老师严肃地宣布:新学期要正式学习化学了,请各位同学熟悉元素周期表,最好能完整背诵它。这是大多数 人第一次接触化学这门学科的场景。"氢氦锂铍硼,碳氮氧氟氖",这张表格是人类理性与自然规律结合的 产物,是宇宙秩序的完美化身。 然而,人类究竟是如何发现元素的?在门捷列夫之前,人类要用什么样的符号或名字来称呼元素?化学究竟 是什么?这是个跨越千年的漫长故事。英国作家保罗·斯特拉森所著的《门捷列夫之梦:从炼金术到元素周 期表》,带我们回溯历史长河,见证了这张化学史上的巅峰之作诞生的全过程。 □悦迪 从假说到炼金术 人们聊到伟大的数学家时,常会说起欧拉的美丽公式、高斯尺规作图画正十七边形、阿基米德的尤里卡 时刻。聊到伟大的物理学家时,也常会为如何给牛顿、爱因斯坦、麦克斯韦、海森堡等大佬排座次而兴 奋不已。但聊到伟大的化学家时,大脑似乎很容易卡壳,除了门捷列夫、居里夫人之外,几乎空空如也。 显然,化学并不是一门知识从天而降的学科。《门捷列夫之梦》把时间倒回到2500年前。彼时,古希腊哲 学家们凭借观察和思考,已开始对世界本源"元素"的探寻。 2500年前,古希腊哲学家泰勒斯在米利都的山坡上散步,看到岩石里的贝壳化石,灵光一 ...

Group 1 - The article discusses the significance of the Poincaré Conjecture, a century-old mathematical problem that has captivated many brilliant minds, culminating in the work of Russian mathematician Grigori Perelman, who solved it but chose to reject the Fields Medal and a $1 million prize, leading to speculation about his disappearance from public life [3][4][10] - The book "Poincaré Conjecture: Pursuing the Shape of the Universe" presents a documentary-style narrative that chronicles the century-long journey to solve this conjecture, highlighting the allure of mathematics and the unique lives of mathematicians [3][4] - The Poincaré Conjecture is linked to fundamental questions about the universe's shape and boundaries, making it a pivotal topic in both mathematics and cosmology [3][4] Group 2 - The book "The Fascinating Chemistry: Molecules in Life" by Nobel laureate Ben Feringa takes readers on a journey through the molecular world, using everyday phenomena to unveil the mysteries of chemistry [6][7] - It covers various well-known molecules and their historical significance, from ancient Egyptian perfume recipes to modern drug breakthroughs, making complex chemical knowledge accessible and engaging [6][7] - The narrative intertwines scientific principles, historical anecdotes, and practical applications, illustrating the role of chemistry in critical moments throughout history [6][7] Group 3 - The book "Haier's Quality Management Path: From Zero Distance to Zero Boundaries" documents Haier's 40-year evolution in quality management, marking significant anniversaries related to its quality management practices [9] - It showcases Haier's innovative quality management strategies in the era of artificial intelligence and highlights achievements in three core business areas [9] - The text provides a comprehensive overview of Haier's quality management philosophy, practical explorations, and classic events that have shaped its approach [9]
