功能
Roger Sperry and Robert Ornstein of the California Institute of Technology, Nobel Prize winners, discovered that the human brain has two sides, and each side has different work to do.
The left side of the brain controls language and arithmetic(算术) and it analyses and reasons. __1___ It controls our appreciation of music and our sense of rhythm. It is also the right side of our brain that daydreams.
Leonardo da Vinci was a great painter and sculptor. He was also an architect, an engineer and an inventor! ___2__ When he invented machines, he used both his imaginative ability and his analytical ability.
__3___ Albert Einstein enjoyed art, playing the violin and sailing. Indeed, Einstein said his scientific discoveries grew from his imagination rather than from analysis, reason and language. He said that written and spoken words were not important in his thinking. The story goes that Einstein was daydreaming one summer's day while sitting on a hill. He imagined that he was riding on sunbeams to the far distance of the universe. Then he found that he had returned to the sun. So he realized that the universe must be curved(弯曲的). __4___ He then used the left side of his brain to apply analysis, arithmetic and reason. And finally he used language to explain it.
Traditional education in schools encourages us to use the left side of our brains. Language, arithmetic, analysis and reason are given more importance in our schools than imagination and daydreaming. Why don't we give more value to visual thinking Why jump on one foot if we have two perfectly good legs!
__5___ We need to use our imagination to think of solutions to problems and to ennal and artistic experiences. And we need to be logical and to be able to analyze and organize in order to survive day by day.
