John William Strutt, 3rd Baron Rayleigh English physicist

John William Strutt, 3rd Baron Rayleigh,, was a British scientist who made extensive contributions to both theoretical and experimental physics. He spent all of his academic career at the University of Cambridge. Among many honours, he received the 1904 Nobel Prize in Physics "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies." He served as President of the Royal Society from 1905 to 1908 and as Chancellor of the University of Cambridge from 1908 to 1919.

The New York Renaissance, also known as the Renaissance Big Five and as the Rens, was an all-black professional basketball team established February 13, 1923, by Robert "Bob" Douglas in agreement with the Renaissance Casino and Ballroom. The Casino and Ballroom at 138th Street and Seventh Avenue in Harlem was an entertainment complex including a ballroom that served as the Big Five's home court. Following each game, a dance took place. The success of the Rens shifted the focus of black basketball from amateur teams to professional teams. Initially, the Rens played mostly in Harlem, but by the end of the 1920s, as attendance began to dwindle, the team could be found more often playing on the road, barnstorming across the country out of necessity. The Renaissance are also the topic of the 2011 documentary On the Shoulders of Giants.

Acoustic impedance and specific acoustic impedance are measures of the opposition that a system presents to the acoustic flow resulting from an acoustic pressure applied to the system. The SI unit of acoustic impedance is the pascal second per cubic metre or the rayl per square metre, while that of specific acoustic impedance is the pascal second per metre or the rayl. In this article the symbol rayl denotes the MKS rayl. There is a close analogy with electrical impedance, which measures the opposition that a system presents to the electrical flow resulting from an electrical voltage applied to the system.

David "Dave" Seville is a fictional character, the producer and manager of the fictional singing group Alvin and the Chipmunks. The character was created by Ross Bagdasarian Sr. Bagdasarian had used the name "David Seville" as his stage name prior to the creation of the Chipmunks, while writing and recording novelty records in the 1950s. One of the records, recorded under the David Seville stage name, was "Witch Doctor", featuring a sped-up high-pitched vocal technique that Bagdasarian would later use in "The Chipmunk Song ", which would introduce both Alvin and the Chipmunks as a singing group and Bagdasarian's music producer "Dave". Bagdasarian would go on to create The Alvin Show, based on the Alvin and the Chipmunks group, where he voiced the semi-fictional character David Seville, based largely on himself, with Alvin based on Ross's sometimes rebellious son Adam.

Victoria (crater) crater on Mars

Victoria is an impact crater on Mars located at 2.05°S, 5.50°W in the Meridiani Planum extraterrestrial plain, lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This crater was first visited by the Mars Exploration Rover Opportunity. It is roughly 730 metres wide, nearly eight times the size of the crater Endurance, visited by Opportunity from sols 951 to 1630. It is informally named after Victoria – one of the five Spanish ships of Ferdinand Magellan and the first ship to circumnavigate the globe – and formally named after Victoria, Seychelles. Along the edges of the crater are many outcrops within recessed alcoves and promontories, named for bays and capes that Magellan discovered.
