  • The Physics of why the e-Cat's Cold Fusion Claims Collapse

    12/06/2011 6:22:41 AM PST · by Johnny B. · 98 replies · 1+ views
    "Starts with A Bang!" Blog ^ | 12/5/2011 | Dr. Ethan Siegel, Dr. Peter Thieberger
    This claim is made for two reasons: There is anomalous heat/energy being generated by the device, as evidenced by water that has been heated and/or boiled by the e-Cat. This heat is measured by outside observers and cannot be accounted for, completely, by the external power input. A sample of the claimed products of the reaction was made available, which contained some nickel powder, but about 10% of the sample was copper, claimed to be completely generated from an initial sample that was 100% nickel. Right here, this very site claimed that these results were probably faked, and now we're...

    A metallic lattice of hair-thin pipes is now the lightest solid yet created — less dense than air, scientists revealed. The strategy used to create these intricate structures could lead to revolutionary materials of extraordinary strength and lightness, including ones made of diamond, researchers added. Ultra-lightweight materials such as foams are widely used in thermal insulation and to dampen sounds, vibrations and shocks.

    Explanation: What's large and blue and can wrap itself around an entire galaxy? A gravitational lens mirage. Pictured above, the gravity of a luminous red galaxy (LRG) has gravitationally distorted the light from a much more distant blue galaxy. More typically, such light bending results in two discernible images of the distant galaxy, but here the lens alignment is so precise that the background galaxy is distorted into a horseshoe -- a nearly complete ring. Since such a lensing effect was generally predicted in some detail by Albert Einstein over 70 years ago, rings like this are now known as...

    Carnegie Institution ^ | December 19, 2011
    Washington, D.C. -- The crushing pressures and intense temperatures in Earth's deep interior squeeze atoms and electrons so closely together that they interact very differently. With depth materials change. New experiments and supercomputer computations discovered that iron oxide undergoes a new kind of transition under deep Earth conditions. Iron oxide, FeO, is a component of the second most abundant mineral at Earth's lower mantle, ferropericlase. The finding, published in an upcoming issue of Physical Review Letters, could alter our understanding of deep Earth dynamics and the behavior of the protective magnetic field, which shields our planet from harmful cosmic rays....

    Explanation: Why do objects have mass? To help find out, Europe's CERN has built the Large Hadron Collider (LHC), the most powerful particle accelerator yet created by humans. Since 2008, the LHC smashed protons into each other with unprecedented impact speeds. The LHC is exploring the leading explanation that mass arises from ordinary particles slogging through an otherwise invisible but pervasive field of virtual Higgs particles. Were high energy colliding particles to create real Higgs bosons, the Higgs mechanism for mass creation will be bolstered. Last week, two LHC groups reported on preliminary indications that the Higgs boson might exist...

    ...The properties and mass of the LHC's Higgs boson suggest that physicists will soon find superpartners for particles, and that we have begun to connect string theory to the real world... Physicists thought that a Higgs boson, when discovered, would take this supersymmetric form, so how have we discovered one so apparently identical to the impossible standard-model version? Working out how to interpret this could be a large step towards the underlying broader theory that will extend the standard model. One explanation could come from an unexpected source: string theory or its extension, M-theory. Contrary to what you may have...

    Last Friday, I realized the sort of place I work in: an academic Computer Science institute that bears more than a passing resemblence to the ficticious TV town of 'Eureka'. We don't have flying cars, or intelligent, rebellious, precocious attack bots, but we do have some cool stuff. Take the 128-QuBit Quantum Computer housed the ground floor of parking lot where a sandwich shop used to be, for example. This is the next generation of computers, using the superposition effects of quantum mechanics to process vastly many more states than our current 'classical' computers can accomplish. This is the sort...

    The Higgs boson is a theoretical particle which scientists believe gives mass to everything in the universe, and is a key component of the Standard Model of physics. While finding it in its expected form would confirm common theories on how atoms are put together, identifying a number of Higgs bosons with different masses or disproving the particle entirely would overturn many assumptions of modern physics.
  • Two Diamonds Linked by Strange Quantum Entanglement

    LiveScience ^ | Thursday, December 1, 2011 | Clara Moskowitz
    Scientists have linked two diamonds in a mysterious process called entanglement that is normally only seen on the quantum scale. Entanglement is so weird that Einstein dubbed it "spooky action at a distance." It's a strange effect where one object gets connected to another so that even if they are separated by large distances, an action performed on one will affect the other. Entanglement usually occurs with subatomic particles, and was predicted by the theory of quantum mechanics, which governs the realm of the very small...

    Utah chemists: Water doesn't have to freeze until minus 55 FahrenheitSALT LAKE CITY -- We drink water, bathe in it and we are made mostly of water, yet the common substance poses major mysteries. Now, University of Utah chemists may have solved one enigma by showing how cold water can get before it absolutely must freeze: 55 degrees below zero Fahrenheit. That's 87 degrees Fahrenheit colder than what most people consider the freezing point of water, namely, 32 F. Supercooled liquid water must become ice at minus 55 F not just because of the extreme cold, but because the molecular...

    Princeton University ^ | November 22, 2011 | Steven Schultz
    Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap over a small hole in a metal film does not stop the light at all, but rather enhances its transmission. In an example of the extraordinary twists of physics that can occur at very small scales, electrical engineer Stephen Chou and colleagues made an array of tiny holes in a thin metal film, then blocked each hole with an opaque metal cap. When they...

    New high-precision tests carried out by the OPERA collaboration in Italy broadly confirm its claim, made in September, to have detected neutrinos travelling at faster than the speed of light. The collaboration today submitted its results to a journal, but some members continue to insist that further checks are needed before the result can be considered sound. OPERA (Oscillation Project with Emulsion-Tracking Apparatus) measures the properties of neutrinos that are sent through the Earth from the CERN particle physics laboratory in Geneva, Switzerland, and arrive in its detector located under the Gran Sasso mountain in central Italy. On 22 September,...

    The world's largest atom smasher, designed as a portal to a new view of physics, has produced its first peek at the unexpected: bits of matter that don't mirror the behavior of their antimatter counterparts. The discovery, if confirmed, could rewrite the known laws of particle physics and help explain why our universe is made mostly of matter and not antimatter. Scientists at the Large Hadron Collider, the 17-mile (27 km) circular particle accelerator underground near Geneva, Switzerland, have been colliding protons at high speeds to create explosions of energy. From this energy many subatomic particles are produced. Now researchers...

    A second experiment at the European facility that reported subatomic particles zooming faster than the speed of light -- stunning the world of physics -- has reached the same result, scientists said late Thursday. The "positive outcome of the [second] test makes us more confident in the result," said Fernando Ferroni, president of the Italian Institute for Nuclear Physics, in a statement released late Thursday. Ferroni is one of 160 physicists involved in the international collaboration known as OPERA (Oscillation Project with Emulsion Tracking Apparatus) that performed the experiment. While the second experiment "has made an important test of consistency...

    Nature ^ | 17 November 2011 | Eugenie Samuel Reich
    At the heart of the weirdness for which the field of quantum mechanics is famous is the wavefunction, a powerful but mysterious entity that is used to determine the probabilities that quantum particles will have certain properties. Now, a preprint posted online on 14 November1 reopens the question of what the wavefunction represents — with an answer that could rock quantum theory to its core. Whereas many physicists have generally interpreted the wavefunction as a statistical tool that reflects our ignorance of the particles being measured, the authors of the latest paper argue that, instead, it is physically real. “I...

    PRESS RELEASE: Scientists at Chalmers have succeeded in creating light from vacuum – observing an effect first predicted over 40 years ago. The results have been published in the journal Nature. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum. The experiment is based on one of the most counterintuitive, yet, one of the most important principles in quantum mechanics: that vacuum is by no means empty nothingness. In fact, the vacuum is full of various particles that are continuously fluctuating in and out of existence....
