From the website:
Academic Earth believes that everyone has the right to a world-class education. Recognizing the existing barriers in academia, we continue our efforts to curate an unparalleled collection of free online courses from the world's top universities. Moving forward, we honor the egalitarian spirit of Academic Earth's founders as we develop a platform to facilitate the global sharing of ideas, both inside and outside the classroom.
In addition to our comprehensive collection of free online college courses, Academic Earth features an ongoing series of original videos. These videos tap into our belief that a great deal of learning happens outside the classroom in those unstructured moments when provocative questions are raised, debated, and sometimes answered. We embrace intellectual curiosity and encourage the Academic Earth community to share our videos to launch their own discussions. After all, only through questioning the world around us, can we come to better understand it.
For example, there are 47 video lectures "Fundamentals of Physics, I and II" by Ramamurti Shankar, the John Randolph Huffman Professor of Physics at Yale University, in New Haven, Connecticut. Each video is over 1 hour duration.
Also, 27 45-50min video lectures in Quantum Mechanics by Professor James Binney, a British astrophysicist. He is a professor of physics at the University of Oxford and former head of the Sub-Department of Theoretical Physics as well as an Emeritus Fellow of Merton College
These online courses are free!!!
