Chemistry PLN3

I found the news from website of Boston University.

BUYCC, the abbreviation of Boston University Younger Chmistry Committee.http://chemweb.bu.edu/buycc/
   This is the eassy I found on the website introduces the Chemistry Committee in Boston University which attracts me,since my major in college is chemistry. I exactly want to go to a shcool which think highly of chemistry. As far as I concern, Boston University is one of the schools that suits my standard. It describes how many people or professor in the Chemistry Committee and tells me they also think chemistry is one of the major all over the world.
   I agree that chemistry must be one of the most significent science we need to pay attention to.


   Besides, I also find another interesting blog which link is http://prospect.rsc.org/blogs/cw/2013/02/04/quantum-chemistry-takes-on-virtual-reality/
   The essay's name is Quantum chemistry takes on virtual reality.
It is the eassy talks about the relationship between computer games nowadays and the quantum chemical calculations and reactions. Using some specific ways to make the calculation be easier and quick.As the articles says" chemistry can feed off the resource-hungry world of video games to provide the hardware and computational power", which means chemistry can lead the world be more creative and fundamental.
   I believe, using chemistry appropriatly and efficiently, the world will be better.

Comment for "Truth And Beauty In Chemistry"

  I just read a book about chemistry named "Truth and Beauty in Chemistry", which talks about the difference between basic psysics and math. Of course, they have their own beauties. However, as the wirter says, the beauty of chemistry is most fantastic and interesting.
  Here is one example to tell why the wirter thinks chemistry is beautiful. All of the material in the picture are composed by four elments- carbon, hydrogen,nitrogen and oxygen. But the different sequences make them become different compounds. Its beauty appaars with its varieties.
  During the process of the reaction, the reactant will disappear and transform into another material. Such as the reaction that carbon is burn in the oxygen, they will generate carbon dioxide.
of course, this procedure is not beautiful. For another one, such as copper sulfate. When it contacts with water, it will be blue from white.
  It is beautiful, isn't it?
  As for its truth, people can just learn about every specific process when they familiar with the sequences of the material and the equation about the reaction.

My Favorite: Chemistry

     Chemistry, a branch of physical science, is the study of the composition, properties and behavior of matter. It is interesting for me since it just looks like magic in some aspects, for which they products or make very different material behind amazing reactions.

     Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds. It is also concerned with the interactions between atoms (or groups of atoms) and various forms of energy. Every item exist contains this or that lots of different atoms or molecules. They make up the life and wrold. So, the deeper human want to find the basic, chemistry have a more important status.

    Besides, it is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other. So, I love it, for its fantasy and his comprehensiveness. Every time we mix different items into a beaker, they material may convert to another one and may have a bright-color.

    The etymology of the word chemistry has been much disputed. The genesis of chemistry can be traced to certain practices, known as alchemy, which had been practiced for several millennia in various parts of the world, particularly the Middle East.
 As for me, my major in college will be chemistry, when I can spend more and more time on the experiments and find the interesting reaction principles.

O Captain My Captain

              O Captain, My Captain.
                                               written by Walt Whitman


O Captain my Captain! our fearful trip is done,
The ship has weathered every rack, the prize we sought is won,
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring;
But O heart! heart! heart!
O the bleeding drops of red,
Where on the deck my Captain lies,
Fallen cold and dead.
O Captain! my Captain! rise up and hear the bells;
Rise up--for you the flag is flung for you the bugle trills,
For you bouquets and ribboned wreaths for you the shores a-crowding,
For you they call, the swaying mass, their eager faces turning;
Here Captain! dear father!
This arm beneath your head!
It is some dream that on the deck,
You've fallen cold and dead.
My Captain does not answer, his lips are pale and still;
My father does not feel my arm, he has no pulse nor will;
The ship is anchored safe and sound, its voyage closed and done;
From fearful trip the victor ship comes in with object won;
Exult O shores, and ring O bells!
But I, with mournful tread,
Walk the deck my Captain lies,
Fallen cold and dead.



    It is the most fantasy and magic poem for president Lincoln, which is also was most impressive and popular poem at that time. Of course, it talks about a captain who is brave and help his ship get rid of risks and danger. As far as I think, the image I found from Internet is very suitful and appropriate. In it, the captain holding the sword, lifting the eagle, stands infront of the sea within roaring waves.

   He, The captain,who found the new lands for all members on the ship,died, left the cold and dead body. His eyes would not open, his heart would not beat, any more, no more. He died." But I, with mournful tread, Walk the deck my Captain lies, Fallen cold and dead ". 
    How sad it is! He devoted his life and future to dirct others find the better future, but the consequnce he got, is death. He is a hero. President Lincoln, as the captain, was a hero in a great number of peoples' hearts. Although I am not an American, I can still imagine how people admire their captain, the hero, president Lincoln.
    

Nature Poem

                                    When I first see the poem with a picture, I fall in love with it.

When I was a very young child, I was curious about it.

Is it fly? Of course not.

So ,I think about it.

Now,still.

When I see this poem, I have a new feeling. Sometimes we can link the spider have some commons as people have. As for, sometimes I am a spider as it too.

We never have a long break to have a rest. In china, there is byword: it is never to old to learn. So, we are always running on the road to knowledge.

My favorite lines are when the author says, "Surrounded, surrounded, in measureless oceans of space".

For human, the world is big and almost people can not travel all over the world. As for a spider, a garden is amazingly big and it will be very difficult for them to connect its net and find the feasible path. A spider must be lonely, it may be the only one in his area. However, it will not stop and give up. The only thing spiders will do just work harder. I'm not sure if my thoughts were correct but thats just the first image that popped into my mind when i read it.  

What I Carry

Every day, the things I must carry:

My school id

Two cell phones: Chinese and USA cell phones.
Glasses.
And several textbooks,whose names are:
The Things They Carried
Myers's Psychology For AP
Chemistry the central science.

School ID:
It is one of the most important items which decides if I can have food for lunch. If I leave my school id in dorm, I will be upset that I will not have anything to eat during lunch and see others eating happily. Unfortunately, because of its small size, I ignore it few times a week. Each time I forget it, I tell myself: My lunch, my delicious lunch, I miss you!

My cell phones. The Chinese one is used to send messages to my girl friend and it is the only function it has. Sending messeage is the most common way for us to communicate, since the calling is not allowed in school and the fee is expensive.
As for my USA cell phone, it is excatly useless.

Glasses, I wear every day beacuse my myopia. Without my glasses, I can hardly see anything, so that the efficiency for every course I have will be as low as I do not understand.

  Last but not least, Textbook, such as The Things They Carried, is the book we are reading for English IV. I just made a mistake and lost 10 points since I left the book in the dormitory. Although I told myself I needed to bring it, I still forgot to carry. 

My holiday

  As for my winter break, I came back to China and go to a small city which is called Yiwu. The first famous items for the city is smallware, it is international and is accepted all over the world. So, it is a international city in few peoples' eyes. But excatly, when I was there for visting the girl I love but who does not love me, I change my mind. It is developed but still keep the vallge style soemwhere.
  For urban area, the buildings and atmosphere are same as they are in Shanghai which has been an international city for about 30 years. However, when we went out the city to some rural area, we can find the different lifestyle we can only find in some orignial village.
  It is not the most important significent event happened during the period I lived in this city. She became my girl friend! It is one that I dreamed for a long time. When she agreed to give me the identity of her boy friend, I felt it was unreal.Was I dreaming?  But I realize It is true. It was not a fantasy. So the trip I went to the international city is very impressive and very importent to me.
