Now, in celebration of the 100th anniversary of Einstein’s achievement, discover the inside story of Einstein’s masterpiece". The story begins with the intuitive thought experiments that set Einstein off on his quest and traces the revolution in cosmology that is still playing out in today’s labs and observatories. Discover the simple but powerful ideas at the heart of relativity, illuminating the theory—and Einstein’s brilliance—as never before. From the first spark of an idea to the discovery of the expanding universe, the Big Bang, black holes, and dark energy, NOVA uncovers the inspired insights and brilliant breakthroughs of “the perfect theory.”

What was the Wehrmacht? A group of obedient yeasayers? A murdering band of thugs? An army of millions of abused young men? This series in 5 parts provides differentiated and conclusive answers based on the latest historical and comprehensive investigative research, bringing many new facts to light – among them documents proving for the first time ever, what many among the officers actually thought. Blitzkrieg, the lightning war, in German incorporate modern weapons and vehicles as a method to help avoid the stalemate of trench warfare and linear warfare in future conflicts. The first practical implementations of these concepts coupled with modern technology were instituted by the Wehrmacht in the opening theatres of World War II. The strategy was particularly effective to Germany in the invasions of Western Europe and initial operations in the Soviet Union. These operations were dependent on surprise penetrations, general enemy unpreparedness and an inability to react swiftly enough to German offensive operations.

Facebook is a company that has grown from nothing to be worth half a trillion dollars in just 15 years. Today nearly a third of all humans are using it, and yet we rarely get to see the people actually in charge of the biggest social network in the world.
The company has suffered a series of deepening scandals and intense media scrutiny. In 2018, their mission - to connect everyone on the planet - seemed to be going dramatically wrong. Data leaks, fake news and hacks on user security were threatening to destroy everything Mark Zuckerberg had built.
Yet throughout this difficult time, the company allowed the filmakers to follow key members of the team trying to fix the problems and secure the platform. This film goes behind the scenes and follows the teams inside Facebook. It tackles difficult questions, like how our data is used and what content should and shouldn’t be on the site, but also shows how Facebook works, what the teams are doing to secure it, and reveals a hidden technological playground, where some of the smartest engineers in the world are being hired to build systems and technology no one has built before.

Human Planet is a majestic portrait of humankind and the power of nature in extraordinary symbiosis, struggle and strife. For the first time, the camera has turned on ourselves. In doing so, we see how amazing human beings can be and how we adapt to any habitat, anywhere. Human Planet is epic in ambition, extreme in content, intimate in effect. It explores how we have devised ways of surviving in every corner of Earth – from the remotest deserts to the busiest urban metropolis. Each episode focuses on an iconic environment and reveals how we have adapted to the challenges of the landscape and the endless diversity of animals and plants we live with. Discover how our remarkable intelligence, tool use, and close-knit social lives have enabled us to cope with just about anything nature can throw at us". As an air-breathing animal, the human is not built to survive in water. But people have found ways to live an almost aquatic life so they can exploit the sea's riches. From a 'shark-whisperer' in the Pacific to Brazilian fishermen collaborating with dolphins to catch mullet, this journey into the blue reveals astonishing tales of ingenuity and bravery. Daredevil Galician barnacle-collectors defy death on the rocks for a catch worth 200 pounds per kilo. In Indonesia an epic whale-hunt, using traditional hand-made boats and harpoons, brings in a sperm whale. The Bajau 'sea gypsies' of the Sulu Sea spend so much time on water they get 'land sick' when they set foot on the land! We dive 40 metres down to the dangerous world of the Pa-aling fishermen, where dozens of young men, breathing air through a tangled web of pipes attached to a diesel engine, capture thousands of fish in a vast net. We see how surfing has its origins in the ancient beliefs of the ocean-loving Polynesians, and we join a Borneo free-diving spear-fisherman on a breath-taking journey 20 metres down in search of supper.

Long ago, two species of human beings coexisted on Earth until competition drove one of them to extinction. This program, set in the southwest of France 35,000 years ago, reconstructs the life in the Neanderthal world at the time Cro-Magnons first entered the scene. All aspects of Neanderthal clan life are examined, including tool- and weapon-making, hunting and gathering, health and healing, childbirth, rituals, and making fire. Footage of skeletal remains and the scholarly research of eminent paleontologist Chris Stringer and Oxford University's Paul Pettitt support the documentary.

Could time travel ever be science fact? Time itself may be something you can bend and stretch. Trying to understand if time travel can be possible teach us a lot about the universe. It forces us to take on some of the toughest unanswered questions in all of physics and will ultimately probably lead to deeper understanding of the very nature of the cosmos.
