Prime number

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed as a product of primes that is unique up to ordering. The uniqueness in this theorem requires excluding 1 as a prime because one can include arbitrarily many instances of 1 in any factorization, e.g., 3, 1 · 3, 1 · 1 · 3, etc. are all valid factorizations of 3.

The property of being prime (or not) is called primality. A simple but slow method of verifying the primality of a given number n is known as trial division. It consists of testing whether n is a multiple of any integer between 2 and . Algorithms much more efficient than trial division have been devised to test the primality of large numbers. These include the Miller–Rabin primality test, which is fast but has a small probability of error, and the AKS primality test, which always produces the correct answer in polynomial time but is too slow to be practical. Particularly fast methods are available for numbers of special forms, such as Mersenne numbers. As of January 2016, the largest known prime number has 22,338,618 decimal digits.

Prime (liturgy)

Prime, or the First Hour, is a fixed time of prayer of the traditional Divine Office (Canonical Hours), said at the first hour of daylight (approximately 7:00 a.m.), between the morning Hour of Lauds and the 9 a.m. Hour of Terce. It is part of the Christian liturgies of Eastern Christianity, but in the Latin Rite it was suppressed by the liturgical reforms following the Second Vatican Council. However, clergy who have an obligation to celebrate the Liturgy of the Hours may still fulfil their obligation by using the Roman Breviary promulgated by Pope John XXIII in 1962, which contains the Hour of Prime. Like all the liturgical hours, except the Office of Readings, it consists primarily of Psalms. It is one of the Little Hours.

Name

The word "Prime" comes from Latin and refers to the first hour of daylight (i.e., dawn). Originally, in the West, Prime was called matitutina (hora), "morning hour". Later, in order to distinguish it from the nocturnal offices of Matins and Lauds, and to include it among hours of the day, it was called prima. The name is first met with in the Rule of St. Benedict. In the Antiphonary of Bangor it is called secunda.

Prime (film)

Prime is a 2005 American romantic comedy film starring Uma Thurman, Meryl Streep and Bryan Greenberg. It was written and directed by Ben Younger. The film grossed $67,937,503 worldwide.

Plot

Rafi (Uma Thurman) is a recently divorced, 37-year-old career woman from Manhattan who becomes romantically involved with David (Bryan Greenberg), a talented 23-year-old Jewish painter from the Upper West Side. Rafi shares all her secrets with her therapist Lisa (Meryl Streep) who, unbeknownst to Rafi, is David's mother. Lisa, supportive of Rafi's relationship with a younger man, discovers the connection and finds herself not only faced with the ethical and moral dilemma of counseling David's girlfriend, but also the reality that she feels differently about the relationship now that she knows her son is involved. Lisa consults her own therapist, and they decide that it is in the best interest of her patient Rafi for Lisa to continue treatment, as long as the relationship remains the "fling" it appears to be.

Medway (Mount Holly, South Carolina)

Medway or the Medway Plantation is a plantation in Mount Holly, South Carolina within Berkeley County, South Carolina. It is about 2 mi (3.2 km) east of U.S. Route 52 from the unincorporated community of Mount Holly, which is directly north of Goose Creek, South Carolina. It was named to the National Register of Historic Places on July 16, 1970.

History

Jan Van Arrsens, the Seigneur of Wernhaut (also "Weirnhoudt"), led a small group of settlers from Holland to the province of Carolina around 1686. He built his house on the Back River, which was formerly called the "Meadway" or "Medway" and is a tributary of the Cooper River. Van Arrsens died soon after his arrival and was buried at Medway.

His widow, Sabrina de Vignon, married Landgrave Thomas Smith around 1687, which made Smith one of the wealthiest men in the Province. Sabrina Smith died in 1689 and was buried at Medway. Thomas Smith was appointed governor of the Province of Carolina in 1693. He died in 1694 and was also buried at Medway.

Medway (1902)

The Medway was a four-masted barque built in 1902 by A. McMillan & Son, Dumbarton, Scotland. It was originally named the Ama Begonakoa when built for Messrs Sota and Aznar of Bilboa but was registered in Montevideo and first flew the Uruguayan flag.

The ship's figure-head was the Madonna and Child.

Devitt and Moore purchased the ship in June 1910 for £30,000 as a sail training ship for their company Devitt & Moore's Ocean Training Ships Limited. Devitt and Moore also used the ship in the Australian wool and wheat trade, and South American nitrate trade.

During one voyage, in December 1916, the Medway passed east to west around Cape Horn, which is possibly the last occasion that a square-rig sailing ship passed in that direction. Passing east to west around Cape Horn could take some square-riggers six weeks to beat around.

During 1918, the exigencies of the Great War necessitated the sale of Devitt and Moore's, then, only training ship, and it was sold to the Anglo-Saxon Petroleum Company (later Royal Dutch Shell ) for £41,000. The ship was then converted into a bulk oil carrier and renamed the Myr Shell and used for service in the Far East. Subsequently the Myr Shell became an oil depot ship in Singapore before being sold to Japanese shipbreakers for £1,500 in 1933.
