In the first round of testing, involving 60 measurements (six samples x five repeat tests x two rounds), an initial review of the results indicated that one sample consistently performed better than ...

Quantum measurement and uncertainty relations lie at the heart of quantum mechanics, delineating fundamental limits on the precision with which non-commuting observables can be simultaneously ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope revealed Jupiter’s moons and shook the geocentric universe. Thomas Young’s ...

(Nanowerk News) The equations that describe physical systems often assume that measurable features of the system — temperature or chemical potential, for example — can be known exactly. But the real ...

Scientific progress has been inseparable from better measurements. Before 1927, only human ingenuity seemed to limit how precisely we could measure things. Then Werner Heisenberg discovered that ...

Quantum particles are not really just particles…they are also waves. The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there's something out there in ...

Breaking up: a new measurement of the hydrogen dissociation energy disagrees with theory. (Courtesy: iStock/FrankRamspott) The most precise experimental value for the dissociation energy of molecular ...
