Available in PDF, EPUB and Kindle. Book excerpt: Learn about the secret code that is DNA in this vibrant and informative picture book! There's a secret code inside you, a code called DNA. A code that tells your body's cells what they should do each day. It looks like twisted ladders, or tiny, twirling noodles. It makes us into people, instead of into poodles. Why can't humans breathe underwater? Why are some people tall and others short? Why do we resemble our parents and grandparents? This book explores all this and more in flowing, rhyming text, explaining cells, DNA, and genetics in a way that is simple and easy for children to understand. Colorful and brilliantly illustrated, The Secret Code Inside You illustrates that while DNA may be the blueprint for how a person looks, what you choose to do with your body is entirely up to you!

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.

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.
