Nowadays engineering is not restricted in architecture or manufacturing, it has become the tool of diverse fields. Science is one of the most related fields of engineering. According to the claims of the article-Engineer the tools of scientific discoveries, engineering assists to explore the discoveries of biochemistry in the form of new microscopes and new biochemical methods. What’s more, engineering enterprises are crucial to improve the quality of long distance human space flight. Science needs engineering to be its material support and regards it as an adequate tool. Engineering is not only important in the scientific field, but also essential in making new energy-solar energy. “Engineers find ways to improve the efficiency of the cells and to lower their manufacturing costs,” stated in the article Make solar energy economical. New technology of engineering helps to build solar cells which have low cost and high capacity. It also improves the efficiency of solar energy absorption. With the help of new equipments, solar energy will gradually take the place of fossils. Besides making new energy, engineering also plays an important role in securing information system. There exists a new model called role-based access control (RBAC) model.( Role engineering of information systemPoniszewska-Maranda, A.) It is developed for the role engineering in the security of information system. This model is designed by computing engineers to control the access to the information system. It is classified as a key to the information base and also has the function of blocking rubbish information. Computing engineering becomes a useful tool in the information field. The world of engineering is expanding. Our society needs engineering to design and create new things. Engineering is now a widely used tool in diverse fields.
