Book Description
In Manifold: Time, space explorer Reid Malenfant journeyed to the edge of time. Now, in this second installment to the Manifold series we find him embarking on a grand tour of the universe, while the fate of earth itself appears threatened by the two-pronged menace of an emerging alien presence and out-of-control environmental degradation.Following Malenfant's journey of millions of light years, we find him once more faced with a choice both impossible and necessary -- a choice that will push him beyond terror, beyond sanity, beyond humanity itself.

Book Description
This book presents an overview of the outcomes resulting from applying the dynamical systems approach to space mission design, a topic referred to as "Space Manifold Dynamics" (SMD). It is a natural follow-on to the international workshop "Novel Spaceways for Scientific and Exploration Missions," which was held in October 2007 at the Telespazio Fucino Space Centre (Italy) under the auspices of the Space OPS Academy. The benefits and drawbacks of using the Lagrangian points and the associated trajectories for present and future space missions are discussed. The related methods and algorithms are also described in detail. Each topic is presented in articles that were written as far as possible to be self consistent; the use of introductory sections and of extended explanations is included in order to address the different communities potentially interested in SMD: space science, the aerospace industry, manned and unmanned exploration, celestial mechanics, and flight dynamics.

Book Description
In mathematical physics, Minkowski space or Minkowski spacetime is a combination of Euclidean space and time into a four-dimensional manifold where the spacetime interval between any two events is independent of the inertial frame of reference in which they are recorded. Although initially developed by mathematician Hermann Minkowski for Maxwell's equations of electromagnetism, the mathematical structure of Minkowski spacetime was shown to be an immediate consequence of the postulates of special relativity. Minkowski space is closely associated with Einstein's theory of special relativity, and is the most common mathematical structure on which special relativity is formulated. While the individual components in Euclidean space and time will often differ due to length contraction and time dilation, in Minkowski spacetime, all frames of reference will agree on the total distance in spacetime between events. Because it treats time differently than the three spatial dimensions, Minkowski space differs from four-dimensional Euclidean space. In Euclidean space, the isometry group (the maps preserving the regular inner product) is the Euclidean group. The analogous isometry group for Minkowski space, preserving intervals of spacetime equipped with the associated non-positive definite bilinear form (here called the Minkowski inner product, ) is the Poincare group. The Minkowski inner product is defined as to yield the spacetime interval between two events when given their coordinate difference vector as argument."

Book Description
Hoping to make the text more accessible to readers not schooled in the probabalistic tradition, Stroock (affiliation unspecified) emphasizes the geometric over the stochastic analysis of differential manifolds. Chapters deconstruct Brownian paths, diffusions in Euclidean space, intrinsic and extrinsic Riemannian geometry, Bocher's identity, and the bundle of orthonormal frames. The volume humbly concludes with an "admission of defeat" in regard to recovering the Li-Yau basic differential inequality. Annotation copyrighted by Book News, Inc., Portland, OR.

Book Description
Manifolds, the higher-dimensional analogs of smooth curves and surfaces, are fundamental objects in modern mathematics. Combining aspects of algebra, topology, and analysis, manifolds have also been applied to classical mechanics, general relativity, and quantum field theory. In this streamlined introduction to the subject, the theory of manifolds is presented with the aim of helping the reader achieve a rapid mastery of the essential topics. By the end of the book the reader should be able to compute, at least for simple spaces, one of the most basic topological invariants of a manifold, its de Rham cohomology. Along the way, the reader acquires the knowledge and skills necessary for further study of geometry and topology. The requisite point-set topology is included in an appendix of twenty pages; other appendices review facts from real analysis and linear algebra. Hints and solutions are provided to many of the exercises and problems. This work may be used as the text for a one-semester graduate or advanced undergraduate course, as well as by students engaged in self-study. Requiring only minimal undergraduate prerequisites, 'Introduction to Manifolds' is also an excellent foundation for Springer's GTM 82, 'Differential Forms in Algebraic Topology'.

Book Description
The power that analysis, topology and algebra bring to geometry has revolutionised the way geometers and physicists look at conceptual problems. Some of the key ingredients in this interplay are sheaves, cohomology, Lie groups, connections and differential operators. In Global Calculus, the appropriate formalism for these topics is laid out with numerous examples and applications by one of the experts in differential and algebraic geometry. Ramanan has chosen an uncommon but natural path through the subject. In this almost completely self-contained account, these topics are developed from scratch. The basics of Fourier transforms, Sobolev theory and interior regularity are proved at the same time as symbol calculus, culminating in beautiful results in global analysis, real and complex. Many new perspectives on traditional and modern questions of differential analysis and geometry are the hallmarks of the book. The book is suitable for a first year graduate course on Global Analysis.

Book Description
A hard-SF cli-fi saga set against the background of the birth of the solar system. Filled to the brim with big ideas and breathtaking worldbuilding In the year 2570, a sleeper will wake . . . In the mid-21st century, the Kernel, a strange object on a five-hundred-year-orbit, is detected coming from high above the plane of the solar system. Could it be an alien artefact? In the middle of climate-change crises, there is no mood for space-exploration stunts - but Reid Malenfant, elderly, once a shuttle pilot and frustrated would-be asteroid miner, decides to go take a look anyway. Nothing more is heard of him. But his ex-wife, Emma Stoney, sets up a trust fund to search for him the next time the Kernel returns . . . By 2570 Earth is transformed. A mere billion people are supported by advanced technology on a world that is almost indistinguishable from the natural, with recovered forests, oceans, ice caps. It is not an age for expansion; there are only small science bases beyond the Earth. But this is a world you would want to live in: a Star Trek without the stars. After 500 years the Kernel returns, and a descendant of Stoney, who Malenfant will call Emma II, mounts a mission to see what became of Malenfant. She finds him still alive, cryo-preserved . . . His culture-shock encounter with a conservative future is entertaining . . . But the Kernel itself turns out to be attached to a kind of wormhole, through which Malenfant and Emma II, exploring further, plummet back in time, across five billion years . . . Readers are blown away by World Engines: Destroyer: 'The book quickly becomes epic in a massive, yet thoroughly believable way, precisely because the story is grounded in all of these well-realised characters' Goodreads reviewer, ⭐ ⭐ ⭐ ⭐ ⭐ 'It is a really good Cli-Fi but not only ecological . . . It touches on very many different topics that are very much in our future' Goodreads reviewer, ⭐ ⭐ ⭐ ⭐ ⭐ 'It's a great sci-fi novel, well written and gripping. I loved the amazing world building, the fleshed out cast of characters and the plot' Goodreads reviewer, ⭐ ⭐ ⭐ ⭐ ⭐ 'This is a complex book with a lot going on . . . Suffice to say this was a fantastic read with a great story, good characters & a world that I would very much like to come back to' Goodreads reviewer, ⭐ ⭐ ⭐ ⭐ ⭐ 'The large scale is always where Baxter is so exciting and passionate and it pays off in spades in the final act. Worth your time to read and enjoy' Goodreads reviewer, ⭐ ⭐ ⭐ ⭐ ⭐ 'If you love your science fiction hard, look no further than Stephen Baxter to find your fix. He was literally a rocket scientist. His work is always grounded in science' Goodreads reviewer, ⭐ ⭐ ⭐ ⭐ ⭐

Book Description
New York City is home to some of the most recognizable places in the world. As familiar as the sight of New Year’s Eve in Times Square or a protest in front of City Hall may be to us, do we understand who controls what happens there? Kristine Miller delves into six of New York’s most important public spaces to trace how design influences their complicated lives. Miller chronicles controversies in the histories of New York locations including Times Square, Trump Tower, the IBM Atrium, and Sony Plaza. The story of each location reveals that public space is not a concrete or fixed reality, but rather a constantly changing situation open to the forces of law, corporations, bureaucracy, and government. The qualities of public spaces we consider essential, including accessibility, public ownership, and ties to democratic life, are, at best, temporary conditions and often completely absent. Design is, in Miller’s view, complicit in regulation of public spaces in New York City to exclude undesirables, restrict activities, and privilege commercial interests, and in this work she shows how design can reactivate public space and public life. Kristine F. Miller is associate professor of landscape architecture at the University of Minnesota.
