Book Description
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 Description
The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

Book Description
The mysterious connection between a teacher’s disappearance and an unsolved code in a children’s book is explored in this new novel from the “modern Agatha Christie” (The Sunday Times, London) and author of The Appeal. Forty years ago, Steven “Smithy” Smith found a copy of a famous children’s book by disgraced author Edith Twyford, its margins full of strange markings and annotations. When he showed it to his remedial English teacher Miss Iles, she believed that it was part of a secret code that ran through all of Twyford’s novels. And when she later disappeared on a class field trip, Smithy becomes convinced that she had been right. Now, out of prison after a long stretch, Smithy decides to investigate the mystery that has haunted him for decades. In a series of voice recordings on an old iPhone, Smithy alternates between visiting the people of his childhood and looking back on the events that later landed him in prison. But it soon becomes clear that Edith Twyford wasn’t just a writer of forgotten children’s stories. The Twyford Code holds a great secret, and Smithy may just have the key. “Filled with numerous clues, acrostics, and red herrings, this thrilling scavenger hunt for the truth is delightfully deceptive and thoroughly immersive” (Publishers Weekly, starred review).

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

Book Description
An examination of the many theories surrounding this enigmatic text, apparently written in code • Reveals the connections between this work and the Cathars, Roger Bacon, and John Dee • Explains the cryptanalysis methods used in attempts to break the code • Includes color images from the manuscript juxtaposed with other medieval writings Since its discovery by Wilfrid Voynich in an Italian monastery in 1912, the Voynich Manuscript has baffled scholars and cryptanalysists with its unidentifiable script and bizarre illustrations. Written in an unknown language or an as yet undecipherable code, this medieval manuscript contains hundreds of illustrations of unknown plants, cosmological charts, and inexplicable scenes of naked “nymphs” bathing in a green liquid that some interpret as a symbolic depiction of human reproduction and the joining of the soul with the body. Gerry Kennedy and Rob Churchill explore the mystery surrounding the Voynich Manuscript, examining the many existing theories about the possible authors of this work and the information it may contain. They trace the speculative history of the manuscript and reveal those who may be connected to it, including Roger Bacon, John Dee, and the Cathars. With the possibility that it may be a lost alchemical text or other esoteric work, this manuscript remains one of the most intriguing yet enigmatic documents ever to have come to light. Gerry Kennedy is a freelance writer and has produced a number of BBC Radio 4 programs, including one on the Voynich Manuscript in 2001. Rob Churchill is a professional writer who has written scripts for many production companies, including the BBC and Thames Television. Both authors were consultants for the BBC/Mentorn Films documentary The Voynich Mystery. They live in London.
