Neutrinos Detected at Faster Than Light Speed
Source: CERN Posted: 9/23/11 The OPERA result is based on the observation of over 15000 neutrino events and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit.
Smarter robot arms
Source: MIT Posted: 9/22/11 A combination of two algorithms developed at MIT allows autonomous robots to execute tasks much more efficiently — and move more predictably.
Shake, rattle and … power up?
Source: MIT Posted: 9/18/11 Researchers at MIT have designed a device the size of a U.S. quarter that harvests energy from low-frequency vibrations, such as those that might be felt along a pipeline or bridge.
Quantum computing with light
Source: MIT Posted: 9/9/11 A switch that lets one photon alter the quantum state of another could point the way to both practical quantum computers and a quantum Internet.
'In a way science is a key to the gates of heaven, and the same key opens the gates of hell, and we do not have any instructions as to which is which gate.
Shall we throw away the key and never have a way to enter the gates of heaven? Or shall we struggle with the problem of which is the best way to use the key?'
