It was a very interesting week for physics as experiments at the LHC showed that a particle known as the "beauty quark" behaved as has been predicted by the Standard Model and thus represented a new blow for the "supersymmetry" ...
Instruments that measure the properties of light, known as spectrometers, are widely used in physical, chemical, and biological research. These devices are usually too large to be portable, but MIT scientists have now shown ...
