物理学和天文学是旨在发现控制我们宇宙的基本原理的基础科学。物理学家研究空间，时间，物质和能量之间的相互作用。自然界中的复杂行为是根据构成元素与绑定它们之间的力之间的基本关系来解释的，范围从亚原子到宇宙尺度。天文学涵盖了地球以外的整个物理宇宙：太阳系，恒星，星系，星系团和超团簇，类星体以及宇宙的大规模结构。物理和天文学的基本工具是对我们周围世界的数学，实验研究和观察。<br> <br>在宾夕法尼亚州，本科物理专业的课程（包括丰富的实验室经验）基于凝聚态的教职员工实力物理学，基本粒子物理学和天体物理学。本科教
Physics and astronomy are fundamental sciences aimed at discovering the basic principles that govern our universe. Physicists study the interplay between space, time, matter, and energy. Complex behavior in nature is explained in terms of elementary relations between constituent elements and the forces that bind them, over distances ranging from subatomic to cosmic scale. Astronomy encompasses the entire physical universe beyond the earth: the solar system, stars, galaxies, galaxy clusters and superclusters, quasars, and the large-scale structure of the universe. The basic tools in physics and astronomy are mathematics and experimental investigation and observation of the world around us.
