物理是我们理解自然的基石。任一实质性的物体或过程，甚至是宇宙本身都是物理学的研究对象。物理学研究一系列非常复杂的系统，从最小的亚原子粒子到在生物细胞或地球气候中发现的最复杂过程。物理学课程中学到的一套综合基础的工具可以运用到许多领域解决各种问题。
Physics forms the bedrock of our understanding of Nature. Any physical object or process, or even the structure of the universe itself, can be the subject of physics. Physicists study an extremely diverse array of systems, from the simplest subatomic particles to the most complex processes found in biological cells or in the Earth\\\\\\\'s climate. Physics courses provide a comprehensive set of fundamental tools that can be brought to bear on many problems across a variety of fields.
