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.

Solid (song)

"Solid" is a hit single recorded by the husband-and-wife songwriting duo Ashford & Simpson. It was featured on the 1984 album Solid, and released as a single in November of that year.

It was written by the two and follows a similar template of most of their hits for other artists, except with a slight 1980s inflection to the music. In the lyrics, the narrators of the song celebrate the fact that, through all the difficulties and problems their relationship has faced, they made their love stronger by learning how to forgive and trust each other, and their love for one another remains "solid as a rock".

It was their biggest hit as performers, topping the U.S. R&B chart, peaking at number 12 on the Billboard Hot 100, and peaking at number three on the UK Singles Chart in 1985. It was the 16th best-selling single of 1985 in the UK.

In 2009, Ashford & Simpson remade the song in honor of President Barack Obama, calling it "Solid (As Barack)".

Music video

The video is set on a rainy afternoon in a park. Valerie Simpson exits a taxi in a park on a cloudy day, and escapes from a sudden downpour underneath a bridge. As she sings the opening of the song a cappella, she's joined by Nick Ashford, who joins in. As the video progresses, they're joined by others, including a cyclist in yellow spandex, a gang who just want to sing, and several bongo players, also trying to escape the downpour.

Station (New Zealand agriculture)

A station, in the context of New Zealand agriculture, is a large farm dedicated to the grazing of sheep and cattle. The use of the word for the farm or farm buildings date back to the mid-nineteenth century. The owner of a station is called a runholder.

Some of the stations in the South Island have been subject to the voluntary tenure review process. As part of this process the government has been buying out all or part of the leases. Poplars Station in the Lewis Pass area was purchased in part by the government in 2003. The Nature Heritage Fund was used to purchase 4000 ha for $1.89 million. Birchwood Station was bought in 2005 to form part of the Ahuriri Conservation ParkSt James Station was purchased by the Government in 2008.

Notable stations

Station (roller coaster)

The station of a roller coaster is the area where lines to rides divide into lanes to board the roller coaster.

The station is also an area for riders to exit. Often, on high impact coasters, guests will be able to place personal items in a safe location in stations to ensure items would not get damaged or destroyed on the roller coaster. After the ride, guests claim items.
