In this book, the author, Dr. Malcolm Bear, chose to address various topics about exploration, the search for the unknown, and the struggle between man and nature in learning its secrets. He tells us about the story of the North and South Poles and the heroes who began to make their way to them in places covered with ice and above which the wind whistled, turning into a fierce smelt penetrating the bones, and how man triumphed in the end and reached these poles at the hands of the Rosses and Amundsens, and about the pioneers who roamed the wilderness of Africa such as Mungo Park, Livingstone and others, then what Picard did when he ascended to the upper layers of the atmosphere exposing himself to the explosion, and what William did. Pei has to reach three thousand feet under the sea's surface to live with the fish of the deep.
