What Is Direct Perception?

The direct observation method is a scientific observation method that uses the senses to directly perceive the research object to obtain information. There are two meanings. One is the opposite of instrument observation, which refers to the observation directly with the naked eye without the instrument. The second finger refers to the use of the instrument to directly observe the research object without the interference of the intermediary between the instrument and the research object. For example, when observing the sun's rays and rays on the ground with a telescope, spectrometer, and energy spectrometer, due to atmospheric interference, Some heavy charged particles are not observed, so it is called indirect observation. ^[1]
