¡¡¡¡A successful scientist is generally a good observer£®He makes full ¡¡¡¡1¡¡¡¡ of the facts he observes£®He doesn't accept ideas which are not ¡¡¡¡2¡¡¡¡ on obvious facts, and therefore refuses to accept authority(ȨÍþ)as the only ¡¡¡¡3¡¡¡¡ for truth£®He always ¡¡¡¡4¡¡¡¡ ideas carefully and makes experiments to prove them£®

¡¡¡¡The rise of ¡¡¡¡5¡¡¡¡ science may be considered to ¡¡¡¡6¡¡¡¡ as far back as the ¡¡¡¡7¡¡¡¡ of Roger Bacon, the wonderful philosopher(ÕÜѧ¼Ò)of Oxford, who lived ¡¡¡¡8¡¡¡¡ the years 1214 and 1292£®He was probably the first in the middle ¡¡¡¡9¡¡¡¡ to suggest that we must learn science ¡¡¡¡10¡¡¡¡ observing and experimenting on the things around us, and he himself ¡¡¡¡11¡¡¡¡ many important discoveries£®

¡¡¡¡Galileo, however, who lived more than 300 years later, was the greatest of several great man, ¡¡¡¡12¡¡¡¡ in Italy, France, Germany, or England, began by ¡¡¡¡13¡¡¡¡ to show how many important ¡¡¡¡14¡¡¡¡ could be discovered by observation£®Before Galileo, learned men believed that large bodies fell more ¡¡¡¡15¡¡¡¡ towards the earth than small ones, ¡¡¡¡16¡¡¡¡ Aristotle said so£®But Galileo, going to the ¡¡¡¡17¡¡¡¡ of the learning Tower of Pisa, let fall two ¡¡¡¡18¡¡¡¡ stones and proved Aristotle was wrong£®It was Galileo's ¡¡¡¡19¡¡¡¡ of going direct to Nature, and proving our ¡¡¡¡20¡¡¡¡ and theories by experiment, that has led to all the discoveries of modern science£®

Number¡¡ sense is not the ability to count. It is the ability to recognize a ¡¡ 1¡¡ in number. Human beings are born with this ability. 2 £¬experiments show that many animals are, too. For example, many birds have good number sense. If a nest has four eggs and you remove one, the bird will not¡¡ 3 . However, if you remove two, the bird 4 leaves. This means that the bird knows the ¡¡5¡¡ between two and three.

Another interesting experiment showed a bird's 6 number sense. A man was trying to take a photo of a crow(ÎÚÑ»)that had a nest in a tower, but the crow always left when she saw him coming. The bird did not 7 until the man left the tower. The man had an 8 .He took another man with him to the tower. One man left and the other stayed, but they did not 9 the bird. The crow stayed away until the second man left, too. The experiment was¡¡ 10 with three men and then with four men. But the crow did not return to the nest until all the men were 11 .It was not until five men went into the tower and only four left that they were 12 able to fool the crow.

How good is a human's number sense? It's not very good. For example, babies about fourteen months old almost always notice if something is taken away from a ¡¡13 group. But when the number goes beyond three or four, the children are 14¡¡ fooled.

It seems that number sense is something we have in common with many animals in this world, and that our human 15 is not much better than a crow's.

¡¡ Mentors teach things that seem to be ¡¡6¡¡ sense. Proverbs are wise old sayings that are common in every language and¡¡ 7¡¡ , and can sometimes be¡¡ 8 for a nonnative to understand. For example, all that¡¡ 9¡¡ is not gold(some things are not as ¡¡¡¡10 as they appear ).
