物理学是自然科学的最基本基础，是所有其他科学的基础。物理学涉及运动，物质结构以及负责该运动和结构的潜在力。它涉及从亚原子到宇宙学，从普朗克时代到宇宙时代的所有长度和时间尺度的现象。物理学家具有从最基本的层面理解复杂现象的能力，因此具有在众多领域从事职业和研究生研究的独特资格，包括工程，计算机科学和建模，可视化，航空航天，航空，金融预测，通信，气象，能源和卫生部门，天文学，数学等等。简而言之，物理学家经过训练和聘请思考。
Physics is a science that deals with the origin and structure of matter in the universe, nature's forces that govern how they interact and applications of physical phenomena in our everyday life. Physicists study the matter at all length scales, from sub-atomic particles that make up everything around us to star-studded galaxies to try and understand the fundamental laws and relationships that govern the known universe. Physics has profound uses in our society, including electricity, electronics, mechanics & motion of matter, lasers, imaging and therapy in medicine, and power generation.<br><br>The undergraduate program in physics provides a comprehensive breadth of knowledge in all the basic subjects of physics. This dynamic program features an interactive learning atmosphere.<br><br>Saint Mary's faculty are leading nationally and internationally in research in subatomic physics. Undergraduate students get work exposure working at international scale large accelerator facilities.
