大家都遇到过走一会儿鞋带就散开来、重新系好后又散开来的情况。这是怎么回事呢?有一些好奇的物理学家进行了研究,还得出了答案——别小看系鞋带,这里面可有大学问。鞋带打的结是一种绳结,从古代开始就有许多人研究绳结的打法和用途。古代中国人在10万年前就开始使用骨针缝东西。在数学里还有纽结理论这个分支,专门研究绳结。许多物理学家、生物学家、化学家也在研究绳结,因为生命密码DNA,还有许多分子都打着结。研究绳结可以 We all encountered the laces to walk for a while to spread, re-tied and then dispersed to the situation. What's going on? Some curious physicists conducted research and came up with answers - do not underestimate the shoelaces, which can be asked by the university. Lace knot is a knot knot, since ancient times, many people have studied the knot play and use. Ancient Chinese began using the bone-stitched sewn 100,000 years ago. There is also a kink in mathematics this branch, specializing in knot. Many physicists, biologists, and chemists are also researching knots, because the life-password DNA, and many others, are knotted. Research knot can be
