Energy, Entropy, and the Flow of Nature is an attempt to present the essential principles of energetics (thermodynamics) in a manner that is straight-forward, easy to understand, and logically consistent. It arises from the difficulties author Thomas F. Sherman has seen or experienced as a student of physical chemistry, as a teacher of biochemistry and biology, and as a colleague. The central message of the book is that all natural change can be understood as a flow across a gradient, and that part of the effect of every flow is to diminish its own gradient. The book's mission is to build understanding of the central concepts, and with understanding, a degree of confidence in going forth into the many directions that the study of energy opens up. The laws of energy and entropy can indeed, in their applications, become a very complicated subject involving multivariable calculus, differential equations, and challenging problems and calculations. The fundamentals of energetics should be very straightforward, requiring relatively little mathematics--and it is the fundamentals that this book focuses on.

A fresh and unified exploration of the laws that govern natural change, examining the historical roots and meaning of the concepts of energy and entropy. All natural processes--mechanical, thermal, chemical, electrical, and biological--are viewed as a flow across free energy gradients that interact with one another.

This is a sequel to the author’s book entitled “Entropy Demystified.” The aim is essentially the same as that of the previous book by the author: to present Entropy and the Second Law as simple, meaningful and comprehensible concepts. In addition, this book presents a series of “experiments” which are designed to help the reader discover entropy and the Second Law. While doing the experiments, the reader will encounter no unexpected results, and concepts of entropy and the Second Law will emerge naturally from these experiments without a tinge of mystery. These concepts are explained with the help of a few familiar ideas of probability and a 20-question game. The main “value” of the book is to introduce entropy and the Second Law in simple language which renders it accessible to any reader who can read and is curious about the basic laws of nature. The book is addressed to anyone interested in science and in understanding natural phenomenon. It will give the reader the opportunity to discover one of the most fundamental laws of physics — a law that has resisted complete understanding for over a century. The book is also designed to be enjoyable. There is no other book of its kind (except “Entropy Demystified” by the same author) that offers the reader a unique opportunity to discover one of the most profound laws — sometimes viewed as a mysterious law — without the tinge mystery. There are no pre-requisites expected of the readers; all that the reader is expected to do is to follow the experiments or imagine doing the experiments and reach the inevitable conclusions.

Every day brings a fresh barrage of bewildering claims about science and technology. How non-scientists tell the difference between the hyperbole and those developments that are important? With a modest amount of critical thinking, an understanding of how science is practiced, and a qualitative understanding of the two most sacred principles in science - the first and second laws of thermodynamics - anyone can make the distinction. Critical thinking and the practice of science are not emphasized in undergraduate science courses for non-scientists, while exposure to the first and second laws is usually reserved for physical science and engineering majors. This book introduces non-scientists to these topics and provides detailed applications to a variety of topics.

In an age of climate catastrophes and extinction, we need to turn back to nature and learn, once again, how to live sustainably on planet Earth—beginning with our relationship to food. Four billion years ago, Earth was a hot, lifeless planet. Through the process of evolution, the Earth and its diversity of living organisms gradually reduced the amount of carbon in the atmosphere. About 200,000 years ago, the conditions aligned for our own species—Homo sapiens—to emerge and thrive. But what will it take to continue to survive? In The Nature of Nature, world-renowned environmental thinker and activist Vandana Shiva argues that food is the currency of life, a thread woven throughout the web of all life, indivisible from Earth and its natural systems. When this interdependence is ruptured—as it is now—the conditions for the “metabolic disorder” of climate change and countless other ecological imbalances come into being. Proposals put forward by Big Ag and Big Tech to solve the intertwined climate and food crises will only exacerbate both. With clarity and a detailed analysis, Shiva unpacks the false promises made by technology-oriented, lab-intensive digital agriculture, revealing the dangers posed by fake and ultra-processed foods—dangers to the environment, to increasing greenhouse gas emissions, to the health of animals, and to our health and food security. In The Nature of Nature, Shiva takes a powerful stand, arguing with urgency and passion for a food and climate future based not on techno-optimism, hallucination, and corporate delusions, but on the natural regeneration of biodiversity in partnership with the biosphere. Praise for Vandana Shiva: “She’s been called the ‘Gandhi of grain,’ the ‘rock star’ of the anti-GMO movement and an ‘eco-warrior goddess.’ . . . Above all, [she] is a staunch believer that the food we eat matters. It makes us who we are, physically, culturally and spiritually.”—BBC

For the first time Entropy has been completely revised and updated to include a new subtitle which reflects the expanded focus on the greenhouse effect--the largest crisis ever to face mankind.

Environmental issues are of fundamental importance, and a broad approach to understanding the relationship of the human economy and the natural world is essential. In a rapidly changing policy and scientific context, this new edition of Environmental and Natural Resource Economics reflects an updated perspective on modern environmental topics. Now in its fourth edition, this book includes new material on climate change, the cost-competitiveness of renewable energy, global environmental trends, and sustainable economies. The text provides a balanced treatment of both standard environmental economics and ecological economics, based on the belief that these two approaches are complementary. Several chapters focus on the core concepts of environmental economics, including the theory of externalities, the management of public goods, the allocation of resources across time, environmental valuation, and cost-benefit analysis. Material on ecological economics includes such topics as macroeconomic scale, entropy, and "green" national accounting. Topical chapters focus on: energy; climate change; water resources; international trade; forests; fisheries; and agriculture, with an emphasis on designing effective policies to promote sustainability and a "green" economy. Harris and Roach’s premise is that a pluralistic approach is essential to understand the complex nexus between the economy and the environment. This perspective, combined with its emphasis on real-world policies, is particularly appealing to both instructors and students. This is the ideal text for classes on environmental, natural resource, and ecological economics.

The book defends that there is both teleological order (design) and chance in non-living and in living systems of nature including man. This is done by giving exact definitions of different types of order and teleological order on the one hand and of different types of chance on the other. For their compatibility it is important to notice that any definition of chance presupposes some kind of order relative to that we can speak of chance. Thus also in evolution which is some growth of some order and for which a detailed definition is given in chpt.13 chance and degrees of freedom play an essential role. A further purpose of the book is to show that both the existing order and the existing chance in nature are compatible with a global teleological plan which is God’s providence. However concerning the execution of God’s plan not everything is done or caused by himself but “God created things in such a way that they themselves can create something” (Gödel, MAX PHIL). A reason for that is that God is neither all-causing nor all-willing although he is almighty. This is connected with the result of chpts.15 and 16 that also human freedom and evil are compatible with God’s providence.

Originally published in 1975, yet prophetic in its wisdom this book deals with major aspects of man’s ecological destruction in an industrial framework. As well as discussing the destruction of forests by early civilizations the book examines the rate and extension of environmental deterioration in more recent times and the importance of the integrated ‘feed-back’ controls which maintain stability in the ecosphere of which humankind forms a part. Examining the role of entropy, energy quanta and indeterminacy in overthrowing both science and economic theory, the book provides examples from the 20th Century of the uncontrolled demands for energy and material resources, as well as of increasing toxic hazard in the biosphere.
