Entropy is a measure of order and disorder. If left alone, aging systems go spontaneously from a youthful, low entropy and order, to an old, high entropy and disorder. This book presents the commonality of entropy principles which govern the birth, maturation, and senescent history of aging humans, corporations, and the universe. Mainly, we introduce and entropy theory of aging, based on the non-equilibrium thermodynamic ideas of Ilya Prigogine, leading to the thermodynamic concepts of Excess Entropy (EE) and Excess Entropy Production (EEP).We describe the aging process in humans in terms of the EE and EEP concepts. This book also describes the information entropy theory and equations of Claude Shannon and the six parameters which trace and mark the lifecycle of corporations. To conclude, this volume uses classical and informational entropy concepts, equations and calculations to explain the birth, evolution, and death of our aging universe, and all of this in relation to the concept of Infinity.
