“Faithfully emulates van Vogt’s labyrinthine plot twists and energetic prose while answering questions. . . . that have burned in fans’ minds for decades.” —Booklist In this heart-stopping sequel to A.E. van Vogt’s World of Null-A, Gilbert Gosseyn, the superhuman amnesiac with a double brain, must pit his wits once more against the remorseless galactic dictator Enro the Red and the mysterious shadow-being known as The Follower. And he must do it while he is being hurled headlong through unimaginable distances in space, in time, and through alternate eternities to fend off the death and complete the rebirth of the Universe itself! Praise for John C. Wright “An exciting voice, adding richness to hard science fiction.” —David Brin, Hugo and Nebula Award–winning author of Existence

Contact has been made between other planets and Gilbert Gosseyn finds himself trying to stop a galactic war between Earth and Venus.

This exploration of a notorious mathematical problem is the work of the man who discovered the solution. Written by an award-winning professor at Stanford University, it employs intuitive explanations as well as detailed mathematical proofs in a self-contained treatment. This unique text and reference is suitable for students and professionals. 1966 edition. Copyright renewed 1994.

In this sequel to World of Null-A, Gilbert Gosseyn must learn to use both hisbrains and function in various bodies in order to save the universe from Enrothe Red.

In this book, the authors describe a continuum limit of the Toda ODE system, obtained by taking as initial data for the finite lattice successively finer discretizations of two smooth functions. Using the integrability of the finite Toda lattice, the authors adapt the method introduced by Lax and Levermore for the study of the small dispersion limit of the Korteweg de Vries equations to the case of the Toda lattice. A general class of initial data is considered which permits, in particular, the formation of shocks. A feature of the analysis in this book is an extensive use of techniques from the theory of Riemann-Hilbert problems.

Elise Morley is an expert on the past who's about to get a crash course in the future. For years, Elise has been donning corsets, sneaking into castles, and lying through her teeth to enforce the Place in Time Travel Agency's ten essential rules of time travel. Someone has to ensure that travel to the past isn't abused, and most days she welcomes the challenge of tracking down and retrieving clients who have run into trouble on their historical vacations. But when a dangerous secret organization kidnaps her and coerces her into jumping to the future on a high-stakes assignment, she's got more to worry about than just the time-space continuum. For the first time ever, she's the one out-of-date, out of place, and quickly running out of time.

This revised, updated edition provides a comprehensive and rigorous description of the application of Hamilton’s principle to continuous media. To introduce terminology and initial concepts, it begins with what is called the first problem of the calculus of variations. For both historical and pedagogical reasons, it first discusses the application of the principle to systems of particles, including conservative and non-conservative systems and systems with constraints. The foundations of mechanics of continua are introduced in the context of inner product spaces. With this basis, the application of Hamilton’s principle to the classical theories of fluid and solid mechanics are covered. Then recent developments are described, including materials with microstructure, mixtures, and continua with singular surfaces.

Concise classic by great mathematician and physicist deals with logic and mathematics of set and function, concept of number and the continuum. Bibliography. Originally published 1918.
