观察是科学发现的重要途径,是取得原始材料、扩大研究领域、构建科学假说、形成科学理论的基本方法.例如海王星的观察发现,既是一个新科学的发现,同时也是检验牛顿万有引力假说的一个强有力的证据.正是在一系列观察实验证据的支持下,牛顿的万有引力假说才转化为科学理论被大家接受.在物理 Observation is an important way of scientific discovery, and it is the basic method of obtaining original materials, expanding research fields, constructing scientific hypothesis and forming scientific theories, for example, the observation of Neptune is not only a discovery of new science but also a test of Newton’s universal gravitation hypothesis Strong evidence.It is supported by a series of observational evidence that Newton’s universal gravitation hypothesis is translated into a scientific theory accepted by all.In physical
