Because my major is liberal art and I hardly read some books related to science, physics or other subjects , I deeply lack the knowledge, even the common senses in them. After reading this article , I have had a basic theory of science and its structure. It's no doubt that there are many new words and professional terms for me. In the process of reading, I enrich my knowledge as well as learn these new vocabulories.
As far as I am concerned, the structure of this article is clear and logical, every part has its own subtitle that helps me know the main topic of this part. Apart from this, I can find out many examples or key words about the topic, including some scientists ,discoveries , theories and so on. In some parts , chronological order is clear as well.
Perhaps I am unfamiliar with such kind of topic or subject, at the beginning of reading, I feel a little bit tough and confused. But after repeated reading, I can gradually understand the meaning and logic.
I hope that I can be persistent and make an improvement in the following days.
