Tarì
A tarì (طري lit. "fresh" or "newly minted money" in Arabic) was the Christian designation of a type of gold coin of Islamic origin minted in Sicily, Malta and Southern Italy from about 913 to 1859.
History
In the Islamic world, this type of coin was designated under the name ruba'i, or quarter-dinar, as it weighed 1.05g of gold. The ruba'i had been minted by the Muslims in Sicily, unlike the Muslim rulers of North Africa, who preferred the larger dinar. It became highly popular as it was smaller and therefore more convenient than the large-sized 4.25g dinar.
The tarì were so widespread that imitations were made in southern Italy (Amalfi and Salerno) from the mid-tenth century, which only used illegible "pseudo-Kufic" imitations of Arabic. When the Normans invaded Sicily in the 12th century, they issued tarì coins bearing legends in Arabic and Latin.Roger II of Sicily issued such coins, becoming the only Western ruler at that time to mint gold coins. Their title was 161⁄3 carat, with some adjunction of silver and copper. The tarì were also produced by the Hohenstaufens and the early Angevins.
The Color of Time
The Color of Time (aka Tar) is a 2012 drama film written and directed by twelve New York University film students: Edna Luise Biesold, Sarah-Violet Bliss, Gabrielle Demeestere, Alexis Gambis, Shruti Ganguly, Brooke Goldfinch, Shripriya Mahesh, Pamela Romanowsky, Bruce Thierry Cheung, Tine Thomasen, Virginia Urreiztieta and Omar Zúñiga Hidalgo. It stars James Franco, Henry Hopper, Mila Kunis, Jessica Chastain and Zach Braff. It premiered on November 16, 2012 at the Rome Film Festival. It was released in the United Kingdom in 2014 under the new title Forever Love. The film was released in the United States in theaters and on demand beginning on December 12, 2014.
Plot
The different parts of Pulitzer Prize winner C.K. Williams' life told through his poems. Flashbacks of his childhood, his teens, college years, to when he meets and marries his wife, Catherine (Kunis) and the birth of his children and parenthood. The film is narrated by different versions of Williams (Franco, Hopper, March, Unger), depicting the different aspects of Williams through the years.

Anomaly (physics)
In quantum physics an anomaly or quantum anomaly is the failure of a symmetry of a theory's classical action to be a symmetry of any regularization of the full quantum theory. In classical physics an anomaly is the failure of a symmetry to be restored in the limit in which the symmetry-breaking parameter goes to zero. Perhaps the first known anomaly was the dissipative anomaly in turbulence: time-reversibility remains broken (and energy dissipation rate finite) at the limit of vanishing viscosity.
Technically, an anomalous symmetry in a quantum theory is a symmetry of the action, but not of the measure, and so not of the partition function as a whole.
Global anomalies
A global anomaly is anomaly associated with global symmetry.
Scaling and renormalization
The most prevalent global anomaly in physics is associated with the violation of scale invariance by quantum corrections, quantified in renormalization. Since regulators generally introduce a distance scale, the classically scale-invariant theories are subject to renormalization group flow, i.e., changing behavior with energy scale. For example, the large strength of the strong nuclear force results from a theory that is weakly coupled at short distances flowing to a strongly coupled theory at long distances, due to this scale anomaly.
