伟大的物理学突破很少包括在物理学或天文学入门课程中。广义相对论和双黑洞合并没有什么不同，只能在非常有限的意义上包括在入门课程中。然而，我们可以设计直接涉及GW150914探测的活动，这是2015年9月14日探测到的引力波信号的名称，从而让学生直接参与这一令人兴奋的发现。这些活动自然不包括建造探测器或探测引力波。相反，我们将其设计为包括对来自GW 150914的数据的分析，其中包括一些针对入门课程学生的有趣分析活动。同样的活动可以作为实验练习或计算项目分配给相同的学生群体。这里使用的分析工具很简单，可供目标学生群体使用。它不包括LIGO用来仔细分析探测到的信号的复杂分析工具。然而，这些简单的工具足以让学生获得重要的结果。
Great physics breakthroughs are rarely included in the introductory physics or astronomy course. General relativity and binary black hole coalescence are no different, and can be included in the introductory course only in a very limited sense. However, we can design activities that directly involve the detection of GW150914, the designation of the Gravitation Wave signal detected on September 14, 2015, thereby engage the students in this exciting discovery directly. The activities naturally do not include the construction of a detector or the detection of gravitational waves. Instead, we design it to include analysis of the data from GW150914, which includes some interesting analysis activities for students of the introductory course. The same activities can be assigned either as a laboratory exercise or as a computational project for the same population of students. The analysis tools used here are simple and available to the intended student population. It does not include the sophisticated analysis tools, which was used by LIGO to carefully analyze the detected signal. However, these simple tools are sufficient to allow the student to get important results.
