¡°Dear Sir, I probably would have written ages ago, only I was not aware(Òâʶµ½)that you were still alive, ¡±writes a South African schoolgirl called Tyfanny in 1946. ¡°I must have been mixing you up with Sir Isaac Newton. ¡±

Tyfanny, who goes on to ask Albert Einstein about the nature of space, received a(n)  1  reply from the great man six weeks later. ¡°Dear Tyfanny, ¡±he writes, ¡°I have to apologize to you that I am still among the  2  . This will not always be the case, however. ¡±

Tyfanny is one of the 60 children whose   3  to one of the greatest scientists of all time are  4  in the book Dear Professor Einstein: Albert Einstein¡¯s Letters To And From Children.

The letters are printed  5  as they were written, spelling  6  and all, with some printed in their original handwritten form.

While many letters seek answers to  7  questions, such as ¡°what  8  the sun and planets in space?¡±or ¡°I want to know what is beyond the sky and my mother said you can tell me, ¡±others are more personal. ¡°I would like to ask if you   9  make any mistakes. ¡±  10  one child. While the children¡¯s letters are certainly entertaining,   11  is Einstein¡¯s replies that attract the most interest.

  12  , he could not respond to every letter, but the letters he did  13  the time to answer, which showed the human side of the great scientist. Although he   14  his days looking into mathematics and   15  , he was always very fond of children and their boundless curiosity(ºÃÆæÐÄ).

For example, it was in a letter to a 12-year-old girl from New York that he makes his now well-known remark:¡°Do not worry about your  16  in mathematics; I promise you that  17  are still greater. ¡±

¡°This is a beautiful and touching  18  . It is amazing how intelligent some of the children¡¯s  19  are, ¡±said a reader from Georgia, US. ¡°but it is more interesting to get to know the other  20  of Einstein. ¡±

It is natural that children are curious (ºÃÆæµÄ) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
¡¡¡¡As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (ÉúÑÄ¡¢Ö°Òµ) in science.
¡¡¡¡Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
¡¡¡¡These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (±Ã) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
¡¡¡¡Of course, scientists cannot answer all of our questions. If we ask, ¡°Why does the ocean water taste salty¡± scientists will say that the salt comes from rocks.
