Watch a baby between six and nine
months old, and you will observe the basic concept of geometry being learned.
Once the baby has mastered the idea that space is three dimensional, itreaches
out and begins grasping various kinds of objects. It is then, from perhaps
nine to fifteen months, that the concepts of sets and numbers are formed. So
far, so good. But now an ominous development takes place. The nerve fibers in
the brain insulate themselves in such a way that the baby begins to hear sounds
very precisely. Soon it picks up language, and it is then brought into direct
communication with adults. From this point on, it is usually downhill all the
way for mathematics, because the child now becomes exposed to all the nonsense
words and beliefs of the community into which it has been so unfortunate as to
have been born. Nature, havin A. Picking up a wooden block B. Recognizing the number C. Uttering a nonsense word D. Looking at distant object [判断题]《中华人民共和国特种设备安全法》明确,为了加强特种设备安全工作,预防特种设备事故,保障人身和财产安全,促进经济社会发展,制订本法。( )
