Available in PDF, EPUB and Kindle. Book excerpt: Requiring no more than a knowledge of high school mathematics and written in clear and accessible language, this book will give all readers a new insight into some of the most enjoyable and fascinating aspects of geometry. Everyone knows what a triangle is, yet very few people appreciate that the common three-sided figure holds many intriguing "secrets." For example, if a circle is inscribed in any random triangle and then three lines are drawn from the three points of tangency to the opposite vertices of the triangle, these lines will always meet at a common point-no matter what the shape of the triangle. This and many more interesting geometrical properties are revealed in this entertaining and illuminating book about geometry. Flying in the face of the common impression that mathematics is usually dry and intimidating, this book proves that this sometimes-daunting, abstract discipline can be both fun and intellectually stimulating. The authors, two veteran math educators, explore the multitude of surprising relationships connected with triangles and show some clever approaches to constructing triangles using a straightedge and a compass. Readers will learn how they can improve their problem-solving skills by performing these triangle constructions. The lines, points, and circles related to triangles harbor countless surprising relationships that are presented here in a very engaging fashion.

Download or read book Triangle written by Katharine Weber and published by Macmillan + ORM. This book was released on 2011-02-22 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Esther Gottesfeld is the last living survivor of the notorious 1911 Triangle Shirtwaist fire and has told her story countless times in the span of her lifetime. Even so, her death at the age of 106 leaves unanswered many questions about what happened that fateful day. How did she manage to survive the fire when at least 146 workers, most of them women, her sister and fiancé among them, burned or jumped to their deaths from the sweatshop inferno? Are the discrepancies in her various accounts over the years just ordinary human fallacy, or is there a hidden story in Esther's recollections of that terrible day? Esther's granddaughter Rebecca Gottesfeld, with her partner George Botkin, an ingenious composer, seek to unravel the facts of the matter while Ruth Zion, a zealous feminist historian of the fire, bores in on them with her own mole-like agenda. A brilliant, haunting novel about one of the most terrible tragedies in early-twentieth-century America, Triangle forces us to consider how we tell our stories, how we hear them, and how history is forged from unverifiable truths.
Download or read book Magnificent Mistakes in Mathematics written by Alfred S. Posamentier and published by Prometheus Books. This book was released on 2013-08-13 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two veteran math educators demonstrate how some "magnificent mistakes" had profound consequences for our understanding of mathematics' key concepts. In the nineteenth century, English mathematician William Shanks spent fifteen years calculating the value of pi, setting a record for the number of decimal places. Later, his calculation was reproduced using large wooden numerals to decorate the cupola of a hall in the Palais de la Découverte in Paris. However, in 1946, with the aid of a mechanical desk calculator that ran for seventy hours, it was discovered that there was a mistake in the 528th decimal place. Today, supercomputers have determined the value of pi to trillions of decimal places. This is just one of the amusing and intriguing stories about mistakes in mathematics in this layperson's guide to mathematical principles. In another example, the authors show that when we "prove" that every triangle is isosceles, we are violating a concept not even known to Euclid - that of "betweenness." And if we disregard the time-honored Pythagorean theorem, this is a misuse of the concept of infinity. Even using correct procedures can sometimes lead to absurd - but enlightening - results. Requiring no more than high-school-level math competency, this playful excursion through the nuances of math will give you a better grasp of this fundamental, all-important science.

Book excerpt: An instant New York Times Bestseller! “Unreasonably entertaining . . . reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning.” —The New York Times From the New York Times-bestselling author of How Not to Be Wrong—himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything. How should a democracy choose its representatives? How can you stop a pandemic from sweeping the world? How do computers learn to play Go, and why is learning Go so much easier for them than learning to read a sentence? Can ancient Greek proportions predict the stock market? (Sorry, no.) What should your kids learn in school if they really want to learn to think? All these are questions about geometry. For real. If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word "geometry"comes from the Greek for "measuring the world." If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. Shape shows us how.

Download or read book The Circle written by Alfred S. Posamentier and published by Prometheus Books. This book was released on 2016-08-23 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The circle has fascinated mathematicians since ancient times. This entertaining book describes in layperson’s terms the many intriguing properties of this fundamental shape. If math has intimidated you, this may be the ideal book to help you appreciate the discipline through one of its most important elements. The authors begin with a brief review of the basic properties of the circle and related figures. They then show the many ways in which the circle manifests itself in the field of geometry—leading to some amazing relationships and truly important geometric theorems. In addition, they explore remarkable circle constructions and demonstrate how all constructions in geometry that usually require an unmarked straightedge and a compass can also be done with the compass alone. Among other things, the reader will learn that circles can generate some unusual curves – many even quite artistic. Finally, the role of circles in art and architecture and a discussion of the circle’s place on the sphere bring "full circle" this presentation of a key element of geometry.

Book excerpt: Mike Bara, author of Ancient Aliens on the Moon, takes a hard look at the Bermuda Triangle. For decades, no single place has intrigued the world more than the baffling mystery of the Bermuda Triangle. Hundreds of ships, planes and yachts have disappeared in the dark, mysterious waters between Bermuda and Florida, far more than in any other part of the world. Ships have vanished without a trace only to magically reappear years later in good order but minus their crews, almost as if the intervening years had not even passed–for them. Yachts and ocean liners have gone missing in good weather with no explanation. Pilots have reported bizarre problems with their instruments as compasses and guidance systems have spun inexplicably out of control over the shadowy waters of the Triangle. Entire squadrons of military aircraft have disappeared off of radarscopes in clear weather and with no forewarning. Others have experienced strange magnetic anomalies and otherworldly encounters with mysterious craft and unrecognizable energetic fields. Explanations range from alien encounters to rogue waves to twisting unnatural funnel spouts caused by submerged civilizations left over from the days of Atlantis. New York Times bestselling author Mike Bara investigates these and other mysteries of the Bermuda Triangle in his new book The Triangle. Find out what really happened to Flight 19, the Navy training flight that last reported “they look like they’re from outer space” over the Triangle. Examine the undersea ruins of a lost civilization just off the island of Bimini and the strange stone road that leads directly into the deep waters of the Triangle. Examine the case of the Cotopaxi, the ore ship lost at sea only to reappear decades later off the coast of Cuba, far beyond where it was last sighted in the Triangle’s maritime shipping lanes. These and other enigmatic cases will be stripped open and laid bare before the light of history as the reader is carried on a journey to the world’s most frightening and impenetrable mystery–The Bermuda Triangle.
