OPEN SCIENCE, OPEN FUTURE. 泊松 Posong Simeon-Denis Poisson(S.-D.). 12304;生卒】:1781~1840. 法國數學家、力學家、物理學家。1781年6月21日生于法國皮蒂維耶,1840年4月25日卒于法國索鎮。 泊松原讀醫科,1798年進巴黎綜合工科學校改學數學,受到P.-S.拉普拉斯、J.-L.拉格朗日的賞識。1800年畢業后留校任教,1802年任副教授,1806年任教授。1808年任法國經度局天文學家。1809年巴黎理學院成立,任該校數學教授。1812年被選為法國科學院院士。 泊松一生從事數學研究和教學,他的主要工作是將數學應用于力學和物理學中。他第一個用沖量分量形式寫分析力學,使用后稱為泊松括號的運算符號;他所著《力學教程》在很長時期內被作為標準教科書。在天體力學方面,他推廣了拉格朗日和拉普拉斯有關行星軌道穩定性的研究,還計算出球體和橢球體之間的引力。他用行星內部質量分布表示重力的公式對20世紀...泊松的主要著作還有《毛細管作用新理論》和《熱學的數學理論》等。 普朗特 Pulangte Ludwig Prandtl(L.).

Open Science, Open Future. Miniature Origami Robot Self-folds, Walks, Swims, and Degrades. 機器人最基本的組態就是支撐的硬結構,活動的軟關節還有驅動的馬達。以往這些元件需要用不同的材料跟電機結構來完成,最近MIT跟慕尼黑工業大學展示了一種新的可能性-用自組裝的摺紙技術加上磁場激發來做成小的機器人。主要的構造很簡單,PVC跟磁性材料被包覆在兩層以紙或PS組成的薄片中,其中在放置一塊小的釹鐵硼磁鐵,包覆的這兩層薄片先以雷射切割,所以留下了可以彎曲的溝槽做為關節。然後把這機器人放到加熱板上,一但加熱,PVC開始變形,因為所夾的薄片有不同的溝紋,所以就自己摺起來成不同形狀,其中硬的板狀結構跟軟的活動關節也都有了。 其實,同樣的加熱摺疊原理去年已經展示過了,如同下面的影片,只是去年的馬達是外加的振動馬達,今年變成磁鐵震動. 65292;自我摺疊的實驗在近年也很多,如 自己折起來的薄膜!
