The old paradigms website has been converted to a static site. Unfortunately, that process has resulted in some links becoming broken, depending on the original URL used to access the site. If you encounter broken links while browsing this website, try starting at http://physics.oregonstate.edu/coursewikis/portfolioswiki rather than at the official (old) URL, which was http://physics.oregonstate.edu/portfolioswiki. (You can also try manually adding "coursewikis" in front of "portfolioswiki" in the URL, and/or converting "physics/physics" to "physics".)
