- Energy, Ethics and Civilization by Vaclav Smil
- The history of the world joule by joule
Expanded from his book titled Energy in World History, the new book, Energy and Civilization: A History, is a page work providing a panorama of how energy has continually shaped human societies, that is from the dawn of civilization pre-agriculture to our current fossil-fueled, complex, and expansionist world. This book is an extensively updated and expanded version of Smil's Energy in World History Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass.
Energy, Ethics and Civilization by Vaclav Smil
I wait for new Smil books the way some people wait for the next Star Wars movie. In alone, Smil published four! Many impressive writers who come from journalism are the opposite. Smil can do both with equal facility. Yes, our history has a lot to do with kings and queens and games of thrones. Smil shows that it has even more to do with energy innovation. They applied that brainpower to getting even more efficient at converting energy into food—using animal power, tools, crop rotation, fertilizers, irrigation, and new seed varieties.
The history of the world joule by joule
Vaclav Smil, distinguished professor of the University of Manitoba, Canada, has made a career of dissecting broad topics of society from food production, the history of materials to energy. A prolific writer, with more than 40 books published under his belt, his masterpiece recounts the history of civilisation through the lenses of energy: how we've gathered, transformed and consumed energy over the past years. Smil's fundamental thesis stems from developments such as human bipedalism. He argues that human progress has largely been a consequence of our ability to convert energy more and more efficiently. Energy and Civilization is thus the story of the different energy sources and primer movers the engines that transform energy into work that have shaped the past 10, years. And Smil walks us through that history in 3 major phases.
A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today's fossil fuel—driven civilization. In his latest book, Energy and Civilization: A History , he goes deep and broad to explain how innovations in humans' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10, years. Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence.
Smil is a Distinguished Professor at the University of Manitoba. In Alfred Lotka — formulated his law of maximized energy flows: In every instance considered, natural selection will so operate as to increase the total mass of the organic system, to increase the rate of circulation of matter through the system, and to increase the total energy flux through the system so long as there is present and unutilized residue of matter and available energy. The greatest possible flux of useful energy, the maximum power output rather than the highest conversion efficiency thus governs the growth, reproduction, maintenance, and radiation of species and complexification of ecosystems. The physical expression of this tendency is, for example, the successional progression of vegetation communities toward climax ecosystems that maximize their biomass within the given environmental constraints—although many environmental disturbances may prevent an ecosystem from reaching that ideal goal. In the eastern United States, an unusually powerful hurricane may uproot most of the trees before an old-growth forest can maximize its biomass. Human societies are, fundamentally, complex subsystems of the biosphere and hence their evolution also tends to maximize their biomass, their rate of circulation of matter, and hence the total energy flux through the system.
Когда он клал конверт в одну из ячеек, Беккер повернулся, чтобы задать последний вопрос: - Как мне вызвать такси. Консьерж повернул голову и. Но Беккер не слушал, что тот. Он рассчитал все. Рука консьержа только что покинула ячейку под номером 301. Беккер поблагодарил его и быстро зашагал, ища глазами лифт.
