As part of the transition from a quarter to a semester calendar system the Physics Department has designed and is implementing a new course in experimental physics for incoming students who are seriously interested in physics. The purpose of the course is to excite students about experimental science and help them develop an understanding of how experiments are designed, assembled and carried out. The course may attract and retain more physics majors. The experiments are based on a relatively limited number of topics which can be investigated experimentally with a minimum of theoretical background. Initial experiments include: 1) the geometrical optics of a telescope; 2) construction and properties of vacuum systems; 3) thermal cooling in a vacuum; and 4) production of thin metallic films and measurement of their electrical resistivity. As the course develops new experiments will be added including simple analogue and digital electronics and the use of analogue and digital methods to measure the output of an electrical sensor. Wherever possible special emphasis is being placed on how computers can be used to take, analyze and simulate data. The laboratories are open ended with emphasis on the acquisition of experimental skills and knowledge.

作为从四分之一日历制向学期日历制过渡的一部分，物理系为对物理真正感兴趣的新生设计并正在实施一门新的实验物理课程。本课程的目的是激发学生对实验科学的兴趣，并帮助他们理解实验是如何设计、组装和进行的。这门课程可能会吸引和留住更多的物理专业学生。这些实验基于相对有限的主题，这些主题可以在最少的理论背景下进行实验研究。最初的实验包括：1)望远镜的几何光学；2)真空系统的结构和性质；3)真空中的热冷却；以及4)金属薄膜的制备及其电阻率的测量。随着课程的发展，将增加新的实验，包括简单的模拟和数字电子学，以及使用模拟和数字方法测量电子传感器的输出。在可能的情况下，特别强调如何使用计算机来获取、分析和模拟数据。这些实验室是开放式的，重点是获得实验技能和知识。
