This book gives an extended review of theoretical and observational aspects of neutron star physics. With masses comparable to that of the Sun and radii of about ten kilometres, neutron stars are the densest stars in the Universe. This book describes all layers of neutron stars, from the surface to the core, with the emphasis on their structure and equation of state. Theories of dense matter are reviewed, and used to construct neutron star models. Hypothetical strange quark stars and possible exotic phases in neutron star cores are also discussed. Also covered are the effects of strong magnetic fields in neutron star envelopes and a comparison on neutron star models with observations.

Even to the unaided eye, the sky displays a richness of sights. Stars of different brightnesses and colors spangle the blackness of night. Here and there are pairs and clusters. If the right time of year, a band of white encircles the heavens, the Milky Way, bejewelled with bright stars and stamped with mysterious voids. Binoculars and small telescopes reveal more: the Milky Way is made of countless faint stars, while double stars, clusters, and clouds of swirling gas abound.
Eyewitness Flag
Discover the story of flags and banners -- their history, their meanings and how they are used.
Here is a spectacular and informative guide to the history of flags around the world. Superb color photographs give the reader a unique "eyewitness" insight into the story of flags -- from the earliest heraldic banners to the national flags of today. See the flag of a Chinese pirate ship, the banners of medieval knights and the standards of modern generals, the flags of the French and Russian revolutions, and the national flags of 160 different countries. Learn how to signal by semaphore, how to hoist a flag, why stars and stripes features in the American flag, how flags were hoisted on the Moon and at the South Pole, and how fascinating ceremonies connected with flags have evolved. Discover how Britain's Union Jack has changed over the years, the story behind the Japanese "rising sun," when a flag is flown as half mast, why many Dutch flags feature a picture of a hat on the end of a pole, what the stars on the Australian flag represent, and much, much more!
