This visionary and engaging book provides a mathematical perspective on the fundamental ideas of numbers, space, life, evolution, the brain and the mind. The author suggests how a development of mathematical concepts in the spirit of category theory may lead to unravelling the mystery of the human mind and the design of universal learning algorithms. The book is divided into two parts, the first of which describes the ideas of great mathematicians and scientists, those who saw sparks of light in the dark sea of unknown. The second part, Memorandum Ergo, reflects on how mathematics can contribute to the understanding of the mystery of thought. It argues that the core of the human mind is a structurally elaborated object that needs a creation of a broad mathematical context for its understanding. Readers will discover the main properties of the expected mathematical objects within this context, called ERGO-SYSTEMS, and readers will see how these “systems” may serve as prototypes for design of universal learning computer programs. This is a work of great, poetical insight and is richly illustrated. It is a highly attractive read for all those who welcome a mathematical and scientific way of thinking about the world.

NEW YORK TIMES BESTSELLER • A TODAY SHOW #ReadWithJenna BOOK CLUB PICK • The unforgettable story of a daredevil female aviator determined to chart her own course in life, at any cost: an “epic trip—through Prohibition and World War II, from Montana to London to present-day Hollywood—and you’ll relish every minute” (People). After being rescued as infants from a sinking ocean liner in 1914, Marian and Jamie Graves are raised by their dissolute uncle in Missoula, Montana. There--after encountering a pair of barnstorming pilots passing through town in beat-up biplanes--Marian commences her lifelong love affair with flight. At fourteen she drops out of school and finds an unexpected and dangerous patron in a wealthy bootlegger who provides a plane and subsidizes her lessons, an arrangement that will haunt her for the rest of her life, even as it allows her to fulfill her destiny: circumnavigating the globe by flying over the North and South Poles. A century later, Hadley Baxter is cast to play Marian in a film that centers on Marian's disappearance in Antarctica. Vibrant, canny, disgusted with the claustrophobia of Hollywood, Hadley is eager to redefine herself after a romantic film franchise has imprisoned her in the grip of cult celebrity. Her immersion into the character of Marian unfolds, thrillingly, alongside Marian's own story, as the two women's fates--and their hunger for self-determination in vastly different geographies and times--collide. Epic and emotional, meticulously researched and gloriously told, Great Circle is a monumental work of art, and a tremendous leap forward for the prodigiously gifted Maggie Shipstead.

Bo Tully, sheriff of Blight County, Idaho, has dealt with small-town crime throughout his long, storied career. Now, contemplating retirement after years on the job, Tully is faced with perhaps his most perplexing case yet. When area bald eagles start getting picked off by a ghost-like killer, and when a prominent local rancher is murdered by an arrow with eagle fletching, things gets complicated fast. In this fast-paced whodunit, Tully has a vast array of suspects to chose from—including the rancher’s gorgeous, bird-loving wife who mysteriously leaves for a ranch in Mexico the day of the murder; the beautiful chef at the local house of ill repute, who is well-known as a budding ornithologist; and the ranch foreman, who is rumored to be having an affair with his boss’s widow. Will Tully put the pieces of the puzzle together, yet again? Will sending his dad, the former sheriff of Blight County, along with his number two man, down to Mexico help solve the mystery? And what about the mysterious large circles in the snow that Tully finds around the ranch—with no footprints leading in or out of the area? It all adds up to another engrossing series of twists and turns. And in the end, Tully gets his man . . . or woman . . . or does he?
