Have you ever seen a comet? It is a marvelous experience, one that all humans can share, that spawns a deep yearning to understand the spectacle. Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce the unique book that you now hold in your hands. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed, in fact, this book doesn't contain a single equation! Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our Solar Systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books! The next Great Comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.


Celtic Literatures in the Twentieth Century Celtic Literatures in the Twentieth Century

«The Centre for Irish and Celtic Studies at the University of Ulster hosted at Coleraine, between the 24th and 26th August 2000, a very successful and informative conference on ‘Celtic Literatures in the Twentieth Century’. The lectures and the discussions were of a high standard, and it was the intention of the organisers to edit and publish the proceedings as soon as possible thereafter. Unfortunately, due to dif culties in assembling some of the papers, this was not possible and, consequently, publication has been delayed much longer than was originally anticipated. Despite this delay, we feel that those papers which we have received merit publication at this time, not only because of their intrinsicmerits, but also because they represent the views of the authors on their respective topics at the turn of the twenty rst century and will hopefully be of value to those interested in the state of the modern Celtic literatures.»

XXI век: исламский вызов. XXI Century: Islamic Challenge XXI век: исламский вызов. XXI Century: Islamic Challenge

Автор: Роберт Енгибарян

Год издания: 

«Исламская цивилизация, в принципе отрицает независимость личности, ее индивидуальные права и свободы, жестко требует от своих приверженцев полного духовного и физического подчинения, восприятия ими ислама в качестве своей человеческой сущности. Реактивный количественный рост исламского населения, подстрекаемый Турцией, Саудовской Аравией, Пакистаном, Катаром и другими, их переселение в дряхлеющие европейские страны, с целью их постепенной исламизации, последние годы особенно усилился. Классическая схема этого процесса выглядит так. Сначала массовая миграция голодных молодых мужчин и женщин, детей, потом их консолидация вокруг мечетей, исламских школ и медресе, бурный количественный рост в новых в значительно более благоприятных условиях, обособленная жизнь в своих анклавах на средства, выделенные государством в качестве социальной помощи и строительство, посланные Турцией, Саудовской Аравией, Катаром и другими деньги, новых мечетей, натурализация и приобретение гражданства, создание подручной пятой колонны и политических партий, бесконечные стычки и требования для живущих по шариату неработающих мусульман новых социальных благ…»
