Kent Simon writes: Many people may not know that MIT has initiated OpenCourseWare, an initiative to share all of their educational resources with the public. This act of philanthropy is intended (in classical MIT style) to make knowledge free, open, and available. This is a great resource for people looking to improve their knowledge of our world, which is exceptionally beneficial to those who may not be able to afford the quality of education offered at a school like MIT. You can access all currently available courses here. It is expected that by the end of the year every course offered at MIT will be available on the OpenCourseWare site. This includes lecture notes, homework assignments, and exams. This is not something offered to replace collegiate education, but rather to spread knowledge freely.
