Download or read book The Secret Code written by Priya Hemenway and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Verlagsinfo: The Divine Proportion reveals a number of simple patterns: It is seen in the seed patterns of fruits, the family tree of bees, the pyramids of Egypt, Gothic cathedrals, Renaissance paintings, the human body, shells ... the list is endless. Mathematicians use the Greek symbol to represent the Divine Proportion and equate it to a number that is defined by the ratio (1 + 5) / 2 or 1.6180339.... Numbers do little, however, in describing this unique ratio that is found everywhere in nature and for 2500 years has been an aesthetic guide in art and architecture. Beginning with calculations found on clay tablets in ancient Babylon, the story of Divine Proportion can be traced alongside the history of numbers to the fractals of the digital age. As its many forms unfold we uncover the Golden Rectangle in the Parthenon, Golden Spirals in the human inner ear, a Golden Angle in the petal patterns of a rose, and the Fibonacci numbers in lilies, daisies, pineapples, and in our own DNA. With its natural balance and elegant beauty, the Divine Proportion is a perpetual reminder that our hope for regeneration and continuity lies in realizing the meaningful and harmonious relationship of all the parts to the whole. This book deals with the Divine Proportion, a secret code that rules art, nature, and science. It is known by many names: Golden Mean, Sacred Cut and Phi are only a few; and it is not by chance that the Divine Proportion was given its name. It has been called divine because over thousands of years it has been deemed to be so.

Book excerpt: Peter Farrow is a slave. He's grown up with his family on Dover Plantation, South Carolina where he does small jobs. When he's not working, Peter likes to play with the other slave's children, or go fishing with the master's daughter, Emily. Sometimes, he even gets to sit in on Emily's school lessons and learn to read. Since Peter is almost twelve, it's time for him to learn a trade. The master has agreed for Peter to apprentice with Samuel, the plantation's carpenter. Peter is happy he won't have to fetch and carry anymore, or work in the dairy, churning butter. However, Peter's mother decides it's time he learns the family's secret. She and her husband have been active in the Underground Railroad, helping slaves escape. They use secret codes sewn into quilts and wagons with a secret hiding place. When traveling to other plantations doing work for the master, Peter's father transports runaways in the wagon's false bottom. Until now, Peter has been too young to keep a secret of this magnitude. But John, the cruel overseer, has other plans for Peter. He wants Peter out in the fields, doing the backbreaking work of a grownup slave, where Peter is close enough to feel his whip. When Peter comes between Samuel and the sadistic overseer's whip, Peter makes a terrible enemy. Overseer John alerts the master about Emily spending too much time with Peter. When the two friends are caught together multiple times, the master decides to sell Peter down south. Distraught, Peter's mother and father decide to "transport" him away from Dover Plantation before he can be sold. Using the secret quilt codes, other runaways join Peter's family as they make their way to the first safe house on the Underground Railroad. When they arrive, Peter's parents make the hard decision to send him on to Canada with Samuel while they remain in South Carolina, helping more runaways escape to freedom. A poignant tale of an enslaved family making the difficult decision to "do their part" for their kinsmen instead of running together toward their own freedom.

Book Synopsis The Language of Thieves: My Family's Obsession with a Secret Code the Nazis Tried to Eliminate by : Martin Puchner
Download or read book The Language of Thieves: My Family's Obsession with a Secret Code the Nazis Tried to Eliminate written by Martin Puchner and published by W. W. Norton & Company. This book was released on 2020-10-13 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tracking an underground language and the outcasts who depended on it for their survival. Centuries ago in middle Europe, a coded language appeared, scrawled in graffiti and spoken only by people who were "wiz" (in the know). This hybrid language, dubbed Rotwelsch, facilitated survival for people in flight—whether escaping persecution or just down on their luck. It was a language of the road associated with vagabonds, travelers, Jews, and thieves that blended words from Yiddish, Hebrew, German, Romani, Czech, and other European languages and was rich in expressions for police, jail, or experiencing trouble, such as "being in a pickle." This renegade language unsettled those in power, who responded by trying to stamp it out, none more vehemently than the Nazis. As a boy, Martin Puchner learned this secret language from his father and uncle. Only as an adult did he discover, through a poisonous 1930s tract on Jewish names buried in the archives of Harvard’s Widener Library, that his own grandfather had been a committed Nazi who despised this "language of thieves." Interweaving family memoir with an adventurous foray into the mysteries of language, Puchner crafts an entirely original narrative. In a language born of migration and survival, he discovers a witty and resourceful spirit of tolerance that remains essential in our volatile present.
