On An Inversion Of Ideas As To The Structure Of The Universe is a book written by Osborne Reynolds and published in 1903. The book presents Reynolds' theory that the universe is not expanding, as was commonly believed at the time, but rather contracting. Reynolds argues that this contraction is caused by the gravitational attraction of all matter in the universe towards a central point. He also proposes that the universe is finite in size and that it has a definite shape, which he describes as a ""dumbbell"" shape. Reynolds' theory was controversial at the time of publication, as it contradicted the prevailing view of the universe as an infinite and expanding entity. However, his ideas would later be revisited and expanded upon by other scientists, particularly in the field of cosmology. The book is written in a scientific and technical style, with mathematical equations and diagrams to support Reynolds' arguments. It is aimed at a scholarly audience, particularly those with an interest in physics and astronomy.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
