Greece, a land of breathtaking beauty and light. A land where science, art and inspiration from the gods combined to produce some of the world's greatest marvels of architecture and design. The ancient Greeks used buildings and structures to reflect the variety of life at the core of their civilisation - they built the first theatres, staged the first sports events and worshipped in some of the most spectacular temples ever built. From prehistoric palaces to bold symbols of victory this programme explores the Seven Ancient Wonders of Greece - the Theatre of Epidaurus, Olympia, Delphi, the Colossus of Rhodes, Santorini, The Palace of Knossos and the greatest masterpiece of them all - The Parthenon. Revealing the true icons of this incredible civilisation, we explore how and why the seven wonders of Ancient Greece still retain the power to amaze the world today. By recounting the stories behind the people who designed and oversaw their construction and unravelling the tales and myths of those who lived within them, we unearth the secrets behind The Seven Wonders of Ancient Greece.
Blade implements have been a part of civilized man's arsenal since the Paleolithic Age, when sharp tools were chipped off of flint or obsidian. But with the discovery of metallurgy, people were able to forge stronger, more versatile blade implements. We visit an axe-throwing contest in Wisconsin for an introduction to the least subtle of the blade tools. Then we visit a swordsmith and an experienced swordfighter who work in traditional methods from ancient sources, and review the history of knives.
From chariot wheels of ancient Egypt to hard disks in a computer to the wheels on a Mars rover, machinery can't function without lubricants. And in today's technology, there are a mind-boggling number of friction points that must be lubed, and a staggering number of lubricants petroleum motor oils that keep car engines from burning up, synthetic greases that stay put in the zero gravity of space, and solid coatings that prevent eggs from sticking to a pan. We'll see how this marvel of chemistry works and how it's used…
From LAPD's sharp shooters to Army snipers, discover what it means to be armed and accurate. Learn how ancient ballista and trebuchet could repeatedly strike their targets.

Finally, watch as Cirque de Soleil's daring artists are both projectile and target as they perform their breathtaking feats.
The story of rubber is more than tires, toys, gloves, and gum it's imbedded in modern life, from the controversial Challenger O-rings to seals on hydrogen fuel cells. A gigantic worldwide synthetic rubber industry creates exotic elastomers for high-tech applications, while China's rapid industrialization plays havoc with the world's natural rubber supply. From the ancient Olmecs of Yucatan, who knew the secret of vulcanization, to modern processing plants, we trace rubber's history and future.
