A sword made of pure light that can cut through anything, the lightsaber is a truly awesome weapon. But it's not just a science fiction fantasy, Dr Michio Kaku reveals how we could one day build a real working lightsaber.
Defying gravity and hurtling through space: the flying saucer is the ultimate science fiction vehicle. Using cutting-edge research and theoretical physics, Dr. Michio Kaku reveals how one day we could all be using the aliens' favorite mode of transport.

Film telling the story of the greatest physicists of the 20th century and the discoveries they made, told in their own words. Men and women who transformed our understanding of the universe, from unlocking the secrets of the atom to solving the mysteries of the cosmos.
Jim Al-Khalili investigates the amazing science of gravity, recreating groundbreaking experiments, including the moment when Galileo first worked out how to measure it. He investigates gravity waves, finds out from astronauts what it's like to live without gravity, sets out to find where in Britain gravity is weakest and so where we weigh the least, and helps design a smartphone app that volunteers use to demonstrate how gravity affects time and makes us age at slightly different rates.

This two-part scientific detective tale tells the story of a remarkable group of pioneers who wanted to reach the ultimate extreme: absolute zero, a place so cold that the physical world as we know it doesn't exist, electricity flows without resistance, fluids defy gravity and the speed of light can be reduced to 38 miles per hour. Each film features a strange cast of eccentric characters, including: Clarence Birds Eye; Frederic 'Ice King' Tudor, who founded an empire harvesting ice; and James Dewar, who almost drove himself crazy by trying to liquefy hydrogen. Absolute zero became the Holy Grail of temperature physicists and is considered the gateway to many new technologies, such as nano-construction, neurological networks and quantum computing. The possibilities, it seems, are limitless. Part 2: Race for Absolute Zero Focuses on the fierce rivalry that took place in the laboratories in Britain, Holland, France and Poland as they sought the ultimate extreme of cold. The program will follow the extraordinary discoveries of superconductivity and superfluidity and the attempt to produce a new form of matter that Albert Einstein predicted would exist within a few billionths of degrees above absolute zero.
Physicist Jim Al-Khalili routinely deals with the strangest subject in all of science - quantum physics, the astonishing and perplexing theory of sub-atomic particles. But now he's turning his attention to the world of nature. Can quantum mechanics explain the greatest mysteries in biology?
In this extraordinary documentary we are going to witness very different kinds and situations of snowing: from howling blizzards to the gentlest and loveliest of weather events, from huge handkerchiefs quietly falling to the needle-sharp attack of hard, heavy grains. Snow - what is it really? How is it created - naturally and artificially? Thanks to CGI and new camera techniques we can actually see this process for the first time and listen to the incredible, inaudible music of snowfall, of myriads of tiny crystals touching and rolling and settling. Each snowflake is unique and bears more secrets than we could imagine. Did you know that different kinds of music influence the crystallization process and the shape of snowflakes? And have you ever imagined that we would be able to produce artificial snow that melts at 30 degrees Celsius? With this in mind: just let it snow!

Join Brian Greene on a wild ride into the weird realm of quantum physics, which governs the universe on the tiniest of scales. Greene brings quantum mechanics to life in a nightclub like no other, where objects pop in and out of existence, and things over here can affect others over there, instantaneously and without anything crossing the space between them.
