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).

Gripping novel of hard science fiction by physicist author recounts discovery of the Twistor Effect, which opens doors into countless alternate universes and draws dangerous attention from industrial spies and corporate killers.

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 collection is devoted to problems of operator theory with a random potential and a number of problems of statistical physics. For the Schrodinger operator with a potential randomly depending on time, mean wave operators, and the mean scattering operator are computed, and it is shown that the averaged dynamics behaves like free dynamics in the limit of infinite time. Results of applying the method of functional integration to some problems of statistical physics are presented: the theory of systems with model Hamiltonians and their dynamics, ferromagnetic systems of spin 1/2, Coulomb and quantum crystals. This collection is intended for specialists in spectral theory and statistical physics.

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.
