It’s a safe bet that Professor Michael Short’s 22.01 Introduction to Nuclear Engineering and Ionizing Radiation is the only course at MIT where students are encouraged to bring their toenail clippings to class. In this episode, Professor Short discusses one of the core principles of his teaching philosophy: the importance of making abstract concepts tangible by means of hands-on activities. Want to know how much gold or arsenic is in your body? Bombard the aforementioned toenail clippings with neutrons in a reactor and see what gamma rays they give off! Want to know whether the stone in your ring is a genuine diamond or just a cubic zirconia? Put it under the electron microscope! Professor Short also emphasizes the value of opening “knowledge gaps”—awakening his students’ curiosity by focusing on interesting questions they don’t yet know the answer to. Later, Professor Short describes how he designed the course with a built-in mechanism for collecting real-time feedback so that he can respond immediately to students’ concerns. As a bonus, near the end of the podcast, Professor Short answers various nuclear science questions posed by actual OpenCourseWare users. Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalProfessor Short’s Nuclear Engineering and Ionizing Radiation course on OCWProfessor Short’s Do-It-Yourself Geiger Counters on OCWProfessor Short’s faculty pageBlog post on Professor Short’s work in MongoliaMusic in this episode by Blue Dot SessionsConnect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.
