Helen Czerski ventures beyond the visible spectrum in the final (and best) episode in this vibrant little series, showing how electromagnetic radiation is so much broader than the narrow slice of reality we see with our eyes. Before delving into the details of UV, infrared and x-rays, Dr Czerski explores colour subjectivity by trying on a dress that recently divided the internet — to some it appeared blue and black, to others white and gold. It's a perfect fit. It's also a neat analogy of how people can have opposing views but both swear blind that their perspective is correct. The series ends with some amazing imaging techniques that show our bodies in a whole new light.

Where Am I? Is a new documentary about the skills we use to find our way around. Whether you are an Inuit hunter, a foraging insect, or just someone out for a stroll, your brain is performing one of its most fundamental services – it’s navigating. Why are some of us good at finding our way, while others are not? Good navigators are able to use both memory and imagination…remembering where they have been, and imagining where they’re going. Some researchers believe we build a cognitive or mental map when we navigate, a kind of bird’s eye view of our surroundings, a view that can be rotated and examined in our mind. There has been about sixty years of argument amongst scientists about whether humans and other mammals actually form these cognitive maps or not. The advent of GPS or Global Positioning Systems has changed the discussion about navigation. GPS triggers a simpler, more automatic navigational technique that does not involve building a mental map. With GPS, we simply respond to directions and may not truly understand where we are.

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!
