Matter and energy make up the physical world.
Originating in the Latin matter , the concept of matter allows us to describe the reality that can be detected by the human senses and that makes up, in complement with energy , what is known as the 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 objective reality since it can be perceived in the same way by more than one person. For example: a tree that has a height of 10 meters is material, it is composed of matter. All individuals with normal abilities will appreciate the same tree with identical characteristics (height of 10 meters, etc.).
Matter according to physics
For physics experts, matter has associated energy and occupies a space-time location that makes it comparable to the fundamental laws of physics . Modern science considers that matter is an entity, field or discontinuity that can be understood as a phenomenon captured by the senses, capable of propagating through time and space at a speed identical or lower than that of light and at which it is possible to bind energy.
Mass matter , on the other hand, is the type of matter that contains mass . This type of matter can be analyzed from a microscopic or macroscopic perspective.
The term as a theme or issue
In other contexts , furthermore, the subject is the subject or theme that is developed in a literary or scientific text, the point or theme it addresses and the different scientific and school subjects and disciplines.
«Last quarter, my son failed four subjects» y «There is no one better than Dr. López in terms of labor conflicts with large corporations» son expresiones que muestran estos usos.
Separating waste according to the characteristics of its material favors recycling.
Organic and inorganic matter
Organic matter represents the molecules that living beings make, which are based on carbon and tend to be voluminous, 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 chemical reactions 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 from inorganic matter, through the well-known photosynthesis .
Waste separation and promotion of recycling
In recent decades, different movements have taken place to promote recycling. At first, an attempt was made to educate people regarding 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, today it is possible to do without printed documents thanks to the importance that the Internet has gained; For example, many banks offer the option of not sending physical correspondence, but digital ones to their clients.
In many countries it is mandatory to separate waste into different types, whether it is glass, plastic, paper or organic matter . In some places, there is another container for leftover oil and even one for clothing. 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 an easy-to-distinguish type of material, which results in imprecise classification.
