"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
在歷史轉折的79週年，年輕世代有著自己的詮釋和感受，李承璦表示自己學習歷史更像是一種「解碼」當下的過程：「為什麼硬幣上是這些光頭？為什麼學校有教官室？了解這些根本原因後，我們才能談論分歧來自什麼？有人該為此負責嗎？我們該如何共存？」，详情可参考51吃瓜

We're all familiar with the high-pitched squeak of basketball shoes on the court during games, or tires squealing on pavement. Scientists conducted several experiments and discovered that the geometry of the sneakers' tread patterns determines the squeak's frequency, enabling the team to make rubber blocks set to specific frequencies and slide them across glass surfaces to play Star Wars' "Imperial March."
