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 UnitedNations 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.

Most books on interstellar flight focus on propulsion systems, but this work addresses two equally crucial aspects of such missions. The first part explores the Sun's gravitational lensing effect for scientific missions extending to 550 AU and beyond. The author details how the Sun acts as a gravitational lens, the scientific investigations possible along the journey and at the 550 AU boundary, the requirements for exiting the Solar System at high speeds, and various project ideas for interstellar exploration. The second part tackles the challenges of communication between an interstellar spacecraft and Earth, particularly at high velocities. It evaluates mathematical tools related to the Karhunen-Loève Transform (KLT) for optimal telecommunications, which may one day facilitate communication for humans traveling through the Galaxy. This section begins with a summary of the author’s 2003 Pešek Lecture at the IAC in Bremen, introducing KLT to engineers and newcomers. A DVD is planned to accompany the book, containing full mathematical derivations of KLT for those interested, while the text will present results without extensive mathematical proofs. This approach allows astronautical engineers to understand practical applications without getting overwhelmed by complex mathematics.

The book provides a mathematical framework for modeling evolutionary processes, spanning from the origins of life on Earth to the development of modern human societies. It also explores the potential evolution of life on exoplanets, contributing to the Search for ExtraTerrestrial Intelligence (SETI). This comprehensive approach combines theoretical insights with practical applications in understanding life's evolution across different environments.
