The Wheel

14th May 2002 44 mins Season 9 Episode 18

Spinning your wheels isn’t just going around in circles. In fact, it’s revolutionary–literally. The history of civilization has turned on the wheel, and we have traveled as far as we have because of it. One of the six simple machines and perhaps the most important invention in the history of mankind, the wheel has been essential in all aspects of life–from farming to fighting, traveling to trading. Features interviews with scientists, historians, philosophers, millers, potters, and spinners.

Star City

Star City, the Gagarin Center for Training Cosmonauts, was established by the former Soviet Union in the 1960s as a school for the future conquerors of space. Today, it’s where Russian cosmonauts and international guests train on Soyuz rocket simulators and the MIR complex simulator. We join cosmonauts as they undergo grueling ground training in survival courses and parachuting, and face some of Star City’s toughest challenges–G-Force simulators, space orientation, and rescue training.
