Nova Science Now: Asteroid

The asteroid might hit Earth in 2029! What a terrible thing!
After watching this video, I have many different kinds of feeling. Firstly, it is an interest because of the information about our solar system and especially about asteroid in this presentation which I never knew before.It made me surprised. Also, it stirred the curiousness in my mind. I thought our universe has full of mysteries like asteroids, galaxy, black holes which not only meself but also most people in the world would like to discover. However, there is sadness because I felt that the Earth and human are tiny in this immense universe. So, what can we do to safe the earthand our lives? Using our brain and all knowledge to prevent it. The scientists also show us 2 methods to protect our plane. The first one is using nuclear weapons to deflect the asteroid's orbit or making them slow enough to miss the earth. The second methods is use a gravity machine to deflect it out of the earth. That sounds good, but just a few people people agree with it. I hope the scientists can succeed to prevent an asteriod.

This is the first assignment which is not listening on blog.

After looking at some information about American population at website http://www.census.gov
we can infer that US will be many more elderly in the future than now. Why could I say that?

The data are drawn primarily from many different sources. Data discribing the overall population by age and sex (such as percentage elderly and support ratios) refer to the entire population; data for specific population characteristics such as education, labor force participation, poverty, foreign-born status, and living arrangements refer to the civilian population.
Current Population Survey estimate for the early 1990s are inflated to national population controls by age, sex, race, and Hispanic origin.
We know there will be many more elderly in the future than now, but projections differ in predicting how many more. These differ in terms of the assumptions concerning the future trajectories of fertility, mortality, and net migration.

hi

Introduce myself ! , I don't know what I should tell you about myself now. I did it many times and as a result, now...nothing shares you.
Anyway I had to do unless my scores would be lost.
" hi, My name is Anh. I'm from Vietnam. I've been Seattle for 4 months. Before being here, I studied English in RMIT, an Australian university. My purpose is studying in UCLA so I have to study harder and harder.
Do you think I'm studious? hahaha. At the first look, most people think that I'm hard working, but they're wrong. I'm exactly a lazy student. I always study and do my homework before the deadline few hours. I tried to overcome that defect but it's hard to do.
I love to travel. to encourage me, my mom allow me to travel one country I had a good result every school year .

Here something about my family. Family are the most important thing in my life.
