Article: Taco
Section: Soft-shell tacos

Question: How are soft tacos made?

Traditionally, soft-shelled tacos referred to corn tortillas that were cooked to a softer state than a hard taco - usually by grilling or steaming.
More recently the term has come to include flour tortilla based tacos mostly from large manufacturers and restaurant chains.
In this context, "soft tacos" are tacos made with wheat flour tortillas and filled with the same ingredients as a hard taco.

Article: Dairy product
Section: Abstract

Question: Any milk of mammals is considered to be what?

A dairy product is food produced from the milk of mammals.
Dairy products are usually high energy-yielding food products.
A production plant for the processing of milk is called a dairy or a dairy factory.
Apart from breastfed infants, the human consumption of dairy products is sourced primarily from the milk of cows, yet goats, sheep, yaks, horses, camels, and other mammals are other sources of dairy products consumed by humans.
Dairy products are commonly found in European, Middle Eastern, and Indian cuisine, whereas aside from Mongolian cuisine they are little-known in traditional Asian cuisine.

Section: Optical

Question: Why is the practical magnification limit ~1500x for typical magnification in a light microscope?

The most common type of microscope (and the first invented) is the optical microscope.
This is an optical instrument containing one or more lenses producing an enlarged image of a sample placed in the focal plane.
Optical microscopes have refractive glass and occasionally of plastic or quartz, to focus light into the eye or another light detector.
Mirror-based optical microscopes operate in the same manner.
Typical magnification of a light microscope, assuming visible range light, is up to 1250x with a theoretical resolution limit of around 0.250 micrometres or 250 nanometres.
This limits the practical magnification limit to ~1500x.
Specialized techniques (e.g., scanning confocal microscopy, Vertico SMI) may exceed this magnification but the resolution is diffraction limited.
The use of shorter wavelengths of light, such as the ultraviolet, is one way to improve the spatial resolution of the optical microscope, as are devices such as the near-field scanning optical microscope.
Sarfus, a recent optical technique increases the sensitivity of standard optical microscope to a point it becomes possible to directly visualize nanometric films (down to 0.3 nanometre) and isolated nano-objects (down to 2 nm-diameter).
The technique is based on the use of non-reflecting substrates for cross-polarized reflected light microscopy.
Ultraviolet light enables the resolution of microscopic features, as well as to image samples that are transparent to the eye.
Near infrared light can be used to visualize circuitry embedded in bonded silicon devices, since silicon is transparent in this region of wavelengths.
In fluorescence microscopy, many wavelengths of light, ranging from the ultraviolet to the visible can be used to cause samples to fluoresce to allow viewing by eye or with the use of specifically sensitive cameras.
Phase contrast microscopy is an optical microscopy illumination technique in which small phase shifts in the light passing through a transparent specimen are converted into amplitude or contrast changes in the image.
The use of phase contrast does not require staining to view the slide.
This microscope technique made it possible to study the cell cycle in live cells.
The traditional optical microscope has more recently evolved into the digital microscope.
In addition to, or instead of, directly viewing the object through the eyepieces, a type of sensor similar to those used in a digital camera is used to obtain an image, which is then displayed on a computer monitor.
These sensors may use CMOS or charge-coupled device (CCD) technology, depending on the application.

Section: Motion pictures

Question: Which country produces the world's most-watched cinema?

The Indian film industry produces the world's most-watched cinema.
Established regional cinematic traditions exist in the Assamese, Bengali, Hindi, Kannada, Malayalam, Punjabi, Gujarati, Marathi, Oriya, Tamil, and Telugu languages.
South Indian cinema attracts more than 75% of national film revenue.
Television broadcasting began in India in 1959 as a state-run medium of communication, and had slow expansion for more than two decades.
The state monopoly on television broadcast ended in the 1990s and, since then, satellite channels have increasingly shaped popular culture of Indian society.
Today, television is the most penetrative media in India; industry estimates indicate that as of 2012 there are over 554 million TV consumers, 462 million with satellite and/or cable connections, compared to other forms of mass media such as press (350 million), radio (156 million) or internet (37 million).
Article: British Museum
Section: Collecting from the wider world (1850–75)

Question: At what point did the British museum begin to grow their collection?

Collecting from the wider world (1850–75).
The opening of the forecourt in 1852 marked the completion of Robert Smirke's 1823 plan, but already adjustments were having to be made to cope with the unforeseen growth of the collections.
Infill galleries were constructed for Assyrian sculptures and Sydney Smirke's Round Reading Room, with space for a million books, opened in 1857.
Because of continued pressure on space the decision was taken to move natural history to a new building in South Kensington, which would later become the British Museum of Natural History.
Roughly contemporary with the construction of the new building was the career of a man sometimes called the "second founder" of the British Museum, the Italian librarian Anthony Panizzi.
Under his supervision, the British Museum Library (now the British Library) quintupled in size and became a well-organised institution worthy of being called a national library, the largest library in the world after the National Library of Paris.
The quadrangle at the centre of Smirke's design proved to be a waste of valuable space and was filled at Panizzi's request by a circular Reading Room of cast iron, designed by Smirke's brother, Sydney Smirke.
Until the mid-19th century, the Museum's collections were relatively circumscribed but, in 1851, with the appointment to the staff of Augustus Wollaston Franks to curate the collections, the Museum began for the first time to collect British and European medieval antiquities, prehistory, branching out into Asia and diversifying its holdings of ethnography.
Overseas excavations continued and John Turtle Wood discovered the remains of the 4th century BC Temple of Artemis at Ephesos, another Wonder of the Ancient World.
Article: Mona Lisa
Section: History

Question: Who put the "Mona Lisa" in the Palace of Versailles?

Leonardo da Vinci began painting the "Mona Lisa" in 1503 or 1504 in Florence, Italy.
Although the Louvre states that it was "doubtless painted between 1503 and 1506", the art historian Martin Kemp says there is some difficulty in confirming the actual dates with certainty.
According to Leonardo's contemporary, Giorgio Vasari, "after he had lingered over it four years, left it unfinished".
Leonardo, later in his life, is said to have regretted "never having completed a single work".
In 1516 Leonardo was invited by King François I to work at the Clos Lucé near the king's castle in Amboise.
It is believed that he took the "Mona Lisa" with him and continued to work after he moved to France.
Art historian Carmen C. Bambach has concluded that da Vinci probably continued refining the work until 1516 or 1517.
On his death the painting was inherited, among other works, by his pupil and assistant Salaì.
The king bought the painting for 4,000 "écus" and kept it at Palace of Fontainebleau, where it remained until given to Louis XIV.
Louis XIV moved the painting to the Palace of Versailles.
After the French Revolution, it was moved to the Louvre, but spent a brief period in the bedroom of Napoleon in the Tuileries Palace.
During the Franco-Prussian War (1870–1871) it was moved from the Louvre to the Brest Arsenal.
During World War II, the painting was again removed from the Louvre and taken safely, first to Château d'Amboise, then to the Loc-Dieu Abbey and Château de Chambord, then finally to the Ingres Museum in Montauban.
Article: Have Yourself a Merry Little Christmas
Section: "Meet Me in St. Louis"

Question: Where was the song "Have Yourself a Merry Little Christmas" first used?

The song was written while Martin was vacationing in a house in the neighborhood of Southside in Birmingham, Alabama, that his father Hugh Martin designed for his mother as a honeymoon cottage.
Located at 1919 South 15th Avenue, (just down the street from his birthplace at 1900 South 14th Avenue) the house became the home of Martin and his family in 1923.
The song first appeared in a scene in "Meet Me in St. Louis", in which a family is distraught by the father's plans to move to New York City for a job promotion, leaving behind their beloved home in St. Louis, Missouri, just before the long-anticipated 1904 World's Fair begins.
In a scene set on Christmas Eve, Judy Garland's character, Esther, sings the song to cheer up her despondent five-year-old sister, Tootie, played by Margaret O'Brien.
Article: Great Smoky Mountains National Park
Section: Abstract

Question: What is the most visited national park in the U.S.?

Great Smoky Mountains National Park is a United States National Park and UNESCO World Heritage Site that straddles the ridgeline of the Great Smoky Mountains, part of the Blue Ridge Mountains, which are a division of the larger Appalachian Mountain chain.
The border between Tennessee and North Carolina runs northeast to southwest through the centerline of the park.
It is the most visited national park in the United States.
On its route from Maine to Georgia, the Appalachian Trail also passes through the center of the park.
The park was chartered by the United States Congress in 1934 and officially dedicated by President Franklin Delano Roosevelt in 1940.
It encompasses , making it one of the largest protected areas in the eastern United States.
The main park entrances are located along U.S. Highway 441 (Newfound Gap Road) at the towns of Gatlinburg, Tennessee, and Cherokee, North Carolina.
It was the first national park whose land and other costs were paid for in part with federal funds; previous parks were funded wholly with state money or private funds.

Section: Variants

Question: How do Germans eat croissants?

Uncooked croissant can also be wrapped around any praline, almond paste or chocolate before it is baked (in the last case, it becomes like "pain au chocolat", which has a different, non-crescent, shape), or sliced to admit sweet or savoury fillings.
Indeed, it may be flavoured with dried fruit such as sultanas or raisins, or other fruits such as apples.
In France and Spain, croissants are generally sold without filling and eaten without added butter, but sometimes with almond filling.
In the United States, sweet fillings or toppings are common, and warm croissants may be filled with ham and cheese or feta cheese and spinach.
In the Levant, croissants are sold plain or filled with chocolate, cheese, almonds, or zaatar.
In Germany, croissants are sometimes filled with Nutella or persipan; in Southern Germany there also is a popular variety of a croissant glazed with lye ("Laugencroissant").
In the German-speaking part of Switzerland, the croissant is typically called a "Gipfeli" [g̥ɪp͡fəli], which typically has a crisper crust and is less buttery than the French style croissant.

Question: How many guests did Tokyo Disneyland host in 2009?

There are seven themed areas in the park: the World Bazaar; the four classic Disney lands: Adventureland, Westernland, Fantasyland and Tomorrowland; and two mini-lands: Critter Country and Mickey's Toontown.
Many of the games and rides in these areas mirror those in the original Disneyland as they are based on American Disney films and fantasies.
Fantasyland includes Peter Pan's Flight, Snow White's Scary Adventures, Dumbo the Flying Elephant, and more based on classic Disney films and characters.
The park is noted for its extensive open spaces, to accommodate the large crowds that visit the park.
In 2009, Tokyo Disneyland hosted approximately 13.65 million guests, ranking it as the third-most visited theme park in the world, behind its American sister parks, Magic Kingdom in Orlando and Disneyland Park in Anaheim.
In 2011, the park hosted 14 million visitors, again ranking it as the world's third most visited theme park.
Article: Chemical reaction
Section: Precipitation

Question: What is the chemical reaction of the formation of a solid in a solution?

Precipitation is the formation of a solid in a solution or inside another solid during a chemical reaction.
It usually takes place when the concentration of dissolved ions exceeds the solubility limit and forms an insoluble salt.
This process can be assisted by adding a precipitating agent or by removal of the solvent.
Rapid precipitation results in an amorphous or microcrystalline residue and slow process can yield single crystals.
The latter can also be obtained by recrystallization from microcrystalline salts.
Article: Andy Warhol
Section: Collections

Question: What year did a girl snatch Warhol's wig off?

Warhol was an avid collector.
His friends referred to his numerous collections, which filled not only his four-story townhouse, but also a nearby storage unit, as "Andy's Stuff."
The true extent of his collections was not discovered until after his death, when the Andy Warhol Museum in Pittsburgh took in 641 boxes of his "Stuff.
"Warhol's collections included airplane menus, unpaid invoices, pizza dough, pornographic pulp novels, newspapers, stamps, supermarket flyers, and cookie jars, among other eccentricities.
One of his main collections was his wigs.
Warhol owned over forty and felt very protective of his hairpieces which were sewn by a New York wig-maker from hair imported from Italy.
In 1985 a girl snatched Warhol's wig off his head.
It was later discovered in Warhol's diary entry for that day that he wrote "I don't know what held me back from pushing her over the balcony.
"Another item found in Warhol's boxes at the museum in Pittsburgh was a mummified human foot from Ancient Egypt.
The curator of anthropology at Carnegie Museum of Natural History felt that Warhol most likely found it at a flea market.
Article: Set Fire to the Rain
Section: Composition

Question: What key is "Set Fire to the Rain" written in?

"Set Fire to the Rain" is the fifth track on Adele's second album "21".
It was written with producer Fraser T Smith.
It is written in the key of D minor with a tempo of 108 beats per minute, following the chord progression of Dm–F–C–Gm–Dm–F–C–Csus4–C, and Adele's voice spans A3-D5.
The song describes the contradictory elements of a relationship, and the impossibility of letting go which is displayed in the lyrics "You and me together, nothing gets better/But there’s a side to you that I never knew, never knew/All the things you'd say, they were never true, never true/And the games you play, you would always win."
One of the most pop-influenced of the album, the song is characterised by John Murphy of MusicOMH as a "power ballad".
In contrast to the understated production of most songs on the album, the song features lush instrumentation and a swelling string arrangement over a mid-tempo rhythm, creating a wall of sound for the singer's mourning vocals.
Dave Simpson of "The Guardian" in an article revealed that Adele got inspiration for the song "when mah lightah stopped workin'" in the wet.

Question: How long was Dora Maar Picasso's mistress?

Dora Maar was Picasso's mistress from 1936 until 1944.
In the course of their relationship, Picasso painted her in a number of guises, some realistic, some benign, others tortured or threatening.
Picasso explained:""For me she's the weeping woman.
For years I've painted her in tortured forms, not through sadism, and not with pleasure, either; just obeying a vision that forced itself on me.
It was the deep reality, not the superficial one.
""""Dora, for me, was always a weeping woman... And it's important, because women are suffering machines.""

Article: The Matrix
Section: Development

Question: When the Wachowskis presented their script for Assasins, what production studio were they at?

In 1994, the Wachowskis presented the script for the film "Assassins" to Warner Brothers.
After Lorenzo di Bonaventura, the president of production of the company at the time, read the script, he decided to buy rights to it and included two more pictures, "Bound" and "The Matrix", in the contract.
The first movie the Wachowskis directed, "Bound", then became a critical success.
Using this momentum, the brothers later asked to direct "The Matrix".
Producer Joel Silver soon joined the project.
Although the project had key supporters like Silver and Di Bonaventura to influence the company, "The Matrix" was still a huge investment for Warner Bros, which had to invest $60 million to create a movie with deep philosophical ideas and difficult special effects.
The Wachowskis therefore hired underground comic book artists Geof Darrow and Steve Skroce to draw a 600-page, shot-by-shot storyboard for the entire film.
The storyboard eventually earned the studio's approval, and it was decided to film in Australia to make the most of the budget.
Soon, "The Matrix" became a co-production of Warner Bros. and the Australian company Village Roadshow Pictures.
Article: Bacteria
Section: Bacteriophages

Question: What are bacteriophages?

Bacteriophages are viruses that infect bacteria.
Many types of bacteriophage exist, some simply infect and lyse their host bacteria, while others insert into the bacterial chromosome.
A bacteriophage can contain genes that contribute to its host's phenotype: for example, in the evolution of and "Clostridium botulinum", the toxin genes in an integrated phage converted a harmless ancestral bacterium into a lethal pathogen.
Bacteria resist phage infection through restriction modification systems that degrade foreign DNA, and a system that uses CRISPR sequences to retain fragments of the genomes of phage that the bacteria have come into contact with in the past, which allows them to block virus replication through a form of RNA interference.
This CRISPR system provides bacteria with acquired immunity to infection.
