曾经有个脑筋急转弯:把大象放进冰箱,总共分几步?第一步,打开冰箱门;第二步,把大象放进冰箱;第三步,关上冰箱门。一共三步!这一次,清华大学的科普专家高老师提出的问题是:用弹簧秤称大象,可以分几步?并为此组织了一场超酷的现场竞技——用弹簧秤称出大象的重量,看谁的方法更为便捷、巧妙。比赛规定使用的弹簧秤最多只能称5千克的东西,怎么能称出几吨重的大象呢?让我们去比赛现场看看吧! Once there was a brain teaser: the elephant into the refrigerator, a total of several steps? The first step, open the refrigerator door; The second step, the elephant into the refrigerator; The third step, close the refrigerator door. A total of three steps! This time, Tsinghua University science expert Gao teacher raised the question is: the use of spring scales that elephants, can be divided into several steps? And organized a cool on-the-spot competition - weigh scales with a spring balance The weight to see who the method is more convenient and clever. Competition rules using the spring scale can only weigh up to 5 kilograms of things, how can weigh out a few tons of elephants? Let’s go to the game site to see it!
