THE LIFE OF A STAR
Certainly, the stars are one of the most important and amazing things in the entire Universe. In this case, I will talk about these awesome Astros. First, we found that the stars are objects that are able to transform hydrogen into helium by thermonuclear reactions. In the Universe are approximately 200 thousand million stars, however, not all have the same size and the same temperature, some of them are big and blue and others red and small. The course of the life of a star is determinate by its size.
The ride begins by the formation of the star, here, the Astro born from a cloud of spatial dust and gas. The pressure and the temperature into the new born star are very elevated, so, the matter around the star tends to be evaporated and the rest to turn around it by the gravitational energy of the Astro. At this moment, the star is very immature, requires time to grow up and start to transform hydrogen into helium.
Once the star grew up the enough, the temperature and the pressure into the center of it, produces the fusion of four hydrogen atoms into one of helium, releasing energy through photons. These conversions produce more matter than the necessary to form a helium atom, so, the rest of the mass is transformed into energy. All the stars, doesn’t matter if they are big or small, realizes this process. If the star has a similar mass as our Sun, when there are no more hydrogen to transform, the Astro starts to convert the helium into oxygen and carbon. These transformations produce that the star goes to the next stage, the stars pass to be a Red Giant. Then, finally ends its days as a white dwarf.
When the star is so much bigger than our Sun, the oxygen and the carbon that was produced in the center of the Red Giant begin to be transformed into more complicated elements, like neon and silicon, until the iron. All these reactions released energy, because the mass produced is bigger than the necessary, but from iron, the reactions requires more matter, so, the energy is converted into matter. The process uses a very big part of the star’s energy, this will cause an explosion as a Supernova. Then, the star will form a neutron star or a black hole.

about me and the university
It’s hard to believe that ten years ago my parents went me to C.U. to know the place where they studied and knew, and now I´m going to study there in a few months. I remember that in that occasion they gave me a tour in the University, they took me to meet their faculties. My father studied in the Faculty of Engineering and my mother in the Faculty of Philosophy and Letters, but they accidentally day met in the “islands”. Perhaps that coincidence moment is the responsible that I can be writing this text right now.
However, I’m not here to talk about how my parents met, today I’m going to tell you about how I feel knowing that I will entrance to the University soon. As you could read in the last text, I decided to study Chemistry, and surely I will do it in the Faculty of Chemistry. I was very excited to finally can start to take some lessons in C.U., so all this year I didn’t feel sad for the fact that I won’t see my friends as often as I can now, I think that the feeling was blinded by the emotion of finally reach one of my goals. The truth is that I tried to don’t think about it, I learned that the best thing we can do is use and enjoy the opportunities that the life gives us everyday instead of be sad because the stages finishes. But, fortunately or not, the things don’t go as we want all the time. I’m saying this because this Friday, the last classes day, when our final lesson finished, I really don’t know what happened in my mind in that moment but when I saw to one of my best friends outside the classroom I could only say: We already done it. Then I started cry and he came to me and hugged me, the rest of my “crew” did the same, everyone putted the face that shows that you want to cry. We have only shown sadness in this moment, but surely we will cry a lot the next thursday because we decided to prepare a speech for all the group and say it in that day.
In one hand I feel this way about the school and stage change, I will miss all my friends, but in the other hand are the emotion and the feelings about my entrance to the University. Certainly I’m very excited for the fact that finally I will be studying what I want, where I want, but also I’m scared for what could come with it. I have interviewing some students and teachers about the career and everyone tell me that it’s one of the most difficult things to study; I think that I will know it when I’ll be there. I’m really in love with Chemistry, anything makes me feel the same, and I can pass my whole life knowing more and more about it. I want to make something important for the humanity, not for the awards or the fame, only for the pleasure of knowing that I used my life to something important, that I didn’t came to life only to waste oxygen. It doesn’t matter how much cost me reach this goal, but I will, it’s a promise that I made me time ago.
Sometimes the people didn’t know how to organize themselves, some people only dedicate them entire life to work and others not. I really don’t know how difficult will be the career for me, but is a fact that I will put all my determination to can be one of the best chemist in the country; but also is true that won’t miss that I’m alive and that there are other people around me. My family is behind me and I know it, so, I just want to can give them back some of all that they gave me
THE FRIENDSHIP
In my entire life I always take good decisions about my friends, in this text I will tell you some about them. A friendship, for me, is relationship that you set with one or more persons where you can put your confidence, they will be there always that you need it, in good and bad times, in the poverty and in the richness, in health and in disease… Well, a true friend is something that the words can’t explain. Fortunately, I’ve had luck with my friends, my parents say that I always select good ones. Now, I’ll try to talk about the most important friends in my life.
The first place is for my cousin, Omar. He is 3 years older than me, but always we have been together. We did a lot of antics together, but we did a lot of good things too. I love him and a hope that we can have always a relationship like this. Others of my “family” friends are my brothers, they have put me angry many times, but are more the times that they set me happy. I really can’t imagine my life without one of them, I love them and I know that they love me.
In the school I’ve done a lot of friends. In the kinder I met one of my best friends ever, Marco. He lived three houses next to me and we passed all time together, he came to my home or I went to his house. I really passed good times with him, but sadly he traveled to another place and let me when I was 10; sometimes I miss him. In the middle school I met to Edgar, Daniel, Viri and Diana; every one of them was very different, but unique and special too. I did a lot of things whit them. Was in this stage of my life when I started to go to parties and other places out of home. I still having communication with they, sometimes we go out together and talk about how our lives have been.
When I went to the high school the things changed, but I didn’t be alone for much time, I met very amazing and great people. Every friend that I did have unique and special things and I enjoy them in different kinds, I know that I can trust in everyone. I have friends that make me do things that I wouldn’t do alone, sometimes these things are good but others not at all. I really will miss them, especially to my group, “The Crewtl”. The persons of this group are very special for me, I love every one of them very much. The last years we did a lot of different kind of things, sometimes we went out without planning, we played basketball, when we talk we laugh a lot, we can talk about seriously and sad topics, etc. I think that they are one of the most important things that I will miss when I’ll be at the University, I won’t see them as often as I can do it now. But another stage comes to an end, the life works this way, but I know that we will do all the possible to we can see us sometimes.
The friendship is something that every people must live, is something special and particular thing. I know that I’m this way because the people around me influenced, and I like that those persons were good. I hope that all the persons that I have spoken about in this text feel the same for me. Whatever, always two persons are better than one, and I feel lucky for have more than one.
THE THING MOST IMPORTANT FOR ME... THE MUSIC
Almost all the people love listening to music, but not the same songs. Every people have their own likes and preferences. In this occasion, I will tell you something about my favorite songs of all time and why. First of all, I want to say that I prefer the old time songs but there are many of recently songs that like me too. I’ll show you the songs organized by groups, it will be easier for me. Honestly, I think that anyone will read all this text, but I just want to say how I feel about music and how much it’s important for me.
In the first group I decided to put the songs that inspire me to be better, to take risks, to do more than the people expect for me… to live. All these songs remind me that sometimes doesn’t matter that the things don’t be ok, that they don’t go as I want. Well, I really don’t know what to do in many cases of my life, but it’s ok because the life works this way; I think that the life wouldn't be the same if we know what the destiny has prepared for us. The songs that I putted in this group are Space Oddity, The Anthem, Piano Man, No Easy Way Out, Under Pressure, Artes Paralelas, Quisiera Ser, This Time, Miracle Drug, Ultraviolet (Light My Way) and Window In The Skies.
In the second group I decided to put those songs that always make me feel good, I used to hear them when I’m doing my homework, when I go to school o simply when I’m just feeling ok. All these songs always relax me when I’m stressed or sad. Generally, all kind of songs relax me, but these have something special that make me used to listening when I can. In this list are many old time songs, I love them; I think that this kind of music is the best of all. I selected for the group the next songs: Take Me Home, Caravan, Secrets, Hooked on a Feeling, Old Time Rock & Roll, My Way (A Mi Manera), Whiplash, Just Give Me a Reason, Hold The Line, Little Talks, Losing My Religion, Square Rooms, Down On The Corner and Where The Streets Have No Name.
Finally, in the third list, or group, I decided to put the songs for God, all my favorite songs that praise the Lord. I created this group because I believe in His existence and He is one of my most important things in my life. I always gave him thanks for all his blessings for me and my family; I believe that I’m here because He and I just don’t want to defraud him. In this group I putted these songs: The Anthem, Let It Rain, Save Your Life, Children Of God, Even if, God’s Not Dead (Like A Lion), In The Hands Of God, It Was Finished, Oceans, Listen To The Sound, Love Is War, Me Viniste A Rescatar, Necesitamos De Ti, Never Beyond Repair, One Thing Remains, Rooftops, Tú Harás, We Are Hungry, We Won’t Be Shaken, Tu Mirada, Where I Belong and Weight Of Glory.
The music is something that cannot don't be part of my life, I just love how it makes me feel, this is the only thing that always turns my humor to a good one. I didn’t say it, but the highlighted songs are my favorites of each group; they are like my favorites between my favorites, the very best songs ever (for me). I never wrote about this topic in my life, and I believe that I could write about any other thing. As I said it, I don't think that someone take some of his time for read this text, but I just want to express how important is the music for me.
