Summary

 This is my first time to do some reading notes . I just want to say it's a little difficult for me. Although I can  read this passage, I can not understand it accurately. I know myself better that I also have a long distance to the excellent people. So I should work hard more.

 Ok,continued my reading note. Through this passage, I know about the knowledge of science: "science is an ongoing search for truth ." This is really true. The scientific method with step 1:make observation step 2:form a theory step 3:experiments to test the theory or spculate. These methods reflect our life, when we want to finish sonething,we also need to follow these steps.

 This passage is about the history of science, so author writes this passage with time sequence,and he briefly introduce "first scientists and star-gazers ""house of wisdom ""birth of modern science ""elements,atoms and evolution ""uncertanity,infinity and secrets of life ".  

 This passage discussed the experiment of Rutherford 's alpha partical scattering. In it, a beam of alpha particals is ained at a thin foil of gold. Through this experiment, he found that the nucleus of an atom has a relatively small diameter compared with that of the atom and most of the mass of the atom is concentrated in the nucleus. This is a great achievement,which also provide references for backward researching.

At last, I will cite the author 's words that " As today's scientists buid on these and other achievements, the relentless search for the truth continues. It seems likely that there will always be more questions than answers,but future discoveries will continue to amaze ". Yes,our life need us to step foward and we need to persist on everything what we want to get. Science is a process ,while our life also maybe ,so work hard everyday an treasure present time.

Tomorrow is another day!
