Taking into account the current experimental and technological accomplishments and theoretical methods, this book stresses the basic laws of science, i.e. Archimedes principle, Newton¿s laws, and critically analyses these laws. Generalization of the laws and principle are inevitable. Newton did not discover the Second Law of Motion F = ma. This is is clear from the critical study of the Principia. The 2265 years old Archimedes principle has limitations that it does not take into account the shape of the body and the viscosity of the medium under consideration. The Archimedes principle predicts that the volume of the medium filling a floating balloon/vessel becomes indeterminate, i.

e. 0/0.These are serious limitations of the principle. Archimedes principle is generalized (up thrust weight of fluid displaced), the generalized form takes all elusive factors in account. In the existing literature there is no quantitative theory which may explain the phenomena of rising, falling and floating bodies quantitatively. Such a theory is described in the book for first time.
