Pluto is entrenched in our cultural and emotional view of the cosmos, and Neil deGrasse Tyson, award-winning author and director of the Rose Center, is on a quest to discover why. He stood at the heart of the controversy over Pluto's demotion, and consequently Plutophiles have freely shared their opinions with him, including endless hate mail from third-graders. With his inimitable wit, Tyson delivers a minihistory of planets, describes the oversized characters of the people who study them, and recounts how America's favorite planet was ousted from the cosmic hub.

    A concise look at the impact of the advent of the telescope on the way humans view the universe and their place in it focuses on the visionaries, beginning with Galileo, who created and perfected it.

    However, it is one of the basic principles of quantum theory, the most widely accepted explanation of the subatomic world - and one of the fascinating subjects dealt with in Equations of Eternity.

    Moreover, the achievements of the early people of Africa are as amazing and inspiring as the achievements of any other people.This history is much older than the Trans-Atlantic Slave Trade.The author introduces his readers to the early civilizations of Africa that existed long before the coming of the Europeans. Among these were the Songhai Empire, the Benin Empire, the Kanem-Borno Empire, the Monomotapa Empire, the Swahili Confederation, the Medieval Nubian kingdoms and the Axumite Empire.The author also introduces the ancient civilizations of Africa particularly those of the Nile Valley such as Nubia and Ancient Egypt.The book is illustrated with 18 images and maps. Finally, the book recommends other books for more in depth study.

    Vulcan’s Fury, as the impact event was known, had become a distant but poignant memory of how wrathful the gods can be, and it was the duty of every Roman to see that they were never angered again. Over those many years, the Roman Empire had finally brought to heel the entire known world, save the Dark Lands. Hidden behind a barrier of smoldering volcanoes and the deadly Haunted Sea, the Dark Lands were at the heart of ancient legends among the Romans of terrible beasts, and worse, that had once feasted upon the flesh of men in the earliest days of the First Spring. But ancient legends held no fear for Princess Valeria, daughter of Caesar Tiberius Claudius Augustus. Enthralled by reports of strange happenings along the coast and bored by the life of a young Roman noblewoman, she begs her father to allow her to travel to the coast of the Haunted Sea to indulge her curiosity. Tiberius grants her request, anxious to see her safely away from Rome, where the Senate is plotting against him. Together with her closest companions, including her enormous hexatiger, Hercules, Valeria sets off on her adventure, unaware that she has set in motion a series of events that will change the history of the Empire, and all Humankind, forever…

     At the age of seventeen, he embarks upon his first voyage under sail. Queen Victoria’s empire is growing fast and the good ship Pass of Drumochter is bound for the seven seas to trade the empire’s goods. But the glamour soon falls from Tom’s eyes when he finds himself the unwitting eye witness to a foul murder. There is a stranger on board, and suddenly the harsh waters are no longer the most deadly thing threatening the lives of the ship’s men. Earning his master’s ticket is going to be as much about learning to cope with the terrifying ne’er do wells on board ship as it is about sails and navigation. The first in a series of adventures spanning the sixty year career of an officer in Queen Victoria’s merchant navy, Apprentice to the Sea describes the first steps into a life at sea.

    We were the very first that revolted, and we are the last to fight against them; and I cannot but esteem it as a favor that God has granted us, that it is still in our power to die bravely, and in a state of freedom." - Elazar ben Yair Many Westerners have never even heard of the Siege of Masada, and those who have may simply know it as an obscure reference to a minor battle fought in a remote location of the Roman world. By contrast, virtually all Israeli school children know the story of Masada as a premier example of nationalistic pride. According to historian Klara Palotai, "Masada became a symbol for a heroic 'last stand' for the State of Israel and played a major role for Israel in forging national identity" Indeed, the heroic story of a small band of fighters facing incalculable odds has many elements that are reminiscent of both the Battle of Thermopylae and the Battle of the Alamo. The refrain “Masada shall not fall again,” coined in a poem on the subject by Yitzak Lamdan, became a cry of resolve in battle for Israeli soldiers in the 20th century, just as the cry of “Remember the Alamo” had galvanized Americans. For decades, the Israelite military used the site of Masada as the location for swearing in their new recruits, and the choice of the site was obviously designed to evoke within the new soldiers a deep sense of connection with their national history. The Siege of Masada was the final battle in a long series of fights that constituted the First Jewish-Roman War. The Roman Empire had established control over the region in the 1st century BCE, when the Roman proconsul Pompey the Great took control of Jerusalem and ceremonially defiled their temple by entering it. This mix of political control and religious desecration was a contentious issue for the Judeans throughout the Roman period, and militant activists opposed to Roman rule, often espousing strongly held religious beliefs, frequently developed large followings to challenge the Roman authorities. This led to multiple violent clashes between the Judeans and the Romans, and the First Jewish-Roman War (66-73 CE) was one such clash (albeit on a larger scale than most). The Roman troops marched through and made their military might felt, first in the northern region of Galilee, then down the coast where they finally laid siege to the capital city of Jerusalem. This left three Roman fortress outposts, including Masada, that had been built by Herod the Great but had been taken over by various Judean factions. Masada was the last of these fortresses that the Romans attacked and proved the most difficult for them to seize, but seize it they did. However, what made this battle qualitatively different from most was not just the difficulty Rome had in retaking control of it with incredibly disproportional military equipment and numbers, but also the actions of the Judean defenders. In the final hours of the battle, just as the Romans were about to breach the walls of the city, the defenders gathered together and committed mass suicide, rather than being killed or taken captive by the Romans. The Siege of Masada: A Historical Drama of the Famous Battle Between the Jews and Romans is a historical drama that portrays the famous battle from the standpoint of a fictional survivor.

    Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    They infinitely warp space and time, allowing nothing to escape: not matter, not even light. They are stellar corpses that have crushed themselves into oblivion, seemingly suspending the traditional laws of physics. The Big bang may have peppered the universe with primordial black holes, as small as protons but as massive as mountains. The universe itself may be disappearing into the final black hole. Black holes (BHs) and their warping effect on spacetime are described, beginning with a discussion on stellar evolution that includes white dwarfs, supernovas and neutron stars. The structure of static, rotating, and electrically charged BHs are considered, as well as the general theory of relativity, quantum mechanics, the Einstein-Rosen bridge, and wormholes in spacetime. Attention is also given to gravitational lenses, various space geometries, quasars, Seyfert galaxies, supermassive black holes, the evaporation and particle emission of BHs, and primordial BHs, including their temperature and lifetime. The author's engrossing, non-technical explanations are enhanced by numerous illustrations.

    Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye. The debate culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about.Filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is Mike Brown’s engaging first-person account of the most tumultuous year in modern astronomy—which he inadvertently caused. As it guides readers through important scientific concepts and inspires us to think more deeply about our place in the cosmos, it is also an entertaining and enlightening personal story: While Brown sought to expand our understanding of the vast nature of space, his own life was changed in the most immediate, human ways by love, birth, and death. A heartfelt and personal perspective on the demotion of everyone’s favorite farflung planet, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever dreamed of exploring the universe—and who among us hasn’t?

    Relive key moments in the monumental Hubble story, from launch through major new instrumentation to the promise of discoveries to come. With more than 150 photographs including Hubble All-Stars—the most famous of all the noteworthy images—The Hubble Cosmos shows how this telescope is revolutionizing our understanding of the universe.

    It has been developed specifically for emerging courses in astrobiology, though it can also be used for introductory astronomy.

      In the constellation of Eridanus, there lurks a cosmic mystery: It’s as if something has taken a huge bite out of the universe. But what is the culprit? The hole in the universe is just one of many puzzles keeping cosmologists busy. Supermassive black holes, bubbles of nothingness gobbling up space, monster universes swallowing others—these and many other bizarre ideas are being pursued by scientists. Due to breathtaking progress in astronomy, the history of our universe is now better understood than the history of our own planet. But these advances have uncovered some startling riddles. In this electrifying new book, renowned cosmologist and author Paul Davies lucidly explains what we know about the cosmos and its enigmas, exploring the tantalizing—and sometimes terrifying—possibilities that lie before us. As Davies guides us through the audacious research offering mind-bending solutions to these and other mysteries, he leads us up to the greatest outstanding conundrum of all: Why does the universe even exist in the first place? And how did a system of mindless, purposeless particles manage to bring forth conscious, thinking beings? Filled with wit and wonder, What’s Eating the Universe? is a dazzling tour of cosmic questions, sure to entertain, enchant, and inspire us all.
