The Quest To Discover Life Beyond Earth. "The 'dreams' that I write of are not the usual ones, the images that come up in our minds involuntarily during certain stages of sleep, but rather the hopes and expectations that we have lavished upon other worlds around us."-from the Preface. The surprisingly long history of debate over extraterrestrial life is full of marvelous visions of what life "out there" might be like, as well as remarkable stories of alleged sightings and heated disputes about the probability that life might actually have arisen more than once. In Planetary Dreams, acclaimed author Robert Shapiro explores this rich history of dreams and debates in search of the best current answers to the most elusive and compelling of all questions: Are we alone? In his pursuit, he presents three contrasting views regarding how life might have started: through Divine Creation, by a highly unlikely stroke of luck, or by the inevitable process of a natural law that he terms the Life Principle. We are treated to a lively fictional dinner debate among the leading proponents of these schools of thought-with the last named group arguing that life has almost surely formed in many places throughout the universe, and the others that life may well be entirely unique to our own blue planet. To set the stage for a deep exploration of the question, the author then leads us on a fantastic journey through the museum of the cosmos, an imagined building that holds models of the universe at different degrees of magnification. We then journey deep into inner space to view the astonishingly intricate life of a single cell, and learn why the origin of such a complex object from simple chemical mixtures poses one of the most profound enigmas known to science. Writing in a wonderfully entertaining style, Shapiro then reviews the competing theories about the start of life on Earth, and suggests the debate may best be settled by finding signs of life on the other worlds of our solar system. He takes us on a guided tour of the most likely sites, from the underground hot springs of Mars to the ice-covered oceans of Jupiter's airless moons. Along the way, he shares a wealth of fascinating stories about the ways in which our views of the heavens have changed, from the theories of ancient philosphers, who argued that the Moon was inhabited, to the current Origins and Astrobiology initiatives of NASA. He describes the probes that will be sent out in the near future in pursuit of the first compelling physical evidence of life beyond Earth, and concludes with a radical suggestion about how this quest might be supported through the next millennium. As we launch into an exciting new era of space exploration, Planetary Dreams offers a thoughtful and entertaining exploration of both the history of our hopes and expectations and a vision of a possible future in which the discovery of life elsewhere will provide a new view of our place in the universe.

Scotty is a lonely, scared Earth boy who goes to the faraway planet of Kestrellia for the summer to live with his dad. He meets an alien boy named Aldy, and the two become fast friends. Aldy has a secret. As the son of the king, when he turns ten, he has to go on a quest for a beautiful blue jewel, the Blue Kyrolite, high up in the cold mountains of Kestrellia to prove he is worthy to become the next king. Aldy asks Scotty to go with him on his quest for the jewel, which they soon find out is more difficult than expected. Along the way, Scotty learns how to deal with his fears while the boys realize that they are not really supposed to be looking for a beautiful jewel after all...but what is it they are supposed to find?

Ever since the serendipitous discovery of planet Uranus in 1871, astronomers have been hunting for new worlds in the outer regions of our solar system. This exciting and ongoing quest culminated recently in the discovery of hundreds of ice dwarfs in the Kuiper belt, robbed Pluto from its ‘planet’ status, and led to a better understanding of the origin of the solar system. This timely book reads like a scientific ‘who done it’, going from the heights of discovery to the depths of disappointment in the hunt for ‘Planet X’. Based on many personal interviews with astronomers, the well-known science writer Govert Schilling introduces the heroes in the race to be the first in finding another world, bigger than Pluto.
As long as the human species has existed, men and women have had to contend with the unpredictable forces of nature. Geographer Barry A. Vann brings a unique perspective to this age-old struggle in this illuminating overview of human population shifts and their precarious relationship with climate change and geography. Vann takes us on a journey along the migration routes of the earliest modern humans and tells why our ancestors chose to settle down in places that can be best described as natural utopias. In the religiously oriented worldview of ancient peoples, such places took on a sacred aura of divine favor. Similarly, destructive events such as volcanic eruptions and earthquakes were interpreted as expressions of divine wrath. Vann shows how the ancient texts of the Bible and the Qur’an offer glimpses of past climates that were distinctly different from the climate of our time. He also discusses the rise of technology as a means of controlling the threatening features of the natural world. Though technology has enabled humanity to cope with hostile climates, it has also created a false sense of security. Vann notes that population clusters are increasing in dangerous areas and that no technology can protect vulnerable groups from major-category hurricanes, tornadoes, or earthquakes. Finally, he considers our current anxieties regarding global warming, pointing out that this focus has obscured a good deal of historical and geological evidence for a return of another ice age. The Forces of Nature offers a challenging perspective on the precarious balance between fragile human communities and their often-threatening environments.

Classical Feedback Control with Nonlinear Multi-Loop Systems by Boris J. Lurie,Paul Enright Pdf
Classical Feedback Control with Nonlinear Multi-Loop Systems describes the design of high-performance feedback control systems, emphasizing the frequency-domain approach widely used in practical engineering. It presents design methods for high-order nonlinear single- and multi-loop controllers with efficient analog and digital implementations. Bode integrals are employed to estimate the available system performance and to determine the ideal frequency responses that maximize the disturbance rejection and feedback bandwidth. Nonlinear dynamic compensators provide global stability and improve transient responses. This book serves as a unique text for an advanced course in control system engineering, and as a valuable reference for practicing engineers competing in today’s industrial environment.
