Query: Who first landed the quadruple axel?
A quad, or quadruple, is a figure skating jump with at least three but less than four revolutions. Most quadruple jumps have 3 1/2 revolutions; the quadruple Axel has 4 1/2 revolutions, although no figure skater to date has completed this jump in competition. The quadruple toe loop and quadruple Salchow are the two most commonly skated in the discipline. Quadruple jumps have become increasingly common among World and Olympic level men's single skaters, to the point that not having one in a program has come to be seen as a severe handicap. The first person to land a ratified quadruple jump in competition was Canadian Kurt Browning in 1988. In 2002, Miki Ando became the first woman to do so, and she remains one of only two women to have landed a ratified quadruple jump in competition.
Yukari Nakano and Ludmila Nelidina both landed a triple axel in their free skating, together becoming the first female skaters to perform the jump in international competition since Midori Ito landed it at the 1992 Winter Olympics. Nakano landed it first and Nelidina, who skated after her, also performed it successfully.
In the 1996-1997 season Eldredge started off on fire, easily beating Alexei Urmanov (who also skated cleanly) to win Skate America. He controversially lost the Grand Prix final to Elvis Stojko who landed the first ever quadruple-triple combination, but had other errors, including a fall on his 2nd triple axel. Eldredge skated a clean and more complete program, but suffered from the home country scoring of the event in Canada. He regained his U.S title easily, in the absence of defending Champion Rudy Galindo, who was now professional. At the World Championships Eldredge skated a spectacular short program, but due to the very early draw he finished 2nd to Alexei Urmanov who skated near the very end. The top 6 were all clean with triple axel-triple toe combinations. Elvis Stojko though came from 4th to win the gold after a flawless long program with a quadruple-triple combination. Eldredge first singled, then later fell on his 2nd triple axel try, sealing his fate when combined with that he also didn't have a quadruple jump to begin with.
Artur Arturovich Dmitriev (, born 7 September 1992) is a Russian figure skater. He is the 2015 CS Ice Challenge champion, 2014 Cup of Nice silver medalist, and competed at three World Junior Championships, twice finishing in the top ten. He was the first skater ever to attempt a quadruple axel in international competition; however, he landed forwards and received a downgrade on the jump.
After leaving the Royal Conservatory of Brussels, Sax began to experiment with new instrument designs, while his parents continued to make conventional instruments to bring in money. Adolphe's first important invention was an improvement of the bass clarinet design, which he patented at the age of 24. Sax relocated permanently to Paris in 1842 and began working on a new set of instruments. Hector Berlioz was so enamoured of them that he arranged in February 1844 for one of his pieces to be played entirely on Sax's new instruments. These were valved bugles, and although he had not invented the instrument itself, his examples were much more successful than those of his rivals and became known as saxhorns. They came in seven different sizes, and paved the way for the creation of the flugelhorn. Today, saxhorns are sometimes used in concert bands, marching bands and, orchestras. The saxhorn also laid the groundwork for the modern euphonium.
The first commercial horse-drawn double-decker omnibuses were introduced in England in 1847 by Adams & Co. of Fairfield, Bow, then improved upon by John Greenwood, who introduced a new double-decker in 1852.
She held the world record for the ladies' short program score, until the record was broken by Evgenia Medvedeva at the 2016–17 Grand Prix Final. A former prodigy, Asada is the fifth woman and the first junior girl to land the triple axel, accomplishing this feat at the 2004–05 Junior Grand Prix Final. She won her first Grand Prix Final at the age of 15. Considered by many to be the best figure skater in the world at that time, Asada was 87 days too young to compete at the 2006 Winter Olympics. She is the first figure skater in a singles discipline from Asia to win multiple world championships. At the 2013 Skate America, she became the first singles skater, male or female, to win all seven of the current events on the Grand Prix series. She holds 15 Grand Prix series titles, the third most of all time. At the 2014 Winter Olympics, Asada successfully accomplished 8 triple jumps in her individual free skate, becoming the first lady to ever do so, even though 2 were downgraded for lacking rotations. Due to her artistic interpretation, international success since the young age of 15, rare ability to accomplish the triple Axel, and collection of ISU titles surpassing any other ladies singles figure skater during her time, she has established herself as one of the most highly recognized athletes in Japan and is widely considered to be among the best ladies figure skaters of all time.
Alex Hai had begun work in gondolas earlier than Boscolo, in 2007, as Alexandra, but not with a full license because of failures to pass various tests. In June 2017, Hai came out as transgender and said that he had been working "in the body of a woman". Hai is the first openly transgender person to be a gondola operator in Venice. He continues to work as a private gondola operator for hotels and individual clients in a self-run business, Alex Hai Gondola Tours.
Developed with John Akerman of the University of Minnesota and piloted by Jean Piccard in 1937 in Rochester, Minnesota, the first multi-celled balloon was called "The Pleiades" and was made of 98 latex rubber balloons. In a letter to Robert Gray of the Dewey and Almy Chemical Co. later published in "Time" magazine, Piccard describes how he broke balloons with a hunting knife and revolver to control his descent. A TNT charge released the cluster as he expected but sent burning excelsior down that destroyed the first "Pleiades". He suggested to Gray that rock wool in place of excelsior would prevent similar accidents in the future.
The use of split-complex numbers dates back to 1848 when James Cockle revealed his tessarines. William Kingdon Clifford used split-complex numbers to represent sums of spins. Clifford introduced the use of split-complex numbers as coefficients in a quaternion algebra now called split-biquaternions. He called its elements "motors", a term in parallel with the "rotor" action of an ordinary complex number taken from the circle group. Extending the analogy, functions of a motor variable contrast to functions of an ordinary complex variable.
The period around 1840 saw Sax inventing the "clarinette-bourdon", an early unsuccessful design of contrabass clarinet. Around this time he also developed the instrument for which he is best known: the saxophone which he patented on 28 June 1846. The saxophone was invented for use in both orchestras and military bands. By 1846 Sax had designed (on paper at least) a full range of saxophones (from sopranino to subcontrabass). Composer Hector Berlioz wrote approvingly of the new instrument in 1842, but despite his support, saxophones never became standard orchestral instruments. However, their ability to play technical passages easily like woodwinds and also project loudly like brass instruments led them to be included in military bands in France and elsewhere. The saxophone was Sax's signature accomplishment and created his reputation more than any other. This helped secure him a job teaching at the Paris Conservatory in 1857.
The first triple champion of boxing was Bob Fitzsimmons when he added the Light Heavyweight crown to his World Middleweight and Heavyweight belts on November 25, 1903.
Several years later, the Norwegian Captain Roald Amundsen and the Englishman Captain Robert Scott raced to become the first to reach the South Pole. Both expeditions started almost simultaneously but it was Amundsen who reached the pole first on December 14, 1911. Both men carried Tabloid outfits with them.
The first AC commutator-free three-phase induction motors were independently invented by Galileo Ferraris and Nikola Tesla, a working motor model having been demonstrated by the former in 1885 and by the latter in 1887. Tesla applied for US patents in October and November 1887 and was granted some of these patents in May 1888. In April 1888, the "Royal Academy of Science of Turin" published Ferraris's research on his AC polyphase motor detailing the foundations of motor operation. In May 1888 Tesla presented the technical paper "A New System for Alternating Current Motors and Transformers" to the "American Institute of Electrical Engineers" (AIEE)
On 15 June 1919 the first non-stop transatlantic flight by Alcock and Brown crashlanded in Derrygimlagh bog, close to Marconi's transatlantic wireless station. When Captain Alcock spotted the green bog he thought it was a meadow where he could safely land his Vickers Vimy biplane. The plane's landing gear sank into the soft bog and was destroyed. Alcock and Brown had to walk into town with minor injuries. When they returned using the Marconi Railway, the locals had helped themselves to parts of the plane as souvenirs.
Transatlantic flight surpassed ocean liners as the predominant mode of crossing the Atlantic in the mid 20th century. In 1919, the American NC-4 became the first airplane to cross the Atlantic (but in multiple stages). Later that year, a British Vickers Vimy piloted by Alcock and Brown made the first non-stop transatlantic flight from Newfoundland to Ireland. Also in 1919, the British were the first to cross the Atlantic in an airship when the R34 captained by Major George Herbert Scott of the Royal Air Force with his crew and passengers flew from East Fortune, Scotland to Mineola, Long Island, covering a distance of about in about four and a half days; he then made a return trip to England, thus also completing the first double crossing of the Atlantic (east–west–east). In 1927, Charles Lindbergh made the first solo non-stop transatlantic flight in an airplane (between New York City and Paris). The second solo piloting, and the first to carry a passenger, was Clarence Duncan Chamberlin on June 6, 1927. Edward R. Armstrong proposed a string of anchored "seadromes" to refuel planes in a crossing.
In March 2015, Dirk Ahlborn, the CEO of Hyperloop Transportation Technologies (HTT) in El Segundo, California announced a plan to build a hyperloop test system at the Quay Valley site. Ahlborn indicated that construction could begin in 2016 to be completed in 2017 with the first rides to begin in 2018 if his company can raise $100 million in funding. The company has said that this track will be a fully working and operational creation of the hyperloop, but that running speed will be reduced on the shortened track from Hyperloop's full potential. It is not decided whether a 5-mile loop or straight section will be constructed, and it may cross the Interstate bisecting the site. Ahlborn said that speeds up to may be possible. Quay Hays expects to break ground on the new community in 2016, including a working version of the Hyperloop, estimated to cost $100–150 million.
During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton and three other members of his expedition made several firsts in December 1908 – February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship "Fram" became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.
Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936. Some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it is the single main rotor with anti-torque tail rotor configuration that has become the most common helicopter configuration. Tandem rotor helicopters are also in widespread use due to their greater payload capacity. Coaxial helicopters, tiltrotor aircraft, and compound helicopters are all flying today. Quadcopter helicopters pioneered as early as 1907 in France, and other types of multicopter have been developed for specialized applications such as unmanned drones.
The first person to reach all three locations was Edmund Hillary. He reached the top of Everest in May 1953, the South Pole in January 1958 and made it to the North Pole in company with Neil Armstrong in April 1985.
Hillary flew to the North Pole. The first person to reach all three locations on foot was Erling Kagge. He had reached all three by May 1994, being 6 months faster than the next person. On 5 August 1997 Antoine de Choudens (France, 1969–2009) became the only climber to accomplish the Three Poles Challenge on foot without using supplementary oxygen on the Everest climb. Tina Sjögren became the first woman to complete the challenge in 2002.
Perhaps the most widely seen streaker in history was 34-year-old Robert Opel, who streaked across the stage of The Dorothy Chandler Pavilion in Los Angeles flashing a peace sign on national US television at the 46th Academy Awards in 1974. Bemused host David Niven quipped, "Isn't it fascinating to think that probably the only laugh that man will ever get in his life is by stripping off and showing his shortcomings." Later, evidence arose suggesting that Opel's appearance was facilitated as a publicity stunt by the show's producer Jack Haley, Jr.. Robert Metzler, the show's business manager, believed that the incident had been planned in some way; during the dress rehearsal Niven had asked Metzler's wife to borrow a pen so he could write down the famous line, which was thus not the ad-lib it appeared to be. Niven's encounter with the streaker was voted the top Oscars moment by film fans in 2001.
The number of rotations performed in the air determines whether the jump is a single, double, triple, or quadruple (commonly known as a "quad"). The simplest jump begins with a waltz jump which can only be done in a half-leap and is not classified as a single, double, or triple jump. Senior-level male single skaters perform mostly triple and quadruple jumps in competition. Triple jumps other than the Axel are commonly performed by female single skaters. It is extremely rare for a female skater to land a quadruple jump; the only two female single skaters to be credited with quads in competition are Miki Ando, who landed the first quad Salchow in Dec 2002, and Alexandra Trusova, who landed the first quad Toe Loop (and only the second quad Salchow) in March 2018, both at the Junior level. Alexandra Trusova also was the first female to ever land 2 quadruple jumps in competition, the quad salchow and the quad toe loop. She was only 13 years old at the time.
The Axel is a figure skating jump with a forward take off. It is named after Norwegian figure skater Axel Paulsen who, in 1882, was the first skater to perform the jump. Compared to other common figure skating jumps, an Axel has an extra ½ rotation in the air because of its forward take off. Most skaters perform the jump with counterclockwise rotation, taking off from the left forward outside edge and landing on the right back outside edge. The Axel can also be done as a double jump with 2½ rotations, or as a triple jump with 3½ rotations, or a quadruple Axel with 4½ rotations, but no skater has yet accomplished a quadruple Axel in competition.
Goebel was sometimes referred to as the "Quad King" because of his ability to land quadruple jumps. On March 7, 1998, in Lausanne, Switzerland, at the Junior Grand Prix Final, Goebel became the first skater in the world to land a quadruple Salchow, and the first American skater to land a quadruple jump of any kind in competition. International Skating Union officials ratified the jump at the end of the month after watching a video provided by the parents of Tiffany Stiegler / Johnnie Stiegler.
Dmitriev was the first man to land a 3Lz+3F cleanly in competition at the 2018 CS Nebelhorn Trophy, although it received a negative GOE for the lutz's landing on a left inside edge. At the 2018 Rostelecom Cup, Dmitriev attempted a quadruple axel, but landed forwards and fell, receiving both a downgrade and a fall deduction; this made him the first skater ever to attempt a quadruple axel in international competition
