S1 E1
·
2016

Many inventions have allowed people to build bigger and better, but which one was the one that revolutionized the challenge of height? Concrete? Steel? Not really... It is in fact the elevator! Indeed, without it, who would have accepted to live on the 40th floor? From the Tower of Babel to the Jeddah Tower in Saudi Arabia, Man has always wanted to build in a more imposing and impressive way and above all to get closer and closer to the sky. What exactly are the whys and wherefores of this conquest of height? And is there a limit?

E7 : Les conquérants des sommets

52min31s
Until the end of the 17th century, mountains were simply considered as geographical obstacles, barren, useless and above all frightening lands.

E8 : Les conquérants des pôles

52min37s
For many years, the conquest of the poles has been a real competition: many have tried, many have failed, sometimes so close to the goal. Today, the challenge is no longer to reach the Arctic and Antarctic, but rather to study these two regions and find the real reasons for the melting ice. Witness a century of conquest and follow in…
