Sloan Survey Expands to Explore Larger Universe in 3D - 0 views

  •  
    And though we may be away from those holographic representations, the Sloan Digital Sky Survey will soon be entering its third phase, in an attempt to create the biggest 3D map of the universe created so far.

The Census Survey and the New York Times just ate my day » We Love DC - 0 views

  •  
    It's hard not to get lost in a data projection like the NYT's Mapping America: Every City, Every Block, which allows you to parse through 20 or so different projections of the American Community Survey data over the last five years from the Census Bureau.  When you can see the geographic correlations of education levels and income (check out the dividing line at 16th street in both cases), it's a stark reminder of the different Washingtons that exist. Be sure also to check out DCist's initial take (focused on demography and increase/decrease) and GGW's initial take (focused on population shift between wards) This is a data goldmine, and the sort of thing that yours truly is absolutely in love with. Parse through this with us over the next couple weeks.

Among Students, Web Connection More Important than Car - The Daily Stat - September 26,... - 0 views

  •  
    64% of college students in a global survey said that if forced to choose, they would opt for having an internet connection rather than a car. 40% said the internet is more important to them than dating, going out with friends, or listening to music. The Cisco Connected World Technology Report draws on surveys of some 1,400 students in 14 countries.Source: Is the Internet a Fundamental Human Necessity?

American Urban Lake Pollution Traced to Parking Lot Seal Coat - 0 views

  •  
    WASHINGTON - A black sealant sprayed on parking lots, driveways and playgrounds turns out to be the largest contributor to the rise of a toxic pollutant in urban lakes and reservoirs across America, according to a new U.S. Geological Survey study.

EPFL spinoff turns thousands of 2D photos into 3D images | KurzweilAI - 0 views

  •  
    Researchers in EPFL's Computer Vision Laboratory developed a computer-based modeling service that generates a 3D image from up to thousands of 2D shots, with all the processing done in the cloud. Since April, the EPFL startup Pix4D has been offering the modeling service with a fourth dimension: time. Now, individuals and small businesses looking for fast, cheap, large-scale 3D models can get them without investing in heavy processing, the company states. With Pix4D, users upload a series of photos of an object, and within 30 minutes they have a 3D image. The software defines "points of interest" from among the photos, or common points of high-contrast pixels. Next, the program pastes the images together seamlessly by matching up the points of interest. Much in the same way our two eyes work together to calculate depth, the software computes the distance and angle between two or more photos and lays the image over the model appropriately, creating a highly accurate 3D model that avoids the time intensive, "point by point" wireframe method. With Pix4D's 3D models, you can navigate in all directions as well as change the date on a timeline to see what a place looked like at different times of the year. The company is collaborating with several drone makers (including another EPFL startup,senseFly) to market their software as a package with senseFly's micro aerial vehicles, or autonomous drones. Pix4D's time element avoids waiting for Google to update its satellite data or for an expensive plane to fly by and take high-resolution photos. Farmers, for example, can now send relatively inexpensive flying drones into the air to take pictures as often as they like, allowing them to survey the evolution of their crops over large distances and long periods of time. And since the calculations are done on a cloud server, the client doesn't need a powerful computer of his or her own.

On the Pew Science Survey, Beware the Fall from Grace Narrative : Framing Science - 0 views

  •  
    This traditional fall from grace narrative about science argues for the need to return to a (fictional) point in the past where science was better understood and appreciated by the public... Yet you would be hard pressed to find this type of rhetoric in the peer-reviewed literature examining public opinion about science, the role of scientific expertise in policymaking, or the relationship between science and other social institutions.
