Rasmus Bartholin is remembered especially for his discovery (1669) of the double refraction of a light ray by Iceland spar (calcite). He published an accurate description of the phenomenon, but since the physical nature of light was poorly understood at the time, he was unable to explain it. It was only after Thomas Young proposed the wave theory of light, c. 1801 that an explanation became possible.

Question: Why was Rasmus unable to explain the phenomenon?
Answer: physical nature of light was poorly understood at the time

Torpedo bombers first appeared immediately prior to the First World War. Generally, they carried torpedoes specifically designed for air launch, which were smaller and lighter than those used by submarines and surface warships. Nonetheless, as an airborne torpedo could weigh as much as 2,000 pounds (910 kg), more than twice the bomb load of contemporary single-engined bombers, the aircraft carrying it usually needed to be specially designed for the purpose. Many early torpedo bombers were floatplanes, such as the Short 184 (the first aircraft to sink a ship with a torpedo), and the undercarriage had to be redesigned so that the torpedo could be dropped from the aircraft's centerline.

Question: Airborne torpedos are not capable of being carried by what?
Answer: contemporary single-engined bombers

An accompanying music video, directed by Nigel Dick, portrays Spears as a student from a Catholic high school, who starts to daydream that she is singing and dancing around the school, while watching her love interest from afar. The music video was later referenced in the music video of "If U Seek Amy" (2009), where Spears's fictional daughter is dressed with a similar schoolgirl outfit while wearing pink ribbons in her hair. In 2010, the music video for "...Baby One More Time" was voted the third most influential video in the history of pop music, in a poll held by Jam!. In 2011, "...Baby One More Time" was voted by Billboard to be the best music video of the 1990s. It has been featured on all of her greatest hits and other compilation albums.

Question: Who directed Spears in her music video Baby One More Time?

Messier 83 or M83, also known as the Southern Pinwheel Galaxy and NGC 5236, is a barred spiral galaxy approximately 15 million light-years away in the constellation Hydra. Nicolas Louis de Lacaille discovered M83 on February 23, 1752 at the Cape of Good Hope. Charles Messier added it to his catalogue of nebulous objects (now known as the Messier Catalogue) in March 1781. This is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars. Its nickname of the Southern Pinwheel derives from its resemblance to the Pinwheel Galaxy (M101).

Question: What was added to Charles Messier's catalogue of nebulous objects in 1781?
Answer: Messier 83 or M83
One of the most controversial issues examined by the inquiries was the role played by SS Californian, which had been only a few miles from Titanic but had not picked up her distress calls or responded to her signal rockets. Californian had warned Titanic by radio of the pack ice (that was the reason Californian had stopped for the night) but was rebuked by Titanic's senior wireless operator, Jack Phillips.Testimony before the British inquiry revealed that at 10:10 p.m., Californian observed the lights of a ship to the south; it was later agreed between Captain Stanley Lord and Third Officer C.V. Groves (who had relieved Lord of duty at 11:10 p.m.) that this was a passenger liner. At 11:50 p.m., the officer had watched that ship's lights flash out, as if she had shut down or turned sharply, and that the port light was now visible. Morse light signals to the ship, upon Lord's order, were made between 11:30 p.m. and 1:00 a.m., but were not acknowledged. If Titanic was as far from the Californian as Lord claimed, then he knew, or should have known, that Morse signals would not be visible. A reasonable and prudent course of action would have been to awaken the wireless operator and to instruct him to attempt to contact Titanic by that method. Had Lord done so, it is possible he could have reached Titanic in time to save additional lives.Captain Lord had gone to the chartroom at 11:00 p.m. to spend the night; however, Second Officer Herbert Stone, now on duty, notified Lord at 1:10 a.m. that the ship had fired five rockets. Lord wanted to know if they were company signals, that is, coloured flares used for identification. Stone said that he did not know and that the rockets were all white. Captain Lord instructed the crew to continue to signal the other vessel with the Morse lamp, and went back to sleep. Three more rockets were observed at 1:50 a.m. and Stone noted that the ship looked strange in the water, as if she were listing. At 2:15 a.m., Lord was notified that the ship could no longer be seen. Lord asked again if the lights had had any colours in them, and he was informed that they were all white.Californian eventually responded. At around 5:30 a.m., Chief Officer George Stewart awakened wireless operator Cyril Furmstone Evans, informed him that rockets had been seen during the night, and asked that he try to communicate with any ship. He got news of Titanic's loss, Captain Lord was notified, and the ship set out to render assistance. She arrived well after Carpathia had already picked up all the survivors.The inquiries found that the ship seen by Californian was in fact Titanic and that it would have been possible for Californian to come to her rescue; therefore, Captain Lord had acted improperly in failing to do so.

Question: Why did the Chef Officer wanted to seek other ships?
Answer: rockets had been seen during the night
As minors by law, children do not have autonomy or the right to make decisions on their own for themselves in any known jurisdiction of the world. Instead their adult caregivers, including parents, social workers, teachers, youth workers, and others, are vested with that authority, depending on the circumstances. Some believe that this state of affairs gives children insufficient control over their own lives and causes them to be vulnerable. Louis Althusser has gone so far as to describe this legal machinery, as it applies to children, as "repressive state apparatuses".Structures such as government policy have been held by some commentators to mask the ways adults abuse and exploit children, resulting in child poverty, lack of educational opportunities, and child labour. On this view, children are to be regarded as a minority group towards whom society needs to reconsider the way it behaves.Researchers have identified children as needing to be recognized as participants in society whose rights and responsibilities need to be recognized at all ages.

Question: How much control do the children have ?
Answer: insufficient control

The earliest paintings found on the Korean peninsula are petroglyphs of prehistoric times. With the arrival of Buddhism from India via China, different techniques were introduced. These techniques quickly established themselves as the mainstream techniques, but indigenous techniques still survived. Among them were the Goguryeo tomb murals. These murals inside many of the tombs are an invaluable insight into the ceremonies, warfare, architecture, and daily life of ancient Goguryeo people. Balhae kingdom, an successor state of Goguryeo, absorbed much of traditional Goguryeo elements.There is a tendency towards naturalism with subjects such as realistic landscapes, flowers and birds being particularly popular. Ink is the most common material used, and it is painted on mulberry paper or silk.

Jon Bon Jovi began playing music in 1975, at the age of 13, playing piano and guitar with his first band, Raze. At 16, Jon met David Bryan and formed a band called Atlantic City Expressway. Still in his teens, Bon Jovi played in the band John Bongiovi and the Wild Ones, playing clubs such as the Fast Lane and opening for local acts. By 1980, he had formed another band, the Rest, and opened up for New Jersey acts such as Southside Johnny and the Asbury Jukes. Also in 1980, Jon recorded his first single, "Runaway" in his cousin's studio, backed up by studio musicians. The song was played by a local radio station on a compilation tape.By mid-1982, out of school and working part-time at a women's shoe store, Jon Bon Jovi took a job at the Power Station Studios, a Manhattan recording facility where his cousin Tony Bongiovi was co-owner. Jon made several demos—including one produced by Billy Squier—and sent them to record companies, though failing to make an impact. His first professional recording was as lead vocals in "R2-D2 We Wish You a Merry Christmas," which was part of the Christmas in the Stars album which his cousin co-produced.In 1983, Jon visited a local radio station WAPP 103.5FM "The Apple" in Lake Success, New York to write and sing the jingles for the station. He spoke with DJ Chip Hobart and to the promotion director, John Lassman, who suggested Jon let WAPP include the song "Runaway" on the station's compilation album of local homegrown talent. Jon was reluctant, but eventually gave them the song, which he had rerecorded in 1982 (following a rough early recording in 1981) with local studio musicians whom he designated The All Star Review—guitarist Tim Pierce, keyboardist Roy Bittan, drummer Frankie LaRocka, and bassist Hugh McDonald.

The song began to get airplay in the New York area, then other sister stations in major markets picked up the song. In March 1983, Bon Jovi called David Bryan, who in turn called bassist Alec John Such and an experienced drummer named Tico Torres, both formerly of the band Phantom's Opera.

The Arecibo message is a 1974 interstellar radio message carrying basic information about humanity and Earth sent to globular star cluster M13 in the hope that extraterrestrial intelligence might receive and decipher it. The message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope in Puerto Rico on 16 November 1974. The message was aimed at the current location of M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony. The message consisted of 1,679 binary digits, approximately 210 bytes, transmitted at a frequency of 2,380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 450 kW. The "ones" and "zeros" were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes.The number 1,679 was chosen because it is a semiprime (the product of two prime numbers), to be arranged rectangularly as 73 rows by 23 columns. The alternative arrangement, 23 rows by 73 columns, produces an unintelligible set of characters (as do all other X/Y formats). The message forms the image shown here when translated into graphics, characters, and spaces.Dr. Frank Drake, then at Cornell University and creator of the Drake equation, wrote the message with help from Carl Sagan, among others. The message consists of seven parts that encode the following (from the top down):

Question: How many sections of the message are there?
Answer: seven parts

Question: In what year was the Arecibo message created?
Answer: 1974

Wild Chrysanthemum taxa are herbaceous perennial plants or subshrubs. They have alternately arranged leaves divided into leaflets with toothed or occasionally smooth edges. The compound inflorescence is an array of several flower heads, or sometimes a solitary head. The head has a base covered in layers of phyllaries. The simple row of ray florets is white, yellow, or red; many horticultural specimens have been bred to bear many rows of ray florets in a great variety of colors. The disc florets of wild taxa are yellow. The fruit is a ribbed achene. Chrysanthemums, also known as "mums", are one of the prettiest varieties of perennials that start blooming early in the autumn. This is also known as favorite flower for the month of November.

Question: What is a ray florets?
Answer: a ribbed achene
