Accidental Discovery Dramatically Improves Electrical Conductivity - - iTech Post - 3 views

  •  
    Oh those bloody physicists... someone forgot to turn off the lights and now they have a 400 times better conductive crystal. If science was always that easy, I would light a candle every day.

    One of the reason why I like science, those random things that sometimes happen with outcomes you just didn't expect
  •  
    Apparently this was not the first discovery of this effect involving SrTiO3. In an article from 2012 a conductance increase of 5 orders in magnitude is described (http://pubs.acs.org/doi/abs/10.1021/nn203991q). But indeed many large impact discoveries are accidental...

    I thought we all knew already that science is just another form of directed random search :)))

William Shatner Wakes Up Crew for Final Discovery Mission - Slashdot - 1 views

  • The Space Shuttle Discovery left the International Space Station this morning for the last time. To commemorate the ship's accomplishments over 27 years of service, the crew was greeted to a morning wake-up message from Capt. Kirk. "Space, the final frontier," Shatner said in a prerecorded message. "These have been the voyages of the space shuttle Discovery. Her 30-year mission: to seek out new science, to build new outposts, to bring nations together on the final frontier, to boldly go and do what no spacecraft has done before."
  •  
    here's a recording of the transmission: http://ia600406.us.archive.org/13/items/STS-133/03-07-11_STS-133_FD12_Crew_Wakeup.mp3 to quote from the thread at reddit: "When the space shuttle first flew, 55 americans were being held hostage in the embassy in Iran, and Ronald Reagan had just become president. That same year Prince Charles would marry Lady Diana, the HIV virus would be first identified, Post-It notes were invented, and a small company called Microsoft released it's new operating system MS-DOS."

Attack on the pentagon results in discovery of new mathematical tile - 2 views

  •  
    In the world of mathematical tiling, news doesn't come bigger than this. In the world of bathroom tiling - I bet they're interested too. If you can cover a flat surface using only identical copies of the same shape leaving neither gaps nor overlaps, then that shape is said to tile the plane. Also only mathematicians can put the words "Pentagon", "attack", and "plane" in the same sentence...
  •  
    I especially love this part of the story: "The hunt to find and classify the pentagons that can tile the plane has been a century-long mathematical quest, begun by the German mathematician Karl Reinhardt, who in 1918 discovered five types of pentagon that do tile the plane. (To clarify, he did not find five single pentagons. He discovered five classes of pentagon that can each be described by an equation. For the curious, the equations are here. And for further clarification, we are talking about convex pentagons, which are most people's understanding of a pentagon in that every corner sticks out.) Most people assumed Reinhardt had the complete list until half a century later in 1968 when R. B. Kershner found three more. Richard James brought the number of types of pentagonal tile up to nine in 1975. That same year an unlikely mathematical pioneer entered the fray: Marjorie Rice, a San Diego housewife in her 50s, who had read about James' discovery in Scientific American. An amateur mathematician, Rice developed her own notation and method and over the next few years discovered another four types of pentagon that tile the plane. In 1985 Rolf Stein found a fourteenth. Way to go!"

[1101.6015] Radio beam vorticity and orbital angular momentum - 1 views

  • It has been known for a century that electromagnetic fields can transport not only energy and linear momentum but also angular momentum. However, it was not until twenty years ago, with the discovery in laser optics of experimental techniques for the generation, detection and manipulation of photons in well-defined, pure orbital angular momentum (OAM) states, that twisted light and its pertinent optical vorticity and phase singularities began to come into widespread use in science and technology. We have now shown experimentally how OAM and vorticity can be readily imparted onto radio beams. Our results extend those of earlier experiments on angular momentum and vorticity in radio in that we used a single antenna and reflector to directly generate twisted radio beams and verified that their topological properties agree with theoretical predictions. This opens the possibility to work with photon OAM at frequencies low enough to allow the use of antennas and digital signal processing, thus enabling software controlled experimentation also with first-order quantities, and not only second (and higher) order quantities as in optics-type experiments. Since the OAM state space is infinite, our findings provide new tools for achieving high efficiency in radio communications and radar technology.

Helix Nebula - Helix Nebula Vision - 0 views

  •  
    The partnership brings together leading IT providers and three of Europe's leading research centres, CERN, EMBL and ESA in order to provide computing capacity and services that elastically meet big science's growing demand for computing power.

    Helix Nebula provides an unprecedented opportunity for the global cloud services industry to work closely on the Large Hadron Collider through the large-scale, international ATLAS experiment, as well as with the molecular biology and earth observation. The three flagship use cases will be used to validate the approach and to enable a cost-benefit analysis. Helix Nebula will lead these communities through a two year pilot-phase, during which procurement processes and governance issues for the public/private partnership will be addressed.

    This game-changing strategy will boost scientific innovation and bring new discoveries through novel services and products. At the same time, Helix Nebula will ensure valuable scientific data is protected by a secure data layer that is interoperable across all member states. In addition, the pan-European partnership fits in with the Digital Agenda of the European Commission and its strategy for cloud computing on the continent. It will ensure that services comply with Europe's stringent privacy and security regulations and satisfy the many requirements of policy makers, standards bodies, scientific and research communities, industrial suppliers and SMEs.

    Initially based on the needs of European big-science, Helix Nebula ultimately paves the way for a Cloud Computing platform that offers a unique resource to governments, businesses and citizens.

    Reminds me of this - the discovery of the LGM-1 (LGM= Little Green Men indeed): http://www.aps.org/publications/apsnews/200602/history.cfm It turned out to be the first discovery of a pulsar, re-compensated by a Nobel Prize in Physics

    Guys in SETI have come out with a precision setup to analyze if we have found the true Death Star: http://phys.org/news/2015-12-extraterrestrial-laser-pulses-kic-seti.html Conclusions are no laser light coming out from there..
  •  
    to be honest, while the alien megastructure is a cookie idea, I highly doubt that those aliens woke up one day and thought: "hm, let's send laser pulses at this particular random spot in space sometime in the next 6 days".

    some ideas for movie Fridays A "must" see on my opinion (never heard about it in the past!) : Primer Sounds ideal: "Primer is a 2004 American science fiction film about the accidental discovery of time travel. The film was written, directed and produced by Shane Carruth, a mathematician and a former engineer, and was completed on a budget of $7,000.[1] Primer is of note for its extremely low budget, experimental plot structure and complex technical dialogue, which Carruth chose not to 'dumb down' for the sake of his audience. One reviewer said that "anybody who claims [to] fully understand what's going on in Primer after seeing it just once is either a savant or a liar."[2] The film collected the Grand Jury Prize at Sundance in 2004 before securing a limited release in US cinemas, and has since gained a cult following."
  •  
    I watched it a while ago during my studies in Belgium... The plot is quite well summarized on this diagram: http://xkcd.com/657/large/ According to the text above I'm either savant or a liar (you choose). But I watched the movie under significant exposure to Belgian beer, so this may have helped...
