Now you have a chance to study at Stanford for free. They are opening their course to the public for the first time. They will not open all courses, but only limited to several introduction subjects and also artificial intelligent courses.
In the past, they have uploaded several videos to YouTube and now they are opening their courses to public. It's what the Wikinomics said about mass collaboration could change everything. Now you can study at Stanford right in front of your computer at home or at mall.
MIT has also done the same thing via their MIT Open Courseware. Soon, universities all around the world will be able to share their materials and people could study from abroad.
