科学史上4个著名的梦

科学史上 4 个著名的梦科学史上第一个著名的梦德国化学家凯库勒（ F.A.Kekule ，1829－1896）是一位极富想像力的学者，他曾提出了碳原子四价学说和碳原子之间可以相连成-C-C- 链状结构这一重要学说。German chemist Kekule (F.A.Kekule ,1829-1896) is a very imaginative scholar.He had put forward the theory of tetravalent carbon atoms and the important doctrine of carbon atoms can be connected into -CC- chain structure.1865 年，他提出了苯的环状结构学说，他认为苯的结构可想像为6 个链形碳原子闭合而成。也就是我们现在所说的凯库勒式. In 1865, he proposed the benzene ring structure doctrine, he believed that 6 chain carbon atoms closed made the structure of benzene. That was the Kekule style.他曾经提出了多种开链式结构而又因其与实验结果不符而被一一否定所有的证据都表明苯分子非常对称，6 个碳原子和 6 个氢原子完全对称地排列、形成稳定的分子。He has proposed a variety of open-chain structures and denied them because they did not match with the experimental results.All the evidence showed that the benzene molecule are very symmetrical, 6 carbon atoms and the six hydrogen atoms are completely symmetrically arranged to form a stable molecule.1869 年 2 月，化学王国的宪法 -- 元素周期律。当时已经发现了63 种元素，科学家无可避免地要想到，自然界是否存在某种规律，使元素能够有序地分门别类、各得其所？In 1869 February, the constitution of the kingdom of chemical ---element periodic law. At that time ,already discovered 63 kinds of elements, the scientists would have to think about whether there was a law of nature, so that the elements can be arranged, orderly, play their proper roles? 35 岁的化学教授门捷列夫苦苦思索着这个问题，在疲倦中进入了梦乡。在梦里他看到一张表，元素们纷纷落在合适的格子里。醒来后他立刻记下了这个表的设计理念：元素的性质随原子序数的递增，呈现有规律的变化。门捷列夫在他的表里为未知元素留下了空位，后来，很快就有新元素来填充...
