Book review

1. He likes to think:He liked to read and think. He would lie on his back on the grass，look at the sky，and think about space. Sometimes he had crazy ideas. If people could turn off gravity，what would the world look like？What if people could ride on a beam of light？It was as if Einstein were born to think. 2. He is diligent:“It's not that I'm so smart；it's just that I stay with problems longer，” he told the world.
