Eileen Award: Scoopit: Twitter: Facebook: Google+: iTunes: eMail: Advisory: From rotary to Siri: How the phone numbering system came and went The recent death of John E Karlin of Bell Labs, the father of the push-button phone and other innovations, has sparked a lot of reminiscing about land line phones. According to the New York Times, Karlin was also "the most hated man in America" for killing the named exchanges (like Butterfield 8). However the story of how our phone numbers got to be the way they are is a much longer and more interesting one. In 1950 it got really interesting, with the introduction of area codes. The designers wanted to minimize the number of numbers people had to dial, so all the area codes were set up to have 1 or 0 as the second number. The switches were set up so that if first number dialed was a 0 then it went to operator. If the second digit was 1 or 0, then it was an area code. If the second number was another number, then it knew it was a local rather than long distance number. That's how it was going to distinguish between 7 and 10 digit numbers. http://www.treehugger.com/gadgets/number-crisis-world-zone-1.html Bazooka shoots ping-pong balls at Mach speed The magic of physics can turn the mundane into something marvelous. Mark French, a mechanical engineering professor at Purdue University, designed a supersonic air-powered ping-pong ball cannon that shoots the lightweight object at speeds so fast I would consider the device a lethal weapon of science. A ping-pong ball reportedly blasts out of the special cannon at speeds equivalent to Mach 1.23 -- nearly as fast as an F-16 fighter jet. http://news.cnet.com/8301-17938_105-57569069-1/bazooka-shoots-ping-pong-balls-at-mach-speed/ Ocean Facts: In celebration of the upcoming premiere of DinoFish on Nat Geo Wild (Sunday, April 1, 10pm EST/PST), I’m excited to present the first of what we we hope will be a long series of comic strips by Dr. Byron Beekle.
