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.

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.

Subprime lending

In finance, subprime lending (also referred to as near-prime, non-prime, and second-chance lending) means making loans to people who may have difficulty maintaining the repayment schedule, sometimes reflecting setbacks, such as unemployment, divorce, medical emergencies, etc. Historically, subprime borrowers were defined as having FICO scores below 640, although "this has varied over time and circumstances."

These loans are characterized by higher interest rates, poor quality collateral, and less favorable terms in order to compensate for higher credit risk. Many subprime loans were packaged into mortgage-backed securities (MBS) and ultimately defaulted, contributing to the financial crisis of 2007–2008.

Proponents of subprime lending maintain that the practice extends credit to people who would otherwise not have access to the credit market. Professor Harvey S. Rosen of Princeton University explained, "The main thing that innovations in the mortgage market have done over the past 30 years is to let in the excluded: the young, the discriminated-against, the people without a lot of money in the bank to use for a down payment."

Prime95

Prime95 is the freeware application written by George Woltman that is used by GIMPS, a distributed computing project dedicated to finding new Mersenne prime numbers. More specifically, Prime95 refers to the Windows and Mac OS X versions of the software.

MPrime is the Linux command-line interface version of Prime95, to be run in a text terminal or in a terminal emulator window as a remote shell client. It is identical to Prime95 in functionality, except it lacks a graphical user interface.

Although most of the GIMPS software's source code is publicly available, it is technically not free software as users must abide by the project's distribution terms if the software is used to discover a prime number with at least 100,000,000 decimal digits and wins the $150,000 bounty offered by the EFF. As such, a user who uses Prime95 to discover a qualifying prime number would not be able to claim the prize directly ($50,000 will go to the person who finds the prime number). A free software package would not have this restriction.

Film (Polish magazine)

Film is a monthly Polish magazine devoted to cinema. It has been in publication since 1946, originally as a bimonthly publication. The founders were Jerzy Giżycki, Zbigniew Pitera, Tadeusz Kowalski, and Leon Bukowiecki.

Since September 2012, the editor-in-chief has been Tomasz Raczek. Previous editors have included Maciej Pawlicki, Lech Kurpiewski, Igor Zalewski and Robert Mazurek, Agnieszka Różycka, Marcin Prokop and Jacek Rakowiecki.

In January 2007, Film was purchased by Platforma Mediowa Point Group (PMPG).

Lubrication theory

In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer beneath the puck is much smaller than the dimensions of the puck itself.

Internal flows are those where the fluid is fully bounded. Internal flow lubrication theory has many industrial applications because of its role in the design of fluid bearings. Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant.

Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case the position of the free surface is itself unknown, and one goal of lubrication theory is then to determine this. Surface tension may then be significant, or even dominant. Issues of wetting and dewetting then arise. For very thin films (thickness less than one micrometre), additional intermolecular forces, such as Van der Waals forces or disjoining forces, may become significant.
