Alan Mathison Turing (1912-1954) was a mathematician and computer scientist, remembered for his revolutionary Automatic Computing Engine, on which the first personal computer was based, and his crucial role in breaking the ENIGMA code during the Second World War. He continues to be regarded as one of the greatest scientists of the 20th century.
The construction or recertification of a nuclear power plant often draws considerable attention from activists concerned about safety. However, nuclear powered US Navy (USN) ships routinely dock in the most heavily populated areas without creating any controversy at all. How has the USN managed to maintain such an impressive safety record? The USN is not alone, many organizations, such as nuclear public utilities, confront the need to maintain perfect reliability or face catastrophe.
Are you worried about catching the flu, or perhaps even Ebola? Just how worried should you be? Well, that depends on how fast a disease will spread over social and transportation networks, so it’s obviously important to obtain good estimates of the speed of disease transmission and to figure out good containment strategies to combat disease spread.
Checking the website for the upcoming Audio Engineering Society (AES) convention in Los Angeles, I took note of the swipes promoting the event. Each heading was framed as follows: If it’s about ____________ it’s at AES. The slide show contained nine headings that are to be a part of the upcoming convention (in no particular order because you start at whatever point in the slide show you happened to log-in to the site).
Today, 60 years ago, the visionary convention establishing the European Organization for Nuclear Research — better known with its French acronym, CERN — entered into force, marking the beginning of an extraordinary scientific adventure that has profoundly changed science, technology, and society, and that is still far from over.
2014 marks not just the centenary of the start of World War I, and the 75th anniversary of World War II, but on 29 September it is 60 years since the establishment of CERN, the European Centre for Nuclear Research or, in its modern form, Particle Physics.
Apps are all the rage nowadays, including apps to help fight rage. That’s right, the iTunes app store contains several dozen apps designed to manage anger or reduce stress. Smartphones have become such a prevalent component of everyday life, it’s no surprise that a demand has risen for phone programs (also known as apps) that help us manage some of life’s most important elements, including personal health.
Have you ever thought that your body movements can be transformed into learning stimuli and help to deal with abstract concepts? Subjects in natural science contain plenty of abstract concepts which are difficult to understand through reading-based materials, in particular for younger learners who are at the stage of developing their cognitive ability.
World Water Monitoring Day is an annual celebration reaching out to the global community to build awareness and increase involvement in the protection of water resources around the world. The hope is that individuals will feel motivated and empowered to investigate basic water monitoring in their local area.
Innovation is a primary driver of economic growth and of the rise in living standards, and a substantial body of research has been devoted to documenting the welfare benefits from it (an example being Trajtenberg’s 1989 study). Few areas have experienced more rapid innovation than the Personal Computers (PC) industry, with much of this progress being associated with a particular component, the Central Processing Unit (CPU). The past few decades had seen a consistent process of CPU innovation, in line with Moore’s Law.
From mechanical turks to science fiction novels, our mobile phones to The Terminator, we’ve long been fascinated by machine intelligence and its potential — both good and bad. We spoke to philosopher Nick Bostrom, author of Superintelligence: Paths, Dangers, Strategies, about a number of pressing questions surrounding artificial intelligence and its potential impact on society.
It was the nest-building season, but after days of long hard work, the sparrows sat in the evening glow, relaxing and chirping away.
Facebook celebrated its tenth anniversary in February. It has over 1.2 billion active users — equating to one user for every seven people worldwide. This social networking phenomenon has not only given our society a new way of sharing information with others; it’s changed the way we think about “liking” and “friending.”
A large variety of complex systems in ecology, climate science, biomedicine, and engineering have been observed to exhibit so-called tipping points, where the dynamical state of the system abruptly changes. Typical examples are the rapid transition in lakes from clear to turbid conditions or the sudden extinction of species after a slightly change of environmental conditions. Data and models suggest that detectable warning signs may precede some, though clearly not all, of these drastic events. This view is also corroborated by recently developed abstract mathematical theory for systems, where processes evolve at different rates and are subject to internal and/or external stochastic perturbations.
This week—August 15, to be exact—celebrates the climax of Air Conditioning Appreciation Days, a month-long tribute to the wonderful technology that has made summer heat a little more bearable for millions of people.
As soon as humanity began its quest for knowledge, people have also attempted to organize that knowledge. From the invention of writing to the abacus, from medieval manuscripts to modern paperbacks, from microfiche to the Internet, our attempt to understand the world — and catalog it in an orderly fashion with dictionaries, encyclopedias, libraries, and databases — has evolved with new technologies.
