Once you have a good understanding

一旦对问题有了很好的理解，就应该问自己一个问题：我是否可以通过做出一些合理和合理的假设来简化问题，并获得适当的解决方案？了解物理和基本概念以及何时何地应用它们及其局限性，将使您在做出假设和解决问题时受益匪浅。

一旦你对这个问题有了很好的了解，你应该问自己这个问题：我可以通过做出一些合理和合乎逻辑的假设来简化问题，同时获得适当的解决方案吗？了解物理概念和基本概念，以及何时应用它们及其局限性，将大大有助于您做出假设和解决问题。

Once you have a good understanding of the problem, you should then ask yourself this question: Can I simplify the problem by making some reasonable and logical assumptions and yet obtain an appropriate solution? Understanding the physical and the fundamental concepts, as well as where and when to apply them and their limitations, will benefit you greatly in making assumptions and solving the problem.<br>
