Researchers calculate the amount of information in the world, move on to calculate how much time they wasted on silly calculations
Have you ever wondered how much information there is in the world? No? Well, someone has. In fact, new research by a team at the USC Annenberg School for Communication & Journalism, led by Martin Hilbert, has gone ahead and done some calculations to that effect, and the results, while seemingly trivial, are rather interesting. Turns out that there's a ton of information in the world, and the rate of its production is ever-increasing. A few fun tidbits: the current capacity for information, including digital and analog devices, is 295 exabytes, and by their metrics, 2002 is considered the start of the digital age. By 2007, around 94 percent of information was stored digitally. The full research is in the February issue of Science Express, and a video describing their methodology is after the break.
California universities use iPads to report news, diagnose heart conditions; Penn State students are like, 'what's an iPad?'
As you know, colleges and universities love throwing in "free" gadgets to justify bumping up their enrollment fees. To this end, USC Annenberg has announced a new program to provide j-school students with iPads, digital cameras, and audio recorders to help them report the news. Now, don't get us wrong: we appreciate the importance (and we're big fans of) "the journalism," and if an upgrade from those long, skinny notepads to modern consumer electronics helps facilitate a new crop of Woodwards 'n Bernsteins, then so be it. But are these kids really supposed to type their front-line reportage with the on-screen keyboard? And haven't most students had access to proper laptops for years now? In other "iPad in education" news, UC Irvine's iMedEd Initiative is providing first year medical students with "a comprehensive, iPad-based curriculum," according to PhysOrg. The devices are equipped with all the necessary apps for note-taking, recording audio, and faculty will develop podcasts and archiving lectures. Our favorite part of all this? The "digital stethoscope," which interfaces with the tablet for listening to and recording a patient's heartbeat. Once recorded, it can be compared to a library of over 3,000 heart sounds that typify specific heart conditions. Thornton Melon never had it so good! [Thanks, Matt F]
