Limited portion of a body, the matter worked by and with certain use for the human being. Matter analyzed under the aspect of quality, “… with total abstraction of form, dimension and mass …”. The matter analyzed under the aspect of quantity, limited amount of matter. Matter is everything that occupies space, has mass and can be perceived, directly or indirectly, by the human senses, which can assume the solid, liquid and gaseous states. Without further ado, let’s go to the presentation of the stars of this text, matter and energy. In this way, I will leave for an upcoming text an explanation about the scientific method. At another time, also under the Philosophy of Science and Metaphysics topics, a discussion about materialist monism can to elucidate the reasons for this delimitation of the investigated objects. In this text, the focus will be the “basic” understanding of the objects of study that are fundamental to all scientific knowledge, matter and energy. Both aspects have particular characteristics in each field of scientific investigation, however, it is possible to establish a common basis for all scientific areas in relation to both aspects. In general, the development of a scientific approach involves the understanding of two contexts or aspects that, together, underlie scientific investigation, methodological (how to do science) and the object of study (what is investigated by science). In a way, to present an approach inspired by the work carried out by the professors that participated of GREF, that is, an initiation to scientific understanding as simple as possible, without entering into technical or formalist details. Introduce elements that help to recognize when in fact a statement, argument or theory is presented from a scientific perspective.

The purpose of this text is to answer the question of the title, offering an introductory perspective to science. In another time, under the topics of Philosophy of Science and Metaphysics, I will approach the nuances and difficulties involved in the concept of science.

The term ‘Science’, using an ostensive definition, indicates, here, areas of knowledge such as physics, chemistry, biology, geology, astronomy, etc., areas in which Nature (experiment and observation) always has the last word.

Therefore, it is not intended to be a definitive guide. This text offers only one of many ways of knowing the scientific world and the incredible richness and beauty of how it is possible to understand reality through science. The title question – Science, where to begin? – can be answered in several ways.
