Spherical harmonics are often used to approximate the shape of the geoid.

Spherical harmonics are important in many theoretical and practical applications, particularly in the computation of atomic orbital electron configurations, representation of gravitational fields, geoids, and the magnetic fields of planetary bodies and stars, and characterization of the cosmic microwave background radiation.

Spherical stone shot were chosen because of cheapness ; forged iron, bronze and lead balls were tried, but the expense prevented their general adoption.

Spherical triangles were studied by early Greek mathematicians such as Menelaus of Alexandria, who wrote a book on spherical triangles called Sphaerica and developed Menelaus ' theorem.

The first Seidel aberration, Spherical Aberration, is independent of the position of the exit pupil ( as it is the same for axial and extra-axial pencils ).

Spherical mirror distortion is used in projection systems that utilize a digital video projector and a first surface convex spherical mirror to project images onto a dome.

which regular solutions for positive energies are given by so-called Bessel functions of the first kind ' so that the solutions written for R are the so-called Spherical Bessel function

Still Life with Spherical Mirror is a lithography print by the Dutch artist M. C. Escher which was first printed in November, 1934.

Hand with Reflecting Sphere also known as Self-Portrait in Spherical Mirror is a lithograph print by Dutch artist M. C. Escher, first printed in January 1935.

This sculpture first appears in Escher ’ s 1934 lithograph Still Life with Spherical Mirror.

Spherical buildings arise in two quite different ways in connection with the affine building X for SL < sub > n </ sub >( Q < sub > p </ sub >):

Spherical errors occur when errors have both uniform variance ( homoscedasticity ) and are uncorrelated with each other.

** M. C. Escher used special shapes of mirrors in order to achieve a much more complete view of his surroundings than by direct observation in Hand with Reflecting Sphere ( also known as Self-Portrait in Spherical Mirror ).

Spherical mechanisms are constructed by connecting links with hinged joints such that the axes of each hinge passes through the same point.

Spherical objects with this surface area have a radius or diameter in the range 89, 000 km to 564, 000 km.

Spherical geometry is not elliptic geometry but shares with that geometry the property that a line has no parallels through a given point.

Early in 1942, Wallis began experimenting with skipping marbles over water tanks in his garden, leading to his April 1942 paper " Spherical Bomb — Surface Torpedo ".

* Cradle – Spherical bowl turned on its side, typically connected with a bowl.

Along with her test she was required to take courses showing broader knowledge as well as prepare a thesis which was entitled Algebraic Groups of Spherical Trigonometry.

His publications include " Spherical Gravitational Waves " ( a collaboration with Peter Bergmann, former research assistant to Albert Einstein ), " Contributions to the Quantization Problem in General Relativity ", and " The Normal Modes Of A Hanging Oscillator Of Order N ".

Spherical trigonometry is a branch of spherical geometry which deals with polygons ( especially triangles ) on the sphere and the relationships between the sides and the angles.

Struycken is also an avid photographer with a website devoted to his Spherical Panoramas.

As an inventor, Sperling created, with Mike Simmons, the Astroscan telescope for Edmund Scientific, as well as " The Stars Above " star-finder for Spherical Concepts.

Spherical aberration occurs due to the increased refraction of light rays that occurs when rays strike a lens, or a reflection of light rays that occurs when rays strike a mirror near its edge in comparison with those that strike nearer the center.

Spherical astronomy is the branch of astronomy that is concerned with where celestial objects are located and how they move on the celestial sphere.
