科学史上有这样一件事:十九世纪三十年代,英国科学家法拉第通过实验,发现了电磁的相互感应作用。可是,这一重大科学发现,在当时并不为人们所承认。事隔四十年后,麦克斯韦在法拉第研究的基础上,写出了《论电和磁》一书,使这一理论得以确立。据称,原因在于法拉第对于这一科学发现表述“模糊不堪”,人们难以理解他的观点,而麦克斯韦的论述简明、准确,因此得到科学家们的肯定。这件事生动地表明,科学工作者辛勤劳动取得的成果,由于不善表达,所受到的损失如此巨大。由此看来,是否善于写作,并非“雕虫小技”。古人称写作文章为“经国之大业,不朽之盛事”,是有一定道理的。
In the history of science, there is such a thing: In the nineteen thirties, the British scientist Faraday found out the electromagnetic interaction effect through experiments. However, this major scientific discovery was not recognized by people at the time. After a lapse of forty years, Maxwell wrote the theory of electricity and magnetism on the basis of Faraday’s study, so that this theory can be established. Allegedly, because Faraday’s “vague” expression of this scientific discovery, it is difficult for people to understand his point of view, and Maxwell’s argument concise and accurate, so get the affirmation of scientists. This incident vividly shows that the hard work done by scientists has resulted in such a huge loss as a result of poor expression. Seen in this light, is good at writing, not “carving a small trick.” The ancients said writing articles are “a great cause for the country, an event of immortality”. There is a certain truth.
