Science (from the Latin scientĭa, ' knowledge ') is a system that organizes and builds knowledge through testable 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, whether theoretical or practical. 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 through 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. To do this, 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 testable predictions referring to past, present and future observations. These predictions can often be formulated through reasoning and structured as general rules or laws, which account for the behavior of a system and predict how the 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 popularization efforts, both to bring science closer to the general public, as well as to facilitate understanding and collaboration between scientists from different fields.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.
