Sailing is a concept with multiple uses. It may be the object that has a wick inside, covered with a solid type fuel (such as paraffin or wax ). The candles are lit to provide luminosity. For example: "The power went out and I can't find the candles!" , "The fire occurred because the woman left her house and left a lit candle that fell on a table with a tablecloth" , "Tonight we will have a romantic dinner, by candlelight . " Although candles are used primarily to give a touch of intimacy and romanticism to a date, we cannot ignore that they are also widely used in magic rituals. Specifically, these are used one or the other depending on their color, since each one is associated with an element or objective: -White candles represent femininity, symbolize purity and serve to increase what is the strength of the spirit . -The yellow of these elements is associated with power, money and work. -Red candles, on the other hand, are associated with...

When determining the etymological origin of the term veda we have to go back in time. Specifically, we have to go to Latin because there we discover what word it comes from: vetare , a verb that can be translated as "prohibit by law." Veda is the action and effect of vedar (prohibit something by law or mandate). The term is also used to name the space of time in which hunting and fishing are prohibited (prohibited) . In this sense, the ban is usually applied to avoid the depredation of natural resources and to allow the reproduction (and, therefore, the subsistence) of the animals. For example: "Tomorrow begins the ban on silversides in Lake San Jorge" , "A Chinese ship was accused of violating the ban in US territorial waters" , "Fox hunting is banned in these lands . " Nor should we forget the existence of the non-profit organization called VEDA, Volunteers in Defense of Animals, which has been operating in Bolivia since the 199...

The term vector can be used in different ways. In the field of physics , a vector is a quantity that is defined by its point of application, its direction, its sense and its quantity. Coplanar , for its part, is a concept that is not part of the dictionary of the Royal Spanish Academy ( RAE ). On the other hand, the adjective coplanar does appear , which refers to the figures or lines that are in the same plane . Beyond the fact that the notion is incorrect according to the grammatical rules of our language, the idea of ​​coplanar refers to the points that are in the same plane (that is, they are coplanar points). When the point does not belong to said plane, it is considered not coplanar with respect to the others. The coplanar vectors , therefore, are the vectors that are in the same plane . To determine this question, the operation known as the triple dot product or mixed product is used . When the result of the triple scalar product is equal to 0 , the vectors...

Vector is a concept with several uses. In this case, we are interested in its meaning in the field of physics , which indicates that a vector is a quantity defined by its value, its sense, its direction and its point of application. Concurrent , on the other hand, is that which concurs (that is, that meets or coincides with something else). Vectors can be classified differently according to their characteristics . It is called concurrent vectors those traverse the same point . Due to the fact that, when passing through this point, an angle is created, the concurrent vectors are also called angular vectors. Suppose that two helicopters take off from the same point . One of the aircraft is heading east and the other is heading west. Both helicopters carry out a route that can be represented with a vector; as they have the same point of application, they are concurrent vectors. Take the case of an architect who draws the window of a room. In the plane , to represent the w...

A vector is, in the field of physics , a quantity that is defined through its point of application, its direction, its meaning and its quantity. According to their characteristics and the context in which they operate, you can differentiate between different types of vectors, such as coplanar vectors , the non - coplanar vectors , the opposing vectors , the resulting vectors , the unit vectors and the concurrent vectors , among others. In the case of collinear vectors , these are those that appear on the same line or that are parallel to a certain line. When the relations that maintain their coordinates are equal and the vector product is equivalent to 0 , two vectors are collinear. That is, according to the theory in the area of ​​Geometry, it can be said that two vectors are collinear at the moment that they have the same direction since, in that case, they are directors of parallel lines. Of course, they do not have to have the same meaning necessarily. We can f...

A variable is called a symbol that acts on the propositions, formulas, functions and algorithms of statistics and mathematics and that has the particularity of being able to adopt different values . According to its characteristics, it is possible to speak of different types of variables, such as variables quantitative the qualitative variables , the independent variables , the dependent variables and random variables . This time, we will focus on continuous variables. A continuous variable is one that can take any value within an interval that is already predetermined. Between two of the values, there can always be another intermediate value , which can be taken as a value by the continuous variable. These particularities differentiate the continuous variable from the discrete variable , which can only acquire one value from a set of numbers. There are gaps between successive values ​​that can be observed: that is, they are not “filled” with other intermediate v...

The first meaning of cowboy that appears in the dictionary of the Royal Spanish Academy ( RAE ) refers to what is linked to the shepherds dedicated to cattle . A cowboy, in this sense, is the one who takes care of and herds the cows. For example: “My grandfather, in his youth, was a cowboy, but then he emigrated to the city” , “We have come across four cowboys since we left town” , “Cowboys can walk for hours” . In each country , cowboys are known by different names, among which we find cowboys , charros , gauchos , llaneros or huasos , to name a few possibilities. In the case of cowboys, they are typical characters of American culture . A great skill riders who participated in the Civil War and faced Aborigines are known as cowboys: why films that discuss these topics are called cowboy movies or cowboys . Within computer animation cinema, the most prominent and memorable character is undoubtedly Commissioner Woody , a cowboy who has starred in the films of ...

In order to determine the meaning of the term vainglory, the first thing we are going to do is know its etymological origin. In this sense, we can state that it is a word that derives from Latin. Specifically, it is the result of the sum of two components of that language: -The adjective “vanus”, which can be translated as “empty”. -The noun "glory", which is equivalent to "fame", "honor" or "splendor". Boasting is the petulance or presumption of an individual regarding his actions or self- worth . The verb boast alludes to this act of boasting. For example: "I am fed up with the pride of this artist: he may have a lot of talent, but he lacks humility" , "I don't understand your pride: you have just made a big mistake and yet you are proud of your actions" , " You should not act out of pride, but out of solidarity ” . The term boastful, therefore, is also a conjugation of the verb boast: "The o...

The Latin. This is the language in which we can find the etymological origin of the word courage. Specifically, it emanates from the sum of the following parts: the verb “valere”, which is synonymous with “staying strong and healthy”; "Entity", which is equivalent to "agent", and the suffix "-ia", which can be translated as "quality". Courage is the encouragement or vigor in the execution of an action. For example: "It takes a man of courage for such a task" , "I did not have the courage to face Lord Wilson" , "The firefighter showed his courage by entering the burning house to rescue the children" , " The grandfather was cured thanks to the doctors and his courage ” . Courage is associated with heroism , gallantry, and courage . When a person is brave, they manage to overcome their fears or doubts and act decisively and firmly. Courage is shown in great acts (such as in a war or emergency), but als...

Vaca , a term that derives from the Latin vacca , is the female of the species Bos primigenius taurus , whose male is the bull . It is a mammalian animal that belongs to the bovidae family . The cow, which is part of the artiodactyls (since its limbs culminate in an even number of fingers), is herbivorous . This animal, therefore, feeds mainly on plants . Cows weigh more than half a ton and can be up to one and a half meters tall . Their domestication is believed to have started in the Middle East about 10,000 years ago . The rearing and use of the cow are part of cattle farming . The human being uses the cow to obtain milk (which, in turn, allows to generate numerous products) and meat. The body of the cow is also used to obtain leather. The beef is one of the most important foods in different cultures. In fact, most of the cow's body is consumed by man, from the brains (brain) to the tail. In Argentina , for example, the preparation and consumption of ...

  Gypsum is a term that comes from the Latin gypsum , although its origin dates back to the Greek language. It is hydrated calcium sulfate , which is usually white and is compact or earthy. Gypsum dehydrates through the action of fire and hardens quickly when mixed with water. This material is used in the field of construction , in artistic sculpture and in medicine (to keep a broken bone in place after a fracture). As an industrial product, gypsum is calcium sulfate hemihydrate and is often referred to as baked gypsum . It is sold in powder form, that is, ground. However, it should not be forgotten that there are many different types of plaster that are used by construction professionals. Among the most significant are black, matte, crystallized or white. Among the uses of plaster, its use as a paste for plasters, trimmings or joints and for the prefabrication of ceiling panels can be highlighted. Gypsum also works as a thermal insulator and can be used in the manufacture of cem...

 From the Russian tsar and originating from the Latin caesar (after Julius Caesar ), tsar is the title given to the emperor of Russia and the sovereign of Bulgaria and Serbia . Its feminine form is zarina . It is important to note that this noble title does not imply an imperial rank, but is the equivalent of the Slavic voice krol ( " king " ). In addition to tsarina, other terms associated with tsar are zarévich (the heir to the throne), zesarevna (the wife of the tsarévich ) and zarevna (the daughter or granddaughter of the tsar). The type of government developed by the Tsars was called Tsarism . The Tsar was an autocrat and exercised both political and economic power. He also considered himself the protector of the Russian Orthodox Church , which implies that he also had religious power. Ivan IV (or Ivan the Terrible ) was the first Russian monarch to adopt the title of Tsar in 1547 . From Pedro I ( 1721 ), the title of emperor began to be used officially...
