By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like an perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems. Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more bizarre. In an infinite universe, there are infinitely many copies of the Earth and infinitely many copies of you. Older than time, bigger than the universe and stranger than fiction. This is the story of infinity.

(Click CC for subtitles) Ranjit, a farmer in India, takes on the fight of his life when he demands justice for his 13-year-old daughter, the victim of a brutal gang rape. His decision to support his daughter is virtually unheard of, and his journey unprecedented. Nominated for Best Documentary Award, the film has an undeniable and unshakable power. It is one of those documentaries where anyone who watches it won’t be the same person by the end as they were when it started.
To Kill a Tiger offers the viewer remarkable access to village life, not just in the modest home where Ranjit’s family make roti on an open fire, but in the fields where they herd goats and collect water from a pump. The camera finds quiet details, like Ranjit’s daughter carefully weaving ribbons into her hair. Women and men insist that the community, not the criminal court, should solve the issue with a forced marriage—to remove the ‘stain on her’. The men become increasingly hostile—to the family, and eventually to the film crew itself.

An extraordinary journey to the top of the world, the documentary adventure tells the ultimate tale of survival. The film takes audiences on a never-before-experienced journey into the lives of a mother polar bear and her twin seven-month-old cubs as they navigate the changing Arctic wilderness they call home. Captivating, adventurous and intimate footage brings moviegoers up close and personal with this family's struggle to survive in a frigid environment of melting ice, immense glaciers, spectacular waterfalls, and majestic snow-bound peaks.

The determination of the German forces to keep on fighting in the face of defeat had disastrous consequences. After the Allied landings in the summer of 1944, the Wehrmacht was on the defensive on all fronts. It was clear to the German generals interned at Trent Park that Germany would soon lose the war. In mid-1944, Gerhard Graf von Schwerin chose to use common sense instead of blindly obeying Hitler's orders. He decided to surrender the city of Aachen to the US army to avoid bloodshed. Other commanders such as Field Marshal Ferdinand Schorner kept on pushing their soldiers to give their all. Despite being outnumbered by the Soviet forces, Schorner forced his soldiers to hold out in Sworbe, a 200 square kilometre peninsula on the coast of Estonia. Thousands of soldiers died. Yet Schorner's attitude and the urging by Hitler and Goebbels to hold out were accepted by a large number of young soldiers. By April 1944, the Ruhr pocket was completely surrounded, yet Field Marshal Model refused to surrender, so that 1.2 million German soldiers and a large number of Allied soldiers died between January and May 1945.

The final leg takes him from the Khyber Pass through Pakistan to the Punjab, where Alexander's army mutinied and he was forced to return across the Makran Desert to Babylon, where he died at only 32 years of age.

We’re going back to the moon. Plans are being made, hardware is being designed, built, and tested to return humans to the moon and beyond in a new era of American space exploration. This episode explores how we did it in the past, and how and why we will do it again. The moon is critical to future explorations: it will be where we learn to build sustainable colonies on other worlds.
