With origin in Latin subject, the concept of subject lets describe the reality that can be detected by human senses and that conforms, in addition to the Energy, what is known as world or physical plane. It is, therefore, everything related to physical things and that has a meaning opposite to that of spirit.
It should be noted that matter occupies a place in the physical environment and represents the objective reality since it can be perceived in the same way by more than one person. For example: a tree that is 10 meters high is material, it is made up of matter. All the individuals with normal capacities they will appreciate the same tree with identical characteristics (height of 10 meters, etc.).
For experts in Physics, matter has associated energy and occupies a space-time location that makes it comparable with the fundamental laws of physical. Modern science considers matter to be an entity, field or discontinuity that can be understood as a phenomenon captured by the senses, capable of propagating through time and space at an identical or lower speed than that of the light and to which it is possible to link energy.
The mass matter, on the other hand, is the modality of matter that contains dough. This type of matter can be analyzed from a microscopic or macroscopic perspective.
In others contexts, in addition, the subject is the subject or theme that is developed in a literary or scientific text, the point or subject that it deals with and the different scientific and school subjects and disciplines: “Last term, my son failed four subjects”, “There is no one better than Dr. López in matters of labor disputes with large corporations”.
Organic and inorganic matter and the importance of recycling
Organic matter represents the molecules that we manufacture living beings, which are based on carbon and are usually bulky, present great complexity and diversity; some examples are carbohydrates or carbohydrates, nucleic acids, proteins and fats.
On the other hand, we have inorganic matter, which is created through reactions chemical that take place in nature. Its molecules are simple and of a discrete size, and we find them in minerals, salts and chlorides, for example.
It is worth mentioning that all living beings, in our constitution, present both organic and inorganic matter, since we cannot do without any of them. Plants, for example, produce organic matter starting from inorganic, through the well-known photosynthesis.
In recent decades, different movements have taken place to encourage recycling. At first, an attempt was made to educate people about the waste of paper, encouraging on the one hand to consume it in reasonable quantities and, on the other, to create new sheets from others that had already been used. With technological advances, nowadays it is possible to do without printed documents thanks to the importance that the Internet has acquired; for example, many banks offer the option of not sending physical correspondence, but digital correspondence to their customers.
In many countries it is mandatory to separate the waste in different types, whether it is glass, plastic, paper, or organic matter. In some places, there is another container for oil residues and even one for clothes. Despite the value of this initiative, there are still many obstacles to overcome, such as the fact that a large part of daily consumer products do not have a type of material that is easy to distinguish, which results in an imprecise classification.
