Leonardo da Vinci was born on April 15, 1452 in Italy. He is best known as an artist today. One of his famous paintings is called Mona Lisa. However, Leonardo had many other natural abilities. He was also a great inventor. Many of his inventions have become important in modern day life.
Although Leonardo hated war, he invented many different machines used for war. His most special invention was the machine gun, which was produced and used in war many years later.
By watching the way birds fly，Leonardo tried to find out the secret of flying. Among his sketches(素描)we can see several objects. We consider them as modern flying machines.
Leonardo spent many hours thinking about how to make good use of time. He developed ideas for labor-saving machines like cutting machines.
Leonardo was a strange man. He didn’t eat any meat，which was very unusual in those times. He never published (发表） his ideas and scientific discoveries. He usually used mirror writing，which looks like writing in a mirror, starting from the right side of the page and moving to the left.
We have very little of his work today. Leonardo finished only a few of his paintings. He left many unfinished because he thought they were not perfect. No one in his life time knew how great Leonardo was. We now believe，however，that he was one of the cleverest men the world has ever known.

An American named Crum invented potato chips in 1853, although that was not his intention (意图）. He was a chef(厨师长） at a beautiful restaurant in Saratoga Springs, New York. A regular dish on the menu was fried （油炸的） potatoes, which was an idea that had started in France. At that time, French fried potatoes were cut into thick slices (片）.
One day, a dinner guest at the restaurant sent back his fried potatoes to the chef because he did not like them so thick. So Mr. Crum cut the potatoes a little thinner and fried them. The guest did not like those either. That made Mr. Crum angry, so he thought he would just show the man. He sliced the potatoes paper-thin and fried them, thinking that the man would say nothing about it. However, to his surprise, the man loved the thin potatoes very much. Other guests tried them and also liked them. So, Mr. Crum’s potato chips were added to the menu. They were called Saratoga Chips.
Finally, Mr. Crum opened his own restaurant to sell his famous chips. Now potato chips are packaged (包装） and sold in stores.
