“Most important discoveries are accidental: it is usually while we are seeking the answer to one question that we come across the answer to another.”
Sample Essay
It could be said that almost no discoveries are accidental because human beings are always looking for something, whether it is peace of mind or the answer to the origins of life itself. Humans are a curious lot – always questioning their surroundings and looking for answers. However, it cannot be denied that many times, although it is not necessarily the usual situation, we find the answer to a question when we were looking for the solution to a problem, rather than the answer to that particular question.
To begin with, history is chock full of examples of “accidental” discoveries that have played tremendously important roles in human development. While there may be an argument about whether such discoveries were truly accidents or not, one cannot deny that many discoveries were based on a series of fortuitous events that were not necessarily what the researcher had planned. However, it is difficult to ascribe to pure accident many of the most famous “accidental” discoveries.
It is true that there have been many inventions and discoveries credited to discovery by accident. Velcro, nylon, x-rays, polyethylene, vulcanized rubber and sugar substitutes have all been discovered more or less by chance, or at least by an unplanned series of circumstances. One of the all-time greatest “accidental” discoveries in this category would have to be that of penicillin. Alexander Fleming, a Scottish scientist, found that a bacterial sample that he was studying had become contaminated with mold, which inhibited the further development of the bacteria. Although the discovery of the drug penicillin itself was an accident, Fleming had previously researched the development of antibiotics during World War I. Additionally, more than three thousand years ago, Chinese people used moldy soybean curd as a poultice for boils and other skin infections. Warm earth, containing mold and other fungi, was also used by some cultures as a first-line treatment against infection thousands of years ago. Even though the final naming and refinement of the ultimate drug that we now know as penicillin was discovered by “accident”, it was more than a mere accident that led to its discovery.
Similarly, one can look at the “accidental” discovery of vulcanized rubber. An experimenter named Charles Goodyear had become interested in the substance of pure rubber, which could be used for many things but still had problems in its natural state. It would become brittle in cold weather, and melt in hot weather, which made it unacceptable for use in most climates. Mr. Goodyear began conducting many experiments on the substance, combining the pure rubber with many different chemicals. However, it was a fortuitous event that led to his greatest discovery. One experiment led him to combine sulfur with the pure rubber, whereupon he accidentally dropped the mixture onto a red-hot stove. Rather than melting, the substance formed into a disk-like object. It maintained its ability to stretch even when he put it outside into the cold winter air. Although Mr. Goodyear had been trying for five years to fix the problems with rubber, he “accidentally” discovered the process of vulcanization, which gives rubber strength, elasticity and durability.
Both of these examples are among the most widely cited “accidental” discoveries that have made great contributions to modern society. Although the actual sequence of events that led directly to the discovery could be deemed accidental, it was the search for answers to a particular problem that led the scientists or researchers to look in that general area anyway. While we may not find the answer to exactly the question we were originally concerned with, it is in the pursuit of knowledge in a particular area that we will usually find the answer to the question at hand.

观点陈述型作文/[题目]
“最重大的科研发现都是随机偶然的:往往存在着这样的情况,当我们在寻找某一问题之答案时,我们碰巧获得了另一个问题的解答”。
[范文正文]
可以说几乎没有任何科学发现是随机偶然的,因为人类总是在为着某一事物或目标而寻寻觅觅,无论所要寻觅的东西是心境的平静,抑或是有关生命本身之起源的解答。人类实乃一充满好奇心的生物种类——总是在探究其所处的环境,寻求各种答案。然而,我们也不能否认,在许多时候,虽然并不必定是在经常性的情况下,当我们在寻找一个问题的答案时,会意外地发现另一个问题的答案,而不是原来那个特定问题的答案。
首先,人类历史充斥着在人类发展过程中曾发挥过极其重大作用的“偶然性”发现的实例。虽然对于这些发现是否真正属于偶然性事件可能尚有争论,但不能否认的是,许多这些发现基于一系列并非必然是研究人员计划好的巧合事件。但是,将许多最为著名的“偶然性”发现归诸于纯粹的巧合,亦是非常不切实际的。
诚然,有许多发明和发现已被人们归诸于随机性事件。维可牢,尼龙,X-线,聚乙烯,热补橡胶和蔗糖替代品等,无一不是通过那些或多或少是碰运气的过程而被发现的,或至少是经由一系列非人为策划的情况所致。在这一范畴中,青霉素堪称人类历史上最伟大的“偶然性”发现之一。苏格兰科学家Alexander Fleming发现他正在研究的一种细菌样本被霉菌所感染,而该霉菌遏制了细菌的进一步发育。尽管青霉素这一药物本身的发现纯属偶然,但是,Fleming在此之前已在第二次世界大战期间进行过抗菌素的研发。此外,早在三千年之前,中国人已使用发霉的豆腐作为膏药来治疗烫伤及其他各类皮肤感染。含有霉菌和其他真菌的热土数千年前也被有些文化用作防止传染的首要医治手段。尽管我们现在所知道的青霉素,其终极药物的最后命名及精炼是通过“凑巧”而被发现的,但导致其发现的并非只是一次偶然事件。
同样地,我们可以来分析一下热补橡胶的“偶然性”发现。一位名叫Charles Goodyear的实验人员对纯橡胶的物质产生了浓厚的兴趣。纯橡胶可用来做许多事情,但在自然状态下仍存在诸多问题。在寒冷的气候下,它会变得易于碎裂,但在炎热气候下则易于融化,这些问题使它在大多数气候状况下无法使用。Goodyear先生开始对这一物质进行研究,在纯橡胶中加入许多不同的化学品。但是,只是出于一次偶然的幸运事件,才得以导致了他那最伟大的发现。在一次实验中,他必须将硫磺和纯橡胶混合在一起。在实验过程中,他不小心将混合剂掉到一火红的炉子上。混合剂非但没有融化,相反,它形成了一个盘状物。即使当他把这一物质放到室外寒冷的隆冬空气中,它仍保持着伸缩的特性。虽然Goodyear先生五年当中一直在努力解决纯橡胶的种种问题,但他却是“偶然地”发现了热补这一过程,使橡胶具有了力度、弹性、和耐用性。
这只不过是许多最广为人们津津乐道的对现代社会作出巨大贡献的“偶然性”发现中的两个实例。尽管直接导致这些发现的一系列实际事件可被视作“偶然的”,但不管怎么说,正是对某一特定问题之答案的求索才导致科学家或科研人员朝着那个大方向进行探索。虽然我们并不一定能寻找到我们原初所关注的那个问题的确切答案,但在追求某一特定领域的知识的过程中,我们往往会寻找到所考虑的那一问题的答案。 |
