曾经有人向诺贝尔奖获得者、著名物理学家布洛赫求教一道题,题意大致如下:水池中有一条船,船上装有石头,如果把船上的石头投入水中,水池内的水位将如何变化?这位物理学家立刻判断水位会上升,因为他觉得船中的石头投入水中后,池水会因为石头占去一定体积而“膨胀”。田田和他的同学们看到这个故事后,也产生了极大兴趣。那事实究竟是怎样的呢?物理是门以实验为基础的学科,因此大家决定用大烧杯模拟水池、小烧杯模拟小船,亲自动手实验来说明
Someone once asked the Nobel laureate, a famous physicist Bloch, for the following questions: The boat has a boat and the boat is filled with stones. If the stones in the boat are thrown into the water, how will the water level in the pool be? Change? The physicist immediately judges that the water level will rise because he thinks that when the stones in the boat are thrown into the water, the pool water will “expand” because the stones account for a certain volume. After Tian Tian and his classmates saw this story, they also developed great interest. What is the reality? Physics is a discipline based on experiments. Therefore, we decided to use a large beaker simulation pool, a small beaker simulation boat, and hands-on experiments to illustrate
