This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

Holly has a degree in Medical Biochemistry from the University of Leicester. Her scientific interests include genomics, personalized medicine, and bioethics. A group of physicists was able to produce ...

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 ...

Optical rotation is a fundamental phenomenon observed when plane-polarised light traverses chiral media. This intrinsic property of chiral molecules renders them capable of rotating the plane of ...

In work that could aid predictions of unknown molecules' spectroscopic and other physical properties, researchers have measured optical rotation by an achiral organic compound. A prevalent ...

The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...

Scientists say they have found a more accurate way to measure time. We currently use atomic clocks to count the seconds, but tests on an alternative atomic timekeeper have revealed that it is more ...
