When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine the distance of objects several billion light years away from Earth.

The human race has succeeded in explaining nearly everything in this universe using mathematical formulae. Yet there is one place that remains shrouded in mystery -– black holes. Physicists believe that if they could discover a formula that explains the center of black holes, the last remaining mystery of the universe could finally be unraveled -– how the universe came into being. Their attempts have been mired by unforeseen pitfalls but with the development of superstring theory, physicists have arrived at a formula that could finally end their century-long search. What the formula described was a world beyond our wildest imaginations. This is the incredible story of physicists like Einstein, Hawking and the superstring theorists who have endeavored to solve the mystery of the origin of the universe.

Scientists investigate the way the Sun builds its power -- through fusion -- hoping to find a way to use fusion as a less dangerous and less radioactive waste-producing path to energy than fission. But there are some major difficulties along the way...
