Science and art mixed with our daily life. Every second, they change our life in an invisible way. But I think it is development of science that play a bigger role.    With improvement of science we can live a more efficient life. Consider First Industry Revolution, it is the first time human can take advantages of nature's power to complete work that we used to do ourselves in a low efficiency. And along with the Second Industry Revolution, cars and planes appeared and make it more efficient and easier to travel. And Third Industry Revolution brought a new way of communication and broaden our sight though technics. Taking cell phone as an example, when cell phone first came into our lives, it was big and had only one function-communication. Though years of development, they are now small and powerful. With our smart phones we can transfer money without going to banks and get all the informations we need form our cell phone. For instance, if I want to see a movie, I can check the cinema which is close to me and buy a tike ticket. As I am concerned science is changing our lives and even reforming them.    Also, art make our lives more colorful. But without science art can not be spread so widely. Consider music which have a long history, in early time people could enjoy it only in concert because music can not be recorded and replayed. But now days we can buy music on the web and enjoy it everywhere with our I-pod.    Tough art colored our lives. But it is science make our lives more comfortable; It is science make our lives more efficient and it is science bring art to our lives.
