Truth was born after a hundred question marks.

Extended data writing background:
This article was written in 198 1. It was written for Keyuan magazine, which was newly founded in Anhui, and was first published in the first issue of the magazine.
During college, Ye Yonglie, as a student of chemistry department in Peking University, read many books on chemical history after class, such as General Examination of Chemical History by Professor Ding and Essays on Chemical History in China by Professor Yuan Hanqing. Later, it expanded from the history of chemistry to the history of science, which was also a lot of reading.
At the age of twenty, Ye Yonglie became the main author of 100,000 Why. One of his "skills" in writing "100,000 Why" is to start with interesting stories in the history of science, draw relevant scientific principles from them and answer "Why".
For example, "What is Water" starts from the story of British chemist priestley, and draws the conclusion that hydrogen burns in oxygen and becomes water, and water is composed of hydrogen and oxygen. Later, when he wrote scientific papers, he used vivid learning examples to demonstrate scientific themes and philosophies. This paper is a scientific paper, which was written under this background.
This paper mainly demonstrates and warns people that only by continuous exploration and discovery can we get the truth, that is, we should keenly discover problems, persistently think and solve problems in depth.
Only by "asking the truth in the end" and persistently looking for the source and the answer can we find the truth in real life. The full text is clear and easy to understand, and the beauty of intellectual wisdom shines between the lines.
