A Scientific Voyage

This program features the best stories from the last three seasons, including an interview with one of eight Biospherians sealed inside an artificial environment for a little over two years; a visit to the Galapagos Islands where Darwin developed his discoveries on natural selection; the affects of climate change on glaciers all over the world; and a look at the Hadron Collider, the world's largest particle smasher.
