People often ask me if I know the secret of success, and if I could tell others how to make their dreams come true.My answer is, you do it by working.

One of the longest outstanding mysteries in physics is how gravity is related to the other fundamental forces, such as electromagnetism.

In that way, we can do some research about the water to solve the mystery.

But this does not do justice to this city of two cultures, which hides plenty of interesting secrets.

And the secret was excess: the tallest buildings, the artificial islands and so on.
