This project leads to a series of laboratory modules that, as a whole, compose a laboratory for physics majors, but individually are appropriate for courses in chemistry and astronomy. Each module is being built upon an experiment that determines a fundamental constant or important physical constant. The experiments are clearly distinct from the traditional chemistry or astronomy experiments both in the nature of the information sought and, in many cases, by the techniques and processes used. They do, however, serve as an integral part of these courses. In each case, the goal is to emphasize the role that physics plays in the discipline it supports while simultaneously identifying it as a distinct discipline. The educational goals of the experiment are to (1) have students appreciate the relevance of the supporting physics experiment since it is carried out within the related nonphysics course; (2) maximize the number of students that are exposed to landmark physics experiments; and (3) increase the student's appreciation of the distinctive nature of physics as a discipline. The experiments are designed to (1) be carried out with only computer-aided instruction; (2) use computer interfaces to allow for high- precision work and to support calculations; and (3) measure fundamental constants that have a direct impact on the associated course.

该项目导致一系列的实验室模块，作为一个整体，组成物理专业的实验室，但单独适用于化学和天文学课程。 每个模块都是建立在一个实验，确定一个基本常数或重要的物理常数。 这些实验与传统的化学或天文学实验在所寻求的信息的性质上以及在许多情况下所使用的技术和过程上都有明显的区别。 然而，它们确实是这些课程的一个组成部分。 在每一种情况下，目标都是强调物理学在它所支持的学科中所扮演的角色，同时将其确定为一个独特的学科。 实验的教育目标是：（1）让学生欣赏支持物理实验的相关性，因为它是在相关的非物理课程中进行的;（2）最大限度地增加接触具有里程碑意义的物理实验的学生数量;（3）增加学生对物理学科独特性质的欣赏。 实验设计为（1）仅使用计算机辅助教学进行;（2）使用计算机界面以允许高精度工作并支持计算;以及（3）测量对相关过程有直接影响的基本常数。
