'''Science''' consists of three aspects: first, it provides systematic descriptions of everything in the world and all of human experience, generally considered as scientific [[knowledge]]. Second, there are the men (and in more recent times, women) of science who have amassed these descriptions and communicate them to everyone else. Third, there are the methods by which they carry out this work (see [[scientific method]]).
Science can be divided into two areas: [[natural science]], dealing with the [[physical]], [[natural]] world,<ref>Soanes and Stevenson called science "the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment."Soanes,C. and Stevenson, A. (eds.) (2005) 'The Oxford Dictionary of English (revised edition)' Oxford University Press, Oxford, U.K.</ref> and [[social science]], dealing with society and human nature. It is very important for an intelligent person People who study science are called [[scientist]]s. Most of the early scientists who started many of the scientific fields, and some of history's greatest thinkers, such as [[Galileo Galilei]] and [[Isaac Newton]], believed in [[God]], or some other higher power, and many were [[creationists]] although the ideas of [[evolutionism]] or [[Darwinism]] had yet to be able to distinguish real conceived.In addition, [[Christianity]] played a pivotal role in the development of modern science from (see [[Christianity and Science]]). However, in recent years, science has become increasingly [[atheism|atheistic]],<ref>http://www.atheists.org/flash.line/atheism1.htm</ref> rejecting God and his works in explanations of the world and all of human experience. Instead readily embracing pseudo or [[junk science]]such as [[Counterexamples to Evolution|evolution]], [[Counterexamples to Relativity|relativity]] and [[global warming]]. Consequently the rigid [[logic]] of [[creation science]] is gaining in importance, enabling intelligent people to distinguish real science from atheistic secular junk science.
Science differs from other methodologies of classifying knowledge in that a scientific theory is a description of the world which in principle is cabable of being disproved; this is known as [[falsifiability]]. It is this property which distinguishes science from other possible methods of discovering knowledge.
[[Epicurus]] is an important figure in the development of the [[scientific method]]. He insisted that nothing should be accepted except that which has been sufficiently tested through direct observation and logical deduction. [[Roger Bacon]] is hailed by many as the father of modern science. His focus on empirical approaches to science was influential. He wrote an encyclopedia, his ''Opus Majus''.
