English Chemist Harold Kroto shared the 1996 Nobel Prize in Chemistry with Robert Curl and Richard Smalley for their discovery of Fullerenes (C(60;)), molecules composed completely of carbon (C(60;)) that form hollow spheres (also known as Buckyballs), tubes, or ellipsoids. These structures hold the potential for use in future technologies ranging from drug development and antimicrobial agents, to armor and superconductors. Harold Kroto was born in Wisbech, Cambridgeshire in 1939 and grew up in Bolton. Educated at Bolton School, he entered Sheffield University in 1958 to study Chemistry. During his time there he played tennis for the university team, illustrated the university's magazine covers, and played folk music with other students. Enjoying his time at Sheffield very much, he chose to stay on and complete a Ph.D. in Chemistry under Richard Dixon. Following graduation in 1964, Kroto went on to post doc at the National Research Council (NRC) in Ottowa, Canada where microwave spectroscopy became his specialty. After two years of study at the NRC he spent a year at Bell Laboratories. He then accepted a position as a tutorial fellow at the University of Sussex, where he was soon offered a permanent position. There, he applied his expertise in microwave spectroscopy to the field of astronomy and spent several fruitful years detecting long carbon chains in the interstellar medium. Upon hearing of the work of Richard Smalley at Rice, who developed a laser that could vaporize graphite, Kroto thought they could use Smalley's instrument to see carbon chains similar to those they had observed in interstellar matter. He suggested his idea for an experiment to Bob Curl, also at Rice. In 1985 he traveled to Rice to perform the experiment (and also to visit a half-price bookstore he'd heard about in Houston). Although he felt certain that the apparatus would create the carbon chains, the experiment revealed a totally unexpected result: the spontaneous formation of spherical shapes, which they called Buckminster Fullerenes in honor of the architect who popularized the geodesic dome. Though he is pleased to have received the Nobel Prize, Kroto does not believe in prizes or competition as a motivator for scientific (or athletic) progress. Rather, he believes that the pursuit of science or athletics should be simply for the enjoyment or interest in the subject matter, and he prefers to investigate subjects that other people aren't working on. Kroto has mixed feelings about the effect the prize has had on his life. On the one hand, he would like to be able to spend more time pursuing graphic design, something he has always deeply enjoyed. On the other hand, he now enjoys a sense of responsibility for supporting the scientific community. As an atheist, Kroto feels that science is, in itself, atheistic. He doesn't accept anything without evidence. Kroto expresses concern about people holding positions of power who do not use evidence as a basis for decision-making. "When they are prepared to accept one of 20-30 stories from thousands of years ago, I wonder what else they are prepared to accept when it comes to decisions which affect me?" Kroto is particularly worried about the effect of policies that require the teaching of non-scientific ideas, to the detriment of evidence-based scientific education. He points to the forced teaching of creationism in public schools and the existence of a "creation museum" in the United States as sources of misinformation that have given rise to "a whole generation of school children who've been abused."
英国化学家哈罗德·克罗托与罗伯特·柯尔和理查德·斯莫利共同获得了1996年诺贝尔化学奖,他们发现了富勒烯(C₆₀),即完全由碳(C₆₀)组成的分子,这些分子形成空心球体(也称为巴基球)、管子或椭球体。这些结构在从药物开发和抗菌剂到装甲和超导体等未来技术中具有应用潜力。哈罗德·克罗托1939年出生于剑桥郡的威斯贝奇,在博尔顿长大。他在博尔顿学校接受教育,1958年进入谢菲尔德大学学习化学。在那里期间,他为大学球队打网球,为大学杂志封面作画,并与其他学生一起演奏民间音乐。他非常享受在谢菲尔德的时光,选择留下来并在理查德·迪克森的指导下完成了化学博士学位。1964年毕业后,克罗托前往加拿大渥太华的国家研究委员会做博士后,在那里微波光谱学成为了他的专长。在国家研究委员会学习两年后,他在贝尔实验室工作了一年。然后他接受了苏塞克斯大学导师研究员的职位,并很快获得了永久职位。在那里,他将微波光谱学的专业知识应用于天文学领域,并在探测星际介质中的长碳链方面度过了富有成果的几年。听到莱斯大学理查德·斯莫利的工作后,他开发了一种可以汽化石墨的激光,克罗托认为他们可以使用斯莫利的仪器来观察类似于他们在星际物质中观察到的碳链。他向同样在莱斯大学的鲍勃·柯尔提出了他的实验想法。1985年,他前往莱斯大学进行实验(同时还去了他听说过的休斯顿一家半价书店)。尽管他确信该仪器会产生碳链,但实验却揭示了一个完全意想不到的结果:球形的自发形成,他们将其称为巴克明斯特富勒烯,以纪念推广测地线圆顶的建筑师。尽管他很高兴获得诺贝尔奖,但克罗托不相信奖项或竞争是科学(或体育)进步的动力。相反,他认为对科学或体育的追求应该仅仅是为了对主题的享受或兴趣,并且他更喜欢研究其他人没有研究的课题。克罗托对这个奖项对他生活的影响有着复杂的感受。一方面,他希望能够有更多时间追求平面设计,这是他一直非常喜欢的事情。另一方面,他现在对支持科学界有一种责任感。作为一名无神论者,克罗托觉得科学本身就是无神论的。没有证据他什么都不接受。克罗托对那些掌权者在决策时不将证据作为依据表示担忧。“当他们准备接受几千年前的二三十个故事中的一个时,我想知道在涉及影响我的决策时他们还准备接受什么?”克罗托特别担心那些要求教授非科学观念的政策的影响,这对基于证据的科学教育不利。他指出公立学校强制教授神创论以及美国存在的“创世博物馆”是错误信息的来源,这些导致了“整整一代学童受到了误导”。
