An Imaginary Tale by Paul J. Nahin Pdf

Today complex numbers have such widespread practical use--from electrical engineering to aeronautics--that few people would expect the story behind their derivation to be filled with adventure and enigma. In An Imaginary Tale, Paul Nahin tells the 2000-year-old history of one of mathematics' most elusive numbers, the square root of minus one, also known as i. He recreates the baffling mathematical problems that conjured it up, and the colorful characters who tried to solve them. In 1878, when two brothers stole a mathematical papyrus from the ancient Egyptian burial site in the Valley of Kings, they led scholars to the earliest known occurrence of the square root of a negative number. The papyrus offered a specific numerical example of how to calculate the volume of a truncated square pyramid, which implied the need for i. In the first century, the mathematician-engineer Heron of Alexandria encountered I in a separate project, but fudged the arithmetic; medieval mathematicians stumbled upon the concept while grappling with the meaning of negative numbers, but dismissed their square roots as nonsense. By the time of Descartes, a theoretical use for these elusive square roots--now called "imaginary numbers"--was suspected, but efforts to solve them led to intense, bitter debates. The notorious i finally won acceptance and was put to use in complex analysis and theoretical physics in Napoleonic times. Addressing readers with both a general and scholarly interest in mathematics, Nahin weaves into this narrative entertaining historical facts and mathematical discussions, including the application of complex numbers and functions to important problems, such as Kepler's laws of planetary motion and ac electrical circuits. This book can be read as an engaging history, almost a biography, of one of the most evasive and pervasive "numbers" in all of mathematics.

Imaginary friend Budo narrates this heartwarming story of love, loyalty, and the power of the imagination—the perfect read for anyone who has ever had a friend . . . real or otherwise Budo is lucky as imaginary friends go. He's been alive for more than five years, which is positively ancient in the world of imaginary friends. But Budo feels his age, and thinks constantly of the day when eight-year-old Max Delaney will stop believing in him. When that happens, Budo will disappear. Max is different from other children. Some people say that he has Asperger's Syndrome, but most just say he's "on the spectrum." None of this matters to Budo, who loves Max and is charged with protecting him from the class bully, from awkward situations in the cafeteria, and even in the bathroom stalls. But he can't protect Max from Mrs. Patterson, the woman who works with Max in the Learning Center and who believes that she alone is qualified to care for this young boy. When Mrs. Patterson does the unthinkable and kidnaps Max, it is up to Budo and a team of imaginary friends to save him—and Budo must ultimately decide which is more important: Max's happiness or Budo's very existence. Narrated by Budo, a character with a unique ability to have a foot in many worlds—imaginary, real, child, and adult— Memoirs of an Imaginary Friend touches on the truths of life, love, and friendship as it races to a heartwarming . . . and heartbreaking conclusion.

That storyline drives Hell of a Book and is the scaffolding of something much larger and more urgent: Mott’s novel also tells the story of Soot, a young Black boy living in a rural town in the recent past, and The Kid, a possibly imaginary child who appears to the author on his tour. As these characters’ stories build and converge, they astonish. For while this heartbreaking and magical book entertains and is at once about family, love of parents and children, art and money, it’s also about the nation’s reckoning with a tragic police shooting playing over and over again on the news. And with what it can mean to be Black in America. Who has been killed? Who is The Kid? Will the author finish his book tour, and what kind of world will he leave behind? Unforgettably told, with characters who burn into your mind and an electrifying plot ideal for book club discussion, Hell of a Book is the novel Mott has been writing in his head for the last ten years. And in its final twists, it truly becomes its title.
