Quantum mechanics with single atoms and photons
Some 100 years after the birth of quantum mechanics, physicists are still learning more about the interactions between light and matter
Joseph Weber 1919 – 2000
In the late 1950s, Weber became intrigued by the relationship between gravitational theory and laboratory experiments. His book, General Relativity and Gravitational Radiation, was published in 1961, ...
Breaking through the quantum limit
Andrey Geim of the Universities of Nijmegen and Manchester, and co-workers from Russia, Belgium and the UK, measured the amount of flux entering micron-sized aluminium discs, where edge effects are im...

New life for Schrödinger’s cat
When the formalism of quantum mechanics is applied to experiments involving microscopic objects such as electrons, we often find that the resulting description assigns finite probability amplitudes to...
