Modern cosmology and its relationship to the development of human civilization is the subject of this book. Astronomers, cosmologists and historians have contributed fourteen essays covering a wide range of subjects. These include the place of astronomy in China by Joseph Needham, frontiers in cosmology by Fred Hoyle, the dark matter problem by Bernard Carr and the origin of life by Cyril Ponnamperuma. There are also contributions on astrology, science fiction and science.
The determination of stellar ages has been - and still is - crucial for the development of our understanding of the universe, and to constrain theoretical models for the formation of galaxies and the evolution of planetary systems. Stellar ages provide scientists with timescales, and these timescales allow us to identify the relevant physical processes responsible for the development of cosmic structures. This book describes in a simple, yet rigorous, manner the vast array of techniques that have been developed and are currently being used to determine the ages of stars. It also explores how stellar ages inform our knowledge about planets, star clusters, galaxies, even distant galaxies that we cannot resolve into individual stars. Up-to-date with the latest research and technologies in the field, it includes the cutting-edge methods being used based on asteroseismology and discusses open problems that remain to be pondered in future research. It will be of interest to advanced undergraduates and graduate students studying astronomy, in addition to the general public. Key Features Presents an entertaining and accessible approach whilst also providing a rigorous and comprehensive presentation of the subject Describes how to unveil the ages of stellar populations in distant galaxies that we cannot resolve into individual stars Contains historical notes about these techniques, outstanding major problems, and a discussion on future developments in the field

The information explosion of the 20th century has made obsolete all of the beliefs about reality that preceded it. Led by the works of Albert Einstein and R. Buckminster Fuller, this new information also opens up new opportunities and possibilities to create a constitutional global society of peace, prosperity, and environmental purity. Fuller's Global Grid Initiative is introduced as a doable, win-win, planetary project to bring this new society into existence. Fuller proposed the interlinking of renewable energy resources to establish a global energy internet. This system will provide a permanent supply of clean, abundant power to uplift the standard of living for the whole world and to eliminate pollution.
