A complete and accessible history of computer science, beginning with Charles Babbage in 1819.

As a field, computer science occupies a unique scientific space, in that its subject matter can exist in both physical and abstract realms. An artifact such as software is both tangible and not, and must be classified as something in between, or "liminal." The study and production of liminal artifacts allows for creative possibilities that are, and have been, possible only in computer science. In It Began with Babbage, computer scientist and writer Subrata Dasgupta examines the distinct history of computer science in terms of its creative innovations, reaching back to Charles Babbage in 1819. Since all artifacts of computer science are conceived with a use in mind, the computer scientist is not concerned with the natural laws that govern disciplines like physics or chemistry; instead, the field is more concerned with the concept of purpose. This requirement lends itself to a type of creative thinking that, as Dasgupta shows us, has exhibited itself throughout the history of computer science. More than any other, computer science is the science of the artificial, and has a unique history to accompany its unique focus. The book traces a path from Babbage's Difference Engine in the early 19th century to the end of the 1960s by when a new academic discipline named "computer science" had come into being. Along the way we meet characters like Babbage and Ada Lovelace, Turing and von Neumann, Shannon and Chomsky, and a host of other people from a variety of backgrounds who collectively created this new science of the artificial. And in the end, we see how and why computer science acquired a nature and history all of its own.

"Drawing on previously unused archival material, The Difference Engine is a tale of both Babbage's nineteenth-century quest to build a calculating engine and its twentieth-century sequel. For in 1991, Babbage's vision was finally realized, at least in part, by the completion at the Science Museum in London of the first full-sized Babbage engine, finished in time for the 200th anniversary of Babbage's birth. The two quests are mutually illuminating and are recounted here by the then Curator of Computing, Doron Swade - one of the main protagonists of the successful resumption of Babbage's extraordinary work."--BOOK JACKET.

This is not a book about the history of computing or the history of information. Instead, it is a meta-historical book about the research and writing of these types of history. The formal presentation of historical research in the form of a publication often hides the process by which the topic was selected, boundaries were drawn, evidence was selected, analytic approach was chosen and applied, results were presented, how this work fits into a larger body of scholarship, the implicit goals and biases of the author, and many other similar issues. This process of learning about the various ways to carry out computer history or information history can be enriched by this collection of reflective essays by experienced scholars, discussing the craft that they practice. This is a book that concerns both computer history and information history. The first scholarship in computer history by professionally trained scholars began to appear in the 1970s, so we are approaching a half century of research and publication in this area. The field has generated numerous pieces of exemplary scholarship from various perspectives such as intellectual history of individual technologies, business histories of firms, economic histories of market sectors, externalist histories of funding and professionalization, and so on. However, the field continues to evolve, especially as computing and communication technologies have drawn together in the form of the Internet and social media; and with them a new set of scholars is participating, drawn not only from the history of science and technology, but also from the communication and media studies fields. Powerful theories, approaches, and frameworks are being increasingly drawn more widely from both the humanities and the social sciences to inform the practice of computer history. The scholars in this volume look at what’s happened, what’s happening now, and where historical scholarship in these disciplines is headed.

Examines the life and contributions of the English mathematician and inventor, whose work with calculating machines caused him to be called the father of the modern computer.

This work presents a series of dramatic discoveries never before made public. Starting from a collection of simple computer experiments---illustrated in the book by striking computer graphics---Wolfram shows how their unexpected results force a whole new way of looking at the operation of our universe. Wolfram uses his approach to tackle a remarkable array of fundamental problems in science: from the origin of the Second Law of thermodynamics, to the development of complexity in biology, the computational limitations of mathematics, the possibility of a truly fundamental theory of physics, and the interplay between free will and determinism.

1855: The Industrial Revolution is in full and inexorable swing, powered by steam-driven cybernetic Engines. Charles Babbage perfects his Analytical Engine and the computer age arrives a century ahead of its time. And three extraordinary characters race toward a rendezvous with history—and the future: Sybil Gerard—a fallen woman, politician’s tart, daughter of a Luddite agitator Edward “Leviathan” Mallory—explorer and paleontologist Laurence Oliphant—diplomat, mystic, and spy. Their adventure begins with the discovery of a box of punched Engine cards of unknown origin and purpose. Cards someone wants badly enough to kill for…. Part detective story, part historical thriller, The Difference Engine is the collaborative masterpiece by two of the most acclaimed science fiction authors writing today. Provocative, compelling, intensely imagined, it is a startling extension of Gibson’s and Sterling’s unique visions—and the beginning of movement we know today as “steampunk!”
