Nice job opportunity at ESA - 7 views

  •  
    Anyone's going to apply? Just so that I know my competition... ;-)
  •  
    damn!! they look for someone with the "greatest personal integrity" -- I am out

    I'm game :)) I'll pay for everyone's beers with my limitless paycheck after I get it!

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!

    Today we released the Astro Drone app. People that have the Parrot AR drone can freely download the game. While they fly their drone in the real world, they are trying to dock to the ISS in the virtual world. But the app is more than a game. Players can choose to participate in a scientific crowd sourcing experiment that aims to improve autonomous capabilities of space probes, such as landing, obstacle avoidance, and docking. If participating, the app extracts visually salient features from the images made by the drone's camera. The features are then combined with the estimates of the drone's state and uploaded. The data is then used in a research aiming to improve robot navigation.

    Visit the main ESA website and you'll be greeted with a 6-minute Rosetta promo movie by a kickass Polish artist... P.S. You can also find the video here. P.P.S It seems I've just discovered a way to hijack old diigo entries ;-)

Scientist: Four golden lessons : Article : Nature - 7 views

  •  
    An oldie but a goodie, " As you will never be sure which are the right problems to work on, most of the time that you spend in the laboratory or at your desk will be wasted. If you want to be creative, then you will have to get used to spending most of your time not being creative, to being becalmed on the ocean of scientific knowledge"

    already forwarded it to other researchers in desperation phase :-D :-D

PLOS Computational Biology: Ten Simple Rules for Organizing an Unconference - 1 views

  •  
    For future reference... At the same time, a crowdsourced article: "We began the crowdsourcing by collecting a list of possible rules for the article via a git-controlled repository" SVN would be so 2000-ish...

Nature Optics: Super vision - 6 views

  •  
    Taking images through opaque, light-scattering layers is a vital capability and essential diagnostic tool in many applications. The research group of Prof. Mosk of U. Twente have started doing experiments shooting optical lasers into opaque materials in 2007, and for surprise of everyone, it turn out the light intensity after the opaque material in their experiments was orders of magnitude bigger than expected. Following these results they succeeded in taking non-invasive sharp pictures of objects hidden behind a screen of opaqueness, the so referred Super Vision in this Nature overview article.

Mining the moon - 1 views

    Mining the moon - now we know that the Moon's poles hold millions of tonnes of water ice, firms in the US as well as the Indian and Chinese space agencies are planning to mine this resource and sell it to space missions as fuel.

NASA Vesta Trek - 2 views

  •  
    NASA Releases Tool Enabling Citizen Scientists to Examine Asteroid Vesta Vesta Trek is a free, web-based application that provides detailed visualizations of Vesta, one of the largest asteroids in our solar system. NASA's Dawn spacecraft studied Vesta from July 2011 to September 2012. Data gathered from multiple instruments aboard Dawn have been compiled into Vesta Trek's user-friendly set of tools, enabling citizen scientists and students to study the asteroid's features. The application includes: -- Interactive maps with the ability to overlay a growing range of data sets including topography, mineralogy, abundance of elements and geology, as well as analysis tools for measuring the diameters, heights and depths of surface features and more. -- 3-D printer-exportable topography so users can print physical models of Vesta's surface. -- Standard keyboard gaming controls to manoever a first-person visualization of "flying" across the surface of the asteroid. "There's nothing like seeing something with your own eyes, but these types of detailed data-visualizations are the next best thing," said Kristen Erickson, Director, Science Engagement and Partnerships at NASA Headquarters in Washington DC.

Electron spins controlled using sound waves - 0 views

  •  
    Cornell applied physicists have demonstrated an unprecedented method of control over electron spins using extremely high-frequency sound waves - new insights in the study of the spin of the electron. Crazy idea but, no further need for complicated quantum encryption techniques of sound signals?

'Superman memory crystal' that could store 360TB of data forever | ExtremeTech - 0 views

  •  
    A new so called 5D data storage that could potentially survive for billions of years. The research consists of nanostructured glass that can record digital data in five dimensions using femtosecond laser writing.

    Very scarce scientific info available.. I'm very curious to see a bit more in future. From https://spie.org/PWL/conferencedetails/laser-micro-nanoprocessing I made a back of envelop calc: for 20 nm spaced, each laser spot in 5D encryption encodes 3 bits (it seemed to me) written in 3 planes, to obtain the claimed 360TB disk one needs very roughly 6000mm2, which does not complain with the dimensions shown in video. Only with larger number of planes (order of magnitude higher) it could be.. Also, at current commercial trends NAND Flash and HDD allow for 1000 Gb/in2. This means a 360 TB could hypothetically fit in 1800mm2.
  •  
    I had the same issue with the numbers when I saw the announcement a few days back (https://www.southampton.ac.uk/news/2016/02/5d-data-storage-update.page). It doesn't seem to add up. Plus, the examples they show are super low amounts of data (the bible probably fits on a few 1.44 MB floppy disk). As for the comparison with NAND and HDD, I think the main argument for their crystal is that it is supposedly more durable. HDDs are chronically bad at long term storage, and also NAND as far as I know needs to be refreshed frequently.
  •  
    Yes Alex, indeed, the durability is the point I think they highlight and focus on (besides the fact the abstract says something as the extrapolated decay time being comparable to the age of the Universe..). Indeed memories face problems with retention time. Most of the disks retain the information up to 10 years. When enterprises want to store data for longer times than this they use... yeah, magnetic tapes :-). Check a interesting article about magnetic tape market revival here http://www.information-age.com/technology/data-centre-and-it-infrastructure/123458854/rise-fall-and-re-rise-magnetic-tape I compared for fun, to have one idea of what we were talking about. I am also very curious so see the writing and reading times in this new memory :)

    But how can glass store the information so long? Glass is not even solid?!

The Internet Archive's Windows 3.x Showcase - 4 views

  •  
    Travel back in time and play with the original Windows 3.11. back when using a computer still meant loading EMM386 in your config.sys ;) Remember that expensive big box of hardware you were so proud of? Now the whole thing is simulated in your browser. Using JavaScript. And still runs faster. This is a collection of curated Windows 3.x software, meant to show the range of software products available for the 3.x Operating System in the early 1990s.

    Awesome :) It's even got skifree!

Trees Crumbling in the Wind - 2 views

    Interesting to see the size of the tree doesn't influence the amount of wind it can stand against. Of particular interest to know when you can have a tree falling in your house/car here in the Netherlands
