  • The years 1945–55 saw the emergence of a radically new kind of device: the high-speed stored-program digital computer. Secret wartime projects in areas such as code-breaking, radar and ballistics had produced a wealth of ideas and technologies that kick-started this first decade of the Information Age. The brilliant mathematician and code-breaker Alan Turing was just one of several British pioneers whose prototype machines led the way. Turning theory into practice proved tricky, but by 1948 five UK research groups had begun to build practical stored-program computers.

  • In the not too distant past, MSOS (multiple system operators) relied on the customer to monitor network outages, a system that greatly contributed to cable television's reputation for inconsistent service.

  • Until relatively recent times, most periods of technological development have been linked to changes in the use of materials (eg the stone, bronze and iron ages). In more recent years the driving force for technological change in many respects has shifted towards information technology. This is amply illustrated by the way the humble microprocessor has built intelligence into everyday domestic appliances.

In automobiles the same computers are used to make smart cars by controlling the steering, brakes, exhaust system, suspension, seats, anti-theft systems, sound-entertainment systems, shifting, doors, repair analysis, navigation, noise suppression, environment, comfort, etc. On some systems engine speed is adjusted at the instant when the transmission shifts gears, resulting in a smoother shifting process.

  • Experimental mathematics, a child of our ‘Computer Age’, allows us glimpses into the world of numbers that are breathtaking, not just to mathematicians. Abstract concepts, until recently known only to specialists - for example Feigenbaum diagrams or Julia sets - are becoming vivid objects, which even renew the motivation of students. Beauty and mathematics: they belong together visibly, and not just in the eyes of mathematicians

  • This golden age of the industrial workers in the United States is partly mythological, but it had roots in reality (Webber and Rigby, 1996). Rising living standards, predictable employment at a family wage, and homeownership were no myth for millions of workers. Its effects even spilled onto members of minority groups, particularly African Americans, who continued to be socially marginalized, but who migrated from rural areas to cities and found work in factories.

  • I hate the fact that fans who want to do what readers have always done are expected to play in the same system as all these hotshot agents and lawyers. It's just stupid to say that an elementary school classroom should have to talk to a lawyer at a giant global publisher before they put on a play based on one of my books. It's ridiculous to say that people who want to “loan” their electronic copy of my book to a friend need to get a license to do so. Loaning books has been around longer than any publisher on Earth, and it's a...

  • There too, the accounts of feminist film culture produced in the mid-to-late 70s tended to emphasize a dichotomy between two concerns of the women's movement and two types of film work that seemed to be at odds with each other: one called for immediate documentation for purposes of political activism, consciousness- raising, self-expression or the search for "positive images" of woman; the other insisted on rigorous, formal work on the medium - or bet-...

  • The microsimulation approach combined with reweighting contrasts with a popular method of examining population ageing, which combines population projections with age-specific per capita expenditures on a range of benefits in order to obtain projected social expenditures. These are typically combined with GDP projections based on age-specific labour force participation and unemployment ratios, along with productivity growth assumptions.

  • The subjects then used an online system to perform the experimental task. A copy of the text specification with the example diagram was placed in front of the computer for easy reference, and the UML experimental diagrams were presented in random order for each subject. The subjects gave a yes/no response to each presented diagram, indicating whether they thought the diagram matched the specification or not: two keys on the keyboard were used for this input. 16 practice diagrams (randomly selected from the 21 experimental diagrams) were presented first.
