400 Years of the Telescope

A Hole In The Head examines the development of modern trepanation as used by people in the UK, the US, and the Netherlands for the purpose of attaining a higher level of consciousness. This procedure, used by the ancient Egyptians, Incas and others, is believed by the voluntarily trepanned to allow for renewed brain pulsations that increase brain blood volume and thereby improve brain function. Interviews regarding the history and efficacy of the procedure are also held with some of the world's most respected neurosurgeons and anthropologists.

This documentary outlines the unique properties and latest studies of "Physarum Polycephalum", also known as Blob.

Photo sequence of the rare transit of Venus over the face of the Sun, one of the first chronophotographic sequences. In 1873, P.J.C. Janssen, or Pierre Jules César Janssen, invented the Photographic Revolver, which captured a series of images in a row. The device, automatic, produced images in a row without human intervention, being used to serve as photographic evidence of the passage of Venus before the Sun, in 1874.

Before the joint NASA/ESA Cassini-Huygens mission, humanity only knew what had been learned, decades earlier, with the previous limited, rapid "fly-by" Pioneer and Voyager missions. Cassini-Huygens spent more than 13 years in wildly varied orbits around Saturn, allowing the spacecraft to pass near many of its moons, as well as execute a soft-landing of its Huygens lander on the moon Titan. By mission end, it accumulated a mountain of imagery and scientific data that will continue to be studied for years to come. This film is a testament to the amazing efforts of the scientists who planned and executed the mission. It combines breathtaking images, movies, and a variety of animations to take the viewer into Saturn's complex system of rings and moons, as well as stepping viewers through some of the more exciting scientific discoveries made over the course of the elaborately complex mission.
