Kurita passed through San Bernardino Strait at 03:00 on 25 October and headed along the coast of Samar. The only thing standing in his path were three groups (Taffy 1, 2 and 3) of the Seventh Fleet, commanded by Admiral Thomas Kinkaid. Each group had six escort carriers, with a total of more than 500 planes, and seven or eight destroyers or destroyer escorts (DE). Kinkaid still believed that Lee's force was guarding the north, so the Japanese had the element of surprise when they attacked Taffy 3 at 06:45. Kurita mistook the Taffy carriers for large fleet carriers and thought he had the whole Third Fleet in his sights. Since escort carriers stood little chance against a battleship, Adm. Clifton Sprague directed the carriers of Taffy 3 to turn and flee eastward, hoping that bad visibility would reduce the accuracy of Japanese gunfire, and used his destroyers to divert the Japanese battleships. The destroyers made harassing torpedo attacks against the Japanese. For ten minutes Yamato was caught up in evasive action. Two U.S. destroyers and a DE were sunk, but they had bought enough time for the Taffy groups to launch planes. Taffy 3 turned and fled south, with shells scoring hits on some of its carriers and sinking one of them. The superior speed of the Japanese force allowed it to draw closer and fire on the other two Taffy groups. However, at 09:20 Kurita suddenly turned and retreated north. Signals had disabused him of the notion that he was attacking the Third Fleet, and the longer Kurita continued to engage, the greater the risk of major air strikes. Destroyer attacks had broken the Japanese formations, shattering tactical control. Three of Kurita's heavy cruisers had been sunk and another was too damaged to continue the fight. The Japanese retreated through the San Bernardino Strait, under continuous air attack. The Battle of Leyte Gulf was over; and a large part of the Japanese surface fleet destroyed.

When did Kurita pass through the San Bernardino Strait?
Where did Kurit head after passing through the San Bernardino Strait?
Admiral Kincaid commanded what three groups of the Seventh Fleet?
What broke the Japanes formations under Kurita?
How many of Kurita's heavy cruisers were sunk?
Kurita's "Center Force" consisted of five battleships, 12 cruisers and 13 destroyers. It included the two largest battleships ever built: Yamato and Musashi. As they passed Palawan Island after midnight on 23 October the force was spotted, and U.S. submarines sank two cruisers. On 24 October, as Kurita's force entered the Sibuyan Sea, USS Intrepid and USS Cabot launched 260 planes, which scored hits on several ships. A second wave of planes scored many direct hits on Musashi. A third wave, from USS Enterprise and USS Franklin hit Musashi with 11 bombs and eight torpedoes. Kurita retreated but in the evening turned around to head for San Bernardino Strait. Musashi sank at about 19:30.

LED lamps have been advocated as the newest and best environmental lighting method. According to the Energy Saving Trust, LED lamps use only 10% power compared to a standard incandescent bulb, where compact fluorescent lamps use 20% and energy saving halogen lamps 70%. The lifetime is also much longer — up to 50,000 hours. A downside is still the initial cost, which is higher than that of compact fluorescent lamps.

Questions:
How much more power does a standard incandescent bulb use compared to LED?
What is the average lifetime of a CFL?
What is the average lifetime of a CFL?
How much power does a halogen lamp save compared to a standard blub?
LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.

Questions:
What quality has LEDs been used as?
What LED has the flattest I/V curve above the knee?
What LEDs have a very steep I/V curve?
LED forward voltage is more current-dependent than what diode?
Zener diodes below what voltage are not widely available?
LEDs have been developed by Seoul Semiconductor that can operate on AC power without the need for a DC converter. For each half-cycle, part of the LED emits light and part is dark, and this is reversed during the next half-cycle. The efficacy of this type of HP-LED is typically 40 lm/W. A large number of LED elements in series may be able to operate directly from line voltage. In 2009, Seoul Semiconductor released a high DC voltage LED, named as 'Acrich MJT', capable of being driven from AC power with a simple controlling circuit. The low-power dissipation of these LEDs affords them more flexibility than the original AC LED design.

Questions:
What company has developed LEDs that can operate on AC power?
What is the efficacy of an AC powered HP-LED?
When did Seoul Semiconductor release the first high DC voltage LED?
What is so good about ac powered HP-LEDs?
What did Seoul Semiconductor name their ac powered HP-LED?
La Cueva De Las Ventanas (The Cave of Windows), a series of cliff dwellings along an important trade route, and Las Jarillas Cave scrambled along the canyons of the Sierra Madre in Northwestern Chihuahua date between AD 1205 and 1260 and belong to the Paquimé culture. Cuarenta Casas is thought to have been a branch settlement from Paquime to protect the trade route from attack. Archaeologists believe the civilization began to decline during the 13th century and by the 15th century the inhabitants of Paquime sought refuge in the Sierra Madre Occidental while others are thought to have emigrated north and joined the Ancestral Pueblo peoples. According to anthropologist current natives tribes (Yaqui, Mayo, Opata, and Tarahumara) are descendants of the Casas Grandes culture.

La Diablada Carnival takes place in Oruro in central Bolivia. It is celebrated in honor of the miners' patron saint, Vírgen de Socavon (the Virgin of the Tunnels). Over 50 parade groups dance, sing and play music over a five kilometre-long course. Participants dress up as demons, devils, angels, Incas and Spanish conquistadors. Dances include caporales and tinkus. The parade runs from morning until late at night, 18 hours a day, 3 days before Ash Wednesday. It was declared the 2001 "Masterpieces of Oral Heritage and Intangible Heritage of Humanity" for UNESCO. Throughout the country celebrations are held involving traditional rhythms and water parties. In Santa Cruz de la Sierra, on the east side of the country, tropical weather allows a Brazilian-type Carnival, with Comparsas dancing traditional songs in matching uniforms.

Labour improved its performance in 1987, gaining 20 seats and so reducing the Conservative majority from 143 to 102. They were now firmly re-established as the second political party in Britain as the Alliance had once again failed to make a breakthrough with seats. A merger of the SDP and Liberals formed the Liberal Democrats. Following the 1987 election, the National Executive Committee resumed disciplinary action against members of Militant, who remained in the party, leading to further expulsions of their activists and the two MPs who supported the group.

Questions:
How many more seats did LAbour get in 1987?

Lack of meaningful alternatives, such as affordable schools and quality education, according to ILO, is another major factor driving children to harmful labour. Children work because they have nothing better to do. Many communities, particularly rural areas where between 60–70% of child labour is prevalent, do not possess adequate school facilities. Even when schools are sometimes available, they are too far away, difficult to reach, unaffordable or the quality of education is so poor that parents wonder if going to school is really worth it.

Questions:
What is the main reason for children today to be in the work force?
Do the poor families put a value on education?
What community has the most prevalency for child labour?
Lack of political unity within Greece resulted in frequent conflict between Greek states. The most devastating intra-Greek war was the Peloponnesian War (431–404 BC), won by Sparta and marking the demise of the Athenian Empire as the leading power in ancient Greece. Both Athens and Sparta were later overshadowed by Thebes and eventually Macedon, with the latter uniting the Greek world in the League of Corinth (also known as the Hellenic League or Greek League) under the guidance of Phillip II, who was elected leader of the first unified Greek state in history.

Questions:
The war from 431-404 BC is known as what? 
What often caused strife between Greek states?

Lactase is an enzyme that breaks down the disaccharide lactose to its component parts, glucose and galactose. Glucose and galactose can be absorbed by the small intestine. Approximately 65 percent of the adult population produce only small amounts of lactase and are unable to eat unfermented milk-based foods. This is commonly known as lactose intolerance. Lactose intolerance varies widely by ethnic heritage; more than 90 percent of peoples of east Asian descent are lactose intolerant, in contrast to about 5 percent of people of northern European descent.

Lafayette Park is a revitalized neighborhood on the city's east side, part of the Ludwig Mies van der Rohe residential district. The 78-acre (32 ha) development was originally called the Gratiot Park. Planned by Mies van der Rohe, Ludwig Hilberseimer and Alfred Caldwell it includes a landscaped, 19-acre (7.7 ha) park with no through traffic, in which these and other low-rise apartment buildings are situated. Immigrants have contributed to the city's neighborhood revitalization, especially in southwest Detroit. Southwest Detroit has experienced a thriving economy in recent years, as evidenced by new housing, increased business openings and the recently opened Mexicantown International Welcome Center.

Laing's definition of identity closely follows Erikson's, in emphasising the past, present and future components of the experienced self. He also develops the concept of the "metaperspective of self", i.e. the self's perception of the other's view of self, which has been found to be extremely important in clinical contexts such as anorexia nervosa. (Saunderson and O'Kane, 2005). Harré also conceptualises components of self/identity – the "person" (the unique being I am to myself and others) along with aspects of self (including a totality of attributes including beliefs about one's characteristics including life history), and the personal characteristics displayed to others.

Questions:
Whose definition of identity closely follows Erikson's?
One person's perception of another's perception is an example of what concept?
The person, aspects of self, and personal characteristics displayed to others are components of what?
Laird writes that Altan Khan abolished the native Mongol practices of shamanism and blood sacrifice, while the Mongol princes and subjects were coerced by Altan to convert to Gelug Buddhism—or face execution if they persisted in their shamanistic ways. Committed to their religious leader, Mongol princes began requesting the Dalai Lama to bestow titles on them, which demonstrated "the unique fusion of religious and political power" wielded by the Dalai Lama, as Laird writes. Kolmaš states that the spiritual and secular Mongol-Tibetan alliance of the 13th century was renewed by this alliance constructed by Altan Khan and Sönam Gyatso. Van Praag writes that this restored the original Mongol patronage of a Tibetan lama and "to this day, Mongolians are among the most devout followers of the Gelugpa and the Dalai Lama." Angela F. Howard writes that this unique relationship not only provided the Dalai Lama and Panchen Lama with religious and political authority in Tibet, but that Altan Khan gained "enormous power among the entire Mongol population."

Questions:
What practice did Altan Khan put to an end?
Who did Altan Khan persuade to convert to Gelug Buddhism?
What did Altan Khan threaten the Mongol princes and subjects with if they did not convert?
Who did the Mongol princes ask to grant them titles?
Why did the Mongol princes ask for titles?
Laird writes that the Ming appointed titles to eastern Tibetan princes, and that "these alliances with eastern Tibetan principalities are the evidence China now produces for its assertion that the Ming ruled Tibet," despite the fact that the Ming did not send an army to replace the Mongols after they left Tibet. Yiu Yung-chin states that the furthest western extent of the Ming dynasty's territory was Gansu, Sichuan, and Yunnan while "the Ming did not possess Tibet."

Questions:
Who did the Ming appoint titles to?
What didn't the Ming send to replace the Mongols when they left Tibet?
What does Yiu Yung-chin claim the Ming did not possess?
Lamps designed for different voltages have different luminous efficacy. For example, a 100-watt, 120-volt lamp will produce about 17.1 lumens per watt. A lamp with the same rated lifetime but designed for 230 V would produce only around 12.8 lumens per watt, and a similar lamp designed for 30 volts (train lighting) would produce as much as 19.8 lumens per watt. Lower voltage lamps have a thicker filament, for the same power rating. They can run hotter for the same lifetime before the filament evaporates.

Questions:
How many lumens per watt does a typical 100-watt, 120-volt lamp produce?
How many lumens per watt does a typical train light produce?
How does filament size relate to voltage level?
What is the effect of a thicker filament on bulb temperature?
Lancashire emerged as a major commercial and industrial region during the Industrial Revolution. Manchester and Liverpool grew into its largest cities, dominating global trade and the birth of modern capitalism. The county contained several mill towns and the collieries of the Lancashire Coalfield. By the 1830s, approximately 85% of all cotton manufactured worldwide was processed in Lancashire. Accrington, Blackburn, Bolton, Burnley, Bury, Chorley, Colne, Darwen, Nelson, Oldham, Preston, Rochdale and Wigan were major cotton mill towns during this time. Blackpool was a centre for tourism for the inhabitants of Lancashire's mill towns, particularly during wakes week.

Lancashire had a lively culture of choral and classical music, with very large numbers of local church choirs from the 17th century, leading to the foundation of local choral societies from the mid-18th century, often particularly focused on performances of the music of Handel and his contemporaries. It also played a major part in the development of brass bands which emerged in the county, particularly in the textile and coalfield areas, in the 19th century. The first open competition for brass bands was held at Manchester in 1853, and continued annually until the 1980s. The vibrant brass band culture of the area made an important contribution to the foundation and staffing of the Hallé Orchestra from 1857, the oldest extant professional orchestra in the United Kingdom. The same local musical tradition produced eminent figures such as Sir William Walton (1902–88), son of an Oldham choirmaster and music teacher, Sir Thomas Beecham (1879–1961), born in St. Helens, who began his career by conducting local orchestras and Alan Rawsthorne (1905–71) born in Haslingden. The conductor David Atherton, co-founder of the London Sinfonietta, was born in Blackpool in 1944. Lancashire also produced more populist figures, such as early musical theatre composer Leslie Stuart (1863–1928), born in Southport, who began his musical career as organist of Salford Cathedral.

Lancashire has a long and highly productive tradition of music making. In the early modern era the county shared in the national tradition of balladry, including perhaps the finest border ballad, "The Ballad of Chevy Chase", thought to have been composed by the Lancashire-born minstrel Richard Sheale. The county was also a common location for folk songs, including "The Lancashire Miller", "Warrington Ale" and "The soldier's farewell to Manchester", while Liverpool, as a major seaport, was the subject of many sea shanties, including "The Leaving of Liverpool" and "Maggie May", beside several local Wassailing songs. In the Industrial Revolution changing social and economic patterns helped create new traditions and styles of folk song, often linked to migration and patterns of work. These included processional dances, often associated with rushbearing or the Wakes Week festivities, and types of step dance, most famously clog dancing.

Questions:
Who was "The Ballad of Chevy Chase" composed by?
Where was Richard Sheale from?
What did the county share with it's national traditions?
What is Lancashire's long and productive tradition?

Lancashire has a mostly comprehensive system with four state grammar schools. Not including sixth form colleges, there are 77 state schools (not including Burnley's new schools) and 24 independent schools. The Clitheroe area has secondary modern schools. Sixth form provision is limited at most schools in most districts, with only Fylde and Lancaster districts having mostly sixth forms at schools. The rest depend on FE colleges and sixth form colleges, where they exist. South Ribble has the largest school population and Fylde the smallest (only three schools). Burnley's schools have had a new broom and have essentially been knocked down and started again in 2006. There are many Church of England and Catholic faith schools in Lancashire.

Lancashire is smaller than its historical extent following a major reform of local government. In 1889, the administrative county of Lancashire was created, covering the historical county except for the county boroughs such as Blackburn, Burnley, Barrow-in-Furness, Preston, Wigan, Liverpool and Manchester. The area served by the Lord-Lieutenant (termed now a ceremonial county) covered the entirety of the administrative county and the county boroughs, and was expanded whenever boroughs annexed areas in neighbouring counties such as Wythenshawe in Manchester south of the River Mersey and historically in Cheshire, and southern Warrington. It did not cover the western part of Todmorden, where the ancient border between Lancashire and Yorkshire passes through the middle of the town.

Questions:
When was the administrative county of Lancashire created?
What is the area served by the Lord-Lieutenant called now?
Where is the ancient border between Lancashire and Yorkshire located?
Why is Lancashire smaller than its historical extent?
What area is covered by the Lord-Lieutenant?
Lancashire produced well known teams in super league such as St Helens, Wigan, and Warrington. The county was once the focal point for many of the sport's professional competitions including the Lancashire League competition which ran from 1895 to 1970, and the Lancashire County Cup which was abandoned in 1993. Rugby League has also seen a representative fixture between Lancashire and Yorkshire contested 89 times since its inception in 1895. Currently there are several rugby league teams that are based within the ceremonial county which include Blackpool Panthers, East Lancashire Lions, Blackpool Sea Eagles, Bamber Bridge, Leyland Warriors, Chorley Panthers, Blackpool Stanley, Blackpool Scorpions and Adlington Rangers.

Large brushes are desired for a larger brush contact area to maximize motor output, but small brushes are desired for low mass to maximize the speed at which the motor can run without the brushes excessively bouncing and sparking. (Small brushes are also desirable for lower cost.) Stiffer brush springs can also be used to make brushes of a given mass work at a higher speed, but at the cost of greater friction losses (lower efficiency) and accelerated brush and commutator wear. Therefore, DC motor brush design entails a trade-off between output power, speed, and efficiency/wear.

Questions:
What are large brushes favorable for?
Whate are small brushes favorable for?
What type of brushes are cheapest?
How can the speed of larger brushes be increased?
Besides wear, what is a downside of stiff brush springs?
Large masses, such as ice sheets or glaciers, can depress the crust of the Earth into the mantle. The depression usually totals a third of the ice sheet or glacier's thickness. After the ice sheet or glacier melts, the mantle begins to flow back to its original position, pushing the crust back up. This post-glacial rebound, which proceeds very slowly after the melting of the ice sheet or glacier, is currently occurring in measurable amounts in Scandinavia and the Great Lakes region of North America.

Questions:
Where is post-glacial rebound occuring most?
What has the ability to depress the crust of the Earth into the mantle?
With what speed does post-glacial rebound occur?
How much of a glacier's thickness is usually involved during crust depression into the mantle?
Large numbers of Bolivian highland peasants retained indigenous language, culture, customs, and communal organization throughout the Spanish conquest and the post-independence period. They mobilized to resist various attempts at the dissolution of communal landholdings and used legal recognition of "empowered caciques" to further communal organization. Indigenous revolts took place frequently until 1953. While the National Revolutionary Movement government begun in 1952 discouraged self-identification as indigenous (reclassifying rural people as campesinos, or peasants), renewed ethnic and class militancy re-emerged in the Katarista movement beginning in the 1970s. Lowland indigenous peoples, mostly in the east, entered national politics through the 1990 March for Territory and Dignity organized by the CIDOB confederation. That march successfully pressured the national government to sign the ILO Convention 169 and to begin the still-ongoing process of recognizing and titling indigenous territories. The 1994 Law of Popular Participation granted "grassroots territorial organizations" that are recognized by the state certain rights to govern local areas.

Questions:
Who retained indigenous language and culture after the Spanish conquest?
What re-emerged during the Katarista movement in the 1970s?
What did the highland peasants resist attempts at?
What took place frequently until 1953?
What march successfully pressured the national government to sign the ILO Convetion 169?
Large quantities of H 2 are needed in the petroleum and chemical industries. The largest application of H 2 is for the processing ("upgrading") of fossil fuels, and in the production of ammonia. The key consumers of H 2 in the petrochemical plant include hydrodealkylation, hydrodesulfurization, and hydrocracking. H 2 has several other important uses. H 2 is used as a hydrogenating agent, particularly in increasing the level of saturation of unsaturated fats and oils (found in items such as margarine), and in the production of methanol. It is similarly the source of hydrogen in the manufacture of hydrochloric acid. H 2 is also used as a reducing agent of metallic ores.

Questions:
Where are large quantities of H2 needed?
What are the consumers of H2 in petrochemical plant?

Larger SAMs may be deployed in fixed launchers, but can be towed/re-deployed at will. The SAMs launched by individuals are known in the United States as the Man-Portable Air Defence Systems (MANPADS). MANPADS of the former Soviet Union have been exported around the World, and can be found in use by many armed forces. Targets for non-ManPAD SAMs will usually be acquired by air-search radar, then tracked before/while a SAM is "locked-on" and then fired. Potential targets, if they are military aircraft, will be identified as friend or foe before being engaged. The developments in the latest and relatively cheap short-range missiles have begun to replace autocannons in this role.

Questions:
What can be deployed in fixed launchers but re-deploy at will?
What are the SAMs called that are launched by individuals in the US?
What does MANPADS mean?
How are targets aquired for non-ManPAD SAMs?
Short range missiles are replacing what weapons?
Larry Christenson, a Lutheran theologian based in San Pedro, California, did much in the 1960s and 1970s to interpret the charismatic movement for Lutherans. A very large annual conference regarding that matter was held in Minneapolis. Charismatic Lutheran congregations in Minnesota became especially large and influential; especially "Hosanna!" in Lakeville, and North Heights in St. Paul. The next generation of Lutheran charismatics cluster around the Alliance of Renewal Churches. There is considerable charismatic activity among young Lutheran leaders in California centered around an annual gathering at Robinwood Church in Huntington Beach. Richard A. Jensen's Touched by the Spirit published in 1974, played a major role of the Lutheran understanding to the charismatic movement.

Questions:
Who helped Lutherans understand the charismatic movement in the 1960s?
In what state did charismatic Lutheran congregations grow to be quite large?
Where is an annual event that has quite a bit of charismatic activity?
What was published in 1974?

Larry Heard, a.k.a. "Mr. Fingers", claims that the term "house" became popular due to many of the early DJs creating music in their own homes using synthesizers and drum machines such as the Roland TR-808, TR-909, and the TB 303.[citation needed] These synthesizers were used to create a house subgenre called acid house.

Questions:
What was the stage name of Larry Heard?
Why did the term house become popular? 
what are the Roland TR-808, TR-909, and TB 303 examples of?
synthesizers were used to create what house subgenre?
what was the real name of Mr. Fingers?
LaserDisc did not have high market penetration in North America due to the high cost of the players and discs, which were far more expensive than VHS players and tapes, and due to marketplace confusion with the technologically inferior CED, which also went by the name Videodisc. While the format was not widely adopted by North American consumers, it was well received among videophiles due to the superior audio and video quality compared to VHS and Betamax tapes, finding a place in nearly one million American homes by the end of 1990. The format was more popular in Japan than in North America because prices were kept low to ensure adoption, resulting in minimal price differences between VHS tapes and the higher quality LaserDiscs, helping ensure that it quickly became the dominant consumer video format in Japan. Anime collectors in every country the LD format was released, which includes both North America and Japan, also quickly became familiar with this format, and sought the higher video and sound quality of LaserDisc and the availability of numerous titles not available on VHS. LaserDiscs were also popular alternatives to videocassettes among movie enthusiasts in the more affluent regions of South East Asia, such as Singapore, due to their high integration with the Japanese export market and the disc-based media's superior longevity compared to videocassette, especially in the humid conditions endemic to that area of the world.

Questions:
Why didn't LaserDiscs become popular in North America?
By 1990, how many American homes were estimated to use LD?
Why were LaserDiscs more popular in Japan?
Which format was more popular in high humidity areas such as Singapore?
LaserDisc had a number of advantages over VHS. It featured a far sharper picture with a horizontal resolution of 425 TVL lines for NTSC and 440 TVL lines for PAL discs, while VHS featured only 240 TVL lines with NTSC. It could handle analog and digital audio where VHS was mostly analog only (VHS can have PCM audio in professional applications but is uncommon), and the NTSC discs could store multiple audio tracks. This allowed for extras like director's commentary tracks and other features to be added onto a film, creating "Special Edition" releases that would not have been possible with VHS. Disc access was random and chapter based, like the DVD format, meaning that one could jump to any point on a given disc very quickly. By comparison, VHS would require tedious rewinding and fast-forwarding to get to specific points.

Questions:
How many horizontal TVL lines did LaserDisc have in comparison to VHS's 240?
Which medium was chapter based like DVD format, Laserdisc or VHS?
Which medium allowed for multiple audio tracks, Laserdisc or VHS?
LaserDisc players can provide a great degree of control over the playback process. Unlike many DVD players, the transport mechanism always obeys commands from the user: pause, fast-forward, and fast-reverse commands are always accepted (barring, of course, malfunctions). There were no "User Prohibited Options" where content protection code instructs the player to refuse commands to skip a specific part (such as fast forwarding through copyright warnings). (Some DVD players, particularly higher-end units, do have the ability to ignore the blocking code and play the video without restrictions, but this feature is not common in the usual consumer market.)

Questions:
How does LaserDisc operation vary from DVD?
What are "User Protected Options" on DVDs?
Where are User Protected Options commonly found on DVDs?
Which format, LaserDisc or DVD, gives the user the most control over playback?
LaserDisc was a composite video format: the luminance (black and white) and chrominance (color) information were transmitted in one signal, separated by the receiver. While good comb filters can do so adequately, these two signals cannot be completely separated. On DVDs, data is stored in the form of digital blocks which make up each independent frame. The signal produced is dependent on the equipment used to master the disc. Signals range from composite and split, to YUV and RGB. Depending upon which format is used, this can result in far higher fidelity, particularly at strong color borders or regions of high detail (especially if there is moderate movement in the picture) and low-contrast details like skin tones, where comb filters almost inevitably smudge some detail.

Questions:
How is data stored on DVDs?
What device seperated the black and white and color signals in LaserDiscs?
In what areas are comb filters most likely to lose detail?
Are comb filters exact, or is some data smudged?
LaserDisc was first available on the market, in Atlanta, Georgia, on December 15, 1978, two years after the introduction of the VHS VCR, and four years before the introduction of the CD (which is based on laser disc technology). Initially licensed, sold, and marketed as MCA DiscoVision (also known as simply "DiscoVision") in North America in 1978, the technology was previously referred to internally as Optical Videodisc System, Reflective Optical Videodisc, Laser Optical Videodisc, and Disco-Vision (with a dash), with the first players referring to the format as "Video Long Play".

Questions:
Where was LaserDisc first available?
How many years after VHS was LaserDisk released?
Under what name was LaserDisc originally marketed?
How did the first viewers refer to the media?
LaserDisc's support for multiple audio tracks allowed for vast supplemental materials to be included on-disc and made it the first available format for "Special Edition" releases; the 1984 Criterion Collection edition of Citizen Kane is generally credited as being the first "Special Edition" release to home video,[citation needed] and for setting the standard by which future SE discs were measured. The disc provided interviews, commentary tracks, documentaries, still photographs, and other features for historians and collectors.

Questions:
LaserDisc was the first format to provide what type of releases to consumers?
What was the first "Special Edition" film to be released to home video?
What bonus features were available on the first home video "Special Edition"?
What feature, unique to LaserDisc, made bonus content possible?
LaserDiscs potentially had a much longer lifespan than videocassettes. Because the discs were read optically instead of magnetically, no physical contact needs to be made between the player and the disc, except for the player's clamp that holds the disc at its center as it is spun and read. As a result, playback would not wear the information-bearing part of the discs, and properly manufactured LDs would theoretically last beyond one's lifetime. By contrast, a VHS tape held all of its picture and sound information on the tape in a magnetic coating which is in contact with the spinning heads on the head drum, causing progressive wear with each use (though later in VHS's lifespan, engineering improvements allowed tapes to be made and played back without contact). Also, the tape was thin and delicate, and it was easy for a player mechanism, especially on a low quality or malfunctioning model, to mishandle the tape and damage it by creasing it, frilling (stretching) its edges, or even breaking it.

Questions:
Were Laserdiscs or VHS more durable in the long run?
Why is physical contact with a VHS tape less desirable than an optical reading?
Where do VHS tapes store their information?
LaserDiscs were initially cheaper than videocassettes to manufacture, because they lacked the moving parts and plastic outer shell that are necessary for VHS tapes to work, and the duplication process was much simpler. A VHS cassette has at least 14 parts including the actual tape while LaserDisc has one part with five or six layers. A disc can be stamped out in a matter of seconds whereas duplicating videotape required a complex bulk tape duplication mechanism and was a time-consuming process. However, by the end of the 1980s, average disc-pressing prices were over $5.00 per two-sided disc, due to the large amount of plastic material and the costly glass-mastering process needed to make the metal stamper mechanisms. Due to the larger volume of demand, videocassettes quickly became much cheaper to duplicate, costing as little as $1.00 by the beginning of the 1990s.

Questions:
Were Laserdiscs initially cheaper or more costly to produce than their VHS counterparts?
How many parts does a VHS tape have that must be manufactured?
How much did LaserDiscs cost to produce by the end of the 1980s?
How much did VHS cost to produce by the 1990s?
Lasers emitting in the green part of the spectrum are widely available to the general public in a wide range of output powers. Green laser pointers outputting at 532 nm (563.5 THz) are relatively inexpensive compared to other wavelengths of the same power, and are very popular due to their good beam quality and very high apparent brightness. The most common green lasers use diode pumped solid state (DPSS) technology to create the green light. An infrared laser diode at 808 nm is used to pump a crystal of neodymium-doped yttrium vanadium oxide (Nd:YVO4) or neodymium-doped yttrium aluminium garnet (Nd:YAG) and induces it to emit 281.76 THz (1064 nm). This deeper infrared light is then passed through another crystal containing potassium, titanium and phosphorus (KTP), whose non-linear properties generate light at a frequency that is twice that of the incident beam (563.5 THz); in this case corresponding to the wavelength of 532 nm ("green"). Other green wavelengths are also available using DPSS technology ranging from 501 nm to 543 nm. Green wavelengths are also available from gas lasers, including the helium–neon laser (543 nm), the Argon-ion laser (514 nm) and the Krypton-ion laser (521 nm and 531 nm), as well as liquid dye lasers. Green lasers have a wide variety of applications, including pointing, illumination, surgery, laser light shows, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons and bird control.

Lasers emitting in the red region of the spectrum have been available since the invention of the ruby laser in 1960. In 1962 the red helium–neon laser was invented, and these two types of lasers were widely used in many scientific applications including holography, and in education. Red helium–neon lasers were used commercially in LaserDisc players. The use of red laser diodes became widespread with the commercial success of modern DVD players, which use a 660 nm laser diode technology. Today, red and red-orange laser diodes are widely available to the public in the form of extremely inexpensive laser pointers. Portable, high-powered versions are also available for various applications. More recently, 671 nm diode-pumped solid state (DPSS) lasers have been introduced to the market for all-DPSS laser display systems, particle image velocimetry, Raman spectroscopy, and holography.

Last but not least the electric double-layer capacitor (now Supercapacitors) were invented. In 1957 H. Becker developed a "Low voltage electrolytic capacitor with porous carbon electrodes". He believed that the energy was stored as a charge in the carbon pores used in his capacitor as in the pores of the etched foils of electrolytic capacitors. Because the double layer mechanism was not known by him at the time, he wrote in the patent: "It is not known exactly what is taking place in the component if it is used for energy storage, but it leads to an extremely high capacity.".

Questions:
What are electric double-layer capacitors called today?
When were low voltage electrolytic capacitors with porous carbon electrodes invented?
Who invented low voltage electrolytic capacitors with porous carbon electrodes?
In what part of the capacitor did Becker believe the charge was being stored?
In what component of electrolytic capacitors did Becker believe was similar to the porous carbon electrodes?
Late Carboniferous and Early Permian insect orders include both extant groups, their stem groups, and a number of Paleozoic groups, now extinct. During this era, some giant dragonfly-like forms reached wingspans of 55 to 70 cm (22 to 28 in), making them far larger than any living insect. This gigantism may have been due to higher atmospheric oxygen levels that allowed increased respiratory efficiency relative to today. The lack of flying vertebrates could have been another factor. Most extinct orders of insects developed during the Permian period that began around 270 million years ago. Many of the early groups became extinct during the Permian-Triassic extinction event, the largest mass extinction in the history of the Earth, around 252 million years ago.

Questions:
In addition to Carboniferous, what other insect order is inclusive of extant groups, stem groups and Paleozoic groups?

What type of art did Courbet, Manet, Monet and Renoir create?
What was the purpose of the 1889 Universal Exposition?
Where was the Eiffel Tower revealed?

Latency results from the methods used to encode and decode the data. Some codecs will analyze a longer segment of the data to optimize efficiency, and then code it in a manner that requires a larger segment of data at one time to decode. (Often codecs create segments called a "frame" to create discrete data segments for encoding and decoding.) The inherent latency of the coding algorithm can be critical; for example, when there is a two-way transmission of data, such as with a telephone conversation, significant delays may seriously degrade the perceived quality.

Questions:
What results from methods used to encode and decode data?
What analyzes a statement of data to boost performance?
What creates segments called a "frame"?
Later Indian materialist Jayaraashi Bhatta (6th century) in his work Tattvopaplavasimha ("The upsetting of all principles") refuted the Nyaya Sutra epistemology. The materialistic Cārvāka philosophy appears to have died out some time after 1400. When Madhavacharya compiled Sarva-darśana-samgraha (a digest of all philosophies) in the 14th century, he had no Cārvāka/Lokāyata text to quote from, or even refer to.

Questions:
Name the title of the work by Jayaraashi Bhatta.
Which type of philosphy did not continue after 1400?
What is Sarva-darśana-samgraha?
Who wrote the Sarva-darśana-samgraha?
Later chapters provide evidence that evolution has occurred, supporting the idea of branching, adaptive evolution without directly proving that selection is the mechanism. Darwin presents supporting facts drawn from many disciplines, showing that his theory could explain a myriad of observations from many fields of natural history that were inexplicable under the alternate concept that species had been individually created. The structure of Darwin's argument showed the influence of John Herschel, whose philosophy of science maintained that a mechanism could be called a vera causa (true cause) if three things could be demonstrated: its existence in nature, its ability to produce the effects of interest, and its ability to explain a wide range of observations.

Questions:
What does Darwin do to show that his theory can support many theories that could not be explained by individual creation of species?
Whose scientific philosophy argued that a mechanism could be called a vera causa if three things could be shown as true?
What are the three things John Herschel maintains need to be shown to allow for a mechanism be called a true cause?
