牛顿曾指出:自然界喜欢简单化,而不爱用多余的东西夸耀自己.在物理解题中,若能大胆进行变通、联想、迁移、类比和假设等思维活动,便能体验到简单美.一旦寻求到最简解题途径,就会令许多错综复杂、运算繁琐的问题迎刃而解,起到“四两拨千斤”的奇效. Newton once pointed out that nature likes to be simple and does not love to boast about itself with extra things. In the matter of understanding, if we can boldly carry out thinking activities such as adaptability, association, migration, analogy and hypothesis, we can experience simple beauty. The search for the simplest way to solve problems will solve many problems that are complicated and computationally tedious, and play a miraculous effect.
