News

      Every morning my mother starts her day with news from around the world. For me , I'm not intrested in that because i don't trust midia . From my opinion each newspeper or news channel has espical agenda which try to cnvince people to believe in what they believe in. However, to follow the news and be objective you have to be fimieler with the world  history. Although , not all history books are so objective . It's realy hard to find some worthtrust news these days with all these wars and violince around the world .
     Censorship is onther problem . In Arbic countries the news is censored by goverments and people used to search in diffrent websites to find out what realy going on . These day, Twiter has been the number one websiet which people trust to get news because people can see what ever they wants and shere news together .

Alhazen and Galileo Galilei

Alhazen and Galileo Galilei     

         
      100 years ago people did not know as much as we do these days. What about 1000 years ago? At that time people were thinking that the Earth is the center of the world and the sun moves around it . Until  Alhazen invented optics science  and Galileo used it to  prove that was not true .  Despite the fact that Alhazen and Galileo had  similarities , they also had some differences.

         According to psychologists the backgrund is a mean factor in any personalty. In the same way , Alhazen was born  in Basra in 956, which known as Islamic golden age. He was educated in Bagdad, after that he moved to Cairo and worked there as civil servant. Next he wrote his book "Book of optics" .Also he tough at Alazhar  university . However, Galileo Galilei was born  in 1564 ,in Pisa .He was educated in the Camaldolese Monastery at Vallombrosa , southeast of Florence. In 1581 he diced to change his major from medicine to mathematics and nature philosophy.  Then he had been tough at University of Padua until 1610 .  

        Galileo was interested in  Astronomy , but Alhazen was not interested in that field  . Actually ,Alhazen spent his live studying optics science. they both were the most intillegnt scientists in their field . In fact without ALhazen book ,Galileo would not be abel to prove his ideas about Astronomy . Because the telescope  which Galileo had been used it besad on Alhazen book. 
     
       Similarly, Alhazen and Galileo fought false beliefs . In Alhazen case , people thought the light comes from eyes to things and that way people could see. Alhazen did not believe that and he searched and did experiments in animals eyes  until he found that eyes receive lights, then  reflect it outside and that why we can see .   Although , in Galileo time, people believed that the earth is the center of the world and the sun moves around it. As alhazen , Galileo made his research ,and by his telescope he saw that many planets have more than one moon move around them , and they all include the earth move around the sun.
      
       After what I found about  ALhazen and Galileo, I realized  that they put the corner ston in Astronomy and optics science. After that many scientists  have been used them in all possible areas. Although , after 100 years, people will know more and more than what we know now. 
      
     

talented people

     Some people might disagree with me in that but from my opinin everyone is talented in some how . However , not all of them discover their talent . As i read from books, kids are more talented and if there parents didn't find their kid's talent in early 5 years, the kid may lose his talent and live as normal person for the rest of his life .
    

Using animals in disease research

Using animals in disease research 

        Aristotle in the fourth century started using animals in experiments to compare between animals and human's body. Therefore in 1859 Darwin's theory strengthened Aristotle experiments ,and since that animals have been used in research. However, people still debating whether it is necessary to use animals in research or not . The three following  reasons show why using animals in disease research is necessary .

     First, animals are not different from humans, they share a lot of similarities . Mice for example have the same organs as humans , in the same place and doing the same jab. Which make them affected by the same factors. So scientistes try the drugs in laboratory animals first before using it in humans.

      Second, using animals in disease research is the most important part to develop any medicine , and to finde out their possibility of treating disease .It is necessary to try the drugs before giving them to the patent to see if there any side effect or complication .

    Finally,  Other research methods are ineffective . Scientists tried to use different ways to avoid using animals in research ,like computer models. Yet these methods didn't give the same result  to the druges as human's body did, and this may put someone life in real jeopardy .

     On the other side , some people says there are some field experiments for drugs was safety tested in animals and had a negative impact in humans. But this is a one of thousand testes worked perfectly in humans. Others might say using animals in research is against humanity.Actually , sacrificeing animals to save people lives is a part of our humanity. 
 
     Since time immemorial humans use animals to help them in several areas.  Also millions of people  get benefit from medications have been tested in animals. The question becomes: without animals research, can medicine be as effective as we see it today?

Euthanasia

     Euthanasia or mercy killer is a thorny issue. Suffering from pain needs faith and power to handle it, and not everyone could do that. That why Euthanasia has been existed .
     People have different opinions about this subject .  It is hard for any one to see the one who loves suffering , even though choose mercy killer is harder. people who agree with euthanasia try to releve the patent from his pain and think this is the better for them . On the other hand people who disagree with it think killing the patent is take his live unjustly
   form my point of view Death is God's decision.The one who gives the live is the one who has the right to takes it. killing someone is ending their live even if they ask for it. their pain and frustration prevent them from thinking in the right way. 
     Finally, each situation has different circumstances which control the feeling at that moment . Although everyone thinks s/he does the best for their lovers .
