From the Massachusetts Institute of Technology's OpenCourseWare series comes this extensive collection of materials for teaching and learning about mechanical engineering. These materials, which include syllabi, videos, slide presentations, course readings, lecture notes, exams, and more, were developed by MIT faculty for a variety of undergraduate and graduate classes taught at the university. For instance, in Engineering Math: Differential Equations and Linear Algebra visitors can view a series of 80-minute recorded lectures in which Dr. Gilbert Strang explains how to perform first-order and second-order equations. Here, visitors can also follow a link to a series of 55 shorter videos that Strang developed, along with Dr. Cleve Moler, for iTunes University. Meanwhile, in Advanced Fluid Mechanics, visitors can check out extensive class notes, problems sets, and accompanying videos for 11 different units. In total, twelve different courses are offered. Visitors may choose to browse individual courses for materials of interests or to download all materials pertaining to a single course as a ZIP file.
