How Do We Know The Nature Of Energy

Explains what energy is, how it is used, and the scientists who studied it.

Gain a fresh perspective using the energies around you Have you ever walked into a room and felt like you wanted to leave right away? Ever met a person for whom you had an instant dislike for no apparent reason? Been around certain people and suddenly feel exhausted? People, animals, situations, objects, and environments contain and give off energy. The energies within and around you can be a major source of anxiety. To discover how to observe, interpret, and direct this abundant energy is to harness the power at your fingertips and create tranquility in your life. This book can guide you in that discovery. In "The True Nature of Energy," you will: Improve your relationship with yourself and others Remove unnecessary emotions and see more objectively Attract the right people and circumstances Clear old, outmoded energies from your life Increase self-trust, self-esteem, and self-confidence Learn to sense and direct the energies around you Enhance your natural intuitive ability Find out your vibrational level by taking the Wing Vibrational Scale Quiz Learn simple techniques to fully take charge of your life and your destiny.

Introduces energy, examines early experiments in harnessing energy, and discusses how it is used today.

Energy is crucial for events of every kind, in this world or any other. Without energy, nothing would ever happen. Nothing would move and there would be no life. The sun wouldn't shine, winds wouldn't blow, rivers wouldn't flow, trees wouldn't grow, birds wouldn't fly, and fish wouldn't swim; indeed no material object, living or dead, could even exist. In spite of all this, energy is seldom considered a part of what we call "nature." In The Energy of Nature, E. C. Pielou explores energy's role in nature—how and where it originates, what it does, and what becomes of it. Drawing on a wide range of scientific disciplines, from physics, chemistry, and biology to all the earth sciences, as well as on her own lifelong experience as a naturalist, Pielou opens our eyes to the myriad ways energy and its transfer affect the earth and its inhabitants. Along the way we learn how energy is delivered to the earth from the sun; how it causes weather, winds, and tides; how it shapes the earth through mountain building and erosion; how it is captured and used by living things; how it is stored in chemical bonds; how nuclear energy is released; how it heats the unseen depths of the planet and is explosively revealed in the turmoil of earthquakes and volcanoes; how energy manifests itself in magnetism and electromagnetic waves; how we harness it to fuel human societies; and much more. Filled with fascinating information and and helpful illustrations (hand drawn by the author), The Energy of Nature is fun, readable, and instructive. Science buffs of all ages will be delighted. “A luminous, inquiring, and thoughtful exploration of Earth’s energetics.”—Jocylyn McDowell, Discovery

The first systematic, quantitative appraisal of power density, offering detailed reviews of power densities of renewable energy flows, fossil fuels, and all common energy uses. “There's no author whose books I look forward to more than Vaclav Smil.” —Bill Gates In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses. Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel–based energy system with renewable energy conversions. Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable (and desirable) move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society—currently dominated by megacities and concentrated industrial production—to undergo a profound spatial restructuring of its energy system.

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.
