It has been 15 years since the events of Einstein’s Bridge. George and Alice Griffin and Roger Coulton have established the Iris Foundation, a powerful island-isolated research organization tasked with exploiting the technologies learned from the Makers, re-learning Maker techniques for creating wormholes, reestablishing contact with the Makers, and protecting Earth from Hive invasions. Sparked by a new idea from Roger, Iris researchers finally master wormhole technology and use accelerated wormholes to create Fermi Station in the Oort Cloud. Contact is established with the Makers and the Centaurs, a justice-seeking robotic civilization in our galaxy. The triple alliance mounts a three-pronged attack on the Hive world, destroying the Hive and one of its colonies. A second Hive colony cannot be located and could pose a future problem. Iris launches an armada of accelerated wormholes to probe nearby star systems and establishes a colonization base on Orca, an Earth-like moon of Bowhead, a giant planet in the Tau Ceti system. Mankind has reached the stars. At the publisher's request, this title is sold without DRM (Digital Rights Management).

In a 1950 conversation at Los Alamos, four world-class scientists generally agreed, given the size of the Universe, that advanced extraterrestrial civilizations must be present. But one of the four, Enrico Fermi, asked, "If these civilizations do exist, where is everybody?" Given the fact that there are perhaps 400 million stars in our Galaxy alone, and perhaps 400 million galaxies in the Universe, it stands to reason that somewhere out there, in the 14 billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. Webb discusses in detail the 50 most cogent and intriguing solutions to Fermi's famous paradox.

Guesstimation is a book that unlocks the power of approximation--it's popular mathematics rounded to the nearest power of ten! The ability to estimate is an important skill in daily life. More and more leading businesses today use estimation questions in interviews to test applicants' abilities to think on their feet. Guesstimation enables anyone with basic math and science skills to estimate virtually anything--quickly--using plausible assumptions and elementary arithmetic. Lawrence Weinstein and John Adam present an eclectic array of estimation problems that range from devilishly simple to quite sophisticated and from serious real-world concerns to downright silly ones. How long would it take a running faucet to fill the inverted dome of the Capitol? What is the total length of all the pickles consumed in the US in one year? What are the relative merits of internal-combustion and electric cars, of coal and nuclear energy? The problems are marvelously diverse, yet the skills to solve them are the same. The authors show how easy it is to derive useful ballpark estimates by breaking complex problems into simpler, more manageable ones--and how there can be many paths to the right answer. The book is written in a question-and-answer format with lots of hints along the way. It includes a handy appendix summarizing the few formulas and basic science concepts needed, and its small size and French-fold design make it conveniently portable. Illustrated with humorous pen-and-ink sketches, Guesstimation will delight popular-math enthusiasts and is ideal for the classroom.

This volume reviews the current understanding of the Fermi-Pasta-Ulam (FPU) Problem without trying to force coherence on differing perspectives on the same problem by various groups or approaches. The contributions lead the interested but inexperienced reader through gradual understanding, starting from general analysis and proceeding towards more specialized topics. The volume also includes a reprint of the original Fermi-Pasta-Ulam paper.

The Great Silence explores the multifaceted problem named after the great Italian physicist Enrico Fermi and his legendary 1950 lunchtime question "Where is everybody?" In many respects, Fermi's paradox is the richest and the most challenging problem for the entire field of astrobiology and the Search for ExtraTerrestrial Intelligence (SETI) studies. This book shows how Fermi's paradox is intricately connected with many fields of learning, technology, arts, and even everyday life. It aims to establish the strongest possible version of the problem, to dispel many related confusions, obfuscations, and prejudices, as well as to offer a novel point of entry to the many solutions proposed in existing literature. Ćirković argues that any evolutionary worldview cannot avoid resolving the Great Silence problem in one guise or another.

Follow Nobel laureate and legendary teacher Enrico Fermi’s lost course on geophysics. Nobel Prize–winning physicist Enrico Fermi (1901–54) is known for his work on experimental particle and nuclear physics, quantum theory, and statistical mechanics, and for his particular ability to condense complicated problems into approximations for understanding and testing theory in a variety of scientific disciplines. Six of his graduate students went on to win their own Nobel Prizes. Unearthing Fermi’s Geophysics opens a window onto two underrepresented facets of this extraordinary thinker: Fermi’s teaching and his contribution to the field of geophysics. Drawing on Fermi’s handwritten calculations and notes, many of which are reproduced here in photographic facsimile, physicists Gino Segrè and John Stack have reconstructed a coursebook of Fermi’s insights into the physics of a range of geological and atmospheric phenomena. From gravity on Earth to thermodynamics in the atmosphere, the physics of raindrops, the Coriolis effect in hurricanes, tidal physics, earthquakes and seismic waves, Earth’s magnetism, atmospheric electricity, and much more, Unearthing Fermi’s Geophysics reveals the hidden workings of the world above, around, and below us—and of the mind of a great scientist who was able to bring those physical workings to light.

Robert Powell, a founding Board member of the Scientific Coalition for UAP Studies, has studied the UFO subject for 17 years. His work is encapsulated in UFOs: A Scientist Explains What We Know (And Don’t Know) which provides a scientific rationale for the reality of non-terrestrial craft that are intelligently controlled. Powell begins his book by familiarizing the reader with the history of UFOs and he identifies the more enigmatic and interesting UFO sightings. He examines the characteristics of these sightings that argue against a prosaic explanation: extreme acceleration, electromagnetic interference, bending light, no obvious propulsion mechanisms, and a lack of interaction with the atmosphere. Powell discusses the recent events that have caused our government to change the term from UFO to UAP. Included is information never before released indicating the government possesses not just two videos but five videos from 2015 of UFOs operating in the vicinity of the USS Roosevelt nuclear aircraft carrier. Powell’s later chapters in the book discuss the extraterrestrial hypothesis considering the thousands of exoplanets that have been discovered in the last twenty years. Powell challenges the reader to consider all the implications that must be considered if intelligent life discovers us first. He looks at how we as individuals and as a society react to UFOs. He documents actions taken by our military that include instances when we have fired on UFOs. Powell argues that it is time for a change in the study of UFOs. The phenomenon has been with us for 75 years and we have learned very little as the decades have passed. The author makes the case for what needs to be done going forward. The solution he proposes will require a paradigm shift in our thinking and his book provides the information needed to understand that paradigm shift.
