Science, Seti, and Mathematics
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.

Reinventing SETI
For millennia, humanity has looked up at the sprawling tapestry of stars and wondered what lay beyond. With time, we learned that each star is not a pinprick point in a domed sky, but a massive plasma sphere so far away that the distance becomes incomprehensible to the human mind, measured in light years of millions and billions. This distance invokes crucial questions. Do we share the universe with other intelligent lifeforms? If so, how do we approach the Search for Extraterrestrial Intelligence (SETI)? Lastly, do we need to examine our assumptions about extraterrestrial intelligence?Reinventing SETI clears out the cobwebs of outdated or wrongheaded SETI paradigms such as Fermi's Paradox, the Drake Equation, and METI (i.e., proactively sending signals from Earth to putative aliens). It argues that scientists should approach the pursuit of extraterrestrials (ETs) in a more effective manner. Author John Gertz states that ETs, as biological lifeforms themselves, cannot accomplish interstellar travel, but have instead placed robotic probes throughout the universe, perhaps even in our own Solar System. Gertz also warns that humankind is woefully unprepared for the day of First Contact with an alien probe right here in our own backyard. He suggests contingency planning, involving international cooperation as well as broad cross-disciplinary expertise. Humorous and deeply informative, this book takes the reader through the universe, conventional SETI methods, ideas on future ET exploration, and a discussion on who else shares this space.

Mathematical SETI
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.

Search for ExtraTerrestrial Intelligence
This book presents the latest knowledge of the newly discovered Earth-like exoplanets and reviews improvements in both radio and optical SETI. A key aim is to stimulate fresh discussion on algorithms that will be of high value in this extremely complicated search. Exoplanets resembling Earth could well be able to sustain life and support the evolution of technological civilizations, but to date, all searches for such life forms have proved fruitless. The failings of SETI observations are well recognized, and a new search approach is necessary. In this book, different detection algorithms that exploit state-of-the-art, low-cost, and extremely fast multiprocessors are examined and compared. Novel methods such as the agnostic entropy and high-sensitivity blind signal extraction algorithms should represent a quantum leap forward in SETI. The book is of interest to all researchers in the field and hopefully stimulates significant progress in the search for extraterrestrial intelligence.

Evo-SETI
This book offers a vision of how evolutionary life processes can be modelled. It presents a mathematical description that can be used not only for the full evolution of life on Earth from RNA to modern human societies, but also the possible evolution of life on exoplanets, thus leading to SETI, the current Search for ExtraTerrestrial Intelligence. The main premise underlying this mathematical theory is that the Geometric Brownian Motion (GBM) can be applied as a key stochastic process to model the evolution of life. In the resulting Evo-SETI Theory, the life of any living thing (a cell, an animal, a human, a civilization of humans, or even an ET civilization) is represented by a b-lognormal, i.e., a lognormal probability density function starting at a precise instant (b, birth) then increasing up to a peak time, then decreasing to senility time and then continuing as a straight line down to the time of death.Using this theory, Claudio Maccone arrives at remarkable hypotheses on the development of life and civilizations, the possibility of extraterrestrial life, and when computers will take over the reins from us humans (Singularity). The book develops the mathematical Evo-SETI Theory by integrating a set of articles that the author has published in various journals on Astrobiology and Astronautical Research.

Project Haystack
Through hands-on activities, middle school students learn about the scale and structure of the Milky Way galaxy -- a cosmic haystack. They study SETI science by using simple astronomical tools to solve some of the problems of sending and receiving messages beyond our solar system.

Rise of Intelligence and Culture
Students examine the concepts of intelligence, culture, technology and communication in this study. Using the information, they can form a culture for an intelligent organism that could exist on an unknown planet. A set of colour transparencies are also available (ISBN 1-56308-414-7).

Omm Sety's Egypt
Revelations in Egyptology, based on the diaries of Dorothy Eady, better known as Omm Sety.Omm Sety, a brilliant, adventuring Englishwoman, worked under some of the greatest Egyptologists of the 20th century and "saw" into the past. Hers is a story of ancient love – of gods, pyramids, pharaohs and queens, and treasures that wait beneath the sand.In Omm Sety's Egypt, the authors present never-before-seen episodes from her truly incredible life, including important revelations about Egypt's lost history. Hanny el Zeini was her close friend during the many years she lived in the ancient holy city of Abydos. It was a friendship filled with star-lit evenings among the ruins of ancient temples, speaking of the mysteries of this land they both loved. Dr. el Zeini was her trusted confidant to whom she revealed her secret other life in 19th Dynasty Egypt. Shortly before her death in 1981, she gave him her diaries, which chronicled her life in two worlds. Drawing on Omm Sety's diaries and on hundreds of hours of recorded conversations and Dr. el Zeini's own writings, co-author Catherine Dees brings this extraordinary material together into a story that asks the reader to suspend disbelief and enter into the mystery that was Omm Sety.

How Might Life Evolve on Other Worlds?
Through a variety of science activities, this work helps students explore the evolution of life on Earth and search for clues to the possible evolution of life on an unknown planet beyond our solar system. Students can then create life forms that could exist on that planet.
