Have We Been Interpreting Quantum Mechanics Wrong This Whole Time? - 6 views

  •  
    "The experiments involve an oil droplet that bounces along the surface of a liquid. The droplet gently sloshes the liquid with every bounce. At the same time, ripples from past bounces affect its course. The droplet's interaction with its own ripples, which form what's known as a pilot wave, causes it to exhibit behaviors previously thought to be peculiar to elementary particles - including behaviors seen as evidence that these particles are spread through space like waves, without any specific location, until they are measured."

    Pilot-wave theory reresurrected. Maybe something for the next "fundamental" :P physics RF?

    And for the next 'Experimental Physics Stagiaire' position why not try to do "Unpredictable Tunneling of a Classical Wave-Particle Association" http://stilton.tnw.utwente.nl/people/eddi/Papers/PhysRevLett_TUNNEL.pdf, there are some rumors online that the results of Yves Couder Experiments can be reproduced with simple DIY vibrating tables!

    It is very funny to see the videos of the MIT's replication of this experiment (with lightening legends for those who are uncomfortable with the concepts involved https://www.youtube.com/watch?v=YF5iHQMjcsM)

    I'm sure Leo will love it. Yet another argument not to have a facebook account or a smartphone.

    absolutely ... so you ditched yours also already?
  •  
    Ditched? I never had either!

    But then on the other hand a recent Dilbert summarised me pretty well...
  •  
    so you also don't have a mobile phone? I thought I knew only one person of my age who does not have one yet ... congratulations

Brain's reaction to virtual reality should prompt further study, suggests new research - 2 views

  •  
    "Neuroscience UCLA neurophysicists have found that space-mapping neurons in the brain react differently to virtual reality than they do to real-world environments. Their findings could be significant for people who use virtual reality for gaming, military, commercial, scientific or other purposes."

    I wonder if we are doing it wrong with the airplane pilot simulators...

Black-hole mergers cast kaleidoscope of shadows - 6 views

  •  
    In Interstellar, the science-fiction film out this week, Matthew McConaughey stars as an astronaut contending with a supermassive black hole called Gargantua. The film's special effects have been hailed as the most realistic depiction ever made of this type of cosmic object. But astrophysicists have now gone one better - this is a really cool visualisation done by researchers in Cornell.
  •  
    Wow, impressive! Simulating eXtreme Spacetimes (SXS) software, very quick merging process though 17ms.. Observable?
  •  
    Mind-blowing!

Science's Favorite Deep-Sea Explorer Gets High-Tech Upgrades | WIRED - 2 views

  •  
    Alvin, the only deep-diving manned submersible used for science has been upgraded, allowing scientists to explore for the 1st time the depth of the oceans down to 6500m bsl.

Programmable biological circuits - 3 views

  •  
    Several new components for biological circuits have been developed by researchers. These components are key building blocks for constructing precisely functioning and programmable bio-computers. "The ability to combine biological components at will in a modular, plug-and-play fashion means that we now approach the stage when the concept of programming as we know it from software engineering can be applied to biological computers.

How Building a Black Hole for Interstellar Led to an Amazing Scientific Discovery | WIRED - 2 views

  •  
    Kip Thorne looks into the black hole he helped create and thinks, "Why, of course. That's what it would do." This particular black hole is a simulation of unprecedented accuracy. It appears to spin at nearly the speed of light, dragging bits of the universe along with it.

Graphene drum could store quantum information - 4 views

  •  
    Devices made from resonating graphene "drums" could be used as microwave amplifiers and memory chips in quantum computers. So say researchers at the Kavli Institute of Nanoscience at the Delft University of Technology in the Netherlands, who are the first to demonstrate optomechanical coupling between a mechanical resonator and a superconducting microwave cavity.

Superabsorbing rings could lead to better cameras and solar cells - 2 views

  •  
    Rings of excited atoms that harness a quantum effect to absorb light at an enhanced rate could be used in future technologies such as highly sensitive cameras, solar cells and systems for optical power transmission.

Hey There Little Electron, Why Won't You Tell Me Where You Came From? - 2 views

  •  
    A nice article explaining the principle of quantum superposition from the double slits experience. Nothing new here but still interesting to read :)

    I myself am quite a big fan of the one-electron universe paradigm :)))

The Highlight of the Scientific Calendar, 2014 - 7 views

  •  
    It's out there for TWO days and no one has posted it here yet? What's happening to the ACT...

    In any case, yet-another-year-ACT-didn't-make-it... Better luck next time.
  •  
    read them when they came out - as probably 90% of ACTers but did not see any of them worth posting ...
  •  
    I think e.g. de Tommaso et al. results have application in almost any business, ESA notwithstanding, in terms of implications for optimal office decor...

Practical Electrostatic Motor(?) - 3 views

  •  
    Apparently a spin-off company of the University of Wisconsin is developing non-magnetic motors. Maybe this could be useful for reaction wheels etc. on satellites that monitor the Earth's magnetic field... (preventing magnetic interference with sensors)

    Duncan, this is one for you! - you can probably even build one in your kitchen ...

Rocks Made of Plastic Found on Hawaiian Beach - 1 views

  •  
    Plastic may be with us a lot longer than we thought. In addition to clogging up landfills and becoming trapped in Arctic ice, some of it is turning into stone. Scientists say a new type of rock cobbled together from plastic, volcanic rock, beach sand, seashells, and corals has begun forming on the shores of Hawaii.

    The Anthropocene might just be on its way

Direct brain-to-brain communication demonstrated in human subjects -- ScienceDaily - 2 views

  •  
    In a first-of-its-kind study, an international team of neuroscientists and robotics engineers has demonstrated the viability of direct brain-to-brain communication in humans.
  •  
    Was just about to post it... :) It seems after transferring the EEG signals of one person, converting it to bits and stimulating some brain activity using magnetic stimulation (TMS) the receiving person actually sees 'flashes of light' in their peripheral vision. So its using your vision sense to get the information across. Would it not be better to try to see if you can generate some kind of signal in the part of your brain that is connected to 'hearing'? Or would this be me thinking too naive?
  •  
    "transferring the EEG signals of one person, converting it to bits and stimulating some brain activity using magnetic stimulation (TMS)"

    How is this "direct"?
