Mathematics in Movies is a website developed by Oliver Knill who is a Harvard Mathematics professor. While browsing around Mathematics in Movies I was surprised to see the size of their collection of movie and television clips. For each clip there is the title of the show/movie and a quick link to a math concept. The clip that immediately stood out to me was Oscar from the The Office explaining to Michael the definition of a surplus. Click here to check it out.
Mathematics in Movies is a great site for introducing a concept or reinforcing a concept after it has been taught. I could also be a good way for students to review by browsing the library of clips. What's nice about this site is that they also provide a link to the .mp4 version which you can download and show offline. You can even concert that file to a .flv and use it in Smart Notebook.
