    用了一种稍稍不同的方法,把每七个元素分成一组,但使用了完全相同的前提。突然之间,这方法似乎很出色,视角很清晰。由于那些特点周期性地重复出现,所以这项发明就被叫做"周期表"。   据说,门捷列夫是从北美洲的单人牌戏获得了灵感,从别处获得了耐心。在那种牌戏里,纸牌按花色排成横列,按点数排成纵行。他利用一种十分相似的概念,把横列叫做周期,纵行叫做族。上下看,马上可以看出一组关系;左右看,看出另一组关系。具体来说,纵列把性质类似的元素放在一起。因此,铜的位置在银的上面,银的位置在金的上面,因为它们都具有金属的化学亲和性;而氦、氖和氩处于同一纵行,因为它们都是气体。(决定排列顺序的,实际上是它们的电子价。若要搞懂电子价,你非得去报名上夜校。)与此同时,元素按照它们核里的质子数--叫做原子序数--从少到多地排成横列。 这篇材料你能听出多少?点击这里做听写,提高外语水平>>

"Atoms cannot be [-2-] by the senses . . . they are things of thought," he wrote.

It was Einstein who provided the first incontrovertible evidence of atoms' existence with his paper on Brownian motion in 1905, [---5---] So the first real hero of the atomic age, if not the first personage on the scene, was Ernest Rutherford. Rutherford was born in 1871 in the "back blocks" of New Zealand to parents who had [-6-] from Scotland to raise a little flax and a lot of children (to paraphrase Steven Weinberg). [---7---] but in 1895 he won a scholarship that took him to the Cavendish Laboratory at Cambridge University, [---8---] for whom is named the speed of sound perceived The existence of atoms was so doubtfully held in the German-speaking world in particular suicide but this attracted little attention and in any case Einstein was soon to become consumed with his work on general relativity. emigrated Growing up in a remote part of a remote country, he was about as far from the mainstream of science as it was possible to be, which was about to become the hottest place in the world to do physics. 在道尔顿提出他的见解以后的一个世纪时间里,它仍然完全是一种假说。一些杰出的科学家--尤其是奥地利物理学家恩斯特•马赫,声速单位就是以他的名字命名的--还压根儿怀疑原子是不是存在。"原子看不见摸不着......它们是脑子想像出来的东西。"他写道。尤其在德语世界,人们就是以这种怀疑目光来看待原子的存在。据说,这也是导致伟大的理论物理学家和原子的热心支持者路德维希•玻尔茨曼自杀的原因之一。 是爱因斯坦在1905年以那篇论布朗运动的论文首次提出了无可争议的证据,证明原子的存在,但没有引起多大注意。无论如何,爱因斯坦很快就忙于广义相对论的研究。因此,原子时代的第一位真正的英雄是欧内斯特•卢瑟福,如果他不是当时涌现出来的第一人的话。 卢瑟福1871年生于新西兰的"内陆地区"。用斯蒂芬•温伯格的话来说,他的父母为了种植一点亚麻、抚养一大堆孩子,从苏格兰移居到新西兰。他在一个遥远国度的遥远地区长大,离科学的主流也同样很遥远。但是,1895年,他获得了一项奖学金,从而有机会来到剑桥大学的卡文迪许实验室。这里快要成为世界上搞物理学的最热门的地方。 这篇材料你能听出多少?点击这里做听写,提高外语水平>>

Unfortunately no one much noticed him. [---1---] Slipher was unaware of Einstein's theory of relativity, and the world was equally unaware of Slipher. So his finding had no impact. Glory instead would pass to [-2-] named Edwin Hubble. Hubble was born in 1889, ten years after Einstein, in a small Missouri town on the edge of the Ozarks and grew up there and in Wheaton, Illinois, a suburb of Chicago. His father was a successful insurance executive, so life was always comfortable, and Edwin [-3-], too. He was a strong and gifted athlete, charming, smart, and [-4-] good-looking—"handsome almost to a fault," in the description of William H. Cropper, "an Adonis" in the words of another [-5-] . According to his own accounts, he also managed to fit into his life more or less constant acts of valor—[---6---] It all seemed too good to be true. It was. For all his gifts, Hubble was also an inveterate liar. The Lowell Observatory, as you will recall, was a bit of an oddity thanks to Percival Lowell's obsession with Martian canals, which in the 1910s made it, in every sense, an outpost of astronomical endeavor. a large mass of ego enjoyed a wealth of physical endowments immensely admirer rescuing drowning swimmers, leading frightened men to safety across the battlefields of France, embarrassing world-champion boxers with knockdown punches in exhibition bouts. 斯莱弗第一个注意到光的这种作用,意识到这对将来理解宇宙的运动十分重要。不幸的是,谁也没有太多注意他。你会记得,珀西瓦尔•洛厄尔在这里潜心研究过火星上的运河,因此洛厄尔天文台是个比较独特的地方。到了20世纪的前10年,它在任何意义上都成了研究天文的前哨阵地。斯莱弗不知道爱因斯坦的相对论,世界也同样不知道斯莱弗,因此,他的发现没有影响。   荣誉反而属于一个非常自负的大人物,他的名字叫埃德温•哈勃。哈勃1889年生于欧扎克高原边缘的一个密苏里州小镇,比爱因斯坦小10岁;他在那里及芝加哥郊区伊利诺伊的惠顿长大。他的父亲是一名成功的保险公司经理,因此家里的生活总是很优裕。埃德温还天生有个好的身体。他是个有实力、有天赋的运动员,魅力十足,时髦潇洒,相貌堂堂--用威廉•H.克罗珀的话来说,"英俊到了不适当的程度";用另一位崇拜者的话来说,"美得像美神阿多尼斯"。用他自己的话来说,他生活中还经常干一些见义勇为的事--抢救落水的人;领着吓坏了的人穿越法国战场,把他们带到安全的地方;在表演赛中几下子就把世界冠军级的拳击手打倒在地,弄得他们不胜难堪。这一切都好得简直令人难以置信,但都是真的。尽管才华出众,但哈勃也是个顽固不化的说谎大王。 这篇材料你能听出多少?点击这里做听写,提高外语水平>>
