Beth, I agree. Its cool to use engineering to solve old and new problems. Its also important to maintain a creative mindset through imagination foster by fairytales. Also, the problem illustrates that not only men are good engineers but women as well. This problem should be presented to the Myth Busters to validate the math behind the solution.
Fun example and certainly one that could and should be used to encourage interest in STEM among girls. While the math may play out, I like your mom's version that the slippers were magic. Afterall, some fairy tales are better left to just that--fairy tales.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
