25 Discoveries that Changed our World takes you on a journey through some of the greatest breakthroughs in the history of science; discoveries that have changed mankind's perception of where we all come from and why we are here.

The DVD also contains the first episode from new Discovery Channel TV show, The Big Experiment, which poses the question, "does science have the power to change your life"? Over the course of six weeks, three of Britain's leading scientists make teenagers from a tough London school the focus of a ground-breaking social experiment - to see if a series of incredible scientific experiments can change the way they see the world and explode their misconceptions about science.
