Some 100 years after the birth of quantum mechanics, physicists are still learning more about the interactions between light and matter
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, ...
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...

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...
In his original thought experiment, Schrodinger imagined that a cat is locked in a box, along with a radioactive atom that is connected to a vial containing a deadly poison. If the atom decays, it cau...
In a Bose-Einstein condensate a gas of atoms is cooled until the de Broglie wavelength of the atoms exceeds the inter-atom spacing. If the atoms are bosons – that is, if they have a “spin&...
Manfred Bayer of the University of Wurzburg in Germany, and co-workers in Wurzburg and the National Research Council of Canada in Ottawa, studied indium gallium arsenide quantum dots grown on a galliu...
There is no doubt that quantum theory has been remarkably successful and has passed every experimental test it has been subject to. But the interpretation of quantum theory – in particular the m...
Hendrik Brugt Gerhard Casimir was born in the Hague in the Netherlands in 1909 and received his PhD from the University of Leiden in 1931. After working with Bohr in Copenhagen and Pauli in Zurich, he...
Sam Treiman was a distinguished particle theorist. The famous Goldberger-Treiman relation was, at the time of its discovery in 1958, an amazing connection between the strong and weak interactions. Col...
