After reading the chapter, I reviewed much knowledge about physics and enrich a lot of conception about the new theory.? What is much thoughtful is that about some so-called similar theory, such asspecialrelativity. It has been a common sense that it was found byEinstein. However, few ones know the deeper details about it , including me. Many descriptive or logical sentences are likely to be abstract for me. Sometimes It is tough to read it in Chinese. Moreover, reading it in English.. In the theory of relativity, the absolute space and absolute time does not exist.It means"static" is relativerather than absolute. For example , at the same moment, our situation or location is changing. In our daily life, time elapsed changelessly. While it is said that timeis the accessory.So it is hard to understand time is relative.
To be honest, when I receive the homework at the first time , I was astonished by the heavy burden that it has 12 pages. It seems to be impatient for me to read these related to physics. Anyway, I finished it narrowly.
