In his first book since the bestselling Fermat's Enigma, Simon Singh offers the first sweeping history of encryption, tracing its evolution and revealing the dramatic effects codes have had on wars, nations, and individual lives. From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy. Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world's most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

From the bestselling author of the acclaimed Chaos and Genius comes a thoughtful and provocative exploration of the big ideas of the modern era: Information, communication, and information theory. Acclaimed science writer James Gleick presents an eye-opening vision of how our relationship to information has transformed the very nature of human consciousness. A fascinating intellectual journey through the history of communication and information, from the language of Africa’s talking drums to the invention of written alphabets; from the electronic transmission of code to the origins of information theory, into the new information age and the current deluge of news, tweets, images, and blogs. Along the way, Gleick profiles key innovators, including Charles Babbage, Ada Lovelace, Samuel Morse, and Claude Shannon, and reveals how our understanding of information is transforming not only how we look at the world, but how we live.

"Music and silence-how I detest them both!"Screwtape, under-secretary to the devil, The Screwtape Letters by C. S. LewisIt's easy to see why the enemies of mankind would hate and fear both sacred silence and sacred music. Both bring joy, spur contemplation, and draw the soul nearer to the Lord. Both have been part of our private prayer as well as our communal liturgy for thousands of years.The Psalms-biblical songs of praise, supplication, and wonder-have been sung for three thousand years. Naturally, Jesus, His disciples, and later the early Christian community also sang hymns (from the Greek word meaning "songs of praise"), as The New Testament makes clear. We sing because we love, and sung praise elevates our words, takes them out of the realm of the commonplace, and increases our joy. The holy pleasure of singing to God involves the entire person-spirit, heart, mind, and body-and unites us not only with the Divine but also with one another as a worshiping community.This collection of hymns for the singing Catholic congregation exemplifies the best of the genre. These songs are religiously orthodox, beautiful, sacred, and-for the most part-familiar. But here you will also find worthy hymn tunes and texts that are new to you.We present this book to propose not that hymns replace the proper chants for that days Mass* but live happily alongside them. In most instances the proper chants for processions are the prerogative of cantors and choirs and, as they change very day as part of the Mass aren't practical to be sung by the congregation. Hymns, on the other hand, belong to all the faithful and serve as a key means of the "active participation" spoken of in Vatican II's Constitution on the Sacred Liturgy. Hymns have been sung as an important part of the Liturgy of the Hours for century upon century, so they are nothing new, new only to be sung at Mass. "To promote active participation, the people should be encouraged to take part by means of acclamations, responses, psalmody, antiphons, and songs, as well as by actions, gestures, and bodily attitudes. And at the proper times all should observe a reverent silence."Sacrosanctum Concilium (Constitution on the Sacred Liturgy, Vatican II, 1963), Paragraph 30In a parish where the scriptures are sung, the introit will accompany the procession of the ministers and the cross. Clergy, choir, and people can then sing a congregational hymn. The same is true at offertory and Communion: hymns can follow the proper chants. And at the conclusion of Mass, a suitable hymn can send the people forth with the praise of Almighty God on their lips.May this book bring joy to all who sing from it! What is the source of the Sung Antiphons for the Roman liturgy Mass?The proper texts of the Antiphons of the Roman liturgy may be found in: Graduale Romanum; English translations of these texts are also widely available. The antiphons from the Roman Missal, third edition, may also serve as proper texts.
