The story of information begins in a time profoundly unlike our own, when every thought and utterance vanishes as soon as it is born. From the invention of scripts and alphabets to the long-misunderstood talking drums of Africa, Gleick tells the story of information technologies that changed the very nature of human consciousness. He provides portraits of the key figures contributing to the inexorable development of our modern understanding of information: Charles Babbage, the idiosyncratic inventor of the first great mechanical computer; Ada Byron, the brilliant and doomed daughter of the poet, who became the first true programmer; pivotal figures like Samuel Morse and Alan Turing; and Claude Shannon, the creator of information theory itself. And then the information age arrives. Citizens of this world become experts willy-nilly: aficionados of bits and bytes. And we sometimes feel we are drowning, swept by a deluge of signs and signals, news and images, blogs and tweets. The Information is the story of how we got here and where we are heading.

    For instance, in treating of the actual working of the exchange standard, I have contented myself with a general treatment just sufficiently detailed to enable the reader to follow the criticism I have offered. If more details are desired they are given in all their amplitude in other treatises. To have reproduced them would have been a work of supererogation; besides it would have only obscured the general trend of my argument. But in other respects, I have been obliged to take a wider historical sweep than has been done by other writers. The existing treatises on Indian currency do not give any idea, at least an adequate idea, of the circumstances which led to the reforms of 1893. I think that a treatment of the early history is quite essential to furnish the reader with a perspective in order to enable him to judge for himself the issues involved in the currency crisis and also of the solutions offered. In view of this, I have gone into that most neglected period of Indian currency extending from 1800 to 1893. Not only have other writers begun abruptly the story of the exchange standard, but they have popularised the notion that the exchange standard is the standard originally contemplated by the Government of India. I find that this is a gross error. Indeed, the most interesting point about Indian currency is the way in which the gold standard came to be transformed into a gold exchange standard. Some old, but by now forgotten, facts had therefore, to be recounted to expose this error.

    

    The book covers the syllabus for Engineering chemistry course offered to first year B.E/B.Tech students of various India University

    The text begins with a discussion of the real number system as a complete ordered field. (Dedekind's construction is now treated in an appendix to Chapter I.) The topological background needed for the development of convergence, continuity, differentiation and integration is provided in Chapter 2. There is a new section on the gamma function, and many new and interesting exercises are included. This text is part of the Walter Rudin Student Series in Advanced Mathematics.

    The text is divided into two main parts: Part 1 contains conversations based on common daily situations, while Part 2 emphasizes particular structural or lexical features of the language. This book contains a large number of exercises designed in a programmed fashion; all the words or sentences are presented at the left of the page and the expected responses are given at the right. The book is ideal for home study and would be extremely useful to all those interested in improving their conversational skills.

    Majeed's father was rich once, so could send him to a school in the distant town, although he was not very good at studies. Suhra's father on the other hand had trouble making both ends meet. Even then he wanted to send his daughter, who was good at studies to the school. But after her father's death, all her hopes of further studies was ruined. Majeed begs his father to sponsor Suhra's education, but he refuses. Majeed leaves home after a skirmish with his father, and wanders over distant lands for a long time before returning home. On his return, he finds that his family's former affluence is all gone, and that his beloved Suhra has married someone else. He is grief struck at the loss of love, and this is when Suhra turns up at his home. She is a shadow of her former self. The beautiful, sunshiny, vibrant Suhra of old is now a woman worn out by life, battered hard by a loveless marriage to an abusive husband. Majeed commands her, "Suhra, don't go back!" and she stays.

    Along the tidal rivers of Malaysia, thousands of fireflies congregate and flash in unison; the moon spins in perfect resonance with its orbit around the earth; our hearts depend on the synchronous firing of ten thousand pacemaker cells. While the forces that synchronize the flashing of fireflies may seem to have nothing to do with our heart cells, there is in fact a deep connection. Synchrony is a science in its infancy, and Strogatz is a pioneer in this new frontier in which mathematicians and physicists attempt to pinpoint just how spontaneous order emerges from chaos. From underground caves in Texas where a French scientist spent six months alone tracking his sleep-wake cycle, to the home of a Dutch physicist who in 1665 discovered two of his pendulum clocks swinging in perfect time, this fascinating book spans disciplines, continents, and centuries. Engagingly written for readers of books such as Chaos and The Elegant Universe, Sync is a tour-de-force of nonfiction writing.

    In The Universe and the Teacup, K. C. Cole demystifies mathematics and shows us-with humor and wonderfully accessible stories-why math need not be frightening. Using the O. J. Simpson trial, the bell curve, and Emmy Noether, the nineteenth-century woman scientist whose work was essential for Einstein's theory of relativity, Cole helps us see that more than just being a tool, math is a key to understanding the beauty of everything from rainbows to relativity.
