He also wrote many plays and documentaries for Pakistan television and Radio Pakistan.

Diving (association football): In association football, diving is an attempt by a player to gain an unfair advantage by falling to the ground and possibly feigning an injury, to give the impression that a foul has been committed.  Dives are often used to exaggerate the amount of contact present in a challenge.  Deciding on whether a player has dived is often very subjective, and one of the most controversial aspects of football discussion.  Players do this so they can receive free kicks or penalty kicks, which can provide scoring opportunities, or so the opposing player receives a yellow or red card, giving their own team an advantage.  Diving is also known as simulation (the term used by FIFA), and Schwalbe (German for swallow).

William Shakespeare: William Shakespeare ( ; 26 April 1564 (baptised) – 23 April 1616) was an English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist.  He is often called England's national poet, and the "Bard of Avon".  His extant works, including collaborations, consist of approximately 38 plays, 154 sonnets, two long narrative poems, and a few other verses, some of uncertain authorship.  His plays have been translated into every major living language and are performed more often than those of any other playwright.

Kumu Kahua Theatre: Kumu Kahua Theatre is a community theater located in the city of Honolulu on the island of Oahu in the state of Hawaii.  Kumu Kahua Theatre is best known for producing plays by local Hawaii-based playwrights, especially plays featuring themes and stories of the people of Hawaii.  (Their motto, as seen on their T-shirts and Web site, is "Plays about life in Hawaiʻ i. Plays by Hawaiʻ i's playwrights.  Plays for Hawaiʻ i's people.")  Therefore, actors are often featured utilizing their natural local dialect or respective ethnic accent, and many plays have incorporated or are solely written in Hawaiian Creole English, an English dialect commonly known in the Hawaiian islands as "pidgin".  Their productions are also known for involving local actors, designers, directors, and theater technicians.  Appropriately the Hawaiian language words "kumu kahua" translate to "original stage."  People familiar with the theatre often call it affectionately by its nickname of "Kumu".

Ion of Chios: Ion of Chios ( ; Greek: Ἴων ὁ Χῖος ; c. 490/480 – c. 420 BC) was a Greek writer, dramatist, lyric poet and philosopher.  He was a contemporary of Aeschylus, Euripides and Sophocles.  Of his many plays and poems only a few titles and fragments have survived.  He also wrote some prose works, including a Pythagorean text, the "Triagmos", of which a few fragments survive.

Morphology (archaeology): Morphology in archaeology, the study of shapes and forms, and their grouping into period styles remains a crucial tool, despite modern techniques like radiocarbon dating, in the identification and dating not only of works of art but all classes of archaeological artefact, including purely functional ones (ignoring the question of whether purely functional artefacts exist).  The term morphology ("study of shapes", from the Greek) is more often used for this.  Morphological analyses of many individual artefacts are used to construct typologies for different types of artefact, and by the technique of seriation a relative dating based on shape and style for a site or group of sites is achieved where scientific absolute dating techniques cannot be used, in particular where only stone, ceramic or metal artefacts or remains are available, which is often the case.  That artefacts such as pottery very often survive only in fragments makes precise knowledge of morphology even more necessary, as it is often necessary to identify and date a piece of pottery from only a few sherds.

Ali Nasr: Ali Nasr (1891-1961) was an Iranian dramatist and playwright and one of the founders of theatres in Iran.  He was born in Kashan.  When he was a young man, he went to Tehran and started to study the French language and literature.  Then he went to Europe and studied theater.  After coming back to Iran, he founded an intellectual group named “Iran comedy” in 1925.  Many prominent Iranian theatrical figures were part of this group and it became a very important factor in the development of modern Iranian drama.  Nasr wrote many plays, and also founded an acting school in Tehran in 1939, where many important dramatists and actors studied.

Foul papers: Foul papers are an author's working drafts.  The term is most often used in the study of the plays of Shakespeare and other dramatists of English Renaissance drama.  Once the composition of a play was finished, a transcript or "fair copy" of the foul papers was prepared, by the author or by a scribe.

Estadio Quisqueya: Quisqueya stadium Juan Marichal is a baseball stadium in Santo Domingo, Dominican Republic.  It is often used as a multi-use stadium.  Football club Atlético Pantoja used the venue for their inaugural Caribbean football championship match.  The Quisqueya holds about 14,469 people after its renovation.  The Dominican League Of Baseball Authority is in charge of its management.  It is the only stadium in Dominican Republic to host two different baseball teams, the Licey Tigers (Tigres del Licey) and the Escogido Lions (Leones del Escogido).  Its field dimensions are 335 feet at the foul poles, 383 feet at the power alleys, and 411 feet at the center field.  It was built in 1955 as Estadio Trujillo, during the Rafael Leonidas Trujillo Molina dictatorship, taking the Bobby Maduro Miami Stadium as the design base.

Chronosequence: A chronosequence (in forest sciences) is a set of forested sites that share similar attributes but are of different ages.  Since many processes in forest ecology take a long time (decades or centuries) to develop, chronosequence methods are used to represent and study the time-dependent development of a forest.  Field data from a chronosequence can be collected in a short period of several months.  For example, chronosequences are often used to study the changes in plant communities during succession.  A classic example of using chronosequences to study ecological succession is in the study of plant and microbial succession in recently deglactiated zones.  For example, a study from 2005 used the distance from the nose of a glacier as a proxy for site age.
