In this post I'm going to talk about the pipe that our group made for mini project 3.

You can find the pipe at pipes.yahoo.com/physicspipe. Our pipe combines the information from About.com, the MIT website, and Reddit.com for the most up to date physics information. The pipe sorts each new entry by the published date in ascending order. There are also more general information, such as good physics books to read, a planet found to have a tilted orbit around a distant star, infromation concerning the 4th dimension and even stuff about the string theory.
Basically the pipe has three feeds that are brought together with the "union" operation and then sorted, leading to the pipe output.
