人类探索世界最基本的手段就是观察和实验。观察是指人类通过各种感官(如眼睛的视觉、鼻子的嗅觉等)认知世界的过程。观察的场所可以是自然环境,如,观察草原生态系统结构、观察不同生态环境的大气湿度等;也可以是人造环境,如,在实验室观察酵母菌形态结构,观察高浓度盐对草履虫行为的影响等。为了进行观察,人类还可以依靠各种仪器,如显微镜、质谱分析仪等,以此观察人的正常感官无法感知的世界。在探索世界的过程中,科学家们可以 The most basic means for mankind to explore the world is to observe and experiment. Observation refers to the human through various senses (such as eye vision, nose smell, etc.) to recognize the world’s process. Observing places can be natural environment, such as observing the grassland ecosystem structure, observing atmospheric humidity in different environments, etc .; also can be man-made environment, such as observing the morphological structure of yeast in laboratory and observing the behavior of high concentration salt to Paramecium Influence and so on. In order to observe, humans can rely on a variety of instruments, such as microscopes, mass spectrometry analyzer, etc., in order to observe the world’s normal senses can not be perceived. In exploring the world, scientists can
