Go-To Telescopes Under Suburban Skies is the first book specifically written for amateur astronomers who own, or who are about to purchase, a computer-controlled ‘go-to’ telescope. Computer control and automatic location of objects in the night sky is now a feature of even inexpensive astronomical telescopes (under $200), no longer just of the more expensive models. The advantage of the ‘go-to’ capability is enormous – the telescope can be aimed at any object in the sky with great speed and accuracy – and so is the popularity of these instruments. GO-TO Telescopes Under Suburban Skies provides literally hundreds more targets beyond those offered by the built-in ‘nightly tours’ that feature on the telescope’s computer handset (a feature incorporated by most manufacturers). Although most ‘go-to’ telescopes have enormous databases of objects they can find – usually running into tens of thousands – the tours (that’s suggested objects to look at) are always very limited. Once you’ve seen the planets and bright objects that the computer suggests, you’re on your own…

"The Gothic Cathedral is the most stimulating and comprehensive work on the subject to date. . . . If the cathedrals are to be understood, Mr. von Simson rightly declares, they must be seen not in the light of twentieth-century esthetic observation, but of twelfth-century religious experience, through which the supernatural permeated every aspect of human existence. . . . The resulting interpretation of the monuments is a critical tour de force."--Allan Temko, The New York Times Book Review "Not since Mont-St.-Michel and Chartres has so poetic and so evocative a study of the Gothic movement been published. . . . The Gothic Cathedral is based on a wide factual as well as intuitive knowledge, transformed by the author's illuminating style into a text both formidable and pleasurable."--The Virginia Quarterly Review

Ichthyosaurs and plesiosaurs and mosasaurs, oh, my! The prehistoric oceans and shallow seas that covered most of present-day North America and Europe were rife with such now-extinct monsters. They evolved from land reptiles that returned to the water, but they didn't all coexist: the ichthyosaurs, looking a lot like dolphins and most docile of the group, first appeared about 250 million years ago, followed by the plesiosaurs, which looked like swimming velociraptors; pliosaurs, first cousins to the plesiosaurs and able to take on a shark bigger than a great white; and finally the mosasaurs, almost 60 feet in length. Pliosaurs and mosasaurs went extinct at the same time as the last terrestrial dinosaurs, 65 million years ago. Acclaimed illustrator and author Ellis (The Empty Ocean) conducts an exhaustive and generously illustrated survey of what paleontologists know about these monsters of the deep. Many species are known only from a partial skeleton or two, so many questions remain, such as, how did they propel themselves though the water (some scientists guess that plesiosaurs propelled themselves like penguins or dolphins) and what does the gravel found near some fossils mean (perhaps the sea dragons used it for ballast, like modern-day crocodiles, or perhaps they used it in gizzard-like structures, like the chicken). One of the biggest unanswered questions about dinosaurs is what their skin looked like, but Ellis applies his imagination and extensive knowledge of maritime animals skillfully in the grayscale drawings that bring these creatures back to life. Casual dinosaur fans may find the dense detail tough going, but die-hard Jurassic buffs will want this for their collections.

Shah 'Abbas I was one of Iran's most influential leaders. Combining his ruthless ambition with a desire for stability, he left a far-reaching mark on the society and artistic heritage of Iran, renovating the country's spectacular shrines and transforming its trading relations with the rest of the world. This richly illustrated book brings together an amazing array of treasures that were given to Iran's shrines during Shah 'Abbas's reign. It traces the story of the Safavid dynasty (1501-1722), a period of dynamic religious and political development in Iran. Art and architecture flourished and achieved new heights of beauty and brilliance with the creation of the magnificent shrines at Ardabil, Mashhad and Qum. During this so-called Golden Age of Persian art, Shah 'Abbas renovated these shrines and donated to them priceless works of art including sumptuous carpets, silks, porcelain and albums, many of which are illustrated here in glorious detail. He also created the new capital at Isfahan his crowning artistic achievement where he rebuilt his empire surrounded by an inner circle of great artists and thinkers. From here he encouraged foreigners to come to Iran and welcomed the opportunity to open up trading links with Europe. This fascinating book looks in detail at this turning-point in Iran's history. It investigates the context of Shah Abbass gifts and renovations; it also explores how these shrines functioned in the early seventeenth century and the ways in which practices and beliefs initiated under the Safavids are reflected in the world-famous shrines at Mashhad and Qum of today.

This beautifully illustrated book describes the birth and evolution of the theory of stellar structure through the vehement controversy between biology (as presented by Darwin) and physics (as presented by Kelvin) about the age of the Earth, which culminated with Rutherford suggesting radioactive dating. Shaviv analyzes critically many proclaimed scientific results, showing how and why they were wrong, and explains why it took decades to find the now accepted scientific answers - where there are such - and why there remains much more to be done before we can say we fully understand what happens up there in the heavens. The Life of the Stars pres fascinating reading for all those interested in the stars, in the history of astronomy and in what their story tells us about how science progresses. Moreover, it will bring readers up-to-date on current problems in astrophysics.

If you can't get to Egypt anytime soon, take John McDonald's informative tour of beloved Queen Nefertari's tomb, which has only been open to the public since 1995. The beautifully structured House of Eternity is replete with full-color photographs of the contrasting desert landscape, the elaborate tomb, and the paintings. Included are explanations of the hieroglyphs and artwork, plus interesting snippets from Nefertari's culture. For example, the queen's own status wasn't enough to make her powerful in the afterlife. The magical chapter 17 from the Egyptian Book of the Dead contains a spell that is painted on Nefertari's tomb walls to assure her transformation from playing senet, to becoming a "ba" bird, then finally worshipping a lion-headed god. To ensure success, the spell ends right at the doorway that marks the burial chamber. Most souls were believed to experience the judgment of Osiris--not so with Nefertari, whose tomb contains no mention of this trial. In fact, most of the gods seem to be greeting Nefertari and urging her through the many passages to Necropolis, the city of the dead. Although the annexes are not open to the public, McDonald has included a photograph and discussion of the only evidence of Nefertari in mummified form.
