Is it possible that I can get a Duke University user account to access math videos? I am an independent student of math and want to use many interesting video courses. Unfortunately the math video courses of Duke university are unavailable for others. So I want to know


  Is there any way to access these courses or is it possible that to get a temporary (and free) user account from Duke University?
As a commentor wrote, "ask Duke". In practice, that means the following.

Note from the URL that the page is maintained by the math department. If you can, try to figure out who specifically is maintaining the webpage (i.e., a person's name), and contact them. Otherwise, I'd recommend writing to anyone in a position of responsilibity in their math department -- say, the graduate director. Tell them that you are interested in watching their videos, and ask if there's any way you could be permitted to do so.

The most likely outcome is either that they say no, or that you get no response at all -- but in my estimation it's okay to ask, and they might say yes.
