Physicists in Italy have demonstrated that empty space can cause light to rotate in the presence of a large magnetic field. Although the effect seen by Emilio Zavattini and co-workers on the PVLAS ...

Basic polarimeters are comprised of a light source, two polarizing filters, an eyepiece for direct observation of optical rotation and a sample tube containing a solvent of interest. This phenomenon ...

AN interesting confirmation of Voigt's theory of absorption has been afforded by an experiment by Prof. Zeeman, described in the Proceedings of the Amsterdam Academy of Sciences of June 25. In Voigt's ...

A team of researchers led by Philip Walther at the University of Vienna carried out a pioneering experiment where they measured the effect of the rotation of Earth on quantum entangled photons. The ...
