Microwaves do chemistry, what about cell phones?
Clearly, the specific properties of the microwaves used (not just the heating) cause specific chemical changes in the plastic and rubber compound. Essentially, polymer chains are being broken up. But we as consumers are told not to worry about microwaves from cell phones, WiFi, or base stations.
Why? Well, the photon energy (Planck's constant times the microwave frequency) is too low to cause chemical changes. All microwaves are supposed to do to tissue is a small amount of heating. Yet clearly, other processes that damage polymers can go on as well. DNA is a polymer, and breaks in DNA induced by EM fields is exactly what Lai and Singh at Washington state university have found. Their work has been surpressed: http://www.washington.edu/alumni/columns/march05/

Re:This just in...The University of Washington is heavily subsidized by the government. While you are correct that tuition fees only make up 12% of the budget, according to the (PDF) University of Washington's 2006 Report (PDF) (Page 20), State funds amount to only 11% (capital and operating combined). The students aren't paying for bandwidth, taxpayers are paying for bandwidth, and I can guarantee you that they aren't paying for the bandwidth so that college students can distribute the latest pop albums. As another poster mentioned, students also pay for internet access. At U of W, it would appear to be included with rent.

Getting to work
Don't people have to get to work somehow?
Telepresence. See the Wikipedia telepresence article.
"We must imagine a future without cars."
Designing a city without any cars.
Orson Scott Card on 'walking neighborhoods' (I first thought he was talking of some scifi idea, such as moving neighborhoods, haha.)
Carfree (?)
Monorail Opportunity in Seattle, Washington (1998)
From #19302663:People got along for thousands of years without cars, so maybe you should consider getting rid of yours.
Also, from #10313790:
This is what I think... There won't be cars in the future. There will only be personalised vehicles to transport each individual. Roads, the larger they are, will not allow single vehicles. There has to be two or more (depending on the road) vehicles required to travel together. Probably the smallest road will allow individual vehicles to travel by themselves. As more vehicles travel together the overall fuel consumption will decrease and fuel efficiency will increase. Individual vehicles will be able to break off from this combined unit as they reach their destinations.
Creating car free cities dupe with >1k comments.
Post #5975896 gets it right:Even with "emission free" cars, you still expend the energy to move the car to being with. Getting rid of pollution is an important goal, but the ultimate goal should be to conserve the environmental resources required to produce and operate cars. By creating a city in which cars are less necessary, you reduce the energy consumption of the average citizen, even after you factor in the energy required to operate the 24-hour mass transit systems.
Just an interesting tidbit here: "It's things like cars that take people out of public spaces and make a community less safe."
Arcosanti, an interesting experimental town supposedly as an alternative to urban sprawl.
Argument that car-free is too expensive.
An interesting problem in #5975908:1) People like cars. Tell them they can't use thier cars anymore, and you're liable to be voted out of office.
2) If you get rid of cars, you have to have an alternative system of transportation in place. Unfortunately, the only place to PUT that system will many times be where the roads are now. Result: you can't build the system until the cars are gone, and you can't get rid of the cars until the system is ready!Apparently Venice is not the solution, either.
Small steps needed to make the change.

Re:Yay, Humans
Standing at the bow of a small open boat with an outboard motor with a non-exploding harpoon and a gun in your hand is probably one of the scariest experiences I can imagine. I've heard some really frightening tales from Eskimo whaling captains.
What is it with you and your "factory killing ships"? Are you some kind of nut? Or do you have Eskimo people confused with the Japanese "scientific" whaling expeditions?
Do some fucking research before you spout off with your nonsense. A Google search for "eskimo whaling techniques" brings up lots of good explanations on how whaling is done in modern Eskimo communities. From http://luna.pos.to/whale/iwc_chair06_6.html see "Regarding the Alaska Eskimo bowhead whale subsistence hunt, it was reported that subsistence hunters make every effort to dispatch the whale as quickly as possible to provide a humane death for the whale, to reduce the chance of losing the whale, and to reduce the amount of time hunters in small boats must spend in the frigid waters of the Arctic Ocean. It was further reported that the Alaska Eskimo Whaling Commission has undertaken an extensive program to upgrade the safety and humaneness of its traditional weapons used in the hunt."

This won't work
Disclaimer: I am a physicist working in a quantum information group, and have taken a graduate level physics course on quantum information.
This won't work. The article doesn't give details, but by googling the scientist, I found this proposal, and immediately recognized the flaw in the experiment. He's trying to use a quantum eraser (wiki of quantum eraser, and link to good article on them) to change the image of the downconverted photons on a camera, but that simply cannot be done. The image on a screen can be changed using a nonlocal eraser, but only when you look at conincidences of the two photons. This is a common proposal for FTL communication, I just can't believe no one ever told this guy why it wouldn't work.
The quantum eraser (linked above) can be pretty tough to get your head around. It combines interference, entanglement, and nonlocality, all tough nonclassical phenomena. Feel free to ask if you read the article and don't understand something. -

Re:Cramer, you say? Hmmm...
Look? John Cramer..., Cosmo Kramer, I don't think so...
But strangely there's some resemblance to the "real" Kenny Kramer (which the character Cosmo Kramer was based on)... -
Re:for chists sakeYou are right that standard QM prohibits FTL. However, Cramer is looking for a small nonlinearity - possibly at high energies - that standard QM doesn't account for and may provide a superluminal "loophole". From his article, Quantum Nonlocality and the Possibility of Superluminal Effects:
This prohibition against superluminal communication, as stated above, is a part of standard quantum mechanics. However, this prohibition is broken if quantum mechanics is allowed to be slightly "non-linear", a technical term meaning that when quantum waves are superimposed they may generate a small cross-term not present in the standard formalism. Steven Weinberg, Nobel laureate for his theoretical work in unifying the electromagnetic and weak interactions, investigated a theory which introduces small non-linear corrections to standard quantum mechanics [13]. The onset of non-linear behavior is seen in other areas of physics, e.g., laser light in certain media, and, he suggested, might also be present but unnoticed in quantum mechanics. Weinberg's non-linear QM subtly alters certain properties of the standard theory, producing new physical effects that can be detected through precise measurements.

USPTO Patent Lawyer Guidelines
If the USPTO wants to start dealing with software more, they are going to need to change their bizarre rules for who can sit the patent bar.
Currently, the USPTO only allows attorneys with certain undergraduate degrees to sit the bar. Many are engineering degrees: electrical engineering, civil engineering, ceramic engineering, etc. Some are more general: biology, general chemistry, food technology, etc.
Computer science is also one of the degrees listed, but there is an asterisk next to it. CS is the only degree which the USPTO requires accreditation on. Why is this significant?
Because most of the best CS schools in the country don't even have accredited CS programs. I ran down this list one time. Out of the top four CS schools only two, MIT and Berkeley, were accredited. Only 3 out of the top 10 were accredited and 6 out of the top 20. Most CS departments feel that accreditation is absolutely worthless. Employers don't care, the accreditation process doesn't focus on CS education as much as other non-majored courses students must take, it is expensive, and it is not valuable to the student.
Consider this: a lawyer with a CS degree from Pacific Lutheran or St. Cloud State (ranked sub-100 in computer science) can sit the patent bar, a lawyer with a CS degree from Stanford or Carnegie-Mellon (top 4 schools) cannot.

Transactional interpretation isn't crazy
This guy isn't crazy, the idea of using advanced waves goes all the way back to Feynman (see Wheeler-Feynman absorber theory which is what this is based upon). This merely another interpretation of Quantum Mechanics. All he's trying to do is see if we can experimentally verify it as producing different results than the "standard" interpretations. It's called science people, look into it. Sometimes crazy ideas turn out to be true, you don't know until, you know, you run experiments. As crazy ideas go, this one isn't that off the wall, it's based on actual physics. There's no FTL involved, the transactions all occur at the speed of light through advanced and retarded waves.

Not just released, but still awesome
This system was demoed a while ago, I think at siggraph 2006. There are some videos on the original university of washington "PhotoTourism" research page. Also here's a repost of the same video on that page on youTube.
Also there's microsoft's photosynth page, which has the demo (it's been up for months). It seems to have some longer videos.
Non-newness and marketing hype aside, this software is frickin' awesome. It lets you view and tag photos organized in a 3D environment that reflects where the photos were taken. It should be particularly useful once cameras have GPS built in. It could be used by a single person, but it's definitely well suited to large collections such as flickr. I imagine the reason the software is still in the demo phase is because it's very difficult to take a large number of photos and reliably figure out where they were all taken from. For the demo purposes, Microsoft probably hand corrected a lot of the placements. Even so, everyone I've shown this to thinks its awesome (even non-slashdot readers!). -

Re:Whatever
>and why the "carrot" is often so bogus
It might be bogus and it might not be bogus.
The patent system went way overboard over the last 20 years to strengthen patents because of the lack if investment in R&D in the 70's.
Now with the pendulum swinging the other way the question is will it hurt R&D spending again and thus economic growth (innovation is the impetus for growth).
"
In the late 1970's, U.S. industry believed
that Japan had beaten the U.S. in terms of technology
innovation. The Japanese system, policies,
and corporations were seen as very successful. The
U.S. keenly realized that they needed systematic
reform to regain international competitiveness.
Towards the end of the Carter Administration, the
government and private sector reached a consensus
that the U.S. was in an "innovation crisis" and that
U.S. technology innovation had slowed down. In
such an environment, a variety of reforms were
carried out. These included the establishment of
the Court of Appeals for the Federal Circuit
(CAFC), reform of the patent laws, strengthening
of the United States Patent and Trade Office
(USPTO), enlargement of the scope of patent protection,
transfer of federal R&D results to the private
sector, and integration of trade and patent policy.
These reforms might not have been carried out if
U.S. industry had not recognized that it was in an
economic crisis.

Note that this is NOT the same as saying that time has a direction or even a flow, but more that there is a point that moves along the gradient. Put another way, if I am just a set of points in 4 space, why should one point be favoured over any other? -

Re:Man, what a manipulative way of putting thingsSorry, no agenda here beyond the fact that no country came out of WWII clean (I'm not Russian at all by the way). Stalin was a genocidal maniac who treated the Baltics no better than the rest of the USSR. I just object to this claim of being completely innocent. Of course everyone said they were just following orders. Even the German soldiers said they had no choice. I truly doubt that the atrocities, such as Lithuanian death camp guards (i.e. Majdanek), were done without any choice. Obviously the Nazis and Soviets were the driving force behind the worst events but they needed some willing participants to do so.

Re:Not at all clueless
The only way to both allow binary drivers and maintain stability is with a microkernel based design, where the drivers run sandboxed and can fail without taking down the whole kernel. Monolithic kernels will never have that sort of stability, but they are faster and far easier to understand. So it's a trade-off.
Nice post, but I have a quick comment about the above. Check out the Nooks research project out of the University of Washington: http://nooks.cs.washington.edu/
They managed to sandbox Linux drivers using page protection techniques. A driver cannot, under most circumstances, bring down the kernel. -
Re:Makes a little bit of sense. . .
I'm not sure if the guidelines vary by country, but the U.S. guideline was 15 compressions for every 2 breaths (5 + 1 if two people are working). The guidelines were changed to 30 + 2 at the end of 2005. The reason for the change, as others have mentioned, is that the circulation of blood is most important. Rescue breathing takes time, is harder to do correctly than chest compressions, and takes time (consider it an operational overhead). Also, the compression of the chest causes some air movement on its own, though it is shallow.

Re:Japan gets maglev trains, we get a war in Iraq
You got me curious, so I did a little math.
Cost of the war so far (not counting amount we'll waste before this blunder is done with): $420B.
Cost of superconducting maglev track per mile in the US for long distances: $15-20M. Let's say 20M.
Miles we could build: 21,000
Distance across continental America, east to west: ~2500 mi
Distance across continental America, north to south: ~1250 mi
For that money, we could build ~5 east-west cross-country routes and ~7 north-south routes, or 4 and 9, or whatever. Another way to put it: we could add almost half of our entire length of interstate highways in superconducting maglev. Other methods, like inductrac, could be much cheaper and cover more miles.
Or, we could use the money to kill a bunch of brown people overseas for no good reason. Either way works, I suppose. -
Transactional Intepretation rulesAll these problems of observers, and reality and whether it's really real all go away if we make one very simple assumption: some particles can travel faster than light (and therefore backwards in time).
Wikipedia gives a brief introduction> but the main paper is quite readable.
To me it just seems right. The Copenhagen interpretation seems to be driving itself into an unsatisfactory corner. And which is more likely? We've got a tweisted view of it for 70 years, or the universe can do something unexpected with time travelling waves? Just that one little mental hurdle to cross, and everything else falls into place. No more spooky actions at a distance. No more photons knowing which slit was closed after they had gone past it.
-
Re:bye-bye!
Bohm's interpretation isn't the only alternative to the standard Copenhagen interpretaion. The "many worlds" interpretation is popular with science fiction (such as Stargate SG-1). There is also a "transactional interpretation" by John Cramer. It invokes interactions between the future and the present, just as there are also ordinary interactions between the past and the present. And here is something that calls itself (only at the end of the file) an "aethereal interpretation". It starts by talking about all those "virtual particles in the vacuum", and saying, let's call that thing "the aether"... and goes from there.
