Science (from Latin scientia, translated as "knowledge") refers to any knowledge or systematic practice. In a strict sense, science refers to a system of acquiring knowledge based on the scientific method, as well as to the organized body of knowledge obtained through these links.
This article focuses on the strictest sense of the word. Although the two are strongly interconnected, the science as emphasized in this article is often referred to as experimental science to differentiate it from applied science, which is the application of scientific research to human needs specific.
Science is the effort to discover and increase the understanding of how the Universe works. Refers to both the:
Research or rational study of the Universe, led to the discovery of truths compulsively linked and restricted to the Universal Reality. Such study or research is methodical and compulsively carried out in accordance with the scientific method – a process of evaluating empirical knowledge.
Organized body of knowledge gained by such studies and research.
Science is knowledge or a system of knowledge covering truths, the more general and broad as possible, as well as the application of scientific laws; both specifically obtained and tested through scientific method. In these terms, science is something other than what is scientific, and can be defined as the set that contains the body of systematized and organized chronologically, of all scientific theories - with prominence usually given to the paradigms valid, as well as the scientific method and all the resources necessary for the development of the same.
From the definition it follows that a scientist is an essential element to science, and as any human being endowed with a brain of imagination that involves feelings and emotions; the scientist, certainly, you may also have beliefs - beliefs that go beyond the tangible reality, and may even be a theist or religious conviction. Science expressly requires that the scientist hold such beliefs away from their scientific work and the scientific theories with which you are working; by constituting these two elements - the science and the scientist - by settings certainly very different.
The correct understanding is a fact that science does not exclude believers, theists or religious; however, it is also a fact that science, thanks to the pre-requisites of the scientific method, entirely exclude the religious beliefs of his scientific theories, as well as the convictions are not measurable or testable, even though it might be considered to be transcendent to the real fact; being the science, by the paragraph establishing explicit in its definition stricto sensu - and by the absence of a fact contradictory - expressly skeptical and secular in the subjects that correspond.
The scientific method consists of the following elements:
• Characterization - Quantifications, observations and measurements.
• Hypothesis - Explanations, hypothetical of observations and measurements.
• Predictions - logical deductions from the hypothesis.
