Science (from the Latin scientĭa, 'knowledge') is a system that organizes and orders knowledge through verifiable questions and a structured method that studies and interprets natural, social and artificial phenomena. Scientific knowledge is obtained through observation and experimentation in specific areas. This knowledge is organized and classified on the basis of explanatory principles, either in a theoretical or practical way. From these, questions and reasoning are generated, hypotheses are formulated, scientific principles and laws are deduced, and scientific models, scientific theories and knowledge systems are built by means of a scientific method.

Science considers and is based on experimental observation. This type of observation is organized through methods, models and theories in order to generate new knowledge. For this, certain criteria of truth and a research method are previously established. The application of these methods and knowledge leads to the generation of new knowledge in the form of concrete, quantitative and verifiable predictions referring to past, present and future observations. Often these predictions can be formulated through reasoning and structured as general rules or laws, which account for the behavior of a system and predict how that system will act under certain circumstances.

Since the scientific revolution, scientific knowledge has increased so much that scientists have become specialists and their publications have become very difficult for non-specialists to read. This has given rise to various scientific dissemination efforts, both to bring science closer to the general public, and to facilitate understanding and collaboration between scientists from different fields.
