The huge Maurice J. Tobin Bridge that links Boston and the communities to the north is just three years shy of its 60th birthday. Every morning and sometimes in the evening, the two and one quarter mile cantilevered truss bridge backs up with Boston’s famously awful bumper to bumper traffic. With the horrific Minneapolis I-35 bridge collapse last night, it makes one trapped in traffic on "The Tobin" all more nervous.
I have been mid-span which the roadway bump literally starts bouncing which is especially pronounced when a trick goes by. I’m told it’s supposed to do this to relieve stress. Nonetheless, it’s unnerving given you’re 135 feet above busy Boston Harbor represented at that point by the Mystic River. The sensation of potential danger is accentuated by a large and much publicized LNG depot about a fifth of a mile upriver.
And it’s an old bridge like many in America. On Sept. 10, 1973, an overloaded gravel truck was headed north and hit a bridge beam bringing down a section of the southbound roadway above. A similar accident occurred in 1995. Besides localized damage, the bridge as a whole stood tall. And 34 days after the 1973 accident, the bridge was threatened yet again by a giant fire that destroyed 18 city blocks in Chelsea, Mass.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
