NATURE OF SCIENCE
Science covers the broad field of knowledge that deals with observed facts and relationships among does facts the word science come from the Latin word Scientia which means knowledge scientists study a wide variety of subjects for example some scientists search for clues to the origin of the universe other researchers examine the structure of molecules in the cell of living plants and animals still others investigate why we act the way we do or try to solve complicated mathematical problems but in whatever field they work all scientists explore the working of the world.
Scientists use systematic methods of study to make observation and collect facts they then work to develop theories that help them order or unify related facts scientists theories consist of general principles of laws that attempt to explain how and why something happens or happened science advances as scientists accumulate more detailed facts and gain a better understanding of these fundamental principles and laws.
A theory developed by a scientists cannot be accepted as part of scientists knowledge until it has been verified by the studies of other researchers in facts for any knowledge to be truly scientific it must be repeatedly tested experimentally and found to be true this characteristic of science sets it apart from other branches of knowledge for example the humanities which include religion philosophy and the arts deal with ideas about human nature and the meaning of life such ideas cannot be scientifically proved there is no test that tells whether a philosophical system is right no one can determine scientifically what feeling an artist tried to express in a painting nor can anyone perform an experiment to check for an error in a poem or a symphony.
Science also differs from others type of knowledge in that scientific progress depends on new ideas expanding or replacing old ones great work of art produced today do not take that place of masterpieces of the past but the theories of modern scientists have many ideas held by earlier scientists repeated observations and experiments lead scientists to update existing theories and to propose new ones as new discoveries continue to be made even many recent scientific theories will becomes outdated and will have to be replaced by better theories that can explain more facts in this way scientific knowledge growing and improving .
WHAT IS THE IMPORTANT OF SCIENCE?
Science has extensive influence on our lives it provides the basis of much of modern technology the tools materials techniques and source of power that make our lives and work easier the term applied science is sometimes used to refer to scientists research that concentrates on the development of technology the discoveries of scientists also held shape our views about ourselves and our place in the universe.
