What makes the modern world work? The answer to this deceptively simple question lies in four "grand transitions" of civilization - in populations, agriculture, energy, and economics - that have transformed the way we live. 

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.

In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today's fossil fuel-driven civilization and offers listeners a magisterial overview of humanity's energy eras.

For millennia, humans have used one simple method to solve problems. Whether it's planting crops, building skyscrapers, developing photographs, or designing the first microchip, all creators follow the same steps to engineer progress. But this powerful method, the "engineering method", is an all but hidden process that few of us have heard of—let alone understand—but that influences every aspect of our lives.

World leaders have promised everything to everyone. But they are failing. The UN’s Sustainable Development Goals are supposed to be delivered by 2030. The goals literally promise everything, like eradicating poverty, hunger and disease; stopping war and climate change, ending corruption, fixing education along with countless other promises.

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely. 

As one of the few black students in his philosophy program at Columbia University years ago, Coleman Hughes wondered why his peers seemed more pessimistic about the state of American race relations than his own grandparents–who lived through segregation. The End of Race Politics is the culmination of his years-long search for an answer.

A collection of essays that discusses such issues as the media, immigration, the minimum wage, and multiculturalism.

In Made in the USA, Vaclav Smil powerfully rebuts the notion that manufacturing is a relic of predigital history and that the loss of American manufacturing is a desirable evolutionary step toward a pure service economy. Smil argues that no advanced economy can prosper without a strong, innovative manufacturing sector and the jobs it creates. Smil assesses various suggestions for solving America's manufacturing crisis, including lowering corporate tax rates, promoting research and development, and improving public education. Will America act to reinvigorate manufacturing?

In a career spanning 60 years, Sir Karl Popper has made some of the most important contributions to the 20th century discussion of science and rationality. The Myth of the Framework is a collection of some of Popper's most important material on this subject.  

Superintelligence asks the questions: What happens when machines surpass humans in general intelligence? Will artificial agents save or destroy us? Nick Bostrom lays the foundation for understanding the future of humanity and intelligent life. The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. If machine brains surpassed human brains in general intelligence, then this new superintelligence could become extremely powerful - possibly beyond our control.

Whether complete or only fragmentary, the 930 extant Dead Sea Scrolls irrevocably altered how we look at and understand the foundations of faith and religious practice. Now you can get a comprehensive introduction to this unique series of archaeological documents, and to scholars' evolving understanding of their authorship and significance, with these 24 lectures. Learn what the scrolls are, what they contain, and how the insights they offered into religious and ancient history came into focus.

The quest for social justice is a powerful crusade of our time, with an appeal to many different people, for many different reasons. But those who use the same words do not always present the same meanings. Clarifying those meanings is the first step toward finding out what we agree on and disagree on. From there, it is largely a question of what the facts are. Social Justice Fallacies reveals how many things that are thought to be true simply cannot stand up to documented facts, which are often the opposite of what is widely believed.

In The World for Sale, two leading journalists lift the lid on one of the least scrutinised corners of the economy: the workings of the billionaire commodity traders who buy, hoard and sell the earth's resources. It is the story of how a handful of swashbuckling businessmen became indispensable cogs in global markets: enabling an enormous expansion in international trade and connecting resource-rich countries - no matter how corrupt or war-torn - with the world's financial centres.
