Cormorants recover in a Saudi pool after the first gulf war. Iraqis retreating from Kuwait damaged nearly 800 oil wells, poisoning 300 miles (483 kilometers) of coast and 600 square miles (966 square kilometers) of the Persian Gulf, including the breeding grounds of sea-faring cormorants and grebes. Six months after the destruction, coastlines were still black and desolate, proving that recovery would be slow for the fragile ecosystem.

你相信数学魔术吗？(Do you believe in mathemagic?)6Vu中国英语学习网

Everyone knows what a magician is, but what about a "mathemagician"? The truth is, math and magic have been partners for so long that they are like best friends who finish each other's sentences! "Mathemagic" is simply using math to perform magic tricks. You can use the basic laws of geometry to create an illusion, and number rules can help you amaze your friends by revealing "secret" numbers during a mind-reading act.

Ancient mathematicians such as Euclid, who is called the father of geometry, and Pythagoras, who is best known for a famous geometric principle called the Pythagorean theorem, also were viewed as magicians. Ancient magicians were also astrologers and fortunetellers, but today's magicians are mostly entertainers.

Magic based on mathematics is fun and easy because once you know the secret behind the trick, the trick works all by itself, just as a math problem does.

Want to try? Here's how.

Calculational wizardry Write the number 1,089 on a piece of paper, and put it in your pocket. Tell a friend you can predict the answer to a series of math problems that uses any number your friend chooses. Ask your friend to come up with any three-digit number containing all different digits. Then, reverse that number. For instance, if your friend chooses 647, reverse it to 746. Now subtract the smaller number from the larger one, in this case subtracting 647 from 746. If the answer is less than 100, put a zero in front of the number to keep it three digits. The answer in this example is 99, or 099 after you add the zero. Now reverse the number again (making it 990) and add it to 099. The answer is 1,089! Take the piece of paper out of your pocket and show your prediction to your friend.

How it works: Look closely at the three-digit number you get when you subtract the smaller number from the larger one. The middle digit will always be nine, and the outer digits will always add up to nine. The same is true when you reverse that number. Therefore, when added together, the last row will always equal 9, the middle row will always equal 18, and the first row will always equal 10 (carry the 1!). So the answer will always be 1,089.

You and Me：Lifehouse 深情唱我们

歌词：

You and Me Lifehouse
What day is it
And in what month
This clock never seemed so alive
I can't keep up
And I can't back down
I've been losing
So much time

Cause it's you and me
And all of the people
With nothing to do
Nothing to lose
And it's you and me
And all of the people
And I don't know why
I can't keep my eyes off of you

All of the things
That I want to say
Just aren't coming out right
I'm tripping on words
You got my head spinning
I don't know where to go from here

Cause it's you and me
And all of the people
With nothing to do
Nothing to prove
And it's you and me
And all of the people
And I don't know why
I can't keep my eyes off of you

Something about you now
I can't quite figure out
Everything she does is beautiful
Everything she does is right

Cause it's you and me
And all of the people
With nothing to do
Nothing to lose
And it's you and me
And all of the people
And I don't know why
I can't keep my eyes off of

You and me
And all of the people
With nothing to do
Nothing to prove
And it's You and me
And all of the people
And I don't know why
I can't keep my eyes off of you

What day is it
And in what month
This clock never seemed so alive
