Book Description
In April 2010, fifty years to the month after the first experiment in the Search for Extraterrestrial Intelligence (SETI), scholars from a range of disciplines—including astronomy, mathematics, anthropology, history, and cognitive science—gathered at NASA's biennial Astrobiology Science Conference (AbSciCon) for a series of sessions on the search for intelligent life. This book highlights the most recent developments in SETI discussed at that conference, emphasizing the ways that SETI has grown since its inception. The volume covers three broad themes: First, leading researchers examine the latest developments in observational SETI programs, as well as innovative proposals for new search strategies and novel approaches to signal processing. Second, both proponents and opponents of "Active SETI" debate whether humankind should be transmitting intentional signals to other possible civilizations, rather than only listening. Third, constructive proposals for interstellar messages are juxtaposed with critiques that ask whether any meaningful exchange is possible with an independently evolved civilization, given the constraints of contact at interstellar distances, where a round-trip exchange could take centuries or millennia. As we reflect on a half-century of SETI research, we are reminded of the expansion of search programs made possible by technological and conceptual advances. In this spirit of ongoing exploration, the contributors to this book advocate a diverse range of approaches to make SETI increasingly more powerful and effective, as we embark on the next half-century of searching for intelligence beyond Earth.

Book Description
Mathematics is as much a part of our humanity as music and art. And it is our mathematics that might be understandable, even familiar, to a distant race and might provide the basis for mutual communication. This book discusses, in a conversational way, the role of mathematics in the search for extraterrestrial intelligence. The author explores the science behind that search, its history, and the many questions associated with it, including those regarding the nature of language and the philosophical/psychological motivation behind this search.

Book Description
This book is a collection of essays written by the very scientists and engineers who have led, and continue to lead, the scientific quest known as SETI, the search for extraterrestrial intelligence. Divided into three parts, the first section, ‘The Spirit of SETI Past’, written by the surviving pioneers of this then emerging discipline, reviews the major projects undertaken during the first 50 years of SETI science and the results of that research. In the second section, ‘The Spirit of SETI Present’, the present-day science and technology is discussed in detail, providing the technical background to contemporary SETI instruments, experiments, and analytical techniques, including the processing of the received signals to extract potential alien communications. In the third and final section, ‘The Spirit of SETI Future’, the book looks ahead to the possible directions that SETI will take in the next 50 years, addressing such important topics as interstellar message construction, the risks and assumptions of interstellar communications, when we might make contact, what aliens might look like and what is likely to happen in the aftermath of such a contact.

Book Description
If you are interested in how researchers plan to search the heavens for signs of intelligent life, you should have this book. SETI 2020 is a new, and remarkably comprehensive study of how scientists busy with the Search for Extraterrestrial Intelligence (SETI) should direct their efforts between now and the year 2020. Distilling the work of dozens of top SETI experts, astronomers, and technology mavens, this book gives an overview of the problem of finding evidence for extraterrestrial technologies, and how to best address it. New radio telescopes consisting of large arrays of relatively small antennas are proposed and detailed. So are new types of antennas that can survey the entire sky at once. Of particular interest is the extensive treatment of optical SETI -- the search for signals beamed our way using high-powered, pulsed lasers or their equivalent. A book that's interesting for both the layman and the technically sophisticated, SETI 2020 is the definitive publication in this fascinating field.

Book Description
"A cogent, engaging history of humanity's most ambitious quest--seeking outward for other minds."--David Brin, author of Existence "A fascinating perspective on humankind's obsession for knowing if there is anyone else out there."--Gerrit L. Verschuur, author of The Invisible Universe: The Story of Radio Astronomy "Squeri has written what will likely be the definitive history of the early days of SETI that includes profiles of some of its leading characters."--Ben Zuckerman, coeditor of Extraterrestrials: Where Are They? "An insightful history that explores the scientific foundations of the modern-day search for our place in the cosmos. Waiting for Contact delivers unparalleled access to the inner history of SETI and invites us to ride along on the journey to answer one of science's ultimate questions: Are we alone?"--Douglas Vakoch, president, METI International "Waiting for Contact is a balanced account, telling the tale of the search for extraterrestrial intelligence without the overpromise usually trumpeted by enthusiastic proponents and the hyperventilation so commonly added by UFO enthusiasts. If you are simply interested in the history, unvarnished by an agenda, you'll enjoy this book."--Don Lincoln, author of Alien Universe: Extraterrestrial Life in Our Minds and in the Cosmos Imagine a network of extraterrestrials in radio contact with each other across the universe, superior beings who hail from advanced civilizations quadrillions of miles away, just waiting for Earth to tune in. Some people believe it’s only a matter of time before we discover the right "station." Waiting for Contact tells the story of the Search for Extraterrestrial Intelligence (SETI) movement, which emerged in 1959 as astronomers began using radio telescopes to listen for messages from space. New technological developments turned what once was speculation into science. Boosted by support from Frank Drake, Philip Morrison, Carl Sagan, and the genre of science fiction, the SETI movement gained followers and continues to capture imaginations today. In this one-of-a-kind history, Lawrence Squeri looks at the people, reasons, goals, and mindsets behind SETI. He shows how it started as an expression of the times, a way out of Cold War angst with hope for a better world. SETI's early advocates thought that with guidance from technically and ethically advanced outsiders, humanity might learn how to avoid horrors like nuclear annihilation and societal collapse from overpopulation. Some hoped that good news from outer space might reveal a cure for cancer or even the secret of immortality. Squeri also describes the challenges SETI has faced over the years: the struggle to be taken seriously by the scientific community and by NASA, competition for access to radio telescopes, perpetual lack of funding, and opposition from influential politicians. He covers the rise and fall of Soviet SETI and the few rare meetings between Soviet and American astronomers. Despite many setbacks, the movement pressed forward with the aid of private donations and developed outreach programs. Volunteers can now help search for new civilizations on their personal computers by joining the SETI@Home project. Today, SETI researchers continue to see themselves as explorers. They often identify with Columbus, and just as Columbus never realized the full implications of his discovery, we cannot predict what will happen if contact is made. This book points out that if, against all expectations, the embattled SETI movement finally succeeds, the long-awaited first signal picked up by its radio antennas will usher the greatest shift in human history. A new adventure will begin. Lawrence Squeri is professor emeritus of history at East Stroudsburg University.

Book Description
This book introduces the Statistical Drake Equation where, from a simple product of seven positive numbers, the Drake Equation is turned into the product of seven positive random variables. The mathematical consequences of this transformation are demonstrated and it is proven that the new random variable N for the number of communicating civilizations in the Galaxy must follow the lognormal probability distribution when the number of factors in the Drake equation is allowed to increase at will. Mathematical SETI also studies the proposed FOCAL (Fast Outgoing Cyclopean Astronomical Lens) space mission to the nearest Sun Focal Sphere at 550 AU and describes its consequences for future interstellar precursor missions and truly interstellar missions. In addition the author shows how SETI signal processing may be dramatically improved by use of the Karhunen-Loève Transform (KLT) rather than Fast Fourier Transform (FFT). Finally, he describes the efforts made to persuade the United Nations to make the central part of the Moon Far Side a UN-protected zone, in order to preserve the unique radio-noise-free environment for future scientific use.

Book Description
Titan is practically a planet in its own right, with a diameter similar to that of Mercury, methane rainstorms, organic soot and ethane seas. All of the most detailed knowledge on the moon's geology, volcanology, meteorology, marine sciences and chemistry are gathered together here to paint a factually accurate hypothetical future of early human colonization on this strange world. The views from Titan’s Mayda Outpost are spectacular, but all is not well at the moon's remote science base. On the shore of a methane sea beneath glowering skies, atmospherics researcher Abigail Marco finds herself in the middle of murder, piracy and colleagues who seem to be seeing sea monsters and dead people from the past. On the Shores of Titan’s Farthest Sea provides thrills, excitement and mystery – couched in the latest science – on one of the Solar System’s most bizarre worlds, Saturn’s huge moon Titan. "This riveting story, set against a plausibly well integrated interplanetary space, carries us along with its bright and interesting characters. We feel absolutely transported to a hauntingly beautiful and alien Titan through Carroll's masterful weaving of art and science." – Jani Radebaugh, Professor of Planetary Sciences, Titan dune expert, BYU "It's a fun read! Really makes Titan come alive, literally..." – Astrophysicist and author Ralph Lorenz "Michael Carroll's new novel "On the Shores of Titan's Farthest Sea" (Springer) is a gripping, good-vs-evil tale that sparkles with imagination. It's set on the shores of Kraken Mare, the vast methane sea found high in the northern latitudes of Saturn's moon, Titan, in a future when humanity has spread throughout the solar system. The villains are wicked, the heroes are scientists (Thanks, Mike!), the story is convincing, the dialogue snappy, and the scenery is right out of our catalog of findings on this cold, hazy and alien world. If you fancy skipping forward 250 years and checking out how humankind might be navigating the very geography and landforms we have uncovered in our years touring Saturn, this book is for you!" --Carolyn Porco, leader of the Cassini Imaging Science team and the Director of the Cassini Imaging Central Laboratory for Operations (CICLOPS) at the Space Science Institute in Boulder, Colorado
