Die Meistersinger von Nürnberg, WWV 96, is a music drama in three acts, written and composed by Richard Wagner. It is among the longest operas commonly performed, usually taking around four and a half hours. It was first performed at the Königliches Hof- und National-Theater, today the home of the Bavarian State Opera, in Munich, on 21 June 1868. The conductor at the premiere was Hans von Bülow.
Tay–Sachs disease is a genetic disorder that results in the destruction of nerve cells in the brain and spinal cord. The most common type, known as infantile Tay–Sachs disease, becomes apparent around three to six months of age with the baby losing the ability to turn over, sit, or crawl. This is then followed by seizures, hearing loss, and inability to move. Death usually occurs in early childhood. Less commonly the disease may occur in later childhood or adulthood. These forms are generally milder in nature.
James Wolfe was a British Army officer known for his training reforms and remembered chiefly for his victory in 1759 over the French at the Battle of the Plains of Abraham in Quebec as a major general. The son of a distinguished general, Edward Wolfe, he received his first commission at a young age and saw extensive service in Europe where he fought during the War of the Austrian Succession. His service in Flanders and in Scotland, where he took part in the suppression of the Jacobite Rebellion, brought him to the attention of his superiors. The advancement of his career was halted by the Peace Treaty of 1748 and he spent much of the next eight years on garrison duty in the Scottish Highlands. Already a brigade major at the age of 18, he was a lieutenant-colonel by 23.
The Goldman Sachs Group, Inc., is an American multinational investment bank and financial services company headquartered in New York City. It offers services in investment management, securities, asset management, prime brokerage, and securities underwriting.
Jeffrey David Sachs is an American economist, academic, public policy analyst and former director of The Earth Institute at Columbia University, where he holds the title of University Professor. He is known as one of the world's leading experts on economic development and the fight against poverty.
The Sachs–Wolfe effect, named after Rainer K. Sachs and Arthur M. Wolfe, is a property of the cosmic microwave background radiation (CMB), in which photons from the CMB are gravitationally redshifted, causing the CMB spectrum to appear uneven. This effect is the predominant source of fluctuations in the CMB for angular scales above about ten degrees.
A blueshift is any decrease in wavelength, with a corresponding increase in frequency, of an electromagnetic wave; the opposite effect is referred to as redshift. In visible light, this shifts the color from the red end of the spectrum to the blue end.
Andreas Siegfried "Andrew" Sachs was a German-born British actor. He made his name on British television and rose to fame in the 1970s for his portrayals of the comical Spanish waiter Manuel in Fawlty Towers.
Robin David Sachs was an English actor, active in the theatre, television and films. He was also known for his voice-over work in films and video games.
Redshift-space distortions are an effect in observational cosmology where the spatial distribution of galaxies appears squashed and distorted when their positions are plotted as a function of their redshift rather than as a function of their distance. The effect is due to the peculiar velocities of the galaxies causing a Doppler shift in addition to the redshift caused by the cosmological expansion.
Arthur Michael "Art" Wolfe was an American astrophysicist, professor and the former Director of the Center for Astrophysics & Space Sciences at the University of California, San Diego. Together with Rainer K. Sachs, he authored the Sachs-Wolfe effect.
The Royal Saxon 23rd Reserve Division was a unit of the Imperial German Army in World War I. The division was formed on mobilization of the German Army in August 1914 as part of the XII Reserve Corps. The division was raised in the Kingdom of Saxony and was disbanded in 1919 during the demobilization of the German Army after World War I.
The CMB Cold Spot or WMAP Cold Spot is a region of the sky seen in microwaves that has been found to be unusually large and cold relative to the expected properties of the cosmic microwave background radiation (CMBR). The "Cold Spot" is approximately 70 µK colder than the average CMB temperature, whereas the root mean square of typical temperature variations is only 18 µK. At some points, the "cold spot" deviates 140 µK colder than the average CMB temperature.
Rainer Kurt "Ray" Sachs is a German-American computational radiation biologist and astronomer. He and Arthur M. Wolfe were the authors of the Sachs–Wolfe effect, which concerns a property of the Cosmic microwave background radiation. He and Ronald Kantowski were responsible for the Kantowski–Sachs dust solutions to the Einstein field equation. These are a widely used family of inhomogeneous cosmological models.
A wind instrument is a musical instrument that contains some type of resonator in which a column of air is set into vibration by the player blowing into a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece.
A musical instrument is an instrument created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for ritual, such as a trumpet to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications.
The Facebook Effect: The Inside Story of the Company That Is Connecting the World is a book by David Kirkpatrick and published by Simon & Schuster. It describes the history of Facebook and its social implications.
Domenico Marinucci is an Italian Full Professor of probability and mathematical statistics and astrophysicist at the University of Rome Tor Vergata. In 2006 he combined NRAO VLA Sky Survey radio galaxy and Wilkinson Microwave Anisotropy Probe cosmic microwave background and discovered that the Sachs–Wolfe effect happens later in space history.
