J. Robert Oppenheimer was one of the iconic figures of the 20th century, a brilliant physicist who led the effort to build the atomic bomb but later confronted the moral consequences of scientific progress. When he proposed international controls over atomic materials, opposed the development of the hydrogen bomb, and criticized plans for a nuclear war, his ideas were anathema to powerful advocates of a massive nuclear buildup during the anti-Communist hysteria of the early 1950s.

Considered one of the finest historical works in the English language, The Decline and Fall of the Roman Empire is lauded for its graceful, elegant prose style as much as for its epic scope. Remarkably accurate for its day, Gibbon's treatise holds a high place in the history of literature and remains an enduring subject of study.

Gibbon's monumental work traces the history of more than 13 centuries, covering the great events as well as the general historical progression. This first volume covers A.D. 180 to A.D. 395, which includes the establishment of Christianity and the Crusades.

Marx and Engels were right when they observed in the Communist Manifesto that free markets had in a short time created greater prosperity and more technological innovation than all previous generations combined. A century and a half later, all the evidence shows that capitalism has lifted millions and millions from hunger and poverty. Today's story about global capitalism, shared by right-wing and left-wing populists, but also by large sections of the political and economic establishment, does not deny that prosperity has been created, but it says it ended up in far too few hands.

It's no secret that we're pushed to the limit. Today's professionals feel rushed, overwhelmed, and perennially behind. How can we break out of the cycle and create the kind of interesting, meaningful lives that we all seek? Just as CEOs who optimize for quarterly profits often fail to make the strategic investments necessary for long-term growth, the same is true in our own personal and professional lives.

"Correlation does not imply causation". This mantra has been invoked by scientists for decades and has led to a virtual prohibition on causal talk. But today, that taboo is dead. The causal revolution, sparked by Judea Pearl and his colleagues, has cut through a century of confusion and placed causality - the study of cause and effect - on a firm scientific basis.
