This project supports the creation of a center for the study of relativity. The center is housing the equipment for students to study the effects of relativity through three activities. The first activity involves the measurement of the speed and lifetime of cosmic ray moons. These measurements confirm that the speed of light is the maximum speed, and that the moon lifetime is dilated during flight. The second activity verifies the relativistic relationship between energy, momentum, and velocity by measuring the energy of betas from a radioactive source after they have passed through momentum and velocity selectors. The third activity investigates relativistic effects with computer calculations that model phenomena such as scattering. Advanced students are conducting research projects in the center using the new computer. The laboratory is also serving as a center for recruitment. The walls have posters, photographs, and explanations of the equipment and calculations. Results of research by students are also being prominently displayed. This tactic allows potential majors to feel the excitement of scientific research experienced by their peers. This center is, therefore, serving an important recruitment tool, as well as a state-of-the art laboratory and research station.

该项目支持建立一个相对论研究中心。该中心为学生提供了通过三项活动学习相对论影响的设备。第一项活动涉及测量宇宙线卫星的速度和寿命。这些测量证实了光速是最大速度，月球的寿命在飞行过程中被扩大了。第二个活动通过测量来自放射源的贝塔通过动量和速度选择器后的能量来验证能量、动量和速度之间的相对论关系。第三个活动用计算机计算来研究相对论效应，这些计算机计算模拟了散射等现象。高级学生正在使用新计算机在中心进行研究项目。该实验室也是一个招聘中心。墙上有海报、照片，以及对设备和计算的解释。学生的研究成果也在显著位置展示。这一策略让潜在的专业学生感受到了同行经历的科学研究的兴奋。因此，该中心是一个重要的招聘工具，也是一个最先进的实验室和研究站。
