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 ...

Light has always been described as an elegant partnership of electric and magnetic fields, yet for nearly two centuries physicists treated the magnetic side as a quiet background player. New ...

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 ...
