'Listening' to black holes form with gravity waves
New technology that breaks the quantum measurement barrier has been developed to detect the gravity waves first predicted by Einstein in 1916.
Uncertainty revisited: Novel tradeoffs in quantum measurement
Hubble finds birth certificate of oldest known star
(Phys.org) —A team of astronomers using NASA's Hubble Space Telescope has taken an important step closer to finding the birth certificate of a star that's been around for a very long time.
Getting around the 'uncertainty principle': Physicists make first direct measurements of polarization states of light
Researchers at the University of Rochester and the University of Ottawa have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both ...
Researchers racing to develop world's most accurate thermometer
The University of Queensland (UQ) physicists are on a quest to build the world's most accurate thermometer.
Mini robot builds NPL probe
Precision engineering requires accurate measurements and these are often made using co-ordinate measuring machines, or CMMs.
Scientists score one more victory over uncertainty in quantum physics measurements
(PhysOrg.com) -- Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider ...
CMS in 2011: A mountain of particle collision data
Datasets are the currency of physics. As data accumulate, measurement uncertainty ranges shrink, increasing the potential for discoveries and making non-observations more stringent, with more far-reaching ...
Are you certain, Mr. Heisenberg? New measurements deepen understanding of quantum uncertainty
Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often ...
'Old' information theory makes it easier to predict flooding
Many different aspects are involved in predicting high water and floods, such as the type of precipitation, wind, buildings and vegetation. The greater the number of variables included in predictive models, the better the ...
