Coin

A coin is a piece of hard material used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government.

Coins are usually metal or alloy, or sometimes made of synthetic materials. They are usually disc shaped. Coins made of valuable metal are stored in large quantities as bullion coins. Other coins are used as money in everyday transactions, circulating alongside banknotes. Usually the highest value coin in circulation (i.e. excluding bullion coins) is worth less than the lowest-value note. In the last hundred years, the face value of circulation coins has occasionally been lower than the value of the metal they contain, for example due to inflation. If the difference becomes significant, the issuing authority may decide to withdraw these coins from circulation, or the public may decide to melt the coins down or hoard them (see Gresham's law).

Exceptions to the rule of face value being higher than content value also occur for some bullion coins made of silver or gold (and, rarely, other metals, such as platinum or palladium), intended for collectors or investors in precious metals. Examples of modern gold collector/investor coins include the British sovereign minted by the United Kingdom, the American Gold Eagle minted by the United States, the Canadian Gold Maple Leaf minted by Canada, and the Krugerrand, minted by South Africa. While the Eagle, Maple Leaf, and Sovereign coins have nominal (purely symbolic) face values; the Krugerrand does not.

Two pounds (British coin)

The British two pound (£2) coin is a denomination of the pound sterling. Its obverse has featured the profile of Queen Elizabeth II since the coin’s introduction. Two different portraits of the Queen have been used, with the latest design by Jody Clark being introduced in 2015. The reverse features an abstract design symbolising the history of technological achievement. A new reverse design featuring Britannia began to enter circulation during 2015.

The coin was introduced on 15 June 1998 (coins minted 1997) after a review of the United Kingdom's coinage decided that a general-circulation £2 coin was needed. The new bi-metallic design replaced a series of commemorative, uni-metallic coins which were issued between 1986 and 1996 to celebrate special occasions. Although legal tender, these coins have never been common in everyday circulation.

As of March 2014 there were an estimated 417 million £2 coins in circulation with an estimated face value of £831.756 million.

Private (rocket)

Private was an experimental rocket developed by the California Institute of Technology on behalf of the United States Army. Tested in two different configurations, it provided the proof of concept that a fin-stabilised ballistic missile was technologically feasible, and led to the development of the Corporal ballistic missile.

History

The Private program was begun in 1944 as an outgrowth of work by the California Institute of Technology's Guggenheim Aeronautical Laboratory that had produced the first practical jet-assisted take-off (JATO) rockets. A proposal to adapt the JATO rockets for research into the development of ballistic missiles was accepted, and the first flight of the Private A rocket, developed under the direction of Tsien Hsue-shen, took place in December 1944, conducted at Camp Irwin in California.

Private A was an unguided, fin-stabilised ballistic rocket; it consisted of a JATO unit equipped with cruciform tail fins, and a set of four T22 booster rockets that were jettisoned after launch. This made Private A the first multistage rocket to be flown in the United States.

Information hiding

In computer science, information hiding is the principle of segregation of the design decisions in a computer program that are most likely to change, thus protecting other parts of the program from extensive modification if the design decision is changed. The protection involves providing a stable interface which protects the remainder of the program from the implementation (the details that are most likely to change).

Written another way, information hiding is the ability to prevent certain aspects of a class or software component from being accessible to its clients, using either programming language features (like private variables) or an explicit exporting policy.

Overview

The term encapsulation is often used interchangeably with information hiding. Not all agree on the distinctions between the two though; one may think of information hiding as being the principle and encapsulation being the technique. A software module hides information by encapsulating the information into a module or other construct which presents an interface.
