In this epochal book, Immanuel Velikovsky, one of the great scientists of modern times, puts the complete histories of our Earth and of humanity on a new basis. He presents the results of his 10-year-long interdisciplinary research in an easily understandable, even entertaining manner. Inspite - or even because - of the disgraceful hostility, provoked by his theories, this book keeps being of ardent topicality, which in the light of recent scientific research is even growing. Earth in Upheaval - a very exactly investigated and easily understandable book - contains material that completely revolutionizes our view of the history of the earth. For all those who have ever wondered about the evolution of the earth, the formation of mountains and oceans, the origin of coal or fossils, the question of the ice ages and the history of animal and plant species, Earth in Upheaval is a MUST-READ!
