Answer: a storm

Context: In April 1191 Richard the Lion-hearted left Messina with a large fleet in order to reach Acre. But a storm dispersed the fleet. After some searching, it was discovered that the boat carrying his sister and his fiancée Berengaria was anchored on the south coast of Cyprus, together with the wrecks of several other ships, including the treasure ship. Survivors of the wrecks had been taken prisoner by the island's despot Isaac Komnenos. On 1 May 1191, Richard's fleet arrived in the port of Limassol on Cyprus. He ordered Isaac to release the prisoners and the treasure. Isaac refused, so Richard landed his troops and took Limassol.

The local barons abandoned Isaac, who considered making peace with Richard, joining him on the crusade, and offering his daughter in marriage to the person named by Richard. But Isaac changed his mind and tried to escape. Richard then proceeded to conquer the whole island, his troops being led by Guy de Lusignan. Isaac surrendered and was confined with silver chains, because Richard had promised that he would not place him in irons. By 1 June, Richard had conquered the whole island. His exploit was well publicized and contributed to his reputation; he also derived significant financial gains from the conquest of the island. Richard left for Acre on 5 June, with his allies. Before his departure, he named two of his Norman generals, Richard de Camville and Robert de Thornham, as governors of Cyprus.

Answer: 1489

Context: The rapid Anglo-Norman conquest proved more important than it seemed. The island occupied a key strategic position on the maritime lanes to the Holy Land, whose occupation by the Christians could not continue without support from the sea. Shortly after the conquest, Cyprus was sold to the Knights Templar and it was subsequently acquired, in 1192, by Guy de Lusignan and became a stable feudal kingdom. It was only in 1489 that the Venetians acquired full control of the island, which remained a Christian stronghold until the fall of Famagusta in 1571.

Context: The customary law of Normandy was developed between the 10th and 13th centuries and survives today through the legal systems of Jersey and Guernsey in the Channel Islands. Norman customary law was transcribed in two customaries in Latin by two judges for use by them and their colleagues: These are the Très ancien coutumier (Very ancient customary), authored between 1200 and 1245; and the Grand coutumier de Normandie (Great customary of Normandy, originally Summa de legibus Normanniae in curia laïcali), authored between 1235 and 1245.

Question: Where are Jersey and Guernsey


Answer: two

Question: How many customaries does Norman customary law have?


Answer: Romanesque

Context: Norman architecture typically stands out as a new stage in the architectural history of the regions they subdued. They spread a unique Romanesque idiom to England and Italy, and the encastellation of these regions with keeps in their north French style fundamentally altered the military landscape. Their style was characterised by rounded arches, particularly over windows and doorways, and massive proportions.

Question: What is the Norman architecture idiom?


Answer: rounded

Question: What kind of arches does Norman architecture have?


Answer: Early Gothic

Context: In England, the period of Norman architecture immediately succeeds that of the Anglo-Saxon and precedes the Early Gothic. In southern Italy, the Normans incorporated elements of Islamic, Lombard, and Byzantine building techniques into their own, initiating a unique style known as Norman-Arab architecture within the Kingdom of Sicily.

Question: What architecture type came after Norman in England?


Answer: Anglo-Saxon

Question: What architecture type came before Norman in England?


Answer: Sicily

Question: What place had the Norman Arab architectural style?


Answer: early 11th century

Context: In the visual arts, the Normans did not have the rich and distinctive traditions of the cultures they conquered. However, in the early 11th century the dukes began a programme of church reform, encouraging the Cluniac reform of monasteries and patronising intellectual pursuits, especially the proliferation of scriptoria and the reconstitution of a compilation of lost illuminated manuscripts. The church was utilised by the dukes as a unifying force for their disparate duchy. The chief monasteries taking part in this "renaissance" of Norman art and scholarship were Mont-Saint-Michel, Fécamp, Jumièges, Bec, Saint-Ouen, Saint-Evroul, and Saint-Wandrille. These centres were in contact with the so-called "Winchester school", which channeled a pure Carolingian artistic tradition to Normandy. In the final decade of the 11th and first of the 12th century, Normandy experienced a golden age of illustrated manuscripts, but it was brief and the major scriptoria of Normandy ceased to function after the midpoint of the century.

Question: When did the church reform begin?


Answer: dukes

Question: Who used the church to unify themselves?


Answer: 16th century

Context: The French Wars of Religion in the 16th century and French Revolution in the 18th successively destroyed much of what existed in the way of the architectural and artistic remnant of this Norman creativity. The former, with their violence, caused the wanton destruction of many Norman edifices; the latter, with its assault on religion, caused the purposeful destruction of religious objects of any type, and its destabilisation of society resulted in rampant pillaging.

Question: When were the French wars of religion?


Answer: embroidery

Context: By far the most famous work of Norman art is the Bayeux Tapestry, which is not a tapestry but a work of embroidery. It was commissioned by Odo, the Bishop of Bayeux and first Earl of Kent, employing natives from Kent who were learned in the Nordic traditions imported in the previous half century by the Danish Vikings.

Question: What kind of needlework was used in the creation of the Bayeux Tapestry?


Answer: Bayeux Tapestry

Question: What is Norman art's most well known piece?


Answer: Odo

Question: Who commissioned the Tapestry?


Answer: mosaics

Context: In Britain, Norman art primarily survives as stonework or metalwork, such as capitals and baptismal fonts. In southern Italy, however, Norman artwork survives plentifully in forms strongly influenced by its Greek, Lombard, and Arab forebears. Of the royal regalia preserved in Palermo, the crown is Byzantine in style and the coronation cloak is of Arab craftsmanship with Arabic inscriptions. Many churches preserve sculptured fonts, capitals, and more importantly mosaics, which were common in Norman Italy and drew heavily on the Greek heritage. Lombard Salerno was a centre of ivorywork in the 11th century and this continued under Norman domination. Finally should be noted the intercourse between French Crusaders traveling to the Holy Land who brought with them French artefacts with which to gift the churches at which they stopped in southern Italy amongst their Norman cousins. For this reason many south Italian churches preserve works from France alongside their native pieces.

Question: What is the most important type of Norman art preserved in churches?


Answer: 11th

Context: Normandy was the site of several important developments in the history of classical music in the 11th century. Fécamp Abbey and Saint-Evroul Abbey were centres of musical production and education. At Fécamp, under two Italian abbots, William of Volpiano and John of Ravenna, the system of denoting notes by letters was developed and taught. It is still the most common form of pitch representation in English- and German-speaking countries today. Also at Fécamp, the staff, around which neumes were oriented, was first developed and taught in the 11th century. Under the German abbot Isembard, La Trinité-du-Mont became a centre of musical composition.

Question: In what century did important classical music developments occur in Normandy?


Answer: William of Volpiano and John of Ravenna

Question: Who were the two abbots at Fécamp Abbey?

Context: In 1875, Tesla enrolled at Austrian Polytechnic in Graz, Austria, on a Military Frontier scholarship. During his first year, Tesla never missed a lecture, earned the highest grades possible, passed nine exams (nearly twice as many required), started a Serbian culture club, and even received a letter of commendation from the dean of the technical faculty to his father, which stated, "Your son is a star of first rank." Tesla claimed that he worked from 3 a.m. to 11 p.m., no Sundays or holidays excepted. He was "mortified when [his] father made light of [those] hard won honors." After his father's death in 1879, Tesla found a package of letters from his professors to his father, warning that unless he were removed from the school, Tesla would be killed through overwork. During his second year, Tesla came into conflict with Professor Poeschl over the Gramme dynamo, when Tesla suggested that commutators weren't necessary. At the end of his second year, Tesla lost his scholarship and became addicted to gambling. During his third year, Tesla gambled away his allowance and his tuition money, later gambling back his initial losses and returning the balance to his family. Tesla said that he "conquered [his] passion then and there," but later he was known to play billiards in the US. When exam time came, Tesla was unprepared and asked for an extension to study, but was denied. He never graduated from the university and did not receive grades for the last semester.

Context: The investors showed little interest in Tesla's ideas for new types of motors and electrical transmission equipment and also seemed to think it was better to develop an electrical utility than invent new systems. They eventually forced Tesla out leaving him penniless. He even lost control of the patents he had generated since he had assigned them to the company in lieu of stock. He had to work at various electrical repair jobs and even as a ditch digger for $2 per day. Tesla considered the winter of 1886/1887 as a time of "terrible headaches and bitter tears." During this time, he questioned the value of his education.

Answer: a Western Union superintendent

Context: In late 1886 Tesla met Alfred S. Brown, a Western Union superintendent, and New York attorney Charles F. Peck. The two men were experienced in setting up companies and promoting inventions and patents for financial gain. Based on Tesla's patents and other ideas they agreed to back him financially and handle his patents. Together in April 1887 they formed the Tesla Electric Company with an agreement that profits from generated patents would go ⅓ to Tesla, ⅓ to Peck and Brown, and ⅓ to fund development. They set up a laboratory for Tesla at 89 Liberty Street in Manhattan where he worked on improving and developing new types of electric motors, generators and other devices.

Answer: an induction motor

Context: One of the things Tesla developed at that laboratory in 1887 was an induction motor that ran on alternating current, a power system format that was starting to be built in Europe and the United States because of its advantages in long-distance, high-voltage transmission. The motor used polyphase current which generated a rotating magnetic field to turn the motor (a principle Tesla claimed to have conceived in 1882). This innovative electric motor, patented in May 1888, was a simple self-starting design that did not need a commutator, thus avoiding sparking and the high maintenance of constantly servicing and replacing mechanical brushes.

Answer: editor of Electrical World magazine

Context: In 1888, the editor of Electrical World magazine, Thomas Commerford Martin (a friend and publicist), arranged for Tesla to demonstrate his alternating current system, including his induction motor, at the American Institute of Electrical Engineers (now IEEE). Engineers working for the Westinghouse Electric & Manufacturing Company reported to George Westinghouse that Tesla had a viable AC motor and related power system — something for which Westinghouse had been trying to secure patents. Westinghouse looked into getting a patent on a similar commutator-less, rotating magnetic field-based induction motor presented in a paper in March 1888 by the Italian physicist Galileo Ferraris, but decided Tesla's patent would probably control the market.

Question: In which city was Tesla's consultant job for Westinghouse?


Answer: Pittsburgh

Context: During that year, Tesla worked in Pittsburgh, helping to create an alternating current system to power the city's streetcars. He found the time there frustrating because of conflicts between him and the other Westinghouse engineers over how best to implement AC power. Between them, they settled on a 60-cycle AC current system Tesla proposed (to match the working frequency of Tesla's motor), although they soon found that, since Tesla's induction motor could only run at a constant speed, it would not work for street cars. They ended up using a DC traction motor instead.

Answer: Thomas Edison and George Westinghouse

Context: Tesla's demonstration of his induction motor and Westinghouse's subsequent licensing of the patent, both in 1888, put Tesla firmly on the "AC" side of the so-called "War of Currents," an electrical distribution battle being waged between Thomas Edison and George Westinghouse that had been simmering since Westinghouse's first AC system in 1886 and had reached the point of all-out warfare by 1888. This started out as a competition between rival lighting systems with Edison holding all the patents for DC and the incandescent light and Westinghouse using his own patented AC system to power arc lights as well as incandescent lamps of a slightly different design to get around the Edison patent. The acquisition of a feasible AC motor gave Westinghouse a key patent in building a completely integrated AC system, but the financial strain of buying up patents and hiring the engineers needed to build it meant development of Tesla's motor had to be put on hold for a while. The competition resulted in Edison Machine Works pursuing AC development in 1890 and by 1892 Thomas Edison was no longer in control of his own company, which was consolidated into the conglomerate General Electric and converting to an AC delivery system at that point.

Answer: George Westinghouse

Context: In 1893, George Westinghouse won the bid to light the 1893 World's Columbian Exposition in Chicago with alternating current, beating out a General Electric bid by one million dollars. This World's Fair devoted a building to electrical exhibits. It was a key event in the history of AC power, as Westinghouse demonstrated the safety, reliability, and efficiency of a fully integrated alternating current system to the American public. At the Columbian Exposition, under a banner announcing the "Tesla Polyphase System", Tesla demonstrated a series of electrical effects previously performed throughout America and Europe,:76 included using high-voltage, high-frequency alternating current to light a wireless gas-discharge lamp.:79 An observer noted:

Answer: Richard Dean Adams

Context: In 1893 Richard Dean Adams, who headed up the Niagara Falls Cataract Construction Company sought Tesla's opinion on what system would be best to transmit power generated at the falls. Over several years there had been a series of proposals and open competitions on how best to utilize power generated by the falls with many systems being proposed by several US and European companies including two-phase and three-phase AC, high-voltage DC, and even compressed air. Adams pumped Tesla for information about the current state of all the competing systems. Tesla advised Adams that a two-phased system would be the most reliable and that there was a Westinghouse system to light incandescent bulbs using two-phase alternating current. Based on Tesla's advice and Westinghouse's demonstration that they could build a complete AC system at the Columbian Exposition, a contract for building a two-phase AC generating system at the Niagara Falls was awarded to Westinghouse Electric. A further contract to build the AC distribution system was awarded to General Electric.

Answer: 1896

Context: The mid 1890s saw the conglomerate General Electric, backed by financier J. P. Morgan, involved in takeover attempts and patent battles with Westinghouse Electric. Although a patent-sharing agreement was signed between the two companies in 1896 Westinghouse was still cash-strapped from the financial warfare. To secure further loans, Westinghouse was forced to revisit Tesla's AC patent, which bankers considered a financial strain on the company (at that point Westinghouse had paid out an estimated $200,000 in licenses and royalties to Tesla, Brown, and Peck). In 1897, Westinghouse explained his financial difficulties to Tesla in stark terms, saying that if things continue the way they were he would no longer be in control of Westinghouse Electric and Tesla would have to "deal with the bankers" to try to collect future royalties. Westinghouse convinced Tesla to release his company from the licensing agreement over Tesla's AC patents in exchange for Westinghouse Electric purchasing the patents for a lump sum payment of $216,000; this provided Westinghouse a break from what, due to alternating current's rapid gain in popularity, had turned out to be an overly generous $2.50 per AC horsepower royalty.

Answer: he had noticed damaged film in his laboratory in previous experiments

Context: Starting in 1894, Tesla began investigating what he referred to as radiant energy of "invisible" kinds after he had noticed damaged film in his laboratory in previous experiments (later identified as "Roentgen rays" or "X-Rays"). His early experiments were with Crookes tubes, a cold cathode electrical discharge tube. Soon after, much of Tesla's early research—hundreds of invention models, plans, notes, laboratory data, tools, photographs, valued at $50,000—was lost in the 5th Avenue laboratory fire of March 1895. Tesla is quoted by The New York Times as saying, "I am in too much grief to talk. What can I say?" Tesla may have inadvertently captured an X-ray image—predating, by a few weeks, Wilhelm Röntgen's December 1895 announcement of the discovery of x-rays—when he tried to photograph Mark Twain illuminated by a Geissler tube, an earlier type of gas discharge tube. The only thing captured in the image was the metal locking screw on the camera lens.:134

Question: What type of image was Tesla thought to have accidentally taken a week prior to the announcement of its discovery?


Answer: Mark Twain

Question: Who was Tesla trying to photograph when he accidentally took the X-Ray image?


Answer: X-ray imaging

Context: In March 1896, after hearing of Wilhelm Röntgen's discovery of X-ray and X-ray imaging (radiography), Tesla proceeded to do his own experiments in X-ray imaging, developing a high energy single terminal vacuum tube of his own design that had no target electrode and that worked from the output of the Tesla Coil (the modern term for the phenomenon produced by this device is bremsstrahlung or braking radiation). In his research, Tesla devised several experimental setups to produce X-rays. Tesla held that, with his circuits, the "instrument will ... enable one to generate Roentgen rays of much greater power than obtainable with ordinary apparatus."

Question: What powered Tesla's high energy terminal vacuum tube?


Answer: Roentgen rays

Question: What were X-rays known as at the time?


Answer: X-rays were longitudinal waves

Context: Tesla noted the hazards of working with his circuit and single-node X-ray-producing devices. In his many notes on the early investigation of this phenomenon, he attributed the skin damage to various causes. He believed early on that damage to the skin was not caused by the Roentgen rays, but by the ozone generated in contact with the skin, and to a lesser extent, by nitrous acid. Tesla incorrectly believed that X-rays were longitudinal waves, such as those produced in waves in plasmas. These plasma waves can occur in force-free magnetic fields.

Answer: 1934

Context: On 11 July 1934, the New York Herald Tribune published an article on Tesla, in which he recalled an event that would occasionally take place while experimenting with his single-electrode vacuum tubes; a minute particle would break off the cathode, pass out of the tube, and physically strike him. "Tesla said he could feel a sharp stinging pain where it entered his body, and again at the place where it passed out." In comparing these particles with the bits of metal projected by his "electric gun," Tesla said, "The particles in the beam of force ... will travel much faster than such particles ... and they will travel in concentrations."

Question: When did the Herald Tribune publish its Tesla article?


Answer: physically strike him

Question: Which of Tesla's inventions was used in radio development?


Answer: the Franklin Institute

Question: What Philadelphia institution did Tesla give a demonstration to?


Answer: 1898

Context: In 1898, Tesla demonstrated a radio-controlled boat—which he dubbed "teleautomaton"—to the public during an electrical exhibition at Madison Square Garden. The crowd that witnessed the demonstration made outrageous claims about the workings of the boat, such as magic, telepathy, and being piloted by a trained monkey hidden inside. Tesla tried to sell his idea to the U.S. military as a type of radio-controlled torpedo, but they showed little interest. Remote radio control remained a novelty until World War I and afterward, when a number of countries used it in military programs. Tesla took the opportunity to further demonstrate "Teleautomatics" in an address to a meeting of the Commercial Club in Chicago, while he was travelling to Colorado Springs, on 13 May 1899.

Answer: 1900

Context: In 1900, Tesla was granted patents for a "system of transmitting electrical energy" and "an electrical transmitter." When Guglielmo Marconi made his famous first-ever transatlantic radio transmission in 1901, Tesla quipped that it was done with 17 Tesla patents, though there is little to support this claim. This was the beginning of years of patent battles over radio with Tesla's patents being upheld in 1903, followed by a reverse decision in favor of Marconi in 1904. In 1943, a Supreme Court of the United States decision restored the prior patents of Tesla, Oliver Lodge, and John Stone. The court declared that their decision had no bearing on Marconi's claim as the first to achieve radio transmission, just that since Marconi's claim to certain patents were questionable, he could not claim infringement on those same patents (there are claims the high court was trying to nullify a World War I claim against the U.S. government by the Marconi Company via simply restoring Tesla's prior patent).

Question: When did Tesla attain his electrical transmitter patent?


Answer: Marconi

Question: Who first sent radio waves across the Atlantic?

Answer: 1899

Context: On 17 May 1899, Tesla moved to Colorado Springs, where he would have room for his high-voltage, high-frequency experiments; his lab was located near Foote Ave. and Kiowa St. He chose this location because the polyphase alternating current power distribution system had been introduced there and he had associates who were willing to give him all the power he needed without charging for it. Upon his arrival, he told reporters that he was conducting wireless telegraphy experiments, transmitting signals from Pikes Peak to Paris.[citation needed] The 1978 book Colorado Springs Notes, 1899–1900 contains descriptions of Tesla's experiments. On 15 June 1899, Tesla performed his first experiments at his Colorado Springs lab; he recorded his initial spark length at five inches long, but very thick and noisy.

Question: In what year did Tesla go to Colorado Springs?


Answer: Paris

Question: Where did he claim he would transport energy to?


Answer: 15 June 1899

Question: What date did Tesla begin his Colorado Springs experiments?


Answer: five inches

Question: What was the recorded length of the first spark?


Answer: atmospheric

Context: Tesla investigated atmospheric electricity, observing lightning signals via his receivers. He stated that he observed stationary waves during this time. The great distances and the nature of what Tesla was detecting from lightning storms confirmed his belief that the earth had a resonant frequency.

Question: What kind of electricity was Tesla investigating?


Answer: stationary

Question: What sort of waves did he claim to observe?


Answer: that the earth had a resonant frequency.

Question: What was Tesla's idea regarding Earth?


Answer: lightning

Context: He produced artificial lightning, with discharges consisting of millions of volts and up to 135 feet long. Thunder from the released energy was heard 15 miles away in Cripple Creek, Colorado. People walking along the street observed sparks jumping between their feet and the ground. Sparks sprang from water line taps when touched. Light bulbs within 100 feet of the lab glowed even when turned off. Horses in a livery stable bolted from their stalls after receiving shocks through their metal shoes. Butterflies were electrified, swirling in circles with blue halos of St. Elmo's fire around their wings.

Answer: 15 miles

Question: From what distance could the artificial thunder be heard.


Answer: glowed even when turned off

Question: What happened to nearby light bulbs?


Answer: Butterflies were electrified

Question: What was notable about the butterflies?


Answer: power outage

Context: While experimenting, Tesla inadvertently faulted a power station generator, causing a power outage. In August 1917, Tesla explained what had happened in The Electrical Experimenter: "As an example of what has been done with several hundred kilowatts of high frequency energy liberated, it was found that the dynamos in a power house six miles away were repeatedly burned out, due to the powerful high frequency currents set up in them, and which caused heavy sparks to jump through the windings and destroy the insulation!"

Question: What did Tesla accidentally cause?


Answer: repeatedly burned out

Question: What happened to the dynamos in the power station?


Answer: powerful high frequency currents

Question: What caused the dynamos to be burnt out?


Answer: destroy

Question: What did the sparks do to the insulation?


Answer: communications from another planet

Context: During his time at his lab, Tesla observed unusual signals from his receiver which he concluded may be communications from another planet. He mentioned them in a letter to reporter Julian Hawthorne at the Philadelphia North American on 8 December 1899 and in a December 1900 letter about possible discoveries in the new century to the Red Cross Society where he referred to messages "from another world" that read "1... 2... 3...". Reporters treated it as a sensational story and jumped to the conclusion Tesla was hearing signals from Mars. He expanded on the signals he heard in a 9 February 1901 Collier's Weekly article "Talking With Planets" where he said it had not been immediately apparent to him that he was hearing "intelligently controlled signals" and that the signals could come from Mars, Venus, or other planets. It has been hypothesized that he may have intercepted Marconi's European experiments in July 1899—Marconi may have transmitted the letter S (dot/dot/dot) in a naval demonstration, the same three impulses that Tesla hinted at hearing in Colorado—or signals from another experimenter in wireless transmission.

Question: To what did Tesla attribute the unknown signals his radio received?


Answer: Mars

Question: What planet did the reporters decide the signals were from?


Answer: Collier's Weekly

Question: What magazine did Tesla talk to about the strange signals?

Question: What kind of facility was Wardenclyffe?


Answer: near Shoreham, Long Island

Question: Where was Wardenclyffe located?


Answer: Morgan

Context: Tesla later approached Morgan to ask for more funds to build a more powerful transmitter. When asked where all the money had gone, Tesla responded by saying that he was affected by the Panic of 1901, which he (Morgan) had caused. Morgan was shocked by the reminder of his part in the stock market crash and by Tesla's breach of contract by asking for more funds. Tesla wrote another plea to Morgan, but it was also fruitless. Morgan still owed Tesla money on the original agreement, and Tesla had been facing foreclosure even before construction of the tower began.

Question: Who did Tesla try to get money from?


Answer: Panic of 1901

Question: On what did Tesla blame for the loss of the initial money?


Answer: shocked

Question: How did Morgan react to the request?


Answer: over 50 letters

Context: In December 1901, Marconi successfully transmitted the letter S from England to Newfoundland, terminating Tesla's relationship with Morgan.[improper synthesis?] Over the next five years, Tesla wrote over 50 letters to Morgan, pleading for and demanding additional funding to complete the construction of Wardenclyffe. Tesla continued the project for another nine months. The tower was erected to its full 187 feet (57 m). In July 1903, Tesla wrote to Morgan that in addition to wireless communication, Wardenclyffe would be capable of wireless transmission of electric power. On 14 October 1904, Morgan finally replied through his secretary, stating, "It will be impossible for [me] to do anything in the matter," after Tesla had written to Morgan when the financier was meeting with the Archbishop of Canterbury in an attempt to appeal to his Christian spirit.

Question: How much correspondence did Tesla send Morgan in the five years following 1901?


Answer: to complete the construction of Wardenclyffe.

Question: Why did Tesla want funds from Morgan?


Answer: Marconi successfully transmitted the letter S from England to Newfoundland

Question: What happened in 1901?


Answer: 187 feet

Question: How tall was the tower's ultimate height?


Answer: 200

Context: On his 50th birthday in 1906, Tesla demonstrated his 200 horsepower (150 kilowatts) 16,000 rpm bladeless turbine. During 1910–1911 at the Waterside Power Station in New York, several of his bladeless turbine engines were tested at 100–5,000 hp.

Question: How many horsepower did Tesla's bladeless turbine have?


Answer: 16,000 rpm

Question: At what speed did the turbine operate?


Answer: 1906

Question: When did Tesla first show off the turbine?


Answer: 100–5,000 hp

Question: What was the horsepower put out by the turbines in Waterside Power Station


Answer: steam

Context: Tesla invented a steam-powered mechanical oscillator—Tesla's oscillator. While experimenting with mechanical oscillators at his Houston Street lab, Tesla allegedly generated a resonance of several buildings. As the speed grew, it is said that the machine oscillated at the resonance frequency of his own building and, belatedly realizing the danger, he was forced to use a sledge hammer to terminate the experiment, just as the police arrived.:162–164 In February 1912, an article—"Nikola Tesla, Dreamer" by Allan L. Benson—was published in World Today, in which an artist's illustration appears showing the entire earth cracking in half with the caption, "Tesla claims that in a few weeks he could set the earth's crust into such a state of vibration that it would rise and fall hundreds of feet and practically destroy civilization. A continuation of this process would, he says, eventually split the earth in two."

Question: How was Tesla's mechanical oscillator powered?


Answer: Houston Street lab

Question: Where did he work on the oscillators?


Answer: the machine oscillated at the resonance frequency of his own building

Question: What unforeseen problem caused Tesla to hit his experiment with a sledgehammer?


Answer: World Today

Question: What publication published an article about Tesla in 1912?


Answer: eventually split the earth in two

Question: What did Tesla claim his resonant frequencies could do in the World Today article?


Answer: application of electricity

Context: Tesla theorized that the application of electricity to the brain enhanced intelligence. In 1912, he crafted "a plan to make dull students bright by saturating them unconsciously with electricity," wiring the walls of a schoolroom and, "saturating [the schoolroom] with infinitesimal electric waves vibrating at high frequency. The whole room will thus, Mr. Tesla claims, be converted into a health-giving and stimulating electromagnetic field or 'bath.'" The plan was, at least provisionally approved by then superintendent of New York City schools, William H. Maxwell.

Question: What did Tesla think could improve the brain's intelligence?


Answer: saturating them unconsciously with electricity

Question: What was Tesla's plan to make students "bright"?


Answer: William H. Maxwell

Question: Who approved of this plan?


Answer: superintendent of New York City schools

Question: What was Maxwell's job?


Answer: overseas

Context: Before World War I, Tesla sought overseas investors. After the war started, Tesla lost the funding he was receiving from his patents in European countries. Eventually, he sold Wardenclyffe for $20,000 ($472,500 in today's dollars). In 1917, around the time that the Wardenclyffe Tower was demolished by Boldt to make the land a more viable real estate asset, Tesla received AIEE's highest honor, the Edison Medal.

Question: Where did Tesla look for investors prior to WWI?


Answer: lost

Question: What happened to Tesla's funding once the war begun?


Answer: sold

Question: What did he do with Wardenclyffe?


Answer: $20,000

Question: How much did Tesla receive from the sale of Wardenclyffe?


Answer: the Edison Medal.

Question: What award was given to Tesla?


Answer: Electrical Experimenter

Context: In the August 1917 edition of the magazine Electrical Experimenter Tesla postulated that electricity could be used to locate submarines via using the reflection of an "electric ray" of "tremendous frequency," with the signal being viewed on a fluorescent screen (a system that has been noted to have a superficial resemblance to modern radar). Tesla was incorrect in his assumption that high frequency radio waves would penetrate water but Émile Girardeau, who helped develop France's first radar system in the 1930s, noted in 1953 that Tesla's general speculation that a very strong high frequency signal would be needed was correct stating "(Tesla) was prophesying or dreaming, since he had at his disposal no means of carrying them out, but one must add that if he was dreaming, at least he was dreaming correctly.":266

Question: In what magazine did Tesla talk about reflecting electricity off of submarine's hulls?


Answer: fluorescent screen

Question: How would the operator of observe the reflected signal?


Answer: radar

Question: What later invention was Tesla's idea similar to?


Answer: Émile Girardeau

Question: Who played a part in the development of radar in France?


Answer: Thomas Edison and Nikola Tesla

Context: On 6 November 1915, a Reuters news agency report from London had the 1915 Nobel Prize in Physics awarded to Thomas Edison and Nikola Tesla; however, on 15 November, a Reuters story from Stockholm stated the prize that year was being awarded to Sir William Henry Bragg and William Lawrence Bragg "for their services in the analysis of crystal structure by means of X-rays.":245 There were unsubstantiated rumors at the time that Tesla and/or Edison had refused the prize.:245 The Nobel Foundation said, "Any rumor that a person has not been given a Nobel Prize because he has made known his intention to refuse the reward is ridiculous"; a recipient could only decline a Nobel Prize after he is announced a winner.:245

Question: Who did Reuters claim won the 1915 Nobel prize in Physics?


Answer: Sir William Henry Bragg and William Lawrence Bragg

Question: Who actually won the prize?


Answer: Tesla and/or Edison had refused the prize

Question: What was the rumored reason Edison and Tesla were not awarded the prize?


Answer: announced a winner

Question: According to the Nobel Foundation what has to happen before someone can decline a prize?


Answer: animosity toward each other

Context: There have been subsequent claims by Tesla biographers that Edison and Tesla were the original recipients and that neither was given the award because of their animosity toward each other; that each sought to minimize the other's achievements and right to win the award; that both refused ever to accept the award if the other received it first; that both rejected any possibility of sharing it; and even that a wealthy Edison refused it to keep Tesla from getting the $20,000 prize money.:245

Question: What was another possible reason that Tesla and Edison did not get the award?.


Answer: 38

Context: In the years after these rumors, neither Tesla nor Edison won the prize (although Edison did receive one of 38 possible bids in 1915 and Tesla did receive one of 38 possible bids in 1937).

Question: How many possible bids for the prize were there in 1915?


Answer: Edison

Question: Who received a bid in 1915?


Answer: 1937

Question: In what year did Tesla receive a Nobel Prize bid?


Answer: U.S. Patent 1,655,114

Context: In 1928, Tesla received his last patent, U.S. Patent 1,655,114, for a biplane capable of taking off vertically (VTOL aircraft) and then be "gradually tilted through manipulation of the elevator devices" in flight until it was flying like a conventional plane. Tesla thought the plane would sell for less than $1,000.:251 Although the aircraft was probably impractical, it may be the earliest known design for what became the tiltrotor/tilt-wing concept as well as the earliest proposal for the use of turbine engines in rotor aircraft.[improper synthesis?]

Question: What was the patent number for Tesla's final patent?


Answer: VTOL aircraft

Question: For what invention was U.S. Patent 1,655,114 granted?


Answer: less than $1,000

Answer: $125 per month

Context: Starting in 1934, the Westinghouse Electric & Manufacturing Company began paying Tesla $125 per month as well as paying his rent at the Hotel New Yorker, expenses the Company would pay for the rest of Tesla's life. Accounts on how this came about vary. Several sources say Westinghouse was worried about potential bad publicity surrounding the impoverished conditions their former star inventor was living under. It has been described as being couched in the form of a "consulting fee" to get around Tesla's aversion to accept charity, or by one biographer (Marc Seifer), as a type of unspecified settlement.

Question: What was Tesla's salary from Westinghouse in 1934?


Answer: rent at the Hotel New Yorker

Question: What other compensation did Tesla get from Westinghouse?


Answer: for the rest of Tesla's life

Question: For how long did Tesla receive this compensation?

Answer: feed the pigeons

Context: In the fall of 1937, after midnight one night, Tesla left the Hotel New Yorker to make his regular commute to the cathedral and the library to feed the pigeons. While crossing a street a couple of blocks from the hotel, Tesla was unable to dodge a moving taxicab and was thrown heavily to the ground. Tesla's back was severely wrenched and three of his ribs were broken in the accident (the full extent of his injuries will never be known; Tesla refused to consult a doctor—an almost lifelong custom). Tesla didn't raise any question as to who was at fault and refused medical aid, only asking to be taken to his hotel via cab. Tesla was bedridden for some months and was unable to continue feeding pigeons from his window; soon, they failed to come. In early 1938, Tesla was able to get up. He at once resumed the pigeon-feeding walks on a much more limited scale, but frequently had a messenger act for him.

Answer: charged particle beam weapons

Context: During the same year, Tesla wrote a treatise, The Art of Projecting Concentrated Non-dispersive Energy through the Natural Media, concerning charged particle beam weapons. Tesla published the document in an attempt to expound on the technical description of a "superweapon that would put an end to all war." This treatise is currently in the Nikola Tesla Museum archive in Belgrade. It describes an open-ended vacuum tube with a gas jet seal that allows particles to exit, a method of charging particles to millions of volts, and a method of creating and directing non-dispersive particle streams (through electrostatic repulsion). Tesla tried to interest the US War Department, the United Kingdom, the Soviet Union, and Yugoslavia in the device.
