[Colin] and [Fergus] have been working with GPS for years now, and like most builders of really cool things, they’re often limited by the precision of off-the-shelf GPS units. While a GPS receiver is ...

Although today's best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from the spin statistics of the many atoms they interrogate, known ...

Photographers looking for a compact levelling system to make sure their camera is always precisely horizontal, may be interested in a new piece of kit which has been created by a team of developers ...

Ultraviolet spectroscopy plays a critical role in the study of electronic transitions in atoms and rovibronic transitions in molecules. These studies are essential for tests of fundamental physics, ...

The ability to produce quality products hinges on four key competencies: modeling of process form and precision levels, design tolerancing of parts and products, selecting production processes that ...
