NOVA Season 24, Episode 21: Kingdom of the Seahorse

Einstein Revealed

This two-hour program chronicles Albert Einstein's life and scientific achievements from his birth in 1879 to his death in 1955. The first hour follows Einstein in his quest to understand the nature of light. Graphics depict some of Einstein's famous thought experiments, including his eventual understanding of the interplay between the speed of light and time and his development of the special theory of relativity. The program also goes into great depth about Einstein's personal life, including his romance with and marriage to fellow student Mileva Maric and the death of his father. The second hour unfolds with Einstein preoccupied with finding a theory that accounts for gravitation and determining what orders the universe. Einstein addresses gravitation in the universe with his general theory of relativity. This is confirmed experimentally in 1919 when a solar eclipse reveals stars in positions that could best be explained by his theory: that gravity causes light to bend.

Three Men and a Balloon

One of the final aeronautics challenges left in the world today does not involve the use of a plane, a rocket, or even an engine. No one has yet been able to circumnavigate the earth in a balloon. Any team attempting the feat would have to fly higher than most planes ever fly and would need a passenger capsule that could both offer protection from extreme cold and carry the proper navigation and life support equipment. Depending on the powerful jet stream to propel them, crew members would have to plot their course carefully and plan their schedule to coincide with the most advantageous winds. Even landing would be a risky venture. This program follows a team of three adventurers as they attempt to make just such a journey.

Secrets of Lost Empires: Stonehenge (1)

Secrets of Lost Empires: Inca (2)

Even without such technological advances as wheels, arches, draft animals, iron tools, or a system of writing, the Inca—utilizing a tradition of shared labor—achieved a number of engineering feats. The NOVA team explores both stonework and bridge building, experimenting with dragging and fitting huge stones, and working with the people of an Andean village to create a suspension bridge made only of grass ropes.

Secrets of Lost Empires: Obelisk (3)

Pharaohs who built magnificent temples to preserve their names for eternity often graced temple gates with pairs of obelisks, four-sided shafts of granite that taper gently upward until the sides meet at the top to form a pyramid shape. NOVA's team of experts attempts to build, transport, and raise a scale model obelisk using those materials available to ancient Egyptian engineers: rope, dirt, sticks, and stones.
