It has been five years and literally tens of thousands of man-hours of work. Finally, the American Society for Testing and Materials (ASTM) F-24 technical committee has wrestled a new standard for the amusement park industry from the clutches of a variety of task forces evaluating everything from appropriate restraint devices to—for the first time—g-force limits. High g-forces have been thought to pose the risk of brain injuries. This standard is unique not only for its comprehensiveness, but also its global reach (not to mention that consensus building always takes time.) "It was a huge effort, really the biggest single standard that the amusement ride and device committee has worked on in its 25 years," says Greg Hale, chief of safety at Walt Disney World Resort and an outspoken advocate of safety standards. Hale and co-workers devoted hundreds of hours of their own time to this effort. Known as the Standard Practice for the Design of Amusement Rides and Devices—Z9591Z to those in the know—the standard piggybacks on an existing ASTM standard, but is unique in that it addresses detailed design criteria intended to assist engineers in designing rides that make people only feel like they are in peril. Active committee members hail from Australia, Bahrain, Brazil, Canada, France, Germany, India, Italy, Japan, Russia, Switzerland, The Netherlands, the U.K., and the U.S.—making for a truly global effort and ensuring that the best design practices from around the world made their way into the standard. Guess it's a small world, after all.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
