UNIT VECTOR

The vectors are, in the field of physics , quantities defined by its point of application, sense, address and value. Depending on the context in which they appear and their characteristics, they are classified in different ways. The idea of ​​a unit vector refers to the vector whose modulus is equal to 1 . It should be remembered that the modulus is the number that matches the length when the vector is represented in a graph. The modulus, in this way, is a rule of mathematics that is applied to the vector that appears in a Euclidean space. Another name by which the unit vector is known is the normalized vector , and it appears very frequently in problems in various fields, from mathematics to computer programming. It is possible to obtain the internal product or scalar product of two unit vectors by finding out the cosine of the angle formed between them. The product of a unit vector by a unit vector, thus, is the scalar projection of one of the vectors on the direction es...

UNIVERSAL VALUES

Before going fully into the in-depth analysis of the term universal values, it is important that we establish the etymological origin of the two words that shape it: • Value, comes from Latin and more specifically from the word “valere”, which can be translated as "be strong". • Universal, for its part, also emanates from Latin. More exactly we can establish that it comes from the word "universalis", which is equivalent to "belonging to the universe". A value is a quality that gives people, things or facts an estimate . The term is used to name the moral characteristics that are inherent in a subject ( piety , responsibility , etc.). Universal , on the other hand, is an adjective that is linked to what belongs to or relative to the universe. The concept refers to the set of all created things and that which is common to all of its kind. These two definitions allow us to get closer to the notion of universal value . Universal values ​​are fo...

URBAN ZONE

 The definition of an urban area varies according to the country in which it is described. In general, it is considered that an urban area is characterized by being permanently inhabited by more than 2,000 inhabitants . The updating of urban development models has caused population density , geographical extension and the planning and creation of infrastructures to combine to be key factors in the delimitation of this class of areas. Although it is not correct to generalize, it can be said that urban areas tend to have a higher surface price and a lower presence of employment in the primary sector than rural areas . On the other hand, urban areas offer a greater range of resources for people's  survival . In this sense, it should also be emphasized that more and more the different authorities of these cities are working at full capacity to ensure that their inhabitants not only have a greater number of resources to survive but also that they have the necessary mechanisms to en...
