A “marvelous history”* of medieval Europe, from the bubonic plague and the Papal Schism to the Hundred Years’ War, by the Pulitzer Prize–winning author of The Guns of August *Lawrence Wright, author of The End of October, in The Wall Street Journal The fourteenth century reflects two contradictory images: on the one hand, a glittering age of crusades, cathedrals, and chivalry; on the other, a world plunged into chaos and spiritual agony. In this revelatory work, Barbara W. Tuchman examines not only the great rhythms of history but the grain and texture of domestic life: what childhood was like; what marriage meant; how money, taxes, and war dominated the lives of serf, noble, and clergy alike. Granting her subjects their loyalties, treacheries, and guilty passions, Tuchman re-creates the lives of proud cardinals, university scholars, grocers and clerks, saints and mystics, lawyers and mercenaries, and, dominating all, the knight—in all his valor and “furious follies,” a “terrible worm in an iron cocoon.” Praise for A Distant Mirror “Beautifully written, careful and thorough in its scholarship . . . What Ms. Tuchman does superbly is to tell how it was. . . . No one has ever done this better.”—The New York Review of Books “A beautiful, extraordinary book . . . Tuchman at the top of her powers . . . She has done nothing finer.”—The Wall Street Journal “Wise, witty, and wonderful . . . a great book, in a great historical tradition.”—Commentary

Proportional Optimization and Fairness is a long-needed attempt to reconcile optimization with apportionment in just-in-time (JIT) sequences and find the common ground in solving problems ranging from sequencing mixed-model just-in-time assembly lines through just-in-time batch production, balancing workloads in event graphs to bandwidth allocation internet gateways and resource allocation in computer operating systems. The book argues that apportionment theory and optimization based on deviation functions provide natural benchmarks for a process, and then looks at the recent research and developments in the field. Individual chapters look at the theory of apportionment and just-in-time sequences; minimization of just-in-time sequence deviation; optimality of cyclic sequences and the oneness; bottleneck minimization; competition-free instances, Fraenkel’s Conjecture, and optimal admission sequences; response time variability; applications to the Liu-Layland Problem and pinwheel scheduling; temporal capacity constraints and supply chain balancing; fair queuing and stride scheduling; and smoothing and batching.

Set against the backdrop of a remote location in the throes of rapid development, Nik Delaney leaves a respected career in wildlife biology to return home to Wyoming. In the Rocky Mountain winter, every relationship Nik has wears even thinner as she cares for her aging father, faces a crumbling marriage, and parents Finn, the son of her antagonistic brother. Then Zolo, her foster dog, runs away. Nik’s search for Zolo in the vast and unforgiving landscape introduces her to the eccentric residents of the high sagebrush, including a rancher trying to run an ecolodge in oil country and a displaced herd of wild mustangs led by a mare called Tess. Zolo and Tess learn to rely on each other to thrive, but even with her father’s life at stake, Nik resists relying on the desert’s scattered community. This story of loyalty and deception in western Wyoming expands our sense of who we choose to consider family.
