The“Science Classics Series”constructs a series of knowledge frameworks centered on the“textual knowledge”of the original works. From the outside inwards，these frameworks consist of：“background knowledge”，“related knowledge”，and“subtextual knowledge”. The public should begin with the outermost framework and gradually progress inwards, ultimately reaching the“textual knowledge”framework. Through this step-by-step reading process，the public can not only avoid the initial difficulties associated with directly reading the original text，but also gain the necessary knowledge foundation for a deeper understanding of the original text，thereby paving the way for the popularization of science classics.
