Spherical lenses are optical lenses with curved surfaces which converge or diverge light rays, thus forming a real or virtual image of an object. They are also known as singlets. Before selecting a ...

There are three types of cage design for spherical roller bearings: The distinct geometry of the inner and outer raceways facilitate the bearing's self-aligning properties. It is common for the inner ...

The trick is to get an Acty that's over 25 years old so you can register it in (some) US states. Oiwa Garage had two of the ...

[Nirav Patel] is a man on a mission. Since 2011 he has been obsessed with owning a spherical display, the kind of thing you see in museums and science centers, but on a desktop scale ...

It discusses applications of algebraic operations, Levi-Civita notation, and curvilinear coordinate systems like spherical polar and parabolic systems and structures, and analytical geometry of curves ...

Based on an experiment at CERN, a collaboration led by the Niels Bohr Institute, University of Copenhagen, can predict hitherto unchartered changes in the shape of nuclei.

On October 16 1843, the Irish mathematician William Rowan Hamilton had an epiphany during a walk alongside Dublin's Royal Canal.
