许多物理问题,由于物理现象涉及的因素多,过程复杂,用常规思路和方法难以洞察其变化规律并做出迅速判断。但如果把它推到极端状态下或特殊状态下进行分析,问题会立刻变得明朗直观,这种解题方法我们称之为极限思维法,也叫极端法。运用极限思维思想解决物理问题,关键是考虑将什么问题推向哪个极端,即 Many physical problems, due to physical phenomena involving many factors, the process is complex, with the conventional ideas and methods difficult to understand its changing laws and make rapid judgments. But if it is pushed to the extreme state or under special conditions for analysis, the problem will immediately become clear and intuitive. This problem-solving method is what we call the extreme thinking method, also called extreme law. The key to using extreme thinking to solve physical problems is to think about what problem to push to which extreme
