Engineering equations apply to much more than just engineering. Registered civil engineer and former Boeing structural engineer, Patricia Kramer, took equations normally used to calculate the structural integrity and placement of cargo doors on an airliner to explain the evolutionary record of early humans. "The equations can predict how much energy is required for something to move in space," says Kramer, now a University of Washington (Seattle, WA) doctoral candidate and lecturer in anthropology. "If you take them and develop models that take into account the different leg lengths for Lucy and modern humans, and calculate the different levels of energy required for each, the result is a comparison of how much energy is required for Lucy and a modern human to move at any speed." Lucy is the name of the 40%-complete skeleton of a small female Australopithecus afarensis, discovered by Donald Johanson in Ethiopia in 1974. Kramer found that Lucy and her colleagues walked through life in no more than a stroll, matching the environmental demands of the time. Call: (206) 286-6698 or e-mail: firstname.lastname@example.org.
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.
