A Three Book Problem

The seventh installment in a “fast, fun” cozy mystery series “full of Sherlockian lore” and starring “a charming, intelligent heroine as observant as The Great Detective Himself” (Carolyn Hart, New York Times–bestselling author) Sherlockian bookshop manager and frequent amateur sleuth Gemma Doyle is back on the case when a poisoned dart ends in demise . . . It’s a crisp, early October weekend, and business is slowing down as fall descends at the Sherlock Holmes Bookshop and Emporium and adjacent Mrs. Hudson’s Tea Room. Wealthy philanthropist and prominent Sherlockian David Masterson has rented Suffolk Gardens House, where he plans to entertain his friends in a traditional English country house weekend. As the chosen caterers, Jayne Wilson and Gemma Doyle get to work preparing lavish meals and setting up Sherlockian books and props for entertainment. Meanwhile, police detective Ryan Ashburton has taken time away from his duties to assist in the kitchen. It quickly becomes apparent that David’s guests don't like each other—or their host. Plus, some of them aren't even acquainted with the adventures of the Great Detective. Before Gemma can ponder their relationships a poisoned dart sails through the window of the library, presenting Gemma Doyle with a three-book problem.

Set in the universe of the New York Times bestselling Three-Body Problem trilogy, The Redemption of Time continues Cixin Liu’s multi-award-winning science fiction saga. This original story by Baoshu—published with Liu’s support—envisions the aftermath of the conflict between humanity and the extraterrestrial Trisolarans. In the midst of an interstellar war, Yun Tianming found himself on the front lines. Riddled with cancer, he chose to end his life, only to find himself flash frozen and launched into space where the Trisolaran First Fleet awaited. Captured and tortured beyond endurance for decades, Yun eventually succumbed to helping the aliens subjugate humanity in order to save Earth from complete destruction. Granted a healthy clone body by the Trisolarans, Yun has spent his very long life in exile as a traitor to the human race. Nearing the end of his existence at last, he suddenly receives another reprieve—and another regeneration. A consciousness calling itself The Spirit has recruited him to wage battle against an entity that threatens the existence of the entire universe. But Yun refuses to be a pawn again and makes his own plans to save humanity’s future... At the Publisher's request, this title is being sold without Digital Rights Management Software (DRM) applied.

Poincare's famous memoir on the three body problem arose from his entry in the competition celebrating the 60th birthday of King Oscar of Sweden and Norway. His essay won the prize and was set up in print as a paper in Acta Mathematica when it was found to contain a deep and critical error. In correcting this error Poincare discovered mathematical chaos, as is now clear from June Barrow-Green's pioneering study of a copy of the original memoir annotated by Poincare himself, recently discovered in the Institut Mittag-Leffler in Stockholm. Poincare and the Three Body Problem opens with a discussion of the development of the three body problem itself and Poincare's related earlier work. The book also contains intriguing insights into the contemporary European mathematical community revealed by the workings of the competition. After an account of the discovery of the error and a detailed comparative study of both the original memoir and its rewritten version, the book concludes with an account of the final memoir's reception, influence and impact, and an examination of Poincare's subsequent highly influential work in celestial mechanics.

Cambridge, 1888. When schoolmistress Vanessa Duncan learns of a murder at St John's College, little does she know that she will become deeply entangled in the mystery. Dr Geoffrey Akers, Fellow in Pure Mathematics, has been found dead, struck down by a violent blow to the head. What could provoke such a brutal act? Vanessa, finding herself in amongst Cambridge's brightest scholarly minds, discovers that the motive may lie in mathematics itself. Drawn closer to the case by a blossoming friendship with mathematician Arthur Weatherburn, Vanessa begins to investigate. When she learns of Sir Isaac Newton's elusive 'n-body problem' and the prestigious prize offered to anyone with a solution, things begin to make sense. But with further deaths occurring and the threat of an innocent man being condemned, Vanessa must hurry with her calculations . . .

In The Dark Forest, Earth is reeling from the revelation of a coming alien invasion-in just four centuries' time. The aliens' human collaborators may have been defeated, but the presence of the sophons, the subatomic particles that allow Trisolaris instant access to all human information, means that Earth's defense plans are totally exposed to the enemy. Only the human mind remains a secret. This is the motivation for the Wallfacer Project, a daring plan that grants four men enormous resources to design secret strategies, hidden through deceit and misdirection from Earth and Trisolaris alike. Three of the Wallfacers are influential statesmen and scientists, but the fourth is a total unknown. Luo Ji, an unambitious Chinese astronomer and sociologist, is baffled by his new status. All he knows is that he's the one Wallfacer that Trisolaris wants dead.

The $3x+1$ problem, or Collatz problem, concerns the following seemingly innocent arithmetic procedure applied to integers: If an integer $x$ is odd then “multiply by three and add one”, while if it is even then “divide by two”. The $3x+1$ problem asks whether, starting from any positive integer, repeating this procedure over and over will eventually reach the number 1. Despite its simple appearance, this problem is unsolved. Generalizations of the problem are known to be undecidable, and the problem itself is believed to be extraordinarily difficult. This book reports on what is known on this problem. It consists of a collection of papers, which can be read independently of each other. The book begins with two introductory papers, one giving an overview and current status, and the second giving history and basic results on the problem. These are followed by three survey papers on the problem, relating it to number theory and dynamical systems, to Markov chains and ergodic theory, and to logic and the theory of computation. The next paper presents results on probabilistic models for behavior of the iteration. This is followed by a paper giving the latest computational results on the problem, which verify its truth for $x < 5.4 cdot 10^{18}$. The book also reprints six early papers on the problem and related questions, by L. Collatz, J. H. Conway, H. S. M. Coxeter, C. J. Everett, and R. K. Guy, each with editorial commentary. The book concludes with an annotated bibliography of work on the problem up to the year 2000.

From the New York Times bestselling author of the Three-Body Trilogy, Cixin Liu's Ball Lightning is the story of what happens when the beauty of scientific inquiry runs up against the drive to harness new discoveries with no consideration of their possible consequences. When Chen’s parents are incinerated before his eyes by a blast of ball lightning, he devotes his life to cracking the secret of this mysterious natural phenomenon. His search takes him to stormy mountaintops, an experimental military weapons lab, and an old Soviet science station. The more he learns, the more he comes to realize that ball lightning is just the tip of an entirely new frontier. While Chen’s quest for answers gives purpose to his lonely life, it also pits him against soldiers and scientists with motives of their own: a beautiful army major with an obsession with dangerous weaponry, and a physicist who has no place for ethical considerations in his single-minded pursuit of knowledge.
