英语翻译
For about three centuries we have been doing science,trying science out,using science for the construction of what we call modern civilization.Every dispensable item of contemporary technology,from canal locks to dial telephones to penicillin,was pieced together from the analysis of data provided by one or another series of scientific experiments.Three hundred years seems a long time for testing a new approach to human interliving,long enough to settle back for critical appraisal of the scientific method,maybe even long enough to vote on whether to go on with it or not.There is an argument.
Voices have been raised in protest since the beginning,rising in pitch and violence in the nineteenth century during the early stages of the industrial revolution,summoning urgent crowds into the streets any day these days on the issue of nuclear energy.Give it back,say some of the voices,it doesn’t really work,we’ve tried it and it doesn’t work,go back three hundred years and start again on something else less chancy for the race of man.
The principle discoveries in this century,taking all in all,are the glimpses of the depth of our ignorance about nature.Things that used to seem clear and rational,matters of absolute certainty-Newtonian mechanics,for example-have slipped through our fingers,and we are left with a new set of gigantic puzzles,cosmic uncertainties,ambiguities; some of the laws of physics are amended every few years,some are canceled outright,

我们研究科学、实践科学、使用科学来建造我们所说的现代文明已经约有三个世纪了.任何一种非生活必需的现代科技,从运河闸门到旋转拨号电话到青霉素,都是由这种或那种的系列科学实验所提供的数据而分析整合出来的.三百年对于测试一种新方法在人们生活中的作用来说似乎很长了,足够时间平息对于科学方法的严厉评价,甚至足够时间来决定是否要将之继续下去.在这一点上众说纷纭.
从一开始就有反对的声浪.十九世纪工业革命初期,反对声刺耳并伴随着暴力；在当下,它紧急召集人群在大街上日夜不停地声讨核能问题.“回到最初去”,这些声音说,“它们根本不起作用,我们已经试过了而毫无成效；退回到三百年前,让我们为全人类重新开始研究一些风险小的东西吧.”
总的来说,本世纪的重大发现无不是基于我们对自然的深切无知上的惊鸿掠影.那些曾看似清晰合理、绝对确定无误的事情（譬如牛顿力学原理）,都已从我们指缝间流失,留下的是一整套新的巨大谜题、无限的不确定和模糊不清；一些物理定律每过几年就会被修改一次,另一些则直接被取消了,
