It looks like quantum teleportation meets delayed choice.
It would be nice if they'd also do something about the remote sensing infrastructure to get more data to these nice new supercomputers. My current understanding is that the Feds are getting increasingly weak in that department.
This will definitely give the bio-ethicists something to chew on.
A friend of my in the 70's who was a math grad student at the time was playing with taking the absolute value of gamma = 1 / sqrt(1-v^2/c^2) to avoid the imaginary aspect of the term. Only at light speed was a massive particle forbidden. The square of the momentum remains real. Other results were the same: Things become less energetic the farther you get from light speed in either direction. At sqrt(2) times c, your relativistic mass and time are the same as at rest and your subjective trip time matches that of distant observers. Finally, at infinite speed you have zero mass and your subjective trip time is the same as the distance traveled (times c, of course). I seriously doubt my friend was the first person to come up with this. What's different with the new publication, AFAICT, is that these guys have an eager university press office. I love it when the press release folks feel obliged to mention that the work appears in a "prestigious" journal.
I've seen many Slashdot posts that are copy/pastes of press releases, so what's new. I follow eurekalert.org, and have been really appalled at times at the low quality of the reporting.
I'm curious what's going on such that the top is heavier than the Higgs rather than the other way around. All I've been able to find is people asking why the top was found first. *That* I understand--the Higgs signal is much much smaller. I remember something from long ago about the top's mass "leaking," if you will, to the the lighter particles, but that doesn't mesh with how I understand the Higgs mechanism. Anyway, I would expect the Higgs particle manifestation to be the most massive of those that participate in the Higgs field.
Not so strange. Space.com is one of many more or less hermetically sealed news sites.
K7DAN writes "North Korea warned South Korea on Sunday of 'unexpected consequences' if Seoul displays Christmas lights near the tense border, and vowed to retaliate for what it called 'psychological warfare.' From the article: 'The tree-shaped, 30 metre-high steel structure on Aegibong hill - some 3km (2 miles) from the border - was illuminated by thousands of small light bulbs last year. It could be seen from the North's major city of Kaesong across the border, according to media reports. Pyongyang has previously accused Seoul of using the tree to spread the Christian message to people inside the secular state.'"
It will be cool if the experimental permit works.
I can't decide if the question is about what punishment he should get as opposed to what punishment he's likely to receive. Legally I think they could go for the death penalty. I hope they don't.
Slashdotting + Ad click revenue => $$$
The actual "FA" is here, with images. Gigan, et al. say, "opaque materials."
John Mauchly, who knew a thing or two on the subject, made the same observation in a conversation that touched on the issue. It wasn't so much that Babbage was pushing the day's technology too far, he just never froze his design.
I bought a new battery for my Vaio laptop. Since it wasn't the exact same model (A/B instead of A in the part number suffix), a BIOS upgrade was necessary. The instructions included the appropriate warnings about not turning off the computer until completion. It got to what it said was part way through its verification phase and hung...and hung and hung. Even the power button stopped working. I was lucky that someone had the same model in the shop so I was able to get my data off the internal RAID0 drive pair.
