FBI Orwellian Cyber Police State: Citizens Not Allowed to Have Secrets

""The police and surveillance state predicted in the forward-looking 1940s classic "1984" by George Orwell, has slowly, but steadily, come to fruition. However, like a frog sitting idly in a pan of steadily-warming water, too many Americans still seem unaware that the slow boil of big government is killing their constitutional liberties.

The latest sign of this stealth takeover of civil rights and freedom was epitomized in recent Senate testimony by FBI Director James Comey, who voiced his objections to civilian use of encryption to protect personal data – information the government has no automatic right to obtain.

As reported by The New American, Comey testified that he believes the government's spy and law enforcement agencies should have unfettered access to everything Americans may store or send in electronic format: On computer hard drives, in so-called i-clouds, in email and in text messaging – for our own safety and protection. Like many in government today, Comey believes that national security is more important than constitutional privacy protections or, apparently, due process. After all, aren't criminals the only ones who really have anything to hide?

In testimony before a hearing of the Senate Judiciary Committee entitled "Going Dark: Encryption, Technology, and the Balance Between Public Safety and Privacy" Comey said that in order to stay one step ahead of terrorists, as well as international and domestic criminals, Uncle Sam's various spy and law enforcement agencies should have access to available technology used to de-encrypt protected data. Also, he believes the governmentshould be the final arbiter deciding when decryption is necessary.

What could go wrong there?

Government, at all levels, is responsible

During the hearing, TNA reported, technology experts warned the panel that giving the FBI limitless access to the personal electronic data of Americans would open it up to exploitation by "bad actors." But Comey was having none of that.

"It is clear that governments across the world, including those of our closest allies, recognize the serious public safety risks if criminals can plan and undertake illegal acts without fear of detection," he told the committee.

"Are we comfortable with technical design decisions that result in barriers to obtaining evidence of a crime?"
So, in essence, Comey  like many before him, especially since the global war on terror was launched – believes that, in the name of national security Americans ought to give up more of their individual and constitutional rights because that's the only way we can be adequately protected.

Perhaps realizing that his Senate hearing testimony was public, Comey gave the Constitution a passing glance, noting that the government should respect the "requirements and safeguards of the laws" and the country's founding document. However, as Americans now know, spy agencies during the past two presidential administrations have been tasked increasingly with conducting warrantless, unchecked surveillance of Americans' electronic data and communications.

But all of this is not on men like Comey and Presidents George W. Bush and Barack Obama. Congress bears its share of responsibility, too.""

Exotic States of Matter Reveal Plasma Secrets Through Particle Jets at Cern

""When the LHC accelerator at the world's largest laboratory in CERN, Geneva, collided two lead ions travelling at nearly the speed of light, for a fraction of a second ordinary matter was transformed into the most exotic state of matter known to physics: quark-gluon plasma. Analysis of the streams of particles penetrating the plasma has led to new findings about the properties of the plasma, and was recently published in the journal Physical Review Letters by the international team of physicists working at the ATLAS detector.
Immediately following the Big Bang and the formation of space-time, the Universe was filled with matter of extraordinary properties. Quarks and gluons, today only found bound within protons and neutrons, bounced about freely, comprising a homogenous 'soup'. This exceptional state of matter, appearing only at temperatures of billions of degrees, has been recreated by physicists at the LHC accelerator by colliding heavy lead ions.
Study of the quark-gluon plasma poses an enormous challenge. It appears only rarely during collisions, in extremely minute quantities, and then only for a fraction of a second. It immediately begins to expand under its own pressure, rapidly cools and transforms itself into an avalanche of ordinary particles. Modern physics has no tools at its disposal to directly observe quarks and gluons. We cannot simply proceed with the usual methods of measurement, like inserting a thermometer into the plasma and waiting a few minutes for the results. Much more refined methods are needed.
"Fortunately detectors like the ATLAS detector have suceeded in recording the decay products of particles which have interacted in the quark-gluon plasma. By carefully analysing the properties of those particles, we can come to guarded conclusions about the features of the plasma," says Prof. Barbara Wosiek of the Institute of Nuclear Physics of the Polish Academy of Sciences in Kraków, Poland, who coordinated and approved the analysis of data gathered by the ATLAS detector in 2011. The analysis was performed by a team from Columbia University.
Most of the information we have on the quark-gluon soup is provided by particles that disperse sideways as the result of a collision. As they move in this specific direction, crosswise to the initial direction of flight of the lead nuclei, it makes it relatively easy to distinguish them from thousands of other particles and assures that they resulted from the early stage of the collision. If so, immediately after the collision they had to traverse through the quark-gluon cloud, to then collapse into a concentrated narrow stream of particles, known as jets.
"These initially produced particles lose energy while going through the hot, dense plasma soup, which leads to extinguishing the high-energy jets. Through our analysis we go about reconstructing jets of an extremely high energy level, reaching 400 gigaelectronvolts," adds Prof. Wosiek.
After gathering the data on the reconstructed jets in the collision of lead nuclei, the team of physicists can correlate and compare the results with those obtained from proton-proton collisions. The idea behind such a comparison is quite simple. From a precise enough theoretical consideration it is expected that quark-gluon plasma will not arise in a proton-proton collision. In turn, theoretical models of heavy ions in collision predict the formation of dense plasma in a head-on ion-ion collision of extremely high energy. Comparison of results from the data analysis of both types of collisions enables evaluation of how the jets are disturbed by the presence of plasma.""

Photonic Booms Faster-Than-Light Could Unlock Astronomical Secrets


""If you sweep a laser pointer across the Moon fast enough, you can create spots that actually move faster than light. Anyone can do it.

This image depicts Hubble's Variable Nebula.

At a meeting of the American Astronomical Society in Seattle, Wash., today, Robert Nemiroff, a physics professor at Michigan Technological University, reported that this theoretical curiosity may turn out to be practically useful out in the cosmos. When a superluminal sweep occurs, it typically starts with a flash that may reveal previously unknown three-dimensional information about the scattering object.
Flashes, dubbed "photonic booms" because they are directly analogous to sonic booms, may be detectable on the Moon, on passing asteroids, on fast moving shadows cast on reflecting dust clouds near variable stars, and on objects illuminated by the rapidly rotating beam of a pulsar, said Nemiroff, author of a study accepted for publication by the Publications of the Astronomical Society of Australia, with a preliminary version available online at http://arxiv.org/abs/1412.7581. "And if detected, we could learn more about all of these objects," said Nemiroff.

To reveal the size and surface features of asteroids passing near the Earth, a laser beam might be swept across the rock's surface thousands of times a second, with each sweep forcing a harmless but telling photonic boom. The flashes could be recorded with high-speed cameras attached to large telescopes, potentially mapping out major features on the asteroid.
"The concept, although not proven in practice, is quite intriguing," said Rosanne Di Stefano, a leading researcher at the Harvard-Smithsonian Center for Astrophysics.
Photonic booms could also be seen much farther out in the universe. An example occurs in Hubble's Variable Nebula in the constellation of Monoceros. There, shadows cast by clouds moving between the bright star "R Mon" and reflecting dust move so fast that they might create photonics booms visible even for days or weeks.
The physics that creates the photonic boom is tied to the faster-than-light sweep speeds of the illuminating spots and cast shadows. Specifically, a flash is seen by an observer when the speed of the scattered spot toward the observer drops from above the speed of light to below the speed of light. The phenomenon is possible only because the spots contain no mass and so cannot only move faster than light, but decelerate past the speed of light without violating Einstein's theory of special relativity""
