sure, this is good practice. but if you don't know, or are too distracted to notice it is still not your responsibility. being a text, it seems reasonable to assume that the receiver will read it when it is appropriate to do so.
There is a catch, however. The procedure they use is entanglement swapping. Unless there has been a new version of it, it works in the following way.
The photons of the pair 1 are sent to Alice (1A) and Victor (1V), they are entangled, the same for phtotons from pair two that go to Bob (2B) and Victor (2V).
Victor now has to entangle 1V and 2V so that 1A and 2B are entangled as well. He has to do this without knowing the initial state of 1V and 2V though because, being entangled to others far away, they look as random to Victor.
The only way to take an unknown state of two qubits and end up with an entangled state is violating unitarity. In particular in means that you will use at least one measurement and discard the whole thing if it gives the wrong result.
In this setup not all the pairs 1A and 2B where Victor tries to entangle are correlated, only those where he succeeds. So whatever set of 1A,2B results you choose, Victor's procedure will select a subset of them that is correlated.
The use in the first pages of the paper of the word "project" for the operation of Victor makes me think this is the case. I did not bother checking properly because I am lazy.
You think there were no US casualties from the bombings of Hiroshima and Nagasaki? How naive... There were prisoners of war.
Maybe only 11 of your soldiers are not worth giving up the opportunity to massacre the civilian population of an entire city. They could have dropped it on a deserted island, with warnings and it would have been just as effective in order to strike fear.
If Japan had used an atomic bomb and then lost the war anyone involved would have been tried and executed Nuremberg style. But US won the war, then it became fair game.
There is no particle-wave duality. Every particle is only a wave and sometimes, if you look from very far (or at high temperatures) it seems to behave as a point-like object.
In any case it is not like path integrals are alternative to the normal schroedinger wavefunction formulation. See the work of Dyson for that, or simply the Feynman-Kac formula. At the fundamental level path-integrals ar just combinations of double-slits experiments in a very abstract space (Trotter's formula).
And yes, in the path integral a particle interferes with itself. You'll notice that you have to take into account and sum paths going through different slits.
I do work in the path integral formulation because I think it is more elegant, but it is not an alternative to the "traditional" wavefunction approach (hey, path integral is not exactly new anymore). It is the same as choosing cartesian or spherical coordinates.
The tagline is: path integrals do not describe different physics.
I believe the difference from the fullerene is that they are detecting the single particles here, instead of a stream. In this sense they can really show that each particle interferes with itself, since while one molecule travels to the screen there is no other particle to interact or interfere with.
Among the last few generations of physicists it is generally believed that everything is quantum from an elementary particle to whole planets. It's just very difficult to cool planets down to where the thermal length is smaller than their de Broglie's length. Not to mention creating a coherent planet gun and detector... But there was no reason to believe it is fundamentally impossible.
Fully agreed. The biggest threat to whales was to be used to polish shoes, not to be eaten. Those species that did not pass the point of no return should be growing in numbers by now, regardless of current whaling.
Besides, these assholes (that do not dislike causing physical harm to people, to the point of causing permanent injuries) manage to unite and polarise the public opinion in Japan in support of whaling, where normal people usually does not care the least.
They are despicable and people giving them money are supporting criminals. Remember that even Greenpeace calls them terrorists and hides information about whalers' locations to Sea Shepherd.
Finally, whale meat is terrible, no one likes it and in Japan it mostly ends up in pet food. If no one made a fuss about it, whaling would be gone in a couple of decades. Like this it becomes a token battle for the far right and a question of national pride.
Do you really see no problem in trying to find a warming trend by comparing only the warmest years? Do you also measure the average human height by looking at NBA players?
The statistically significant information from that table is that the last 11 years are all in the top 15.
So they think it is wrong because it reveals the test scores? Are they insane?
First let's say why it is really wrong: because it identifies the student with the his performance and starts to dehumanize him, it could be mortifying and alienating if the student does not have a really strong character. Even more, who is to say that failing badly would not give you a BETTER reputation with students? In a school for lower class childrem having good scores could become a stigma, could lead to cheating, harassment and god knows what else.
But peer pressure IS important for education. I dream of a school where students think it is cool to have good scores, where a student can learn the importance of culture in a relatively innocuous way before his first job interview bites him.

Not really to hurt Wikipedia. Our beloved Prime Minister has the habit of speaking with mafia members (the real one, not the one with two As) and other criminals, that are usually wiretapped (while he is immune from wiretapping). In this records he reveals damning details about his life (and some things that could be crimes, but that is not very important). He wants to keep this information from the public, since he surrounds himself with prostitutes (possibly minors) and such. Even his voters are not thrilled to hear that he considers being a prime minister "a hobby", as he told one of his prostitutes.
If you are referring to Cesare Battisti, hed nominated his lawyers and sent testimony to his trial. He also had the option to attend the trial any time, but decided not to. The trial was deemed just by the EU supreme court: he should be in prison by international law.
There have been and there are many wrongs in Italy but this is not one. The discredit that we erned with the current politicians hurts us even when we are in the right.
Not to mention that if they have a problem with their measurements they would like to find it before they publish something that is wrong for the same reasons but not as clearly wrong. People would take it as valid for a couple of decades or so before the experiment is repeated.
One minor point is: they did not measure the speed of light: you are right that you can only measure that with photons. They have measure the speed of neutrinos and found it to exceed the speed of light. Even if the finding is true it does not change the speed of light, it only invalidates the assumption that it is the maximum possible speed.
The Romans had this habit of actually conquering the land and giving it to soldiers. The soldiers fought better because they could get rich and have nice estates and the land was going to be part of the empire and pay back the debt soon. No modern state can do that now unless it can take all the rest of the world in a war at the same time. Imperialism is not an option anymore.
Also of note that the Romans went to great length to justify every war of aggression so that it could be considered "just". From "did not pay us a tribute" to "did not respect our gods" to "called our moms fat", every war was seen as a just and proper retribution for a horrible crime.
WTF? If you design something with cross-desktop in mind, or even just a shared KDE-GNOME technology, it is much more likely that your work will be well engineered and will stand the test of time, even if you end up being the only one using it.
What about this: Cisco and Adekeye agreed that the court proceedings would be held in Vancouver from 18-20th of May because he was denied visa. On 19th they filed the criminal complaint alleging that he was likely to flee after the hearing. The Canadian authority was not informed that the hearing had a legal value and interrupted it so that in the end Adekeye could not testify. Talk about good timing...
Also of note that the judge was outraged as well at the US Secret Service, since all this ploy could not be effected without the help of the sovereign state.
As I understand it: in the last year this guy could not leave Canada, meet his family in Switzerland nor work. All because the USSS decided to give a hand to Cisco in smearing him and paint him in a bad light for the antitrust trial. I would be surprised if the judge was not outraged.

insightful? are you kidding me?
Two people lost their legs because the asshole was texting. I'd give them a pass for being a little cranky and suing around!
That an AC could be a sociopath devoid of any empathy is par for the course, but mods, really?
sure, this is good practice. but if you don't know, or are too distracted to notice it is still not your responsibility. being a text, it seems reasonable to assume that the receiver will read it when it is appropriate to do so.
would not work :( as I wrote in http://science.slashdot.org/comments.pl?sid=2808465&cid=39792565
notice that after the comment I did verify in the paper that my expectations were correct.
the short of it is: trying to entangle photons will not always succeed. The procedure will succeed more probably when A and B have seen a correlation.
This is exactly the apparent paradox.
There is a catch, however. The procedure they use is entanglement swapping. Unless there has been a new version of it, it works in the following way.
The photons of the pair 1 are sent to Alice (1A) and Victor (1V), they are entangled, the same for phtotons from pair two that go to Bob (2B) and Victor (2V).

Much less paradoxical, don't you think?
First they ignore you, then they ridicule you, then they fight you, then you win.
To me this seems more like the "denial" phase in a different but still well known sequence.
You think there were no US casualties from the bombings of Hiroshima and Nagasaki? How naive... There were prisoners of war.
Maybe only 11 of your soldiers are not worth giving up the opportunity to massacre the civilian population of an entire city. They could have dropped it on a deserted island, with warnings and it would have been just as effective in order to strike fear.

nevermind trascendental, did he ever hear about irrational?
But they give approximately one BE dose of radiation.

Newton was already well aware of the equivalence. You don't need Einstein's relativity for that.

up to 99 of each type, maximum one type per letter of the alphabet, obviously!
But seriously, identify and recall are the must-have and 10-20 is really a minimum until you get something to replace them.
But, but, but... shareholders!
Shareholders should seek relief against those that they entrusted to run the company profitably, which includes not getting bankrupted by fines.
