      From proposing an seemingly rational conclusion to giving evidence by experiment,  this first step has an significant meaning more than ever. For so long, as the Average Joe, we've been observing the extinct phenomena but never  look deep into the scientific knowledge behind them. Hence,  scientists like Galileo, Rutherford , lead us to a brand new world that built upon bold hypothesis and rigorous verification. Also ,  the ongoing advancement of science makes some people like me ,who is weak in understanding the abstract principles and the fog of thousands of numerals as well as equations ,tend to be so grateful, because it is  their achievements that gives us hope to address various mysteries that we can never figure out.

      Science has always been an obscure topic .I can feel that I lost interest in it since 4th grade in primary school when the fist nature and science class was learned by us.  And science,as a subject in school, really troubles me till finally I choosed to learn literature and art in senior high school. However, as time goes by, I find that getting away from science did release me at first , yet the pay of my escape is so costly that I need to start all over again to learn science, especially the logic thinking. Speaking,writing, hearing, all this ,if not comprehend in  a scientific way, can never be done satIsfyingly. So after the twist and turn, science get back into my daily life,and I am appreciate that I understand the importance of it.
