问题
A theory is a good theory if it satisfies two requirements: It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future conservation. Newton’ s theory of gravity was based on an even simpler model, in which bodies attracted each other with a force that proportional to a quantity called their mass and inversely proportional to the square of the distance between them.
选项
答案
能满足以下两个要求的理论算得上是一个好的理论:它必须要在包含少量偶然性因素的模型基础上,准确描述同类的大范围观察,同时它也必须对其长远生存与否的结果做出明确预测。牛顿的万有引力定律甚至建立在一个更为简单的模式上,该模式是身体之间通过一种引力相互吸引,该引力与他们的质量成正比,而与身体之间距离的平方成反比。
