Over the last 60 years, ever-smaller generations of transistors have driven exponential growth in computing power. Could molecules, each turned into miniscule computer components, trigger even greater growth in computing over the next 60?
Atomic-scale computing, in which computer processes are carried out in a single molecule or using a surface atomic-scale circuit, holds vast promise [...]
In one of the many letters he wrote to his son in the 1740s, Lord Chesterfield offered the following advice: “There is time enough for everything in the course of the day, if you do but one thing at once, but there is not time enough in the year, if you will do two things [...]
Every year the Loebner Prize for artificial intelligence is awarded to the chatbot software able to converse most like a human. It is a version of the Turing test, proposed in 1950 by Alan Turing. A program passes when a human judge cannot tell that they are talking to a machine.
No machine has yet passed. [...]
Nanoelectronics researchers discover a bizarre shaped molecule in one of their devices can acts as first known quantum state-manipulable atom
Imagine a tiny arsenic atom embedded in a tiny strip of silicon atoms. An electric current is applied. Something strange arises on the surface — an exotic molecule. On one end is the spherical submerged arsenic [...]
Like a good gambler, Daphne Koller, a researcher at Stanford whose work has led to advances in artificial intelligence, sees the world as a web of probabilities. There is, however, nothing uncertain about her impact.
A mathematical theoretician, she has made contributions in areas like robotics and biology. Her biggest accomplishment — and at age 39, [...]
Are supercomputers on the verge of creating Matrix-style simulated realities? Michael McGuigan at Brookhaven National Laboratory in Upton, New York, thinks so. He says that virtual worlds realistic enough to be mistaken for the real thing are just a few years away.
In 1950, Alan Turing, the father of modern computer science, proposed the ultimate test [...]
It had to happen some time. Two researchers from Eötvös University in Budapest, Hungary, have developed a computer program that can play the video game Ms. Pac-Man better than an average human player. The New Scientist Tech reports that the AI program developed by András Lörincz and István Szita was allowed to develop it’s own [...]
