KNOWING THE UNKNOWN - III Challenges of Techlogy Past, Present, and Future In this third book in the series on Kwing the Unkwn, we address the question, 'What am I doing?' The book provides a unique perspective on the origin of techlogy, its development, frontiers, and its future. The reader embarks on an exciting journey, which unfolds the mysteries of techlogy in simple terms, as we visit: * Origin and evolution of techlogy & machines * Communication, computers, & control Tech * Health related and genetic-based techlogy * Modern Tech: Intelligent computers, robots * Frontiers & future of techlogy * Top ten challenges This book is meant for any reader interested in techlogy. This is t just ather book on techlogy. It integrates various techlogical developments derived from different scientific concepts. It explains various techlogies in simple terms. It also takes an objective look at how techlogy has changed our lives. This book will heighten readers' interest in techlogy. It will also motivate and encourage young scientists and engineers to seek new techlogy. Finally, it can serve as a textbook for students of the history of techlogy. We take the reader on an exciting journey that unfolds the mysteries of techlogy. During this journey, we visit and cross various milestones in the history of techlogy that have changed our lives forever. We start with the development of machines from the laws of mechanics discovered by Newton, heat engines from the laws of thermodynamics, and wireless communications from the laws governing electro-magnetic phemena unified by Maxwell. This takes us to the discussion of modern communication systems, internet, and GPS and mobile phones, etc. Next, We visit with energy conversion techlogy, and discuss various resources available for energy conversion. These sources include chemical, thermal, hydro, nuclear, solar, hydrogen fuel cell, wind, tidal, geothermal, and biomass. Then, we visit other areas of techlogy, lasers, integrated circuit chips, superconductors, and natechlogy, etc., which are based on modern physics. As we move on, we visit control techlogy. The development of this techlogy was essential to control our environment, control the energy sources, control industrial plants, develop new materials, increase productivity, navigate, and send satellites into space. Next, we visit computer techlogy, based on computer science and solid-state physics, which has ushered in a revolution in techlogy and brought us at the threshold of amplifying our intellectual capabilities. We also visit health care techlogy, developed to help us live healthier and longer lives. We then discuss new challenges for techlogy, and list the top ten challenges. We conclude our journey by discussing the frontiers and the future of techlogy.
