Hi! My name is Robert Hannah and I'm a physics/ mathematics major at the University of Sydney. I believe that all educational resources should be free. The attitude that the author of such resources "owns" what s/he has written is harmful and places personal gain ahead of the general benefit of society that would otherwise result. The counterargument that repealing copyrights of educational material would severly disincentivize authorship is clearly wrong in light of the wealth of free, high-quality educational resources already available. Significant examples:

-> The Khan Academy:

-> MIT OpenCourseWare:

-> Academic Earth:

-> Wikipedia Itself :P
