This remarkable science-history series investigates the blistering pace of human endeavour in space exploration, computing, energy, resources, Earth science and our understanding of the evolution of life itself. Across the last 50 years, humans have set a blistering pace and scientific discovery. We've crossed the boundaries of our solar system, made machines that can learn harnessed the power of the sun and built life from scratch. It's a period like no other in history, where human endeavour is changing everything: this is The Great Acceleration. As we race toward the future, we must examine the journey.
In the first episode, Dr Shalin Naik explores the ambitious space shuttle mission that began in the '70s plus the future colonization of Mars. Over the past 50 years, space has become central to everything, from communications to entertainment to climate modelling. And as private enterprise enters space exploration, our understanding of the universe will only continue to expand. We will know if we can survive on other objects - the moon, maybe Mars, maybe even some of the moons of Jupiter and Saturn. Deep space is the last and infinite frontier. That's what we do as human beings. We explore, we learn, we make discoveries, from the moment we're born to the moment we die.

In this mind-bending series, Professor Jim Al-Khalili explores the vast range of size in the universe, from tiny atoms to gigantic, interconnected galaxies.
In the first episode, Jim will enter the world of objects that are too tiny to glimpse with the naked eye. Starting with the smallest insects, he moves on to encounter living cells with amazing superpowers and confronts some of humanity's deadliest enemies in the form of viruses. Going smaller still, he encounters wondrous new nanomaterials such as graphene, discovered by physicist Andre Geim. These are revolutionising engineering, medicine, computing, electronics and environmental science. Finally, Jim comes face to face with the fundamental building blocks of the world around us – atoms – and reveals why understanding the science of the 'small' is crucial to the future of humanity.

'The Coldest War': With the polar ice caps shrinking due to global warming, new trade routes are being exposed, along with billions of dollars' worth of natural-resource reserves. The five nations bordering the Arctic are readying themselves to fight for it. The problem is that there's one non-NATO country that already considers itself rightful owner of the region: Russia. With Vladimir Putin's recent military annexation of Crimea, there's a definite possibility its aggressions will boil over, returning the international community to precarious Cold War footing. We will head north to witness NATO forces participating in the largest polar military exercise in history. 'Heroin Warfare': Since the U.S. occupation of Afghanistan, heroin production in the region has skyrocketed, making the country the number-one producer by a large margin. Though Iran, Afghanistan's neighbor, is an ultraconservative country, Afghan heroin flowing across the border has actually caused Iran to have the worst heroin use problem in the world. Suroosh Alvi gets a rare look inside Iran to meet the suffering heroin addicts, and see how the country is coping with the illegal drug trade.

In 1914, Russia entered World War I in response to Austria-Hungary's declaration of war on Russia's ally Serbia. This was fought across multiple fronts while isolated from its allies. The Battle of Tannenberg, where the entire Russian Second Army was annihilated, cast an ominous shadow over the empire's future. The already-existing public distrust of the regime was deepened by the rising costs of the war and rumours of corruption. World War I takes Nicholas to the front. Back home, outrage grows over high casualties and Alexandra and Rasputin's political intrigues.

Nicholas felt enormous pressure to continue the dynasty and expand the empire. He saw his opportunity in the Far East. This brought him into conflict with a rising power, Japan. Russia's disastrous war against Japan prompts civil unrest. The birth of Prince Alexei is incredibly important. He's the long-awaited son that they had hoped so much for. But when Alexei is diagnosed with haemophilia, Siberian mystic Rasputin steps in. He's very good at realizing when something is open that will enable him to increase his power and wealth. The pressure of keeping the secret of Alexei's illness affects the political decisions that Nicky and Alix made for the rest of their reign.

The Romanovs retreat into a bubble of luxury while the czar's forces brutally suppress protests by a starving populace. Rasputin's influence grows, never mind the rumors and scandals. Many people believe Prime minister Peter Stolypin is the last hope of the Romanov Dynasty as reformer-in-chief. He is horrified by the rise of Rasputin. The fight between Stolypin and Rasputin is a battle for influence over Nicholas II. But Stolypin is shot in the Kiev Opera in 1911.
