    About this ebook

    The book contains a total of 501 facts which make the reader wonder about our strange but truly fascinating world.

    The success of this book underlines the growing realisation that books now are no longer looked upon something as having necessarily a direct link to classroom and examination—and in consequence, to be shelved when the need is over. With exciting facts from different fields the book stimulates young reader's interest in the world around him-thus inspiring him to pursue knowledge purely for the sake of it.In turn it also helps to develop logical thinking and a scientific temperament.

      PREFACE

      In our daily life, we see or hear from others about many fascinating things. Sometimes, they appeartotally unbelievable. This bookpresents 501 such Astonishing Facts.

      The book has been presented in ten chapters. These highlight the most peculiar aspects of the earth, universe, human body, animals, birds, plants, people, places, science, technology and many others. The book also shows some additional items. Most of the facts have been illustrated fairly well.
