Polish composers of the following generation included virtuosi such as Moritz Moszkowski, but, in the opinion of J. Barrie Jones, his "one worthy successor" among his compatriots was Karol Szymanowski (1882–1937). Edvard Grieg, Antonín Dvořák, Isaac Albéniz, Pyotr Ilyich Tchaikovsky and Sergei Rachmaninoff, among others, are regarded by critics as having been influenced by Chopin's use of national modes and idioms. Alexander Scriabin was devoted to the music of Chopin, and his early published works include nineteen mazurkas, as well as numerous études and preludes; his teacher Nikolai Zverev drilled him in Chopin's works to improve his virtuosity as a performer. In the 20th century, composers who paid homage to (or in some cases parodied) the music of Chopin included George Crumb, Bohuslav Martinů, Darius Milhaud, Igor Stravinsky and Heitor Villa-Lobos.

Persistent heavy rain and landslides in Wenchuan County and the nearby area badly affected rescue efforts. At the start of rescue operations on May 12, 20 helicopters were deployed for the delivery of food, water, and emergency aid, and also the evacuation of the injured and reconnaissance of quake-stricken areas. By 17:37 CST on May 13, a total of over 15,600 troops and militia reservists from the Chengdu Military Region had joined the rescue force in the heavily affected areas. A commander reported from Yingxiu Town, Wenchuan, that around 3,000 survivors were found, while the status of the other inhabitants (around 9,000) remained unclear. The 1,300 rescuers reached the epicenter, and 300 pioneer troops reached the seat of Wenchuan at about 23:30 CST. By 12:17 CST, May 14, 2008, communication in the seat of Wenchuan was partly revived. On the afternoon of May 14, 15 Special Operations Troops, along with relief supplies and communications gear, parachuted into inaccessible Mao County, northeast of Wenchuan.

Even though, both Kashmir Shaivism and Advaita Vedanta are non-dual philosophies which give primacy to Universal Consciousness (Chit or Brahman), in Kashmir Shavisim, as opposed to Advaita, all things are a manifestation of this Consciousness. This implies that from the point of view of Kashmir Shavisim, the phenomenal world (Śakti) is real, and it exists and has its being in Consciousness (Chit). Whereas, Advaita holds that Brahman is inactive (niṣkriya) and the phenomenal world is an illusion (māyā). The objective of human life, according to Kashmir Shaivism, is to merge in Shiva or Universal Consciousness, or to realize one's already existing identity with Shiva, by means of wisdom, yoga and grace.

Question: Which group sees the world as illusion?
Answer: Advaita.

The origin of the domestic dog (Canis lupus familiaris or Canis familiaris) is not clear. Whole genome sequencing indicates that the dog, the gray wolf and the extinct Taymyr wolf diverged at around the same time 27,000–40,000 years ago. These dates imply that the earliest dogs arose in the time of human hunter-gatherers and not agriculturists. Modern dogs are more closely related to ancient wolf fossils that have been found in Europe than they are to modern gray wolves. Nearly all dog breeds' genetic closeness to the gray wolf are due to admixture, except several Arctic dog breeds are close to the Taimyr wolf of North Asia due to admixture.

---

Question: Most breeds share a genetic likeness to what animal?
Answer: gray wolf.

Logical empiricism (also logical positivism or neopositivism) was an early 20th-century attempt to synthesize the essential ideas of British empiricism (e.g. a strong emphasis on sensory experience as the basis for knowledge) with certain insights from mathematical logic that had been developed by Gottlob Frege and Ludwig Wittgenstein. Some of the key figures in this movement were Otto Neurath, Moritz Schlick and the rest of the Vienna Circle, along with A.J. Ayer, Rudolf Carnap and Hans Reichenbach.

While the decision (with four dissents) ultimately upheld the state law allowing the funding of transportation of students to religious schools, the majority opinion (by Justice Hugo Black) and the dissenting opinions (by Justice Wiley Blount Rutledge and Justice Robert H. Jackson) each explicitly stated that the Constitution has erected a "wall between church and state" or a "separation of Church from State": their disagreement was limited to whether this case of state funding of transportation to religious schools breached that wall. Rutledge, on behalf of the four dissenting justices, took the position that the majority had indeed permitted a violation of the wall of separation in this case: "Neither so high nor so impregnable today as yesterday is the wall raised between church and state by Virginia's great statute of religious freedom and the First Amendment, now made applicable to all the states by the Fourteenth." Writing separately, Justice Jackson argued that "[T]here are no good grounds upon which to support the present legislation. In fact, the undertones of the opinion, advocating complete and uncompromising separation of Church from State, seem utterly discordant with its conclusion yielding support to their commingling in educational matters."

Question: What was the disagreement between the Justices over whether funding breached what?
Answer: that wall.

A number of events in 2006 pushed renewable energy up the political agenda, including the US mid-term elections in November, which confirmed clean energy as a mainstream issue. Also in 2006, the Stern Review made a strong economic case for investing in low carbon technologies now, and argued that economic growth need not be incompatible with cutting energy consumption. According to a trend analysis from the United Nations Environment Programme, climate change concerns coupled with recent high oil prices and increasing government support are driving increasing rates of investment in the renewable energy and energy efficiency industries.

The Arians no longer presented an unbroken front to their orthodox opponents. The Emperor Constantius, who had been the cause of so much trouble, died 4 November, 361 and was succeeded by Julian. The proclamation of the new prince's accession was the signal for a pagan outbreak against the still dominant Arian faction in Alexandria. George, the usurping Bishop, was flung into prison and murdered. An obscure presbyter of the name of Pistus was immediately chosen by the Arians to succeed him, when fresh news arrived that filled the orthodox party with hope. An edict had been put forth by Julian permitting the exiled bishops of the "Galileans" to return to their "towns and provinces". Athanasius received a summons from his own flock, and he accordingly re-entered his episcopal capitol on 22 February, 362.

Since the 1970s, an important focus of study has been the ozone layer in the atmosphere above Antarctica. In 1985, three British scientists working on data they had gathered at Halley Station on the Brunt Ice Shelf discovered the existence of a hole in this layer. It was eventually determined that the destruction of the ozone was caused by chlorofluorocarbons (CFCs) emitted by human products. With the ban of CFCs in the Montreal Protocol of 1989, climate projections indicate that the ozone layer will return to 1980 levels between 2050 and 2070.

Bomber crews already had some experience with these types of systems due to the deployment of the Lorenz beam, a commercial blind-landing aid which allowed aircraft to land at night or in bad weather. The Germans developed the short-range Lorenz system into the Knickebein aid, a system which used two Lorenz beams with much stronger signal transmissions. The concept was the same as the Lorenz system. Two aerials were rotated for the two converging beams which were pointed to cross directly over the target. The German bombers would attach themselves to either beam and fly along it until they started to pick up the signal from the other beam. When a continuous sound was heard from the second beam the crew knew they were above the target and began dropping their bombs.

Question: What did the Lorenz beam allow aircraft to do?
Answer: land at night or in bad weather.

Strong aftershocks continued to strike even months after the main quake. On May 25, an aftershock of 6.0 Mw (6.4 Ms according to CEA) hit northeast of the original earthquake's epicenter, in Qingchuan County, Sichuan, causing eight deaths, 1000 injuries, and destroying thousands of buildings. On May 27, two aftershocks, one 5.2 Mw in Qingchuan County and one 5.7 Mw in Ningqiang County, Shaanxi, led to the collapse of more than 420,000 homes and injured 63 people. The same area suffered two more aftershocks of 5.6 and 6.0 Ms (5.8 and 5.5 Mw, respectively, according to USGS) on July 23, resulting in 1 death, 6 serious injuries, collapse of hundreds of homes and damaging kilometers of highways. Pingwu County and Beichuan County, Sichuan, also northeast of Wenchuan and close to the epicenter of a 7.2 Ms earthquake in 1976, suffered a 6.1 Ms aftershock (5.7 Mw according to USGS) on August 1; it caused 2 deaths, 345 injuries, collapse of 707 homes, damages to over 1,000 homes, and blocked 25 kilometres (16 mi) of country roads. As late as August 5, yet another aftershock of 6.1 Ms (6.2 Mw according to USGS) hit Qingchuan, Sichuan, causing 1 death, 32 injuries, telecommunication interruptions, and widespread hill slides blocking roads in the area including a national highway.

Dell's reputation for poor customer service, since 2002, which was exacerbated as it moved call centres offshore and as its growth outstripped its technical support infrastructure, came under increasing scrutiny on the Web. The original Dell model was known for high customer satisfaction when PCs sold for thousands but by the 2000s, the company could not justify that level of service when computers in the same lineup sold for hundreds. Rollins responded by shifting Dick Hunter from head of manufacturing to head of customer service. Hunter, who noted that Dell's DNA of cost-cutting "got in the way," aimed to reduce call transfer times and have call center representatives resolve inquiries in one call. By 2006, Dell had spent $100 million in just a few months to improve on this, and rolled out DellConnect to answer customer inquiries more quickly. In July 2006, the company started its Direct2Dell blog, and then in February 2007, Michael Dell launched IdeaStorm.com, asking customers for advice including selling Linux computers and reducing the promotional "bloatware" on PCs. These initiatives did manage to cut the negative blog posts from 49% to 22%, as well as reduce the "Dell Hell" prominent on Internet search engines.

Denial of service attacks are designed to make a machine or network resource unavailable to its intended users. Attackers can deny service to individual victims, such as by deliberately entering a wrong password enough consecutive times to cause the victim account to be locked, or they may overload the capabilities of a machine or network and block all users at once. While a network attack from a single IP address can be blocked by adding a new firewall rule, many forms of Distributed denial of service (DDoS) attacks are possible, where the attack comes from a large number of points – and defending is much more difficult. Such attacks can originate from the zombie computers of a botnet, but a range of other techniques are possible including reflection and amplification attacks, where innocent systems are fooled into sending traffic to the victim.

Question: What does DDoS stand for?
Answer: Distributed denial of service.

Peer groups are essential to social and general development. Communication with peers increases significantly during adolescence and peer relationships become more intense than in other stages  and more influential to the teen, affecting both the decisions and choices being made. High quality friendships may enhance children's development regardless of the characteristics of those friends. As children begin to bond with various people and create friendships, it later helps them when they are adolescent and sets up the framework for adolescence and peer groups. Peer groups are especially important during adolescence, a period of development characterized by a dramatic increase in time spent with peers and a decrease in adult supervision. Adolescents also associate with friends of the opposite sex much more than in childhood and tend to identify with larger groups of peers based on shared characteristics. It is also common for adolescents to use friends as coping devices in different situations. A three-factor structure of dealing with friends including avoidance, mastery, and nonchalance has shown that adolescents use friends as coping devices with social stresses.

Question: Does communication with peers increase or decrease during adolescence?
Answer: increases.

From the 1950s on, many areas of the Great Plains have become productive crop-growing areas because of extensive irrigation on large landholdings. The United States is a major exporter of agricultural products. The southern portion of the Great Plains lies over the Ogallala Aquifer, a huge underground layer of water-bearing strata dating from the last ice age. Center pivot irrigation is used extensively in drier sections of the Great Plains, resulting in aquifer depletion at a rate that is greater than the ground's ability to recharge.

State banquets also take place in the Ballroom; these formal dinners are held on the first evening of a state visit by a foreign head of state. On these occasions, for up to 170 guests in formal "white tie and decorations", including tiaras, the dining table is laid with the Grand Service, a collection of silver-gilt plate made in 1811 for the Prince of Wales, later George IV. The largest and most formal reception at Buckingham Palace takes place every November when the Queen entertains members of the diplomatic corps. On this grand occasion, all the state rooms are in use, as the royal family proceed through them, beginning at the great north doors of the Picture Gallery. As Nash had envisaged, all the large, double-mirrored doors stand open, reflecting the numerous crystal chandeliers and sconces, creating a deliberate optical illusion of space and light.

In lossy audio compression, methods of psychoacoustics are used to remove non-audible (or less audible) components of the audio signal. Compression of human speech is often performed with even more specialized techniques; speech coding, or voice coding, is sometimes distinguished as a separate discipline from audio compression. Different audio and speech compression standards are listed under audio coding formats. Voice compression is used in internet telephony, for example, audio compression is used for CD ripping and is decoded by the audio players.

Miami and its suburbs are located on a broad plain between the Florida Everglades to the west and Biscayne Bay to the east, which also extends from Florida Bay north to Lake Okeechobee. The elevation of the area never rises above 40 ft (12 m) and averages at around 6 ft (1.8 m) above mean sea level in most neighborhoods, especially near the coast. The highest undulations are found along the coastal Miami Rock Ridge, whose substrate underlies most of the eastern Miami metropolitan region. The main portion of the city lies on the shores of Biscayne Bay which contains several hundred natural and artificially created barrier islands, the largest of which contains Miami Beach and South Beach. The Gulf Stream, a warm ocean current, runs northward just 15 miles (24 km) off the coast, allowing the city's climate to stay warm and mild all year.

Katō Kiyomasa was one of the most powerful and well-known lords of the Sengoku Era. He commanded most of Japan's major clans during the invasion of Korea (1592–1598). In a handbook he addressed to "all samurai, regardless of rank" he told his followers that a warrior's only duty in life was to "...grasp the long and the short swords and to die". He also ordered his followers to put forth great effort in studying the military classics, especially those related to loyalty and filial piety. He is best known for his quote: "If a man does not investigate into the matter of Bushido daily, it will be difficult for him to die a brave and manly death. Thus it is essential to engrave this business of the warrior into one's mind well."

The term high definition once described a series of television systems originating from August 1936; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and nations to create true "HDTV" spanned the entire 20th century, as each new system became more HD than the last.In the beginning of the 21st century, this race has continued with 4k, 5k and current 8K systems.

Also emerging during this period was New York's no wave movement, a short-lived art and music scene that began in part as a reaction against punk's recycling of traditionalist rock tropes and often reflected an abrasive, confrontational and nihilistic worldview. No wave musicians such as the Contortions, Teenage Jesus and the Jerks, Mars, DNA, Theoretical Girls and Rhys Chatham instead experimented with noise, dissonance and atonality in addition to non-rock styles. The former four groups were included on the Eno-produced No New York compilation, often considered the quintessential testament to the scene. The no wave-affiliated label ZE Records was founded in 1978, and would also produce acclaimed and influential compilations in subsequent years.
