2012 is Not the End of the World

Since a few years ago, people have been saying that year 2012 is the end of the world. At 2009, the movie '2012' was released. As a result, many people all the world know about that. I am sure that you know about it too. Then, is 2012 really the end of the world? No, it is not. The scientist have made explanations that are sufficient to prove that 2012 is not the end of the world. Basically, there are 5 theories which says that 2012 is the end of the world. However, scientists have proved that all these theories are not true.

Theory 1: The Mayan Calendar Ends on Year 2012

The Mayan is a civilization in the South America. However, after 600 years, the people of Mayan have disappeared completely. However, they left behind many things. One of the things left behind is a complete calendar that is full of pictures and symbol. Based on the study by the historians, this complete calendar only shows the date until year 2012. As a result, many think that the Mayans have predicted that the world will end on year 2012. However, the scientist Aveni disagrees with this opinion. He thinks that based on the calculation method of the Mayans, 5125 years is the time required for the solar system to complete one revolution. The Mayans calculated the calendar beginning year 3114 B.C. So, instead of being the end of the  world, 2012 should be seen as a new year.

Theory 2: The Solar System Falls into the Center of the Milky Way Galaxy

On the year 2012, the whole solar system will be in the center of the Milky Way Galaxy. This will happen only every 26000 years. 26000 years ago,  humans have not yet fully developed, in fact they do not know what is Earth. Some people think that if the Sun falls into the center of the Milky Way Galaxy, it will cause serious and unpredictable effects on the Earth. It may cause the poles of Earth to shift, or even cause the Earth to be attracted into the Black hole. However, the scientist Morrison advice us not to worry. In his opinion, such thing will not happen on 2012. In fact, a similar phenomenon can be observed during the Winter Solstice of every year. During that time, the Sun appears to be in the center of the Milky Way Galaxy. However, it does not cause any negative effects on Earth. The Earth's gravity, the Sun's radiation, the planet's orbit and other things are all not affected.

Theory 3: The Collision with other Planet

All the while, people are always worried of the collision between the Earth and other planet. Although at all times, there are a lot of meteoroids from other space colliding on Earth, but luckily, they are all very small. Therefore, before the meteoroids reach the earth's surface, they are burnt in the Earth's atmosphere, so when they land on Earth, they are too small to cause any damage. Thanks to the atmosphere! Some people predict, a very large planet known as Nibiru will collide on Earth on year 2012. Even if it only goes near the Earth, it can cause very great damage, causing the Earth to move out of its orbit. Actually, people are worried all because a woman in USA claimed that she had received an e-mail from aliens which gives warning to humans. Based on the opinion of the scientist Morrison, he is sure that nothing will collide on Earth on year 2012. This is because if any planet goes near the Solar System, we will be able to see it 3 years earlier, but nothing have been observed until now. In addition, if there is a planet large enough to destroy the Earth, we can see it long before it collides on Earth.

Theory 4: The Predictions by the Mayans

The question is, if the Mayans have known that the world will end on year 2012, why there are no pictures which clearly says what will happen? Many historians said that after researching for many years, they have not yet found any clear predictions regarding year 2012. On the last page of the book left behind by the Mayans, there are statements that the Earth will suffer damage from heavy floods. Similar statements are also found in the legends of other races. The scientist Aveni believe, based on the Mayan's culture, this statement is not a prediction, instead, it is actually symbolizing the punishment for the human's actions . The human's actions have caused pollution and many other environmental problems. Since 2012 is a new year for the Mayans (as stated earlier), the Mayans want humans to learn from their mistakes and have a new beginning.

Theory 5: The shifting of the Earth's poles

The Earth's poles is the two ends of the Earth axis. They are located in the North Pole and South Pole. If the  Earth's poles shift position, there will be many great problems. The Earth's crust may move violently and the land of the seven continents may crack, just like an earthquake with magnitude 10. If an earthquake with magnitude 10 occurs, the whole Malaysia can be destroyed in just 10 minutes. If the crust of the whole Earth shifts at the same time, it can cause earthquakes, tsunamis, volcanoes and other natural disasters. The damages caused will be unpredictable. But we should not worry. Based on the opinion of the scientist Adam Maloof, even though the Earth's crust is currently shifting, but the process is so slow that it takes several million years before it can cause any damage.

After reading this, you should know that year 2012 is not the end of the world. So, don't worry about it. Instead, we should protect the environment so that the Earth can live longer.

Computer Learning

Now, using the computer and surfing the internet is one of my hobby. I am also very good in computers. But do you know when and how I started to learn how to use a computer?

I started using computer when I was 3 years old. At that time, I went to my father's house in Subang Jaya, Selangor. There is a computer in his house. That is a HP Desktop computer with Windows 3.1 . It was actually an old computer. I liked to play with it very much. Therefore, my father brought it back to Kulim for me.

At first, I don't know how to use a computer correctly. I played a few games but I just simply play because I don't even know how to play it so I always lost. Later, my parents tought me how to play the games, then I began to know how to play. Besides playing games, I didn't know anything else about computers. The games were only very simple games.

Then when my brother knew how to play computer, he always play with my computer when he came back to Kulim. This is because there were no computer at his house. Several times I fought with him just because of the computer. At the year 2002, he wants to bring my computer to his house. I tried to stop him. My father told him to give that computer to my brother and promised to buy me a new one. The new computer I have is installed with Windows XP and I used it until now. Now it is already 8 years but still working!

When I started using this computer, I only use it to play games. The games were much newer and more advanced that the old computer. My father also installed TM Net internet service at my house for me. I knew very little about computer at that time. I only used the internet to download games. However, the internet was very slow and most downloaded games have a trial. At that time I never knew how to crack and my mother only purchased one game for me. Sometimes my mother downloaded the games using Streamyx and wrote them into a CD for me to install.

However, later I moved house. In the new house it is very troublesome to use the internet because I had to connect the wire over the living room floor. At the year 2006, I read a comic. Behind the comic are computer teachings. On that year also, my computer got infected by virus. I tried many antiviruses to remove the virus but at last I failed. I had to send my computer for repair. But, I began to know more about computers. I began to be less-interested in computer games. I prefer to download and use different types of softwares.

In Form 1 and 2, I had the chance to use the computer and internet in school every week during the ICT class. I began to use the internet widely. I also signed up for Friendster, Tagged, Facebook and much more. But it is difficult for me to use the internet at home. The TM Net is very slow and I had to connect the long cable over the floor. Once somebody fell down because of the wire. My father had a Maxis Broadband but I could use it only when he comes back to Kulim. My phone could surf the internet but it is very expensive.

Finally, at the end of year 2009, my father signed up another Maxis Broadband for me so that I can use the internet easily. In order for the Maxis Broadband to function properly, I moved my computer upstairs and reformatted it. I could use the internet whenever I want. I also know a lot about computer now. I also upgraded from Windows XP to Windows 7. But because of my PMR examination, I don't use the computer or go online too often.

After my PMR examination, I played computer very often for more then 2 months until the 2010 year-end school holiday is over. I went to Kuala Lumpur for holidays on December 2010. My parents bought me a new Acer laptop on 9 December 2010. It has Windows 7 Home Premium, Intel Core i5 CPU, 4GB RAM and ATI 512MB Graphics Card. It is very fast and good. However, the Maxis Broadband internet was very slow when I used it on the Acer Laptop. On 14 December 2010, my father took me to the Maxis store and replaced my Maxis Broadband modem. After that, the internet could work very fast. I concluded that the old Maxis Broadband modem was not compatible with Windows 7. Since then, I usually used the new Acer Laptop rather than my old Packard Bell desktop. I only used the Packard Bell desktop for testing purposes. On January 2011, the Acer laptop had a problem. The problem started after I attempted to install Microsoft Office. I tried to repair it but I failed. My mother took it back to Kuala Lumpur for repair. It was successfully repaired and I used it until now.

When I entered Form 4, I took the Information and Communications Technology (ICT) subject. The reason is it is easy and interesting. After I took ICT, I could learn more about computers. I was interested in ICT and could score well in it. In the 1st, 2nd and 3rd school exams, I got 96 marks for ICT. In the 4th school exam, I successfully got 100 marks for ICT. I could also complete most of the coursework for ICT. At the end of Form 4, all students are asked to choose the subjects for SPM. Some students decided to drop ICT because no one got A+ in ICT for SPM 2010. But, I took ICT because I was confident that I could score A+ as long as I worked hard for it. After entering Form 5, I continued to take ICT and I registered it as a SPM subject. In the 1st exam, I got 97 marks. In the 2nd exam, I got 100 marks. For the SPM Trial exam, I got 99 marks. For the actual SPM exam, I got grade A+.

After my SPM examination, I played computer and surfed the internet almost every day. I upgraded my Acer laptop from Windows 7 to Windows 8. Initially, I planned to dual-boot Windows 7 and Windows 8 on my computer. The upgrade was successful and I liked Windows 8 because it was fast. However, due to some mistakes while partitioning the hard disk during the installation, I had to delete Windows 7 and all the files stored in the hard disk. I had to recover all the files and programs on my computer manually. Although Windows 8 is good, I still missed Windows 7 so later I installed Windows 7 on VMWare Player on my Acer laptop.
