Using Saran Wrap As A Polarizing Filter

Posted by timothy on from the now-shake-an-egg dept.

cdneng2 writes "Here's a University of Toronto research paper on how to use ordinary Saran Wrap as a polarized filter to turn your laptop into a stereoscope. From the paper, cellophane (costing mere pennies) proved to be a better half-waveplate than a commercial half-waveplate (costing hundreds of dollars for the required size) for rotating the polarization of white light. The same paper is cited in www.mygeekdom.com." Cellophane wonders may never cease.

    I think what makes this dupe particularly amusing (poignant? telling?) is the fact that it links to the article it duplicates. Sheesh, don't these editors read anything?

      I don't know what you guys are getting so worked up about.
      "Stereoscopic technique for generating 3D displays from cellophane and a laptop"
      doesn't sound anything like
      "how to use ordinary Saran Wrap as a polarized filter to turn your laptop into a stereoscope"
      to me! I mean... "polarized". Definantly some new information there, right?

    So how does an editor manage to link to the original story on slashdot, which references the same article link, without realizing it's a duplicate?

      Lazy. Lazy.

      Here's some links. Cellophane is made from cellulose.

      While plastic wrap (aka Saran Wrap) is made from "plastics" like PE and PVC.

      Unlike many english names. These ones make some sence.

    Dude, put the articles side-by-side and cross your eyes. You'll see it in 3D!
