Tribute to Madeleine L'Engle: The Tesseract

Here's a fascinating little film put together by NPR's Bryant Park Project as a tribute to Madeleine L'Engle and her novel, A Wrinkle in Time, which makes use of the "tesseract," a rather confusing and imaginative appreciation of the fourth dimension. NPR interviewed Physicist David Morgan to explain how the tesseract functions to illustrate multidimensional space. Very cool...but the film's file is big...so be patient and let it load first-- it's worth it. You can also click on the little box in the lower right hand corner of the film and see the film full screen.
