Science,in practice,depends far less on the experiments it prepares than on the preparedness of the minds of the men who watch the experiments. Sir Isaac Newton supposedly discovered gravity through the fall of an apple. Apples had been falling in many places for centuries and thousands of people had seen them fall. But Newton for years had been curious about the cause of the orbital motion of the moon and planets. What kept them in place? Why didn’t they fall out of the sky? The fact that the apple fell down toward the earth and not up into the tree answered the question he had been asking himself about those larger fruits of the heavens,the moon and the planets.
选项
答案
在实践中,科学与其说依靠事先准备的实践,不如说依靠实验观察者有所准备的头脑。艾萨克·牛顿爵士通过对苹果落地进行推理发现了万有引力定律。多少世纪以来,苹果一直在许多地方落到地面,成千上万个人看到苹果落地。而牛顿多年来一直对月球和行星绕轨道运行的起因感到好感。是什么力量使得它们处于现在的位置呢?它们为什么不落到天空之外呢?苹果向下落到地上而不是向上飞到树上这一事实回答了牛顿长期以来对月球和行星所存有的疑问。月球和行星是苍天中更大的果实。
