When I started research in radio astronomy in 1947, the only known sources of cosmic radio waves were the Sun and the Milky Way. Observing techniques were simple: receivers were insensitive, there was no expectation that other radio sources could be located or even existed. A few years later, a whole vast radio sky was revealed, populated with supernova remnants, galaxies, and quasars.
Where will Uber stop? After the news that the Saudi’s have decided to invest $3.5bn in the company, came details of a further $2bn Uber wants to raise from financial markets using tecniques never deployed before by a start-up.
At a theoretical level, the concept of artificial intelligence has fueled and sharpened the philosophical debates on the nature of the mind, intelligence, and the uniqueness of human beings. Insights from the field have proved invaluable to biologists, psychologists, and linguists in helping to understand the processes of memory, learning, and language.
The so-called Suess effect in radiocarbon (14C) has been known for decades. Geological sources of carbon like coal and oil, that formed many millions of years ago, long since lost their radiocarbon through radioactive decay – they contain 14C-free “dead” carbon. From the mid-19th century the radiocarbon activity of the atmosphere declined as dead carbon from fossil fuels was dug out of the ground and burnt producing carbon dioxide (CO2) in the atmosphere.
The term ‘artificial intelligence’ was coined as long ago as 1956 to describe ‘the science and engineering of making intelligent machines’. The work that has happened in the subject since then has had enormous impact. Margaret Boden is Research Professor of Cognitive Science at the University of Sussex, and one of the best known figures in the field of Artificial Intelligence. We put four common questions to her about this exciting area of research.
Imagine a world where the majority of our workforce was composed of robots as capable and as psychologically similar to human beings. The robots are constantly working and are faster and more efficient than humans—leaving humans to be pushed towards early retirement to enjoy a life of leisure and wealth due to a large growth in investments on this artificial intelligence (AI).
Inforum, one of the largest librarian conferences in Eastern Europe, rolls into the Czech capital next week. Once again taking place at the University of Economics in Prague, Inforum 2016 promises to be a lively and thought-provoking look at some of the issues facing librarians in the Czech Republic and beyond.
The idea that the United States economy runs on information is so self-evident and commonly accepted today that it barely merits comment. There was an information revolution. America “stopped making stuff.” Computers changed everything. Everyone knows these things, because of an incessant stream of reinforcement from liberal intellectuals, corporate advertisers, and policymakers who take for granted that the US economy shifted toward an “knowledge-based” economy in the late twentieth century.
Pre-eminent among writers of mystery stories is, in my opinion, Dorothy L. Sayers. She is ingenious, witty, original – and scientific too, including themes like the fourth dimension, electroplating, and the acoustics of bells in some of her best stories. She is also the inventor of the voice-activated lock, which her hero Lord Wimsey deploys in the 1928 short story ‘The Adventurous Exploit of the Cave of Ali Baba’.
Our lives are full of distractions: overheard conversations, the neighbor’s lawnmower, a baby crying in the row behind us, pop-up ads on our computers. Much of the time we can mentally dismiss their presence. But what about when we are reading? I have been studying how people read with printed text versus on digital devices.
The words digital economy conjure images of young, tech-savvy entrepreneurs breaking moulds in a world where technology is disruptive. But could the reality be much more mundane and mercantile? When Facebook released “Facebook at work” earlier this year, the social networking goliath laid a huge challenge at the feat of LinkedIn, a powerful incumbent that had until then dominated its corner of the market.
The International Space Station was originally conceived as our base camp to the stars – the first step in a long journey of human civilisation exploring new planets, asteroids, and galaxies, and perhaps even helping us to meet other forms of life in the universe along the way. The International Space Station is an incredible feat in human engineering, politics, and bravery.
Noise barriers are not regarded with a great deal of affection. In fact, they’re not much regarded at all; perhaps not surprising, given that the goal of their installers is to ensure that those who benefit notice neither the barrier nor the noise sources it hides. The majority are basic workmanlike structures, built according to tried and trusted principles.
During the night, between 3rd and 4th September 1946, things were stirring in the basement of the internal medicine department, at the university hospital of Lund, Southern Sweden. A 47-year-old man had been admitted for treatment. His main problem was uraemia (urea in the blood), but he was also suffering from silicosis (a lung disorder), complicated by pneumonia.
There has been much recent talk about a possible robot apocalypse. One person who is highly skeptical about this possibility is philosopher John Searle. In a 2014 essay, he argues that “the prospect of superintelligent computers rising up and killing us, all by themselves, is not a real danger”.
How does one preserve the ephemera of the digital world? In a movement as large as the Arab Spring, with a huge digital imprint that chronicled everything from a government overthrow to the quiet boredom of waiting between events, archivists are faced with the question of how to preserve history. The Internet may seem to provide us with the curse of perfect recall, but the truth is it’s far from perfect — and perhaps there’s value in forgetting.
