A vehicle is a machine that allows you to move from one place to another. Vehicles can not only transport people , but also animals, plants and any type of object. Etymologically speaking, we can state that it is a word that derives from Latin, specifically from "vehiculum", which can be translated as "means of transport". However, this word in turn is the result of the sum of two clearly differentiated parts: the verb "vehere", which is synonymous with "transport", and the suffix "-culum", which is used to indicate an instrument. For example: “We need a vehicle to take the boxes to Pablo's house” , “The criminals were traveling in a dark-colored vehicle, which they parked two blocks from the place” , “The projectile hit a vehicle that was passing near the stadium ” . The cars , the trucks , the trucks , the ATVs and motorcycles are motor vehicles: mobilizing for action of a motor that works with any type of fue...

The Latin term vehementĭa came to Castilian as vehemence . This concept alludes to the property of vehement : that it has a lot of energy , strength , momentum or ardor . For example: "The young man vehemently defended his father, tired of the accusations" , "The Chilean midfielder hit the ball vehemently and scored the third goal for his team" , "I need a manager who vehemently disseminates the values ​​of this company among employees ” . Vehemence can appear in different settings. A person may speak vehemently, using a raised tone of voice or shouting with the intention of emphasizing their ideas or imposing themselves on others in an argument. Suppose a man is angry with his 13-year-old son because he found him smoking despite the fact that he had forbidden such action, explaining the damage that this habit generates. The father vehemently condemns the boy's behavior, details all the negative consequences that smoking can have on his heal...

The Latin word vegetarian came to our language as a vegetarian . It is an adjective that refers to something related to vegetarianism or to one who is adept at this food doctrine. Vegetarianism consists in not ingesting meat of any kind (beef, pork, chicken, fish, etc.): therefore, it limits the diet to foods of plant origin. Vegetarian individuals also tend to protect animals in other contexts (for example, rejecting the use of hides and skins for making clothing). Historians claim that vegetarianism already existed several centuries before Christ . Many people, at that time, were vegetarians since they adhered to the postulates of philosophers and religious that condemned all kinds of violence , including those that cause the death of animals to turn them into objects of consumption. After a time when it lost popularity, vegetarianism re-emerged in the 19th century . At present, there are several branches of vegetarianism according to how strict the diet is . In ge...

The first thing we are going to do is proceed to determine the etymological origin of the term vegetable. In this case, we find that with the fact that it emanates from a Latin word: vegetare , which can be translated as "grow". A vegetable is an organic being that grows and has life although it does not change its place by voluntary impulse . Vegetables, in fact, lack a locomotor system. The term is also used to name everything belonging to or related to plants . Vegetables can synthesize their own food through photosynthesis. They are made up of multicellular organisms (with eukaryotic cells ) and can measure from a few centimeters (like moss) to several meters high (like certain trees). The concept is little used in the scientific field, where it is preferred to speak of plants (a taxon studied by botany, which is a branch of biology ). The use of the notion of vegetable is limited to food and to nutrition or gastronomy. The plant foods include the vegeta...

From the Latin vegetatio , the term vegetation is used to name the group of plants that exist in a certain geographic space. It can be the flora of the land ( native vegetation ) or imported species. The notion of vegetation does not mention any specific taxon. In other words, the vegetation can be composed of plants with different characteristics and in very varied geographical situations. The concept allows to name from virgin forests to wild shrub assemblages or gardens designed by a landscaper. For example: "The vegetation of this province is exuberant" , "I want to go on vacation to a place where there is a lot of vegetation and animals" , "Pollution makes the vegetation of these types of cities increasingly scarce" . It is important to note that vegetation is not only important from a landscape or visual appeal point of view, but is also vital for oxygen generation , soil conservation and the so-called carbon cycle. There are diff...

A vegan is a subject who does not ingest food products of animal origin . Like vegetarians , vegans do not eat meat of any kind (pork, beef, lamb, fish, chicken, etc.) but, unlike ovolacte-vegetarians, they do not consume eggs, dairy, or honey . Veganism, therefore, is part of vegetarianism, which is a larger whole. A person who does not eat meat but does eat cheese, to name one possibility, is vegetarian but not vegan. Instead, all vegans are vegetarians. It is interesting to know that the term veganism dates back to the 1940s. And it was in 1944 when it was coined by the British Donald Watson, who also proceeded to found the Vegan Society. It is about a man who made the aforementioned veganism his philosophy of life from an early age, when he decided that he was not going to take anything that had animal origin, since he had been raised on a farm. There are many approaches or reasons that can lead a person to become vegan. Specifically, you can do it because you have he...

A vedette is a dancer , singer, and actress who performs in a music magazine or variety show. He is, in general, the most important figure in the work . As can be guessed from its constitution, the word "star" is of French origin, and in its original language it can be understood as the "star of a work". The vedettes do not always bring together the three talents listed in the previous paragraph: there are many examples of women who were exclusively dedicated to singing, such as Celia Gámez . In the same way, there are men who work as vedettes , so it is not an exclusive role for women. When there are several vedettes in the same show, they are usually numbered according to their importance in the plot: first star , second star , etc. It is important to note that the vedettes are usually accompanied by other dancers, comedians and artists in general. The first star can also be called a super star , and is the artist with the most important role i...

Vector is a term that derives from a Latin word and means "that leads . " A vector is an agent that transports something from one place to another . Its meaning, however, varies according to the context. A vector can be used to represent a physical quantity , being defined by a module and a direction or orientation. Its geometric expression consists of line segments directed towards a certain side, resembling an arrow . The speed and strength are two examples of vector quantities. Within this scientific field, and also of Mathematics, it is necessary to make it clear that there is a great variety of vectors. In such a way, that we can speak of fixed, parallel, sliding, opposite, concurrent, free or collinear, among many others. In the same way, it should be emphasized that a significant number of operations can be carried out with these elements. Among the most frequent are the sum, the product by a scalar, the obtaining of an ordinary derivative, decompositio...

The Vatican is a microstate that is located in the interior of Rome , the capital of Italy . It is, therefore, an enclave : a state that is totally surrounded by the territory of another state. When the term is written with a lower case initial ( Vatican ), it refers to the name of this nation. With an area of 44 hectares , the Vatican is the smallest country in the world. It is also one of the least populated, with a number of inhabitants that does not reach a thousand. The importance of the Vatican in the international context lies in the fact that it houses the Holy See , which is the episcopal jurisdiction of the Pope . The Catholic Church , in this way, has its base in the Vatican territory. The Vatican is a theocracy since its head of state is the Pope . In this European country there is no democracy : its inhabitants do not elect the rulers. The Vatican can also be considered an absolute monarchy because the Pope gathers control of the executive, legis...

Even Latin you have to go to be able to find the etymological origin of the vast term that now occupies us. When moving to that language, we come across the fact that this word emanates from "vastus", which can be translated as "desert or void". Vast is an adjective that refers to that which is extended, dilated or very large . The vast, therefore, is the opposite of the limited or small . For example: “The king exercised his dominion over a very vast territory that stretched for thousands and thousands of kilometers” , “The club announced the signing of a player with a vast experience in the European leagues” , “I have completed a vast journey to get here ” . The notion of vast can be applied to physical (concrete) or abstract (symbolic) questions. A vast desert is a large desert area, just as a very vast plain is a flat region characterized by its dimensions. This can be physically verified with a measurement . Instead, talking about vast knowledge ...

The first thing to do to know the meaning of the term vessel is to begin by discovering its etymological origin. In this case, we can say that it is a word that derives from Latin, since it is the result of the sum of these two elements of that language: -The noun “vasum”, which can be translated as “container”. -The suffix “-ija”, which is used as a diminutive. A bowl is a concave element that is often used to serve food , whether solid or liquid. These pieces are also used for decorative purposes and to store different types of objects. For example: "When I arrived at the refuge, they offered me a pot with chickpea soup" , "The young man hid the money in a pot and left the place" , "The aborigines used to collect pearls and then wash them in jars with water ” . The man vessels manufactured since over 12,000 years , according to what can be inferred based on various archaeological finds. Many ancient peoples who dominated pottery made clay ...

From the Latin vascularius , vascular is an adjective that is used in biology , zoology and botany to name what belongs to or is linked to vessels. A vessel is, in this sense, a channel that allows the circulation of blood or lymph in the body of a person or an animal, or sap or latex in the case of a plant. Sometimes we speak of the vascular system to name the circulatory system , which is the structure of the anatomy that includes the cardiovascular system (which conducts blood) and the lymphatic system (dedicated to conducting lymph). The vascular tension is that which appears on the walls of the ducts that allow the transport of blood. Said tension is produced by the pressure of the circulating liquid and by the elastic characteristics of the walls themselves. The cerebrovascular accident (CVA) , also known as stroke, is a type of disease that is characterized by sudden blockage of blood flow to the brain. This fact can generate various symptoms, such as faci...

Vassal is the one who, in ancient times, was obliged to pay fiefdom . It was the subject of a sovereign or any other type of supreme government , and it was linked to some lord (noble) through a bond of vassalage. The concept is typical of feudalism , a system of social organization that prevailed in western Europe between the 9th and 15th centuries . This society was based on the cultivation of the land by the serfs or vassals, who had to deliver part of their production to the lord (who, in turn, was loyal to a king). The vassal was the man who requested protection from a nobleman of superior rank (from the point of view of the social hierarchy) and who swore allegiance to him on his behalf. Both established a vassalage contract that implied mutual obligations. The lord granted the usufruct of a fief to the vassal, who administered it and took advantage of his income, although without having the property. The lord received part of the agricultural production in exch...

Vassal is the relationship that, in ancient times, an individual maintained with his lord . Said bond implied loyalty and, in turn, dependence and submission : the vassal had to provide military and political assistance to the lord, who in return gave him land for his usufruct. The vassalage was regulated by a bilateral contract (with obligations for both parties). If the vassal or lord committed a serious breach, the bond could be dissolved. Importantly, the relationship was forged between two free men (a commoner and a noble, or a noble of lower status and a noble of higher status). Everything began with a ceremony of homage and investiture , in which said contract was consecrated so that the relationship of vassalage began to take effect. In short, the vassal had to rest his hands on the lord's and declare himself "his man", in addition to swearing loyalty to him . Then, the lord gave the vassal a branch or a handful of land to symbolize the lands he...

From Latin variĕtas , variety is the property of that which is various (unequal, dissimilar, dissimilar, uneven, heterogeneous). Variety, therefore, is the grouping of diverse elements or dissimilarity in a certain unit . For example: “In this restaurant, there is an impressive variety of food” , “You can't complain, son: you have a great variety of games to choose from” , “Our company tries to offer the widest variety of options on the market” , “ This store sells nice clothes, but it doesn't have variety . " Variety implies diversity and, therefore, broadens a certain repertoire or range of possibilities. If there is no variety, all the elements are the same and offer the same benefits. That is why variety, in all areas, is positive. In this sense, we have to underline the existence of a popular saying that uses the term we are addressing. It is about "variety is taste." In this way, with the said Spanish saying, what we try to convey is that t...

The notion of variance is often used in the field of statistics . It is a word promoted by the English mathematician and scientist Ronald Fisher ( 1890 - 1962 ) and serves to identify the mean of the quadratic deviations of a random variable , considering its mean value . The variance of the random variables, therefore, consists of a measure linked to their dispersion . It is the expectation of the square of the deviation of that variable considered against its mean and is measured in a different unit . For example: in cases where the variable measures a distance in kilometers, its variance is expressed in kilometers squared. It should be noted that the dispersion measures (also identified with the name of variability measures ) are responsible for expressing the variability of a distribution by means of a number , in cases where the different scores of the variable are very far from the mean. . The higher the value of the dispersion measure, the greater the variabili...

The Latin word variatio came to Castilian as a variation . This is how the act and result of varying is called : changing, altering. The concept has multiple uses according to the context. In the field of genetics , variation refers to the changes that occur in the genes of a species or population. Genetic variation is linked to evolution . The alternative forms of genes located in the same position on homologous chromosomes are known as alleles , whose expression defines various traits. If there are many alleles for a gene, one can prevail over the others and thus natural selection occurs . Therefore, genetic variation contributes to the evolutionary process . In the field of music , on the other hand, variation refers to an altered repetition within the framework of a composition . It is a technique that leads to reiterate, with alterations, a rhythm, a melody or another element throughout the work. The main theme, thus, is imitated in subtopics. Those imitation...

Derived from the Latin term variabilis , variable is a word that represents that which varies or is subject to some type of change. It is something that is characterized by being unstable , fickle and changeable . In other words, a variable is a symbol that identifies an unspecified element within a certain group. This set is usually defined as the universal set of the variable ( universe of the variable , on other occasions), and each piece included in it constitutes a value of the variable. For example: x is a variable in the universe { 1 , 3 , 5 , 7 }. Therefore, x can be equal to any of the values ​​just mentioned, with which it is possible to replace x with any odd number that is less than 8 . As you can see, variables are elements present in formulas, propositions and algorithms, which can be substituted or can acquire, without ceasing to belong to the same universe, different values. It is worth mentioning that the values ​​of a variable can be framed wit...

Variability is the property of that which is variable . This adjective, which comes from the Latin word variabĭlis , refers to what varies, changes or is modified . For example: "Today's great climate variability is a consequence of human pollution" , "I recommend that you check with different banks before taking out the loan: there is a significant variability of the conditions according to the entity " , " The variability of symptoms makes it a difficult disease to diagnose . " Genetic variability is called the changes that are registered in the genes of a species or a population. This variability is a consequence of the natural selection process , which develops when nature selects different alleles that are modified so that the species can evolve. In this way, the greater the genetic variability, the greater the speed in the development of evolutionary changes. Importantly, genetic variability can be caused by the combination of ...

Vaporization is the act and consequence of vaporizing . This verb , on the other hand, can refer to transforming a fluid into steam by means of heat or spreading a fluid in drops of reduced size. Vaporization, therefore, can be the change of state from a liquid to a gas. This process can be carried out in two ways: when the passage from liquid to gaseous takes place throughout the mass of the substance, it is called boiling . It is called boiling point , in this context, the temperature that makes a liquid, at a certain pressure, boil and begin to undergo the aforementioned change of state; If the latter only takes place on the surface of the liquid, the phenomenon is known as evaporation . The enthalpy of vaporization , on the other hand, is the energy required for a unit mass of a liquid substance, which is at atmospheric pressure and in equilibrium with its vapor, to completely transform into a gas. For its part, the term enthalpy is defined as a thermodynamic q...
