For many centuries，countless scholars have asked the question：What is beauty? As designers update the latest fashions and artists create their masterpieces, what is considered beautiful changes at an alarming pace. Fifty years ago，the full-figured Marilyn Monroe was a symbol of the American aesthetic(美学的)value；today，many Hollywood actresses different in appearance from Marilyn’s have taken her place. However，aesthetic values not only differ from generation to generation，but do so along cultural lines as well. Often, what is considered disgusting to one civilization is just the aesthetic appeal in another. Thus it is difficult to give an absolute definition(定义)of beauty. As fundamental(基础的)physicists，my colleagues and I like to believe that we are involved in a search for a beauty that affects definition. The beauty that we search for is not what is set up through the work of people and subject to the tastes, but rather what has been laid down by nature Physics allows its students to look past outer appearances，into a deeper beauty. As a human being，I am attracted by the visual appeal of a wave crashing on the beach. As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon. In truth，since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe，aesthetics have become a driving force in modern physics. Einstein and other later physicists have discovered that：Nature, as its most fundamental level，is beautifully constructed. The extraordinary simplicity of the laws that govern the universe is really breathtaking . As Einstein said, it would seem more likely that we should find ourselves living in a“chaotic(无秩序曲)world，in no way graspable through thinking”. Yet we are now closer than ever to a full understanding of the universe’s beautiful clockwork. As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels，we find that the beauty itself becomes much deeper. 小题1:The reference to“Marilyn Monroe”in Paragraph 2 mainly serves to___________.
