Just after I blogged Aug. 2 about the huge 2.5 mile Tobin Bridge over the Mystic River/Boston Harbor and connecting the city with to communuties to the north, bits of concrete and metals shards started falling on the Chelsea Yacht Club damaging some boats. No one was hurt and Massachusetts Port Authority officials said the bridge, which carries 76,000 vehicles a day, is safe although they have stepped up inspections. The bridge turns 60 in 2010 and when traffic is bumper to bumper during rush hour, it gets a bit bouncy especially when an 18-wheeler tanker passes you by.
In May, officials announced the aging structure would be painted. In some cases that can cost more than actual bridge construction. Indeed that was the case 50 miles to the north on virtually the same highway (Route 1/95) with the Piscataqua River Bridge which opened in 1972.
The topic of highway and railroad bridges is a hot one with the Aug. 1 collapse of the I35-W Bridge connecting Minneapolis and St. Paul. Today’s quiz: how many gallons of paint will it take to paint the Tobin Bridge (no Googling allowed)?
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.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
