In this book, you will find the first alternative and physically based calculation of gravitation since Newton`s formula (1687). This new theory offers the possibility to consider the shape, position, movement, and environment on the gravitational effect of the masses. The contents of this book will have consequences in astronomy, geology, climatology, as well as other physical sciences such as light, capillarity, diffusion etc. The presented theory deserves to be further researched and developed. The author (1943) came to Germany after graduating from high school (1961) in Istanbul, studied mechanical engineering in Karlsruhe (KIT), where he also worked in industrial research and development until 2010. During this time, he lectured at the Universities of Karlsruhe and Kaiserslautern while researcing gravitation as a hobby. That is why he writes in such a way that it should be understandable, verifiable, calculable and applicable for laypersons as well as specialists. Bedrettin Dalan, founder and director of the ISTEK Foundation and Yeditepe University in Istanbul, stayed in Germany for a number of years. In his discussions with the author, who was a close friend, he recognized the importance of his thesis and prompted him to write about it. He also made it possible for this book to be published by his university`s publishing house. Without his commitment this book would not have been possible.
