The largest opera houses of Paris are the 19th-century Opéra Garnier (historical Paris Opéra) and modern Opéra Bastille; the former tends toward the more classic ballets and operas, and the latter provides a mixed repertoire of classic and modern. In middle of the 19th century, there were three other active and competing opera houses: the Opéra-Comique (which still exists), Théâtre-Italien, and Théâtre Lyrique (which in modern times changed its profile and name to Théâtre de la Ville). Philharmonie de Paris, the modern symphonic concert hall of Paris, opened in January 2015. Another musical landmark is the Théâtre des Champs-Élysées, where the first performances of Diaghilev's Ballets Russes took place in 1913.

At the 2004 Summer Olympics, Bermuda competed in sailing, athletics, swimming, diving, triathlon and equestrian events. In those Olympics, Bermuda's Katura Horton-Perinchief made history by becoming the first black female diver to compete in the Olympic Games. Bermuda has had one Olympic medallist, Clarence Hill, who won a bronze medal in boxing. Bermuda also competed in Men's Skeleton at the 2006 Winter Olympics in Turin, Italy. Patrick Singleton placed 19th, with a final time of 1:59.81. Jillian Teceira competed in the Beijing Olympics in 2008. It is tradition for Bermuda to march in the Opening Ceremony in Bermuda shorts, regardless of the summer or winter Olympic celebration. Bermuda also competes in the biennial Island Games, which it hosted in 2013.
What is the Olympic tradition for Bermuda, regardless of season?
march in the Opening Ceremony in Bermuda shorts

In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three phase load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (var). The purpose is to counteract inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. Individual motor or lamp loads may have capacitors for power factor correction, or larger sets of capacitors (usually with automatic switching devices) may be installed at a load center within a building or in a large utility substation.
How are capacitors used for for power factor correction prepared?
as three capacitors connected as a three phase load
