Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way...

Physicist Dr Helen Czerski explores the narrow band of temperature that has led to life on Earth. She reveals how life began in a dramatic place where hot meets cold, and how every single living creature on Earth depends on temperature for its survival. She uncovers the extraordinary natural engineering that animals have evolved to keep their bodies at the right temperature. And she witnesses the remarkable surgery that's using temperature to push the human body to the very brink of life.

A unique and captivating documentary on the story of humanity's quest to measure time. Who invented time, who invented the clock? Why 1 hour, why 60 minutes, why 60 seconds? Since prehistoric times, man has sought to measure time, to organize social and religious life, to plan food supply... Today we can surf the Internet, geolocate, pay by credit card ... All our daily lives depend on time and the synchronization of clocks. The history of the invention of time and of the ways and instruments to measure it is a long story... Controlling Time, one of Humanity's biggest obsessions. First, man began to calculate the observable phenomena of time using incredible astronomical measuring instruments. Calendars were born. Then, he sought to quantify ever more precise durations, with ever more sophisticated machines, in order to establish a social, conventional time, the same for all. Today, this time, inscribed on our smartphones, is established by atomic clocks which have become the keystone of our digital world. Not without enormous industrial and economic challenges at stake. Through what major technological breakthroughs have we succeeded in controlling time, to the point of being able to make its ultra-precise factory the foundation of our interconnected society? From France to Greece, through Italy, England, and Switzerland, a group of experts —astrophysicists, engineers and historians — follows in the footsteps of genius inventors who forged our perception of time and our relationship to the world. For better and for worse. This film delves into the invention of time & ways to measure it. Don't waste time and be sure to make time to watch this fascinating film!
