The Lecture Demonstrations Facility is part of the physics department at North Carolina State University, and is tasked with supporting the teaching activities of the department's faculty and graduate students. This website features a number of online demonstrations that can be used by outside parties, who can click on the Visitor Access area to view some of these great videos. The demonstrations are divided into nine areas, including Optics, Modern Physics, and Waves and Oscillations. Each of these areas contains subtopics that will help users identify the specific subject of the demonstration, such as heat transfer applications or phase changes. Moving on, the Other Resources area includes online demonstration manuals from dozens of other schools, including Columbia University, Carnegie Mellon, and Macalester College.
