7、hing more complicated like a paper crane.The chances are that as you did it,you reflected on how inventive this traditional art is.Animals,boxes,flowers,boats: it all can be created from a single square or rectangular sheet of paper simply by folding it.No cutting,no pasting. But did you ever stop t

8、o think how the same techniques might be applied to engineering?Equipment that could be of real practical use?Origami meets the demand for things that need to be small when transported and large when they arrive,like the everyday umbrella.In fact,origami-inspired creations have already flown in spac

9、e;in 1995,Japanese engineers launched a satellite with solar panels folded like a map. “Its now mathematically proven that you can pretty much fold anything,” says physicist Robert J.Lang,who quit his engineering job eight years ago to fold things full time.Lang,an origami enthusiast since age six,a

10、dvised a well-known car manufacturer the best way to fold an airbag into a dashboard.He is currently working on a space telescopes lens that,if all goes according to plan,should be able to unfold to the size of a football field. At the other end of the scale,researchers are also working on tiny fold

11、ing devices that could lead to breakthroughs in medicine and computing.Theres no doubt that computers of the future may contain tiny,folded motors or capacitors for faster processing and better memory. Applications for origami engineering go further than many of us might imagine.“Some day,” says MIT

12、s Erik Demaine,“well build reconfigurable (可重构的) robots that can fold on their own from one thing into another,like Transformers.Too much like science fiction to be true?Maybethough you certainly wouldnt want to bet against it.” 【语篇解读】这是一篇说明文。折纸是一种具有创造性的传统艺术,而现在它已经被应用到技术工 程领域,人们利用折纸原理创造出了很多可折叠的装置。折纸
