The Secrets of Triangles by Alfred S. Posamentier,Ingmar Lehmann Pdf

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.

Magnificent Mistakes in Mathematics by Alfred S. Posamentier,Ingmar Lehmann Pdf

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.

Triangle by Katharine Weber Pdf

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.

Becoming Brilliant by Roberta Michnick Golinkoff,Kathy Hirsh-Pasek Pdf

In just a few years, today’s children and teens will forge careers that look nothing like those that were available to their parents or grandparents. While the U.S. economy becomes ever more information-driven, our system of education seems stuck on the idea that “content is king,” neglecting other skills that 21st century citizens sorely need. Becoming Brilliant offers solutions that parents can implement right now. Backed by the latest scientific evidence and illustrated with examples of what’s being done right in schools today, this book introduces the 6Cs—collaboration, communication, content, critical thinking, creative innovation, and confidence—along with ways parents can nurture their children’s development in each area.

Mathematics Entertainment For The Millions by Alfred S Posamentier Pdf

'The physical form of this new title is pleasing, including good paper, readable font, and durable binding … The book is not a collection of practical ideas. Rather, it is intended for those curious about pure mathematical tidbits. The flavor is light, as opposed to pedantic. Among the numerous books of this type, this title is significantly better than most. It should be considered for private collections and for libraries that can afford to serve a small, unique readership.Summing Up: Recommended. General readers.'CHOICEThis book demonstrates to the general audience that mathematics can be entertaining and fun, rather than the sad reputation it has gained over decades from uninspired school instruction that is often devoid of enrichment or motivational considerations.The book is designed in such a way that a reader will need almost no special preparation in mathematics, but to recall some of the most basic concepts that were taught at the lower-secondary-grade level.Yet, by the same token, the book will hopefully open up doors for those less motivated in mathematics — to interest readers to investigate some of the topics presented and thereby enhance their knowledge of mathematics — something most general readers will not initially find possible, but we hope will be an end product of this book.
