when cars had metal dashboards and spear-your-heart driving wheels. This went on until the Federal Government started forcing changes, and until Volvo and other foreign manufacturers started making sales touting safety. I expect to see a similar story arc about piracy on-line.
That won't invalidate the patents though, after all how many millions has MS and various other large companies been paying out in court to small patent holding companies?
Well, it might invalidate their patents. That can happen if you sue. But, that is not the real risk to a company like ON2. If they sued over H.264 you can bet your boots that someone, probably several someones, from the MPEG-LA patent pool would sue ON2 for patent infringement. And, not just on the patent of the original suit, but any patent in the big company portfolio of thousands of patents. If you sue, no RAND terms for you, so tech they thought were safe would turn out not to be.
A patent attorney told me once that suits like this require a multi-million dollar down payment. Each. This would literally be a "bet the company" move for ON2 (as in, if they lost, they might have to shut the company down), so the chances of it happening are basically nil.
The companies you mention don't actually have a business - except suing people. So, if they lose, they lose a patent, or maybe just a patent claim, but they don't have to shut down. That makes it harder to counterattack, and more likely for the victim to settle.
Yes, I noticed that. However, this is back-of-the-envelope, and being off by a factor of 3 is quite acceptable IMHO. If you use a radius smaller by a factor of X, the radiation load on the skin goes up by a factor of 1/X, in this crude model, so this just makes the problem worse.
The stated dose — about.02 microsieverts, a medical unit of radiation — is averaged over the whole body, members of the UCSF group said in interviews. But they maintain that if the dose is calculated as what gets deposited in the skin, the number would be higher, though how much higher is unclear."
Well, a quick back-of-the-envelope calculation says it could be a lot. Suppose you model a person as a cylinder 2 meters high by 1/2 meter across. The volume is 0.4 meters^3, the surface area is 3 meters^2. If the skin is 0.1 mm thick, then the volume of the skin is only 0.0003 meters^3, a factor of > 1000 smaller. So a dose of 0.02 microsieverts for the whole body would be 25 microsieverts for the skin.
If you read the original article, a chest X ray is about 100 microsieverts, but of course that is absorbed in the body, not the skin. Radiation therapy causes skin "burns", but I couldn't find in a quick search the level of radiation absorbed by the skin to make that happen. However, if this is a problem as indicated, then flying one round trip per week (100 flights/year) would mean an exposure of order 2500 microsieverts, or 25 chest X rays, a level I don't think Doctors would be comfortable with.
MPEG-7 is not a video standard. MPEG-7 is a content description standard, developed starting in 2002, and without a phenomenal deployment. Having the ability to add metadata at the frame level would be a great boon to video editors, but from reading the article I have no clue what MPEG-7 has to do with their digital signature scheme, or why they think Yet Another Digital Signature Scheme will achieve what all of the previous Digital Signature Schemes have so obviously failed to.
So, it had a magnetic field, presumably from a core dynamo like the Earth's. To me, the question is, did the core dynamo die some long time ago, or is Mars currently undergoing a magnetic field reversal, as the Earth does regularly (i.e., was had a billion years ago, or a few thousand) ? The vast consensus is that the Mars magnetic field died a long time ago, but I think it is more provocative to hypothesis an ongoing field reversal, and see what observables could come from that.
I am pleased to say that I helped get make those finding possible, by going to various people at JPL with a colleague (Bruce Bills) and pressing all and sundry to get the DSN to range to Pathfinder after landing, specifically to improve the precession constant and determine this.

I think you are correct. In 96 or 98, this would have been like minting money. Now, not so much.

That would save the State of California $ 60 million per year it doesn't currently have.

not much of a magnetic field
Well, that is an interesting point. It has a liquid core. It has a fair amount of magnetization of its surface.
So, it had a magnetic field, presumably from a core dynamo like the Earth's. To me, the question is, did the core dynamo die some long time ago, or is Mars currently undergoing a magnetic field reversal, as the Earth does regularly (i.e., was had a billion years ago, or a few thousand) ? The vast consensus is that the Mars magnetic field died a long time ago, but I think it is more provocative to hypothesis an ongoing field reversal, and see what observables could come from that.
I think one of the bigger issues is that Mars doesn't have a molten core,
Mars does have a molten core, which was shown by the combination of Viking and Pathfinder tracking data.
