Science can be defined as the study of the universe, its nature and the principles or laws that govern the whole or particular parts of it. Physics and chemistry are considered to be general studies while medicine and biology are considered studies of particular aspects of our universe. Science refers not only to the process of study, but also to the knowledge accumulated by people using scientific methods to observe the various phenomena that occur in our universe.
