Author(s): Gerardo A. Paz-Silva, A. T. Rezakhani, Jason M. Dominy, and D. A. Lidar
It is well known that the quantum Zeno effect can protect specific quantum states from decoherence by using projective measurements. Here we combine the theory of weak measurements with stabilizer quantum error correction and detection codes. We derive rigorous performance bounds which demonstrate t...

Bad wiring could be behind superluminal neutrino result

Posted: February 22nd, 2012, 4:01pm MST by Physics Today

Science: A bad connection between a GPS unit and a computer could be behind the OPERA collaboration's determination last year that neutrinos travel faster than light. Sources familiar with the experiment told Science's Edwin Cartlidge that they had discovered a loose connection between a computer and a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' journey. The original timing discrepancy was 60 nanoseconds. After tightening the connection, the researchers found that data arrive 60 ns earlier than they had previously assumed, thereby nullifying the discrepancy and removing the need to invoke superluminal travel.
Nuclear power entrepreneurs advocate using thorium as a fuel

Posted: February 22nd, 2012, 3:40pm MST by Physics Today

Washington Post: Thorium, which exists in the ground as thorium oxide and is three to four times more plentiful worldwide as uranium, is getting another look as a potential nuclear fuel. It was used at an Oak Ridge Laboratory reactor from 1965 to 1969, but that program fell by the wayside when fears of proliferation cast a pall over experimental nuclear programs in the US. Advocates of thorium technology want to see existing plants, which use uranium, adapted to use thorium—or replaced, once they reach obsolescence, with liquid-fluoride thorium reactors (LTFR). LTFRs use molten chemical salts to cool the reactor and transfer energy from the fission reaction to a turbine. Because LTFRs aren't pressurized and don't use water for cooling, the risk of hydrogen explosions is eliminated. The nuclear industry is somewhat skeptical for the most part.

Posted: February 22nd, 2012, 1:44pm MST by Physics Today

Nature: Many species of squid can propel themselves through the air by squirting water out of their mantles, just as they do to swim. Flying is not only faster for squid than swimming is; it may also save them energy over long distances. Ronald O’Dor of Dalhousie University in Halifax, Canada and Julia Stewart of Stanford University in California studied a set of photos of orange-back squid (Sthenoteuthis pteropus) leaping out of the water and calculated their speed and acceleration. The squids' speed in air while the squid were propelling themselves with the water jet was five times faster than than any measurements O’Dor had made for comparable squid species in water. O'Dor believes that squid use flight as a way to save energy, but it could be the case that the squid use flight to avoid predators. To find out, O'Dor proposes to estimate what proportion of time squid spend above water by fitting them with tags that measure acceleration, and then investigating the gliding, rather than just the rocketing, part of their flight.
Hubble scientists detect new type of planet

Posted: February 22nd, 2012, 10:12am MST by Physics Today

MSNBC: Observations by NASA's Hubble Space Telescope have confirmed a so-called super-Earth a mere 40 light-years away. GJ 1214b is about 2.7 times Earth's diameter and weighs nearly seven times as much. Most notable, however, is the fact that a huge fraction of its mass is made up of water. Because of its high temperatures and high pressures, GJ 1214b likely has a steamy atmosphere and an interior structure made up of exotic materials alien to Earth, such as hot ice or superfluid water, according to Zachory Berta of the Harvard–Smithsonian Center for Astrophysics in Cambridge, Massachusetts, who is one of the authors of a paper published online in the Astrophysical Journal. Scientists hope that NASA's James Webb Space Telescope may be able to get a better look once it is launched in 2018.
Climate document leak leads to scientist's resignation

Posted: February 22nd, 2012, 8:36am MST by Physics Today

Los Angeles Times: Peter Gleick, a noted scientist and environmentalist, has admitted to obtaining documents under false pretenses from the Heartland Institute, a libertarian group that questions climate change. The documents were leaked to the press last week. In a statement he posted on Monday on the Huffington Post, Gleick says that in early 2012 he received an anonymous document in the mail that seemed to describe the institute's climate program strategy. He then "solicited and received additional materials directly from the Heartland Institute under someone else's name." Yesterday the American Geophysical Union announced Gleick's resignation as chair of its task force on scientific ethics and criticized his deception regarding the institute. "Gleick's admission is sure to further intensify an already bitter debate between those who accept the scientific consensus on climate change and those who doubt it," writes Neela Banerjee for the Los Angeles Times.
Plants grown from Late Pleistocene-age fruit

Posted: February 21st, 2012, 12:32pm MST by Physics Today

New York Times: Russian scientists claim to have grown plants from the fruit of a campion flower that died 32 000 years ago. Svetlana Yashina and David Gilichinsky, of the Russian Academy of Sciences research center at Pushchino, near Moscow, and colleagues published their findings today in the Proceedings of the National Academy of Sciences. The fruit had been excavated several years ago from an arctic ground squirrel's burrow in northeastern Siberia. To grow the plants, the scientists used cells from the fruit’s placenta after failing to germinate the seeds. They obtained the radiocarbon date from the seeds, however. If the group's claim is true, it would enable scientists to study evolution in real time by comparing the ancient and living campions, writes Nicholas Wade for the New York Times.
EU to vote on Canadian oil sands pollution

Posted: February 21st, 2012, 10:43am MST by Physics Today

BBC: The European Union is scheduled to vote on 23 February to decide whether Canadian oil extracted from oil sands is more polluting than oil from other parts of the world. The vote comes in the wake of a lawsuit filed by the Beaver Lake Cree native people, who claim that the oil sands industry is damaging the environment—fish and game have developed cancers, water has been polluted, and hunting grounds have been deforested—and thus endangering their traditional way of life, which is guaranteed by a treaty with the provincial and federal governments of Canada. Drew Zieglgansberger, senior vice president of Cenovus Energy, one of the oil companies involved, says that the industry has invested hundreds of millions of dollars to improve oil extraction techniques and provided jobs for many indigenous people.

El diario Marca y la física cuántica

Posted: February 22nd, 2012, 8:17am MST by Daniel Manzano

Como ya hemos hablado en anteriores ocasiones la física cuántica se está convirtiendo en la excusa predilecta de charlatanes, vendehumos y magufos. Ejemplos son la medicina cuántica, el intento de estafa de cronoaltera, la powerbalance o la homeopatía. Otro ejemplo muy de moda ahora es el origen de la conciencia y las filosofías milenarias, como ejemplo fue el pseudocongreso "Ciencia y conciencia", que intentó censurar este post.
A pesar de todo esto siempre queda sitio para la sorpresa. Hoy en Twitter he visto que incluso un periódico deportivo, Marca, ha decidido sumarse a la moda de usar la física cuántica para vender humo. De paso han decidido pasarse por el forro todo el rigor científico y el sentido común, con lo que queda todo mucho más interesante.
El artículo, titulado Cómo mejorar el rendimiento en el deporte a través de la conciencia, comienza diciendo "Los descubrimientos que la ciencia –en especial la física cuántica- ha hecho en los últimos tiempos han constatado que, en contra de lo que se creía tradicionalmente, especialmente en el mundo occidental, ya no habitamos más en un universo material, externo, objetivo e inerte, sino que muy al contrario éste forma parte de un campo de energía que lo conecta todo, de naturaleza holográfica, donde lo que hacemos en una parte afecta en mayor o menor medida a la totalidad y de manera instantánea."
Es difícil hacer una frase más larga, incomprensible y a la vez llena de falacias. Queda muy bien eso de incluir algo como "de naturaleza holográfica" sin explicar que significa, da sensación de ser algo importante. Es mejor que no se entienda, porque así es difícil que la gente critique. Es un claro ejemplo de antidivulgación, en vez de intentar hacer las cosas comprensibles a la gente, se hacen deliberadamente no comprensibles para aparentar sofisticación.
El tema realmente científico que el autor intenta aprovechar para vendernos su artículo de autoayuda es lo que en física conocemos como el Principio Holográfico. Este, explicado de manera sencilla, se basa en el hecho de que la entropía de un agujero negro depende de su área y no de su volumen. Como la entropía se puede interpretar como una medida de la información del agujero negro esto indica que toda la información del mismo está en su superficie. De ahí alguna gente deduce que la información del universo (que viene a ser como un agujero negro inmenso) se puede condensar sólo en su superficie, y que el interior que nosotros vemos es sólo una consecuencia. Interesante ¿verdad? En mi opinión sí y mucho, pero a día de hoy no deja de ser algo especulativo. Forma parte de la gravedad cuántica, que es una teoría aún en desarrollo. No es, repito NO ES, algo que diga la física cuántica. Para más información se puede ver este post.
El texto continúa con: "entiendo que lo que te voy a contar te pueda resultar difícil de creer porque suena un poco fantástico, pero debes saber que todo está respaldado por abundantes experimentos científicos y testimonios que puedes encontrar en la bibliografía. Para poder comprenderlo y aceptarlo como verdadero necesariamente tendrás que abrir mucho la mente y revisar tus creencias más profundas…"

Evidentemente "la bibliografía" no se incluye en el artículo. Viene a decir, que si no te lo crees, que busques en todos los libros del mundo que alguno le dará la razón. En cuanto a lo de los experimentos sólo menciona uno luego, da la casualidad de ser uno falso.

"Asumo también que salvo que hayas vivido estados alterados (expandidos) de conciencia –con cualquiera de los métodos que las facilitan- no podrás conseguirlo (más adelante entenderás por qué)"

No se a que se refiere con "estados alterados (expandidos) de conciencia", pero si os aviso de que para tragaos todo lo que viene hacen falta estados expandidos de los buenos, que vengan de Amsterdam al menos.

La mayor parte del texto habla de deporte, chakras, ego y demás. Ahí no me meto porque no es mi campo. Sigo hasta la parte en la que vuelve a la carga con el universo holográfico y la física: "Tal vez en este punto te estés preguntando que si todo es energía ¿por qué lo que llamamos realidad es material? La respuesta es sencilla aunque bastante sorprendente, me temo: porque no lo es. Lo que sucede es que tus sentidos decodifican determinados rangos de frecuencias de energía que mandan a tu cerebro, que los interpreta como algo sólido."

Aquí partimos de un supuesto incorrecto, que todo es energía. Según la relatividad especial (y no la cuántica) la energía y la masa se pueden transformar una en la otra siguiendo la famosa ecuación $E=mc^2$. ¿Quiere decir esto que son lo mismo la masa y la energía? Bueno, eso es una cuestión de interpretación. Si el agua se puede convertir en hielo y el hielo en agua ¿son la misma cosa? Yo diría que no, porque tienen propiedades diferentes (yo no me enfrío los cubatas con agua habitualmente), pero en cualquier caso es una cuestión semántica. Lo que es cierto es que si decidimos que son la misma cosa tan correcto es decir que el universo está compuesto sólo por energía, como decir que está compuesto sólo por masa. Si son lo mismo son lo mismo. Ambas, la masa y la energía son propiedades de la materia, o la misma propiedad si lo preferís, no la materia en si que tiene más propiedades.

Para no aburrir paso ya a la parte donde describe el experimento en cuestión: "El Dr. Emoto llevó a cabo durante años profundas investigaciones sobre el agua, caso especial por tratarse del medio en el que se desarrolla nuestra actividad deportiva, pero las hizo desde una perspectiva mucho más científica de lo que nunca antes se habían hecho: utilizó un MRA (Analizador de Resonancia Magnética) y se dedicó a medir el HADO6 de los cristales formados en el agua analizada, al principio microparticulada y luego simplemente agua común. Tomaba muestras de ríos, embalses, lagos, etc. por todo Japón y de muchos otros lugares del mundo. Fotografiaba sus estructuras moleculares cristalizadas, las metía en frascos de vidrio y a continuación las exponía durante horas a distintos tipos de estímulos, unos..."

Donde aparece, como no, Masaru Emoto. Sobre este individuo ya escribí un post que podéis leer para más información. Os lo resumo por si os da pereza: Los experimentos son falsos, se han repetido siempre con resultados negativos y el mismo Emoto ha reconocido que no pueden ser considerados ciencia. Si alguien los repite con éxito se ganará un millón de euros (y un premio Nobel sin duda).

Hay bastante más en el artículo criticable, pero no me quiero extender. Sólo aconsejar que si leéis algo que mencione a la física cuántica seáis escépticos, pidáis referencias, uséis el sentido común y consultéis a los expertos. Criticar también al diario Marca, que se supone que es un diario serio, de deportes pero serio, por publicar semejantes cosas. Si las noticias puramente deportivas tienen el mismo rigor que estas no os creáis nada de lo que digan.

Beethoven: Violin Concerto, Romances

Posted: February 22nd, 2012, 11:50am MST

Christian Tetzlaff is a brilliant violinist, one whose technique is equaled by his intelligence. He recorded a very respectable Beethoven Violin Concerto with Michael Gielen, last available on Point Classics in so-so sound. This newcomer is finer still, an interpretation with real personality and a point of view. It's a reading of high contrasts in which the music's antithesis between energetic outbursts (particularly in the first movement) and lyrical effusiveness comes to the fore. Zinman establishes this dichotomy right from the beginning: tempos are swift, accents are sharp, and when Tetzlaff enters, the polarity between solo and orchestra swiftly establishes itself.

In this context, Tetzlaff's use of Beethoven's own cadenza from the piano concerto version of the piece, recast for solo violin, proves an inspired choice, carrying the drama straight through to the end of the movement. The Larghetto finds Tetzlaff offering tenderness and real "Innigkeit" without a shred of excessive sentimentality; and as throughout the performance his exchanges with the orchestra's woodwind section are just lovely.
Even in the rambunctious finale Tetzlaff displays remarkable variety in his phrasing of the main theme, at first a touch subdued, as if still shrugging off the previous movement's legato dreaminess, but then frisky and buoyant. It's a remarkably comprehensive conception of the piece, and the two Romances, the logical coupling, seldom have sounded more elegant. Great sonics make this a version that, like Zinman's recording of the Triple Concerto, really will make you listen to the music with fresh ears. --David , ClassicsToday.com

Tchaikovsky: Capriccio italien · Romeo & Juliet Suite · Marche Slave · Ouverture 1812

Posted: February 22nd, 2012, 11:42am MST

"Karajan opens 1812 with the Don Cossack Choir (whom he greatly admired) resonantly replacing the lower strings. Surprisingly they don't return at the end, but the orchestral playing has plenty of zest throughout and a heart-warming lyrical strain from the violins. The coda, with its aural curtain of carillon and the canon shots precisely placed, sounds a little contrived, but is certainly spectacular. Again the transfers are first class" --Gramophone

Bach: Goldberg Variations

Posted: February 21st, 2012, 4:32pm MST

“No mannerisms, no distractions, no self-serving virtuosity - just the most lucid and moving recording yet of this work.” --Gramophone
“uniquely revealing, essentially thoughtful and intimate, often introvert, and with his involvement and dedication present in every bar. The piano recording, too, is wonderfully natural.” --The Penguin Guide 2011

I have no hesitation at all in acclaiming Murray Perahia's recording of the Goldberg Variations as the finest on piano since Glenn Gould's pioneering version of the 1950s. Both in its broad conception and individual details, it offers incontestable evidence of Perahia's penetrating musical intellect, sensitivity to emotional nuance, and exceptional technical gifts. A performance this rich and varied in expression deserves to be considered at much greater length than that of a simple record review, but perhaps a few general observations will suffice to indicate what an extraordinary listening experience this release represents.
