This book, meant for general reading, is based on the logical premise that the most general theory of physics; the, so-called, theory of everything; is "the same" as the most general theory of mathematics, as their logical bases are identical. It paints the history of the development of our concepts in leaps and bounces, while clarifying the distinction between "wrong" and "right" ideas. Physics, which is the "pivotal thinking" of our understanding of the workings of the nature, has many examples of this. Many iconic thinkers; Newton, Boltzmann, Einstein; struggled to discover right ideas. This book pays rich tributes to their vision. It challenges the belief that science can tell us only "how" things happen in the nature and cannot answer as to "why" they happen as they do. This book is for everyone interested in knowing how our scientific ideas have developed, and where the scientific understanding of the nature stands, as of today. Background of physics is not demanded as prerequisite to grasp its contents. For more details, please visit https://centralwestpublishing.com
