This is the story of a book that could have changed the history of the World. To the untrained eye, it is nothing more than a small and unassuming Byzantine prayer book. For faintly visible beneath the prayers on its pages are other, unique, writings - words that have been lost for nearly two thousand years. The text is the only record of work by one of the world's greatest minds - the ancient Greek, Archimedes - a mathematical genius centuries ahead of his time. Hidden for a millennium in a middle eastern library, it has been written over, broken up, painted on, cut up and re-glued. But in the nick of time scientists have saved the precious, fragile document, and for the first time it is revealing just how revolutionary Archimedes' ideas were. If it had been available to scholars during the Renaissance, we might have reached the Moon over a hundred years ago.

The 8th episode reviews Giovanni Cassini's life. His observations of Saturn and its moons would have an enduring effect on the scientific world. Neil deGrasse Tyson also narrates the mysterious untold story of the scientist who figured out how to go the Moon while fighting for his life in a WWI trench. Aleksandr Shargei changed his name to Yuri Kondratyuk out of fear for his life and wrote a manuscript on rocket motion and space colonization. This letter would end up capturing the attention of an engineer working on the Apollo program, John Houbolt, and would made the Apollo Mission possible.
We will also know the saga of the twenty-year long odyssey of Cassini-Huygens spacecraft, a robotic explorer ordered to commit suicide on another world.

Included acustic versions and interviews. The most phenomenal recording in rock & roll history: The Dark Side of the Moon. The Floyd's 1973 masterpiece remained on bestseller charts for nearly 14 years, and its enduring importance is honored here by all four members of Pink Floyd and key personnel (engineer Alan Parsons, mixing supervisor Chris Thomas, sleeve designer Storm Thorgerson, and others) who played essential roles in the landmark album's creation.

Earth’s oceans help make our planet different from every other planet in the solar system. As far as we know, no other place is the right temp for liquid water, the most essential ingredient for life to exist. The oceans are Earth’s primary stabilizing force, and their immense power helps to shape the appearance and behavior of the entire planet and everything living on it. And they are also the planet's great unknown - their deepest points have been visited less than the surface of the moon.
