Data emisji: Sie 02, 2005
From a giant machine press that stamps out an entire car body to a 125-ton chainsaw that cuts through the world's hardest rock; from a huge telescope that glimpses the ends of the known universe to the world's largest rock crusher. Join us for a workout of the world's largest machines, and take a long look through the lens of the world's biggest optical telescope, the Keck Observatory, atop 13,800-foot Mauna Kea in Hawaii.
