The Theory of Spectra and Atomic Constitution: Three Essays Details

Niels Bohr (1885–1962) was a Danish physicist who played a key role in the development of atomic theory and quantum mechanics, he was awarded the Nobel Prize for Physics in 1922. First published in 1924, this second edition of a 1922 original contains three essays by Bohr dealing with the application of quantum theory to problems of atomic structure: the first essay is on the spectrum of hydrogen; the second is on the series spectra of the elements; the third is on the structure of the atom and the physical and chemical properties of the elements. The essays do not aim at a comprehensive treatment of their subjects, instead providing the reader with a more accessible, generalised viewpoint. This book will be of value to anyone with an interest in Bohr's contribution to physics.

Global Turning Points: Understanding the Challenges for Business in the 21st Century Details

The twenty-first century is replete with uncertainty and complexity: game-changing events and trends are transforming the world beyond recognition. For the first time in human history more people live in cities than in the countryside and greater numbers suffer from obesity than from hunger. Emerging economies now represent half of the global economy and during the next few decades India will be the biggest country in terms of population, China the largest in output and the United States the richest among the major economies on a per capita income basis. Food and water shortages will likely become humankind's most important challenge. In this accessible introduction, Mauro Guillén and Emilio Ontiveros deploy the tools of economics, sociology and political science to provide an analytical perspective on both the problems and opportunities facing business in the modern world.
