- 什么是物理专业？
物理学（physics）是研究物质最一般的运动规律和物质基本结构的学科。作为自然科学的带头学科，物理学研究大至宇宙，小至基本粒子等一切物质最基本的运动形式和规律，因此成为其他各自然科学学科的研究基础。同时，物理专业，特别是力学及电磁学方面，也是工程专业学科必修的基础知识，美国大学本科的物理主要会分为理论物理及应用物理两方面，大部分学校会在大一大二时进行物理各个分支（力学、电磁学、热力学、量子力学、广义及狭义相对论、光学等）进行基础学习，学生根据自己之后的兴趣点及就业倾向，从大二下或大三开始专攻1-2个领域进行深入研究。
以下将以加州大学伯克利分校的物理专业为例，介绍他们的concentration及课程设置
UCB Physics： The Physics major is designed to give the student a broad and thorough understanding of the fundamentals of physics. Therefore, the emphasis is on this general understanding rather than on specialized skills, although some specialized courses are among the options open to the student. Those considering a physics major are urged to consult a departmental adviser early, in order to discuss the content of the major and also the opportunities after graduation. Recent graduates have entered graduate work in a number of scientific fields, and others have gone on to jobs in academic, industrial, and government laboratories.
物理专业的研究范围非常广泛，小到粒子，大到宇宙，都是其研究领域。物理专业的学生需要拥有较强的数学及分析能力、实验能力、理解能力，以及写作及口语沟通能力等。
