Coordinates therefore do not provide enough information to describe the geometry of a spherical surface, or indeed the geometry of any more complicated space or spacetime.
32.
Glass flasks, stoppers, valves, funnels, and tubing are often connected together by ground glass joints, matching pairs of spherical surfaces that have been ground to a precise shape.
33.
Author of fundamental papers devoted to Optics, such as " Technical Optics ", " Non-spherical Surfaces in Optics ", " Technical Photometry ", " Optical Systems Composition ".

We actually see it from the Earth as moving in a line at various speeds over the spherical surface of the sky, because of our edge-on perspective to the circle.
35.
"' Spherical surface acoustic wave sensors "'use a type of Surface Acoustic Wave ( SAW ) that travels along the surface of a elasticity with exponentially decaying amplitude along depth.
36.
Additionally, if a spherical wavefront is refracted through a spherical lens, or reflected from a concave spherical surface, the refracted or reflected wavefront takes on the shape of a Cartesian oval.
37.
If the'spherical surface of last scattering'is expanding, the surface remains spherical and does not explain the isotropy or persistence of the CMBR-- Paul venter 07 : 37, 4 April 2006 ( UTC)
38.
The curvature information has been shown to reduce the error of a spherical surface by a factor of 1000 as compared to a surface described by the same number of planar triangles.
39.
Here,,, and are the angles at the center of the sphere subtended by the three arcs of the spherical surface triangle,, and, respectively .,, and are the surface angles opposite their respective arcs.

The arc shape occurs because of the spherical surface of the earth ( nick the peel of an orange with a knife and note the arc formed by the straight-edge of the knife ).
