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.
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.
This one-semester overview will be enjoyed by undergraduate students with an interest in the physical sciences, such as astronomy, chemistry, engineering or physics, as well as by any curious student interested in learning about our celestial science. The mathematics required for understanding the text is on the level of simple algebra, for that is all that is needed to describe the fundamental principles.
The text is of sufficient breadth and depth to prepare the interested student for more advanced specialised courses in the future. Astronomical examples are provided throughout the text, to reinforce the basic concepts and physics, and to demonstrate the use of the relevant formulae. In this way, the student learns to apply the fundamental equations and principles to cosmic objects and situations. Astronomical and physical constants and units as well as the most fundamental equations can be found in the appendix. Essential Astrophysics goes beyond the typical textbook by including references to the seminal papers in the field, with further reference to recent applications, results, or specialised literature.
"Bulging with concise explanations and 142 clarifying diagrams and photos, the book probably represents some of the best pedagogy in the solar system on these topics. ... just the right level for most undergraduates. ... Open-minded scientists looking for an authoritative tour of astrobiology will enjoy the book ... . The author’s summary of exoplanet detection techniques is excellent ... . Jones keeps us interested with simple explanations ... . His approach is quite an achievement ... . " (Charley Lineweaver, Physics Today, February, 2005).
"This is a textbook suitable for university use. ... this is one of the best. ... includes excellent recent images of Mars, Europa and elsewhere, and is richly illustrated with explanatory diagrams. ... There is a useful index, a glossary and a list of ‘resources’ (websites and books)." (Malcolm Walter, Australian Physics, Vol. 42 (3) July/August 2005)
"What is required for life, and where might it have evolved? ... These are the questions that are addressed in this wide ranging, well written and thought provoking book. ... But for anyone wishing to follow ... Jones’ book is an excellent start." (Dr. C.M.Linton, Contemporary Physics, Vol. 46 (3), 2005)
"This book centres on the search for life in the Solar System and beyond. It includes an overview of many of the disciplines involved in this field of research, which include astronomy, biology and geology. ... It was good to see that the astronomy has been kept fairly descriptive and not too mathematical. This keeps the flow of the book. ... As an overview of the key subjects involved in astrobiology for a university course, I think this book is successful." (James Silvester, Astronomy Now, March, 2005)
Although, at present there is no firm evidence for extraterrestrial life, enormous progress has been made in recent years, both in our understanding of life on Earth and of the potential for life existing elsewhere in the universe. Life in the Solar System and Beyond embaces aspects form all the osre related fields (astronomy, planetary science, chemistry, biology, and Physics). This excellent and thought-provoking introduction:Addresses the important question of what is life, and discusses the origins and evolution of life on Earth, as well as its probable fate Looks at places within our Solar System, beyond Earth, especially where life might exist, such as Mars and Europa Includes the very latest data on searches for planets around other stars, the results of these searches, and discusses what conditions might be like Speculates on possible life elsewhere in the Universe beyond our Solar system, and assesses our chances of making contact, if there is intelligent life out there Includes end of chapter summaries to help the reader grasp the main concepts to carry forward Provides a list of resources, including useful websites at the end of the book which will enable the reader to keep up to date in this rapidly moving field
