Solid geometry

In mathematics, solid geometry is the traditional name for the geometry of three-dimensional Euclidean space.

Stereometry deals with the measurements of volumes of various solid figures or Polyhedrons (three-dimensional figures) including pyramids, cylinders, cones, truncated cones, spheres, and prisms.

The Pythagoreans dealt with the regular solids, but the pyramid, prism, cone and cylinder were not studied until the Platonists. Eudoxus established their measurement, proving the pyramid and cone to have one-third the volume of a prism and cylinder on the same base and of the same height, and was probably the discoverer of a proof that the volume of a sphere is proportional to the cube of its radius.

Basic topics of solid geometry

Basic topics are:

SOLID (object-oriented design)

In computer programming, SOLID (Single responsibility, Open-closed, Liskov substitution, Interface segregation and Dependency inversion) is a mnemonic acronym introduced by Michael Feathers for the "first five principles" named by Robert C. Martin in the early 2000s that stands for five basic principles of object-oriented programming and design. The principles, when applied together, intend to make it more likely that a programmer will create a system that is easy to maintain and extend over time. The principles of SOLID are guidelines that can be applied while working on software to remove code smells by causing the programmer to refactor the software's source code until it is both legible and extensible. It is part of an overall strategy of agile and Adaptive Software Development.

Standard (1911 automobile)

The Standard was a German automobile manufactured between 1911 and 1912. The car was produced at Berlin-Charlottenburg using a rotary valve engine built by Henriod, which was unreliable and had not been fully developed; consequently, it was very unpopular.

Standard Superior

Standard Superior was an automobile, produced from 1933 to 1935 by Standard Fahrzeugfabrik of Ludwigsburg, Germany, founded by motorcycle maker Wilhelm Gutbrod and unrelated to the Standard Motor Company of England. These small cars were designed according to the patents by Josef Ganz and featured rear-mounted two-stroke engines.

After World War II, the same company made Gutbrod cars and introduced the model Gutbrod Superior.

History

In the first half of 1932, Wilhelm Gutbrod, the President of the Standard Fahrzeugfabrik, came into contact with German engineer Josef Ganz. Ganz had been working on a small car design since the early 1920s and had so far built two prototypes, one for Ardie in 1930 and one for Adler in 1931, called the Maikäfer (May Beetle). After a demonstration with the Maikäfer by Ganz, Gutbrod was most interested to build a small car according to this design. The Standard Fahrzeugfabrik then purchased a license from Ganz to develop and build a small car according to his design. The prototype of this new model, which was to be called Standard Superior, was finished in 1932. It featured a tubular chassis, a mid-mounted engine, and independent wheel suspension with swing-axles at the rear.

Standard (Italian automobile)

The Standard was an Italian automobile manufactured from 1906 until 1908 by the Fabbrica Automobili Standard of Torino. The company produced a 10/14 hp four-cylinder which was sometimes marketed under the name FAS.
