Von Neumann introduced the study of rings of operators, through the von Neumann algebras. A von Neumann algebra is a *-algebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator. The von Neumann bicommutant theorem shows that the analytic definition is equivalent to a purely algebraic definition as an algebra of symmetries. The direct integral was introduced in 1949 by John von Neumann. One of von Neumann's analyses was to reduce the classification of von Neumann algebras on separable Hilbert spaces to the classification of factors.

Question: What was introduced in von Neumann algebras?
Answer: study of rings of operators.

In most taxonomies, the flowering plants are treated as a coherent group. The most popular descriptive name has been Angiospermae (Angiosperms), with Anthophyta ("flowering plants") a second choice. These names are not linked to any rank. The Wettstein system and the Engler system use the name Angiospermae, at the assigned rank of subdivision. The Reveal system treated flowering plants as subdivision Magnoliophytina (Frohne & U. Jensen ex Reveal, Phytologia 79: 70 1996), but later split it to Magnoliopsida, Liliopsida, and Rosopsida. The Takhtajan system and Cronquist system treat this group at the rank of division, leading to the name Magnoliophyta (from the family name Magnoliaceae). The Dahlgren system and Thorne system (1992) treat this group at the rank of class, leading to the name Magnoliopsida. The APG system of 1998, and the later 2003 and 2009 revisions, treat the flowering plants as a clade called angiosperms without a formal botanical name. However, a formal classification was published alongside the 2009 revision in which the flowering plants form the Subclass Magnoliidae.

 Sugar taken orally reduces the total crying time but not the duration of the first cry in newborns undergoing a painful procedure (a single lancing of the heel). It does not moderate the effect of pain on heart rate and a recent single study found that sugar did not significantly affect pain-related electrical activity in the brains of newborns one second after the heel lance procedure. Sweet oral liquid moderately reduces the incidence and duration of crying caused by immunization injection in children between one and twelve months of age.

Eisenhower told District of Columbia officials to make Washington a model for the rest of the country in integrating black and white public school children. He proposed to Congress the Civil Rights Act of 1957 and of 1960 and signed those acts into law. The 1957 act for the first time established a permanent civil rights office inside the Justice Department and a Civil Rights Commission to hear testimony about abuses of voting rights. Although both acts were much weaker than subsequent civil rights legislation, they constituted the first significant civil rights acts since 1875.

Coffeehouses were especially important to the spread of knowledge during the Enlightenment because they created a unique environment in which people from many different walks of life gathered and shared ideas. They were frequently criticized by nobles who feared the possibility of an environment in which class and its accompanying titles and privileges were disregarded. Such an environment was especially intimidating to monarchs who derived much of their power from the disparity between classes of people. If classes were to join together under the influence of Enlightenment thinking, they might recognize the all-encompassing oppression and abuses of their monarchs and, because of their size, might be able to carry out successful revolts. Monarchs also resented the idea of their subjects convening as one to discuss political matters, especially those concerning foreign affairs - rulers thought political affairs to be their business only, a result of their supposed divine right to rule.

It was announced on 19 March 2015 that self-governance for the island would be revoked by the Commonwealth and replaced by a local council with the state of New South Wales providing services to the island. A reason given was that the island had never gained self-sufficiency and was being heavily subsidised by the Commonwealth, by $12.5 million in 2015 alone. It meant that residents would have to start paying Australian income tax, but they would also be covered by Australian welfare schemes such as Centrelink and Medicare.

An antenna (plural antennae or antennas), or aerial, is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an electric current oscillating at radio frequency (i.e. a high frequency alternating current (AC)) to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage at its terminals, that is applied to a receiver to be amplified.

---

Question: What process associated with antennas produces a high frequency alternating current?
Answer: transmission.

Race was asked differently in the Census 2000 in several other ways than previously. Most significantly, respondents were given the option of selecting one or more race categories to indicate racial identities. Data show that nearly seven million Americans identified as members of two or more races. Because of these changes, the Census 2000 data on race are not directly comparable with data from the 1990 census or earlier censuses. Use of caution is therefore recommended when interpreting changes in the racial composition of the US population over time.

Question: How many race categories were respondents able to select in the Census 2000?
Answer: one or more.

Throughout the Industrial Revolution, Plymouth grew as a commercial shipping port, handling imports and passengers from the Americas, and exporting local minerals (tin, copper, lime, china clay and arsenic) while the neighbouring town of Devonport became a strategic Royal Naval shipbuilding and dockyard town. In 1914 three neighbouring independent towns, viz., the county borough of Plymouth, the county borough of Devonport, and the urban district of East Stonehouse were merged to form a single County Borough. The combined town took the name of Plymouth which, in 1928, achieved city status. The city's naval importance later led to its targeting and partial destruction during World War II, an act known as the Plymouth Blitz. After the war the city centre was completely rebuilt and subsequent expansion led to the incorporation of Plympton and Plymstock along with other outlying suburbs in 1967.

The end of the 19th century marks the start of psychology as a scientific enterprise. The year 1879 is commonly seen as the start of psychology as an independent field of study. In that year Wilhelm Wundt founded the first laboratory dedicated exclusively to psychological research (in Leipzig). Other important early contributors to the field include Hermann Ebbinghaus (a pioneer in memory studies), Ivan Pavlov (who discovered classical conditioning), William James, and Sigmund Freud. Freud's influence has been enormous, though more as cultural icon than a force in scientific psychology.

Jean Macfarlane founded the University of California, Berkeley's Institute of Human Development, formerly called the Institute of Child Welfare, in 1927. The Institute was instrumental in initiating studies of healthy development, in contrast to previous work that had been dominated by theories based on pathological personalities. The studies looked at human development during the Great Depression and World War II, unique historical circumstances under which a generation of children grew up. The Oakland Growth Study, initiated by Harold Jones and Herbert Stolz in 1931, aimed to study the physical, intellectual, and social development of children in the Oakland area. Data collection began in 1932 and continued until 1981, allowing the researchers to gather longitudinal data on the individuals that extended past adolescence into adulthood. Jean Macfarlane launched the Berkeley Guidance Study, which examined the development of children in terms of their socioeconomic and family backgrounds. These studies provided the background for Glen Elder in the 1960s, to propose a life-course perspective of adolescent development. Elder formulated several descriptive principles of adolescent development. The principle of historical time and place states that an individual's development is shaped by the period and location in which they grow up. The principle of the importance of timing in one's life refers to the different impact that life events have on development based on when in one's life they occur. The idea of linked lives states that one's development is shaped by the interconnected network of relationships of which one is a part; and the principle of human agency asserts that one's life course is constructed via the choices and actions of an individual within the context of their historical period and social network.

The English sailor and adventurer William Adams (1564–1620) was the first Westerner to receive the dignity of samurai. The Shogun Tokugawa Ieyasu presented him with two swords representing the authority of a samurai, and decreed that William Adams the sailor was dead and that Anjin Miura (三浦按針), a samurai, was born. Adams also received the title of hatamoto (bannerman), a high-prestige position as a direct retainer in the Shogun's court. He was provided with generous revenues: "For the services that I have done and do daily, being employed in the Emperor's service, the Emperor has given me a living" (Letters). He was granted a fief in Hemi (逸見) within the boundaries of present-day Yokosuka City, "with eighty or ninety husbandmen, that be my slaves or servants" (Letters). His estate was valued at 250 koku. He finally wrote "God hath provided for me after my great misery", (Letters) by which he meant the disaster-ridden voyage that initially brought him to Japan.

Because most injuries sustained by adolescents are related to risky behavior (car crashes, alcohol, unprotected sex), a great deal of research has been done on the cognitive and emotional processes underlying adolescent risk-taking. In addressing this question, it is important to distinguish whether adolescents are more likely to engage in risky behaviors (prevalence), whether they make risk-related decisions similarly or differently than adults (cognitive processing perspective), or whether they use the same processes but value different things and thus arrive at different conclusions. The behavioral decision-making theory proposes that adolescents and adults both weigh the potential rewards and consequences of an action. However, research has shown that adolescents seem to give more weight to rewards, particularly social rewards, than do adults.

Question: Do adolescents or adults seem to give more weight to rewards?
Answer: adolescents.

The most influential publication of the Enlightenment was the Encyclopédie, compiled by Denis Diderot and (until 1759) by Jean le Rond d'Alembert and a team of 150 scientists and philosophers. It was published between 1751 and 1772 in thirty-five volumes, and spread the ideas of the Enlightenment across Europe and beyond. Other landmark publications were the Dictionnaire philosophique (Philosophical Dictionary, 1764) and Letters on the English (1733) written by Voltaire; Rousseau's Discourse on Inequality (1754) and The Social Contract (1762); and Montesquieu's Spirit of the Laws (1748). The ideas of the Enlightenment played a major role in inspiring the French Revolution, which began in 1789. After the Revolution, the Enlightenment was followed by an opposing intellectual movement known as Romanticism.

The Hephthalites (or Ephthalites), also known as the White Huns, were a nomadic confederation in Central Asia during the late antiquity period. The White Huns established themselves in modern-day Afghanistan by the first half of the 5th century. Led by the Hun military leader Toramana, they overran the northern region of Pakistan and North India. Toramana's son Mihirakula, a Saivite Hindu, moved up to near Pataliputra to the east and Gwalior to the central India. Hiuen Tsiang narrates Mihirakula's merciless persecution of Buddhists and destruction of monasteries, though the description is disputed as far as the authenticity is concerned. The Huns were defeated by the Indian kings Yasodharman of Malwa and Narasimhagupta in the 6th century. Some of them were driven out of India and others were assimilated in the Indian society.

New developments in Judaism often transcend differences in religious practice between Ashkenazi and Sephardic Jews. In North American cities, social trends such as the chavurah movement, and the emergence of "post-denominational Judaism" often bring together younger Jews of diverse ethnic backgrounds. In recent years, there has been increased interest in Kabbalah, which many Ashkenazi Jews study outside of the Yeshiva framework. Another trend is the new popularity of ecstatic worship in the Jewish Renewal movement and the Carlebach style minyan, both of which are nominally of Ashkenazi origin.

Question: Which new trend has been associated with the Jewish Renewal movement?
Answer: ecstatic worship.

The "photoelectrons" emitted as a result of the photoelectric effect have a certain kinetic energy, which can be measured. This kinetic energy (for each photoelectron) is independent of the intensity of the light, but depends linearly on the frequency; and if the frequency is too low (corresponding to a photon energy that is less than the work function of the material), no photoelectrons are emitted at all, unless a plurality of photons, whose energetic sum is greater than the energy of the photoelectrons, acts virtually simultaneously (multiphoton effect)  Assuming the frequency is high enough to cause the photoelectric effect, a rise in intensity of the light source causes more photoelectrons to be emitted with the same kinetic energy, rather than the same number of photoelectrons to be emitted with higher kinetic energy.

---

Question: If the photoelectric effect is occuring, increasing the intensity of the light source causes what?
Answer: more photoelectrons to be emitted with the same kinetic energy.
