String theory put to the test

String theory is arguably the most popular theory in theoretical physics; that is, it cannot be proven. The idea, is everything you see around you is made up of tiny strands of energy that vibrate at different frequencies. Until now, experimental verification has not been possible; but researchers at the University of California, Carnegie Mellon University, and The University of Texas are planning a definitive test with the future launch of the Large Hadron Collider in Switzerland that could disprove the current theory.

Similar to the well known U.S. particle collider at Fermi Lab, the Large Hadron Collider, scheduled for November 2007, is expected to be the largest, and highest energy particle accelerator in existence; it will use liquid helium cooled superconducting magnets to produce electric fields that will propel particles to near light speeds in a 16.7 mile circular tunnel. They then introduce a new particle into the accelerator, which collides with the existing ones, scattering many other mysterious subatomic particles about.

It is with this accelerator, that will allow researchers to begin observing the scattering of W bosons, an elementary particle that is one of the four fundamental interactions of nature and required in the proposed testing of the current string theory. I use "current" because string theory is just that, a theory; and it is constantly changing as more information becomes available.

"Our work shows that, in principle, string theory can be tested in a non-trivial way," said Ira Rothstein, co-author of the paper and professor of physics at Carnegie Mellon.

"The beauty of our test is the simplicity of its assumptions," said Benjamin Grinstein, a professor of physics at the University of California "The canonical forms of string theory include three mathematical assumptions — Lorentz invariance, analyticity and unitarity. Our test sets bounds on these assumptions."

Grinstein also noted that if their test does not substantiate what the theory predicts, one of the key mathematical assumptions about the current string theory would be incorrect."

Isn't standard email outdated?

Submitted by Anonymous Coward
An anonymous reader writes "Telnet was replaced by SSH for obvious reasons. Why hasn't standard email been replaced? There are more problems associated with standard email than there were with using services like Telnet, yet we managed to sweepingly switch out Telnet for SSH. Why not dump standard email for a better messaging implementation? We could cure SPAM and privacy issues in one fell swoop."

Pornographers Could Play Kingmaker in HD DVD Wars

Submitted by
Carl Bialik from WSJ
Carl Bialik from WSJ writes "The adult-entertainment industry could play a big role in deciding whether Blu-ray or HD DVD wins the battle of the high-definition DVD formats, the Wall Street Journal reports. From the article: 'Replicators — the companies that stamp out DVDs — lie at the heart of the matter. Setting up shop to manufacture HD DVDs, which run on very similar production lines to regular DVDs, is easy and inexpensive. Blu-ray requires significant investments in new equipment, and the individual discs in that format cost more to make. Because manufacturing adult-entertainment DVDs isn't as lucrative overall as stamping out titles for mainstream studios, the specialty companies that replicate for adult-entertainment companies don't always have the same resources to gear up for Blu-ray.'"

Swedish bill to sniff internet traffic presented

Submitted by
swehack
swehack writes "The Swedish defense minister today presented a bill(Swedish) to let FRA(National Defence Radio Establishment) listen to all internet and radio traffic sent over Swedish borders. Internet service providers will be forced to allow access to their border points where FRA will be allowed to filter for certain search patterns. The search patterns the FRA will filter traffic for will be decided by the FRA. The swedish minister of defense, Mikael Odenberg, noted that the bill only applies to outsie threats, information transferred between two swedes will not be used."

Dynamic Filesystem For Spotlight Searching

Submitted by Anonymous Coward
An anonymous reader writes "Hot on the heels of Amit Singh's release of MacFUSE some days ago, now Google software engineer Greg Miller has coded up a nifty MacFUSE filesystem called SpotlightFS in his spare time. In SpotlightFS if you try to go into a folder or "ls" it in the Terminal, you see links to actual files and folders which are the result of dynamic Spotlight query! You doubleclick on these links and they open up nicely. Not only that the filesystem picks up Apple's "saved search" (smart folders) and shows them as real folders too. You can do cool things like creating a new folder called "pdf" (or some advanced query) and you will see inside all pdf query results from Spotlight. The projec's wiki has more details. And when you eject SpotlightFS these folders don't go away so I can have my favorite searches neatly arranged in a filesystem. SpotlightFS is up for download at the project web site."

I enjoy the time that we spend together.
