Explore these amazing celestial wonders as they zip through space! This book looks at the difference between comets and meteors and their effects on Earth. The physical characteristics of each are identified in detail. This book won’t come crashing down! It’s filled with fun facts that give additional information on this exciting science topic. This book allows students to use observations of the Sun, moon, and stars to describe patterns that can be predicted.

Reading the Skies


Book Description

From the time of Aristotle until the late eighteenth century, meteorology meant the study of "meteors"—spectacular objects in the skies beneath the moon, which included everything from shooting stars to hailstorms. In Reading the Skies, Vladimir Jankovic traces the history of this meteorological tradition in Enlightenment Britain, examining its scientific and cultural significance. Jankovic interweaves classical traditions, folk/popular beliefs and practices, and the increasingly quantitative approaches of urban university men to understanding the wonders of the skies. He places special emphasis on the role that detailed meteorological observations played in natural history and chorography, or local geography; in religious and political debates; and in agriculture. Drawing on a number of archival sources, including correspondence and weather diaries, as well as contemporary pamphlets, tracts, and other printed sources reporting prodigious phenomena in the skies, this book will interest historians of science, Britain, and the environment.




Using Spanish Vocabulary

Thucydides, Pericles, and the Idea of Athens in the Peloponnesian War


Book Description

Thucydides, Pericles, and the Idea of Athens in the Peloponnesian War is the first comprehensive study of Thucydides' presentation of Pericles' radical redefinition of the city of Athens during the Peloponnesian War. Martha Taylor argues that Thucydides subtly critiques Pericles' vision of Athens as a city divorced from the territory of Attica and focused, instead, on the sea and the empire. Thucydides shows that Pericles' reconceputalization of the city led the Athenians both to Melos and to Sicily. Toward the end of his work, Thucydides demonstrates that flexible thinking about the city exacerbated the Athenians' civil war. Providing a thorough critique and analysis of Thucydides' neglected book 8, Taylor shows that Thucydides praises political compromise centered around the traditional city in Attica. In doing so, he implicitly censures both Pericles and the Athenian imperial project itself.

Predicen que el futuro del combustible para naves interestelares seran los 'protones energeticos'. Concretan como identificar a los seres humanos 'hibridos' o 'seres especiales' compuestos de ADN ET Y TERRICOLA y a su vez encontrar a los extraterrestres que conviven entre nosotros.

Bloodsucking Witchcraft


Book Description

In the rural areas of south-central Mexico, there are believed to be witches who transform themselves into animals in order to suck the blood from the necks of sleeping infants. This book analyzes beliefs held by the great majority of the population of rural Tlaxcala a generation ago and chronicles its drastic transformation since then. "The most comprehensive statement on this centrally important ethnographic phenomenon in the last forty years. It bears ready comparison with the two great classics, Evans-Pritchard's Witchcraft Among the Azande and Clyde Kluckhohn's Navaho Witchcraft."—Henry H. Selby
