Why did a chemistry professor write a text on a medieval practice from the viewpoint of a practitioner? And why would a chemist for a suntan lotion company take such an interest in that professor and her hobby three and half decades later? Finally, and most important, why did they both vanish and where did they go? That was what Miami Beach private detective Nicholas Pierce was trying to figure out when he realized that it was no coincidence that two police detectives investigating the case had been found dead.

MORE THAN ONE MILLION COPIES IN PRINT • “One of the seminal management books of the past seventy-five years.”—Harvard Business Review This revised edition of the bestselling classic is based on fifteen years of experience in putting Peter Senge’s ideas into practice. As Senge makes clear, in the long run the only sustainable competitive advantage is your organization’s ability to learn faster than the competition. The leadership stories demonstrate the many ways that the core ideas of the Fifth Discipline, many of which seemed radical when first published, have become deeply integrated into people’s ways of seeing the world and their managerial practices. Senge describes how companies can rid themselves of the learning blocks that threaten their productivity and success by adopting the strategies of learning organizations, in which new and expansive patterns of thinking are nurtured, collective aspiration is set free, and people are continually learning how to create the results they truly desire. Mastering the disciplines Senge outlines in the book will: • Reignite the spark of genuine learning driven by people focused on what truly matters to them • Bridge teamwork into macrocreativity • Free you of confining assumptions and mindsets • Teach you to see the forest and the trees • End the struggle between work and personal time This updated edition contains more than one hundred pages of new material based on interviews with dozens of practitioners at companies such as BP, Unilever, Intel, Ford, HP, and Saudi Aramco and organizations such as Roca, Oxfam, and The World Bank.

Will the universe continue to expand forever, reverse its expansion and begin to contract, or reach a delicately poised state where it simply persists forever? The answer depends on the amount and properties of matter in the universe, and that has given rise to one of the great paradoxes of modern cosmology; there is too little visible matter to account for the behaviour we can see. Over 90 percent of the universe consists of 'missing mass' or 'dark matter' - what Lawrence Krauss, in his classic book, termed "the fifth essence". In this new edition of The Fifth Essence, retitled Quintessence after the now widely accepted term for dark matter, Krauss shows how the dark matter problem is now connected with two of the hottest areas in recent cosmology: the fate of the universe and the "cosmological constant." With a new introduction, epilogue and chapter updates, Krauss updates his classic and shares one of the most stunning discoveries of recent years: an antigravity force that explains recent observations of a permanently expanding universe.
