In 1936, when he was just twenty-four years old, Alan Turing wrote a remarkable paper in which he outlined the theory of computation, laying out the ideas that underlie all modern computers. This groundbreaking and powerful theory now forms the basis of computer science. In Turing’s Vision, Chris Bernhardt explains the theory, Turing’s most important contribution, for the general reader. Bernhardt argues that the strength of Turing’s theory is its simplicity, and that, explained in a straightforward manner, it is eminently understandable by the nonspecialist.
Between 1959 and 1989, Soviet scientists and officials made numerous attempts to network their nation—to construct a nationwide computer network. None of these attempts succeeded, and the enterprise had been abandoned by the time the Soviet Union fell apart. Meanwhile, ARPANET, the American precursor to the Internet, went online in 1969. Why did the Soviet network, with top-level scientists and patriotic incentives, fail while the American network succeeded?
The daguerreotype, invented in France, came to America in 1839. By 1851, this early photographic method had been improved by American daguerreotypists to such a degree that it was often referred to as “the American process.” The daguerreotype—now perhaps mostly associated with stiffly posed portraits of serious-visaged nineteenth-century personages—was an extremely detailed photographic image, produced though a complicated process involving a copper plate, light-sensitive chemicals, and mercury fumes.
Conceived in 1943, completed in 1945, and decommissioned in 1955, ENIAC (the Electronic Numerical Integrator and Computer) was the first general-purpose programmable electronic computer. But ENIAC was more than just a milestone on the road to the modern computer.
For more than a century, the interplay between private, investor-owned electric utilities and government regulators has shaped the electric power industry in the United States. Provision of an essential service to largely dependent consumers invited government oversight and ever more sophisticated market intervention. The industry has sought to manage, co-opt, and profit from government regulation. In The Power Brokers, Jeremiah Lambert maps this complex interaction from the late nineteenth century to the present day.
We may imagine the digital cloud as placeless, mute, ethereal, and unmediated. Yet the reality of the cloud is embodied in thousands of massive data centers, any one of which can use as much electricity as a midsized town. Even all these data centers are only one small part of the cloud. Behind that cloud-shaped icon on our screens is a whole universe of technologies and cultural norms, all working to keep us from noticing their existence. In this book, Tung-Hui Hu examines the gap between the real and the virtual in our understanding of the cloud.
Computer graphics (or CG) has changed the way we experience the art of moving images. Computer graphics is the difference between Steamboat Willie and Buzz Lightyear, between ping pong and PONG. It began in 1963 when an MIT graduate student named Ivan Sutherland created Sketchpad, the first true computer animation program. Sutherland noted: “Since motion can be put into Sketchpad drawings, it might be exciting to try making cartoons.” This book, the first full-length history of CG, shows us how Sutherland’s seemingly offhand idea grew into a multibillion dollar industry.
During World War II, the Allied military forces faced severe problems integrating equipment, tactics, and logistics into successful combat operations. To help confront these problems, scientists and engineers developed new means of studying which equipment designs would best meet the military’s requirements and how the military could best use the equipment it had on hand. By 1941 they had also begun to gather and analyze data from combat operations to improve military leaders’ ordinary planning activities.
In the 1960s, a team of Stanford musicians, engineers, computer scientists, and psychologists used computing in an entirely novel way: to produce and manipulate sound and create the sonic basis of new musical compositions. This group of interdisciplinary researchers at the nascent Center for Computer Research in Music and Acoustics (CCRMA, pronounced “karma”) helped to develop computer music as an academic field, invent the technologies that underlie it, and usher in the age of digital music.
The rise of the Indian information technology industry is a remarkable economic success story. Software and services exports from India amounted to less than $100 million in 1990, and today come close to $100 billion. But, as Dinesh Sharma explains in The Outsourcer, Indian IT’s success has a long prehistory; it did not begin with software support, or with American firms’ eager recruitment of cheap and plentiful programming labor, or with India’s economic liberalization of the 1990s.
