把这一句，留给此刻的你
Hence, even in the domain of natural science the aid of the experimental method becomes indispensable whenever the problem set is the analysis of transient and impermanent phenomena, and not merely the observation of persistent and relatively constant objects.
因此，即使在自然科学领域，只要问题集是分析瞬态和非永久性的现象，而不仅仅是观察持久和相对恒定的对象，实验方法的帮助就变得必不可少。
