How the tail wags the dog in ultracold atomic gases

The development of the field of ultracold atoms has opened up new frontiers in both few-body and many-body physics. Of particular interest are universal aspects that apply equally well not only to various species of atoms, but also to other types of particles with short-range interactions. In the current issue of Physical Review A, Shizhong Zhang and Anthony Leggett of the University of Illinois report their derivations of some remarkable properties of ultracold atomic gases that exploit interesting connections between few-body and many-body physics [1].

Hace 200 años nació Mendelssohn, el Mozart del siglo XIX

Como se sabe, muchos grandes artistas sólo alcanzaron la fama después de su muerte. Sin embargo, con el Mozart del siglo XIX , como lo llamó su colega compositor Robert Schumann, pasó exactamente lo contrario: la fama de Felix Mendelssohn Bartholdy, nacido el 3 de febrero de 1809 en Hamburgo, se apagó rápidamente después de su temprana muerte. Hoy, sin embargo, Mendelssohn Bartholdy es otra vez un compositor muy apreciado en su natal Alemania. Varias obras del músico romántico, prohibido por los nazis, que habían permanecido inéditas o ignoradas son interpretadas por primera vez, entre ellas la ópera Der Onkel aus Boston (El tío de Boston), más de 180 años después de su conclusión. Y el 200 aniversario del nacimiento de Mendelssohn Bartholdy es motivo de celebraciones, si bien no en la misma medida que el 250 natalicio de Mozart en el superaño musical 2006.

Hallaron restos de histórico barco "HMS Victory" en Canal de La Mancha

La empresa estadounidense Odyssey descubrió los restos del "HMS Victory", el barco almirante británico que se hundió en 1744 y cuyo homónimo sucesor hizo vencer al almirante Nelson frente a las fuerzas franco-españolas en Trafalgar, según la prensa británica dominical. "Los submarinistas piensa que hallaron los restos de uno de los más prestigiosos veleros británicos de todos los tiempos", escribe el Sunday Times, precisando que Odyssey tiene intención de anunciar el descubrimiento el lunes.

Essay: Fifty Years of Condensed Matter Physics

Marvin L. Cohen

Since the birth of Physical Review Letters fifty years ago, condensed matter physics has seen considerable growth, and both the journal and the field have flourished during this period. In this essay, I begin with some general comments about condensed matter physics and then give some personal views on the conceptual development of the field and list some highlights. The focus is mostly on theoretical developments.

Millions hit by Google 'breakdown'

An apparent system error left millions of visitors to the site puzzled when links to all search results were flagged with the warning 'This site may harm your computer'. It is thought the site had erroneously identified all other websites - and some of its own pages - as containing malicious software or 'malware'.

One Twitterer, BradBrownDotCom, joked: "The Google outage frightened me like a schoolgirl, until I remembered an old technology called 'Yahoo'".

Irak Love

I just yelled to say 'I love you'

Dozens of tongue-tied Japanese men met in a Tokyo park to shout messages of love to their wives. In a country where modesty and reticence are traditionally valued over outspokenness, expressing passion can be difficult. Every year like-minded men gather in Hibiya Park in central Tokyo to yell their affection.

Why Don’t Japanese Men Kiss Their Wives?

A dismal 0.56 daily kisses caused the show to state that it was an example of “Bad Nippon.”

Rocío Marquez

Rocío es Andalucía por los cuatro puntos cardinales. Cuando cierra sus preciosos ojos se produce una conexión con el duende que nos hace presenciar su gran ángel llenando de hermosura y frescor el espacio que domina mientras el espectador disfruta embelesado escuchando como La Estrella del Sur traza arabescos vocales y giros fantásticos que son pura orfebrería.

Rocío Márquez Limón, nació en Huelva el 29 de septiembre de 1985. Desde pequeña ya cantaba, pero es a la edad de 9 años cuando comienza a recibir clases de fandangos en la Peña Flamenca de Huelva. En este mismo año, gana el segundo premio de fandangos de Huelva, algo que le motiva para continuar aprendiendo. Paralelamente comienza sus estudios en el conservatorio, cursando hasta cuarto de grado Elemental...

She is the proud winner of different awards for her flamenco interpretations. Last year she won the Fosforito award in Calasparra and this year she received the Ciudad de Jumilla award...See Video

Fundación Thomas Merle

Organización No Gubernamental con sede en la ciudad de Carúpano, creada el 11 de octubre de 1993, un año después de la trágica desaparición física de Thomas Merle.

La Casa del Cable (Wire House)

Una de las cosas que llaman la atención de esta ciudad, es la casa del cable, donde llegó el primer cable submarino entre Europa y América, uniendo la ciudad francesa de Marsella con Carúpano, a finales del siglo XIX. Esta casa, hoy en día, sirve de sede a la Fundación Tomás Merle y del Proyecto Paria, dos de las obras más bellas que se realizan en el país y que han sido premiadas en el extranjero, por representar un modelo de crecimiento armónico entre el turismo, la industria, la naturaleza y la gente.

Quantum dreamin and optical illusions

Quantum consciousness, a phrase that sends most eggheads running for the hills, is currently on a roll. A coupla months back, Efstratios “Moussaka” Manousakis of Florida State University in Tallahassee published a paper suggesting that a certain kinda optical illusion could be explained in quantum terms.

“Is Google Making Us Stupid?” (Britannica Forum: Your Brain Online)

In his cover article in the July/August issue of the The Atlantic Monthly (”Is Google Making Us Stupid?“), Nicholas Carr raises what for some will be an alarming prospect: that we may soon face the end of reading, the end of thinking, and the end of culture as we have known them for hundreds of years, thanks to the Internet and the dramatic ways in which it is reshaping the way we learn, interact, and express ourselves.

Nicholas Carr: All Hail the Information Triumvirate! (The Web, Google, and Wikipedia)

I was reading an interview today with Jorge Cauz, the president of Encyclopedia Britannica, in which he describes some of the Web 2.0-y tools that the company is preparing to roll out to enable readers to contribute to the encyclopedia’s content. (I’m on Britannica’s board of editorial advisors.) The interview touches, as you’d expect, on the great success that Wikipedia has achieved on the Web and, in particular, on its ever increasing dominance of Google search results. Cauz calls the tie between Wikipedia and Google “the most symbiotic relationship happening out there” - and I think he’s right.

Napping: the expert's guide

For years, napping ("siesta") has been derided as a sign of laziness. We are "caught" napping or "found asleep at the switch". But lately it has garnered new respect, thanks to scientific evidence that midday dozing benefits both mental acuity and overall health. A slew of recent studies have shown that naps boost alertness, creativity, mood, and productivity in the later hours of the day.Read more...

How a Surfer Dude Stunned the World of Science With the 'Theory of Everything'

A. Garrett Lisi

A laid-back surfer has just drawn up a new theory of the universe that is blowing the establishment’s socks off. His theory is seen by some as the “Holy Grail of physics”, and is earning rave reviews from distinguished scientists. In fact, his model appears to be the elusive overarching explanation to unite all the particles and forces of the cosmos, which has been the most baffling riddle of modern physics—stumping even Einstein.
