Influential and respected scientists explain how their unique scientific perspectives have redefined how we think about the world around us

Physicist Professor Andre Geim\'s constant search for new ideas has led to some extraordinary discoveries, from levitating frogs to a tape that sticks to surfaces like a gecko\'s foot. He reveals how his playful approach to his research helped him uncover the properties of graphene, the world\'s thinnest material, and won him a Nobel Prize.

For paleontologist Professor Jenny Clack, who solved one of the greatest mysteries in the history of life on Earth, success was far from inevitable. She recounts how she had to overcome a series of setbacks before she found and described the fossil Acanthostega, a 365 million-year-old creature that offered dramatic new evidence of how fish made the transition onto land.

Professor Richard Dawkins reveals how he came to write his explosive first book The Selfish Gene, a work that was to divide the scientific community and make him the most influential evolutionary biologist of his generation.

Series which tells the story of how people came to understand the natural order of the plant world, and how the quest to discover how plants grow uncovered the secret to life on the planet.

What makes plants grow is a simple enough question. The answer turns out to be one of the most complicated and fascinating stories in science and took over 300 years to unravel.

For 10,000 years or more, humans created new plant varieties for food by trial and error and a touch of serendipity. Then 150 years ago, a new era began. Pioneer botanists unlocked the patterns found in different types of plants and opened the door to a new branch of science - plant genetics. They discovered what controlled the random colours of snapdragon petals and the strange colours found in wild maize.
