첫댓글The book's title is "An Apple, An Idea." The main character is Sir Isaac Newton. One summer day, as Isaac Newton sat under an apple tree, an apple fell down and struck his head. He wondered why the apple fell down instead of up. It was a long time before he could answer this question. Today, his answer is called the law of universal gravitation. The Earth we live on is much bigger and heavier than the things on it. That's why everything falls to the ground. The big, heavy Earth pulls the lighter things down with a force called gravity. Gravity holds the whole universe together.

The main character is Sir Isaac Newton. One summer day, as Isaac Newton sat under an apple tree, an apple fell down and struck his head. He wondered why the apple fell down instead of up. It was a long time before he could answer this question. Today, his answer is called the law of universal gravitation.
The Earth we live on is much bigger and heavier than the things on it. That's why everything falls to the ground. The big, heavy Earth pulls the lighter things down with a force called gravity. Gravity holds the whole universe together.
I think Isaac Newton was a genius.
