polygons

Polygon

A polygon is a flat shape consisting of straight lines closed in a chain or circuit.

A chain or circuit is that the lines that conform the polygon are closed making a closed shape

Ex:

There are endless poligons some of them are:

A example of a henagon or monogon  is :

A example of  a digon is:

A aperigon is an extraordinary shape because have unless edges but to imagine how is it I gonna a show you how is a aperigon in his regular form:

REGULAR POLYGON:

A regular polygon is a polygon that all their edges and angles are the same length a example of a regular polygon is a square.

Classifications:

A polygon can be classified in:

ü  Number of sides

ü  Convexity and no convexity

ü  Symmetry

ü  Miscellaneous

Elements of a polygon:

ü  Edges

ü  Vertex

ü  Perimeter

ü  Semiperimeter

ü  Internal and external angle

ü  Central angle

In a regular polygon even we can see:

ü  Center

ü  Apothem

ü  Diagonals

A poligon can be defined by its outline like:

Simple, if two of its edges no consecutives doesn’t intercept

Complex, if two of its edges no consecutives  intercept;

Convex, when its to traverse a straight line cuts it to a maximum of two points, which has all its angles less than 180 º.

Concave if a line passing through it can cut in more than two points, is the one with one or more angles greater than 180 º.

Regular, if you have their angles and sides equal, is the wing once it is equilateral and equiangular.

Irregular, if you have your angles and unequal sides;

Equilateral, which has all sides equal,

Equiangular, which has all its angles equal

Ethics - Discrimination and Recognition of Other:

The discrimination is a situation that lives with us, you can see this in school, neighborhood, home and even in your city.


But the real discrimination is useless, some people say that discrimination is nothing more than an act of envy, which disturbs another person by just being or have better things, but there are other ways in which discrimination arises.


For example:
In the 9/11, discrimination in United States increase, because the terrorist group was part of the Jewish religion. Then almost 70% of North Americans began to have a hatred for Jewish people, the departed, teased, insulted, there is even a movie that relates to that situation "my name is khan" show as a family with Jewish desendencias is destroyed by that situcion (the movie is based on real events).


The discrimination is a situation that needs to be improved.
that really gets us nothing. discrimination is only an act that leads to the non-recognition of the other.


The recognition of others is very necessary for us to live together so you have to apply in our lives.
we must live among all, regardless of religion, race, creed, sex, that is what the recognition of others to know that the other is different and accept it as is.


This video is about a song from the black eyed peas in this song speak about the problems that do not facilitate the recognition of others, is against discrimination.

Mysteries of the Universe III: Wormholes

Today, I’m going to continue with my series Mysteries of the Universe, as my topic is science and out there, in the universe, there are infinite mysteries, waiting for an answer, and it’s my job to show them to you for you to create your opinions. Today, we are going to know one of the biggest mysteries, the Wormholes.

In physics, the Wormholes are hypothetical topological features of the space-time that would be, fundamentally, a “shortcut” through space-time. For a simpler explanation, imagine space-time visualized as 2D surface. If this surface is folded along a third dimension, it allows one to picture a wormhole "bridge". A wormhole is, in theory, much like a tunnel with two ends each in separate points in space-time.

There is no evidence for wormholes, but in theoretical level they can be valid solutions for the equations of the theory of general relativity which contain wormholes. The first type of wormhole solution discovered was the Schwarzschild wormhole which would be present in the Schwarzschild metric describing an eternal black hole, but it was found that this type of wormhole would collapse too quickly for anything to cross from one end to another. Wormholes that could be crossed, known as traversable wormholes, could only be possible if exotic matter (matter which would somehow deviate from the norm and have “exotic” properties) with negative energy density (amount of energy stored in a given system or region of space per unit volume) could be used to stabilize them. Natural processes which would be predicted to form a wormhole naturally in the context of general relativity have been never found, although the quantum foam theory is sometimes used to suggest that tiny wormholes may appear and disappear spontaneously at the Planck Scale (an energy scale) and stable versions of such wormholes have been suggested as dark matter candidates (matter which neither emits nor scatters light or other electromagnetic radiation). It has also been proposed that if a tiny wormhole held open by negative mass cosmic string (a defect which may be formed during a symmetry breaking phase transition) had appeared around the time of the Big Bang, it could have been inflated to macroscopic  size by cosmic inflation.

the different forms of the holy spirit

The different forms of the holy spirit are much but in the grade that i am my teacher explain me that the holy spirit can transform in different elements for example water, fire, nature; but have always form of spirit of consolidation that is that the spirit have with other people and that the persons in need of the lot and they are going through in times of for moments difficult times in their lives, there are also forms of holy spirit of hope that consist with the people not have hope the spirit illuminated to this person and he  goes ahead in the works, in the family and in the life.

At the end this holy spirit is very important in all the life’s on the persons because is a security because this holy spirit was will accompany  old of his life’s this holy spirit represent a white dove that is the because it represents the third person of the most holy trinity.

Finally I resume that the Holy Spirit were in old parts of the world because the people need him in all the causes or in old the consequences, old the people believe him, for me the holy spirit is a represents of the maximum god because is very important to the life because ever abandoned otherwise help and blees every one to prays and who dont preys, because he is essential.

THE RESURECTION OF THE GOD

Old of this are true because the resurrection is more information but I explain bravely in that paragraphs.

Jesus is the key event of the Christian doctrine and theology. According to the New Testament, Jesus was crucified, dead and buried in a tomb, and resurrected three days later. The New Testament also mentions several resurrection appearances of Jesus on several occasions to his twelve apostles and disciples, including "more than five hundred brethren at once.

The maximum work of the god is that the resurrection of his son, no have witnesses. However it can be verified no evidence.

The empty tomb.  The four evangelists mention it; he is recognized even soldiers, priests and the roman authorities. Although no have a direct proof but is a special sign because is the first step in the recognition of the important success that is the resurrection.

Although there were not witnesses to the resurrection. If any of the risen;   The death of Jesus, along with his resurrection, are part of the foundations of the doctrine of salvation, which believes that through these events, mankind was redeemed from original sin that weighed on him from the first parents, allowing men can reach eternity In all these cases,  in all these cases, the physical bodies would come to live, indstichable from the situation before death. these resurrection remember the miracles of the old testaments prophecy in the scriptures represent the veiled announcement or another resurrection very different that of Jesus himself.

negative numbers

A negative number can be a problem for the students because is like the anti-positive number and its use is very different to another rational numbers.

In a dictionary a negative number is simply a number less than zero and also less than all positive numbers

They used to represent loss, debts, decreases ……

They are represented by the same numbers but only a different sing (-) example:-1,-2,-4500……..

A good example of a decrease is this:

If someone wins 200.000 Colombian pesos

But need to pay reparations, food…..and spend 300.000

200.000

-

300.000

=

-100.000

Negative numbers are used to put temperatures less than cero example:

 Here the blue bar is a bar for negative numbers

A element like water freeze at less of 0 degrees

But mercury freeze at -37 degrees

Sometimes the positives numbers need to be differentiated from positive numbers that’s why is used +4, +5´+500/32…..

To understand how the negative numbers are organized is used the numeric line is a great form to compare numbers from zero to left and right of it and measure the distance from a positive to a negative and negative to positive.

Whit this representation we can see that  the negative numbers are smaller as bigger is the number after the sign (-) this number is called absolute number.

the absolute value of a number is the number (positive) that results of  quit the sign, (+) or (-)

The number zero is a undefinited ( no negative , no positive) as we see in the image.

ETHICTS - HUMAN RIGHTS

For what is it?

The human rights are for guarantee a good life for every human in the world, just by being born and are a human you have the right to have rights.

Why they originated?

Is a long story, because in the entire story the humans search the form to have human rights, in Egypt, Europe, Asia, etc. But the human rights appear in the end of the Second World War.

Because the world needs to guarantee that an event like the Second World War happen again, so that every human being be respected regardless its beliefs, religion, social group, etc. Are to improve the world and the way we live.

There is now near-universal consensus that all individuals are entitled to certain basic rights under any circumstances. These include certain civil liberties and political rights, the most fundamental of which is the right to life and physical safety. Human rights are the articulation of the need for justice, tolerance, mutual respect, and human dignity in all of our activity. Speaking of rights allows us to express the idea that all individuals are part of the scope of morality and justice.

We have 30 humans rights, to all the live, but in some countries this rights, are not met like the right of a good education, and to be respected, to born in liberty, like this rights are not met.
