In the case of good books, the point is not how many of them you can get through, but rather how many can get through to you.
Science is the observation, identification, experimental investigation and theoretical explanation of phenomenon. It is the study of physical, chemical and biological aspects of natural phenomenon. It deals with inherent properties of space, matter, energy and their interactions.
Technology is the application of scientific knowledge for the benefit of mankind. It includes the use of materials, tools, techniques and knowledge to make life more pleasant and work more productive. Whereas science is concerned with how things happen, technology focuses on making things happen.
