Professor Jim Al-Khalili discovers the intriguing story of how we discovered the rules that drive the universe. (Part 2: The Story of Information) Professor Jim Al-Khalili investigates one of the most important concepts in the world today - information. He discovers how we harnessed the power of symbols, everything from the first alphabet to the electric telegraph through to the modern digital age. But on this journey he learns that information isn't just about human communication, it's woven very profoundly into the fabric of reality.

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.

Professor Jim Al-Khalili discovers the intriguing story of how we discovered the rules that drive the universe. (Part 1: The Story of Energy) Energy is vital to us all, but what exactly is energy? In attempting to answer this question Jim investigates a strange set of laws that link together everything from engines to humans to stars. It turns out that energy, so critical to daily existence, actually helps us make sense of the entire universe.

Visiting a hidden location buried beneath the hills of Scotland, Helen experiences some of the most extreme acoustics in the world. Here she learns just how much information can be carried by sound. She discovers how sound has driven the evolution of truly incredible biological systems and complex relationships between creatures that exploit sound for hunting - and escaping from predators. Helen demonstrates how sound waves diffract (bend around objects) and in doing so help us sense danger and locate it. Helen explains how we are not limited to passively detecting sound waves; we can also use them to actively probe the world.

Professor Iain Stewart reveals the story behind the Scottish physicist who was Einstein's hero; James Clerk Maxwell. Maxwell's discoveries not only inspired Einstein, but they helped shape our modern world - allowing the development of radio, TV, mobile phones and much more. Despite this, he is largely unknown in his native land of Scotland. On the 150th anniversary of Maxwell's great equations, scientist Iain Stewart sets out to change that, and to celebrate the life, work and legacy of the man dubbed 'Scotland's Forgotten Einstein'.
