Answer the question at the end by quoting:

Kurt Friedrich Godel (UK: , US: ; German: ['kUat 'go:dl] ( listen); April 28, 1906 - January 14, 1978) was an Austrian, and later American, logician, mathematician, and philosopher.
Godel was born April 28, 1906, in Brunn, Austria-Hungary (now Brno, Czech Republic) into the ethnic German family of Rudolf Godel (1874-1929), the manager of a textile factory, and Marianne Godel (nee Handschuh, 1879-1966). Throughout his life, Godel would remain close to his mother; their correspondence was frequent and wide-ranging. At the time of his birth the city had a German-speaking majority which included his parents. His father was Catholic and his mother was Protestant and the children were raised Protestant. The ancestors of Kurt Godel were often active in Brunn's cultural life. For example, his grandfather Joseph Godel was a famous singer of that time and for some years a member of the "Brunner Mannergesangverein".  Godel automatically became a Czechoslovak citizen at age 12 when the Austro-Hungarian Empire broke up at the end of World War I. According to his classmate Klepetar, like many residents of the predominantly German Sudetenlander, "Godel considered himself always Austrian and an exile in Czechoslovakia". He chose to become an Austrian citizen at age 23. When Germany annexed Austria in 1938, Godel automatically became a German citizen at age 32. After World War II, at the age of 42, he became an American citizen.  In his family, young Kurt was known as Herr Warum ("Mr. Why") because of his insatiable curiosity. According to his brother Rudolf, at the age of six or seven Kurt suffered from rheumatic fever; he completely recovered, but for the rest of his life he remained convinced that his heart had suffered permanent damage. Beginning at age four, Godel suffered from "frequent episodes of poor health," which would continue for his entire life.  Godel attended the Evangelische Volksschule, a Lutheran school in Brunn from 1912 to 1916, and was enrolled in the Deutsches Staats-Realgymnasium from 1916 to 1924, excelling with honors in all his subjects, particularly in mathematics, languages and religion. Although Kurt had first excelled in languages, he later became more interested in history and mathematics. His interest in mathematics increased when in 1920 his older brother Rudolf (born 1902) left for Vienna to go to medical school at the University of Vienna. During his teens, Kurt studied Gabelsberger shorthand, Goethe's Theory of Colours and criticisms of Isaac Newton, and the writings of Immanuel Kant.

Answer the question at the end by quoting:

Kwon Bo-ah (Korean: gweonboa, born November 5, 1986), known professionally as BoA, is a South Korean singer, dancer, composer and actress active in South Korea and Japan. She is referred to as the Queen of Korean Pop. Born and raised in Gyeonggi-do, South Korea, she was discovered by SM Entertainment talent agents when she accompanied her older brother to a talent search.
BoA's second Japanese studio album, Valenti (2003), became her best-selling album, with over 1,249,000 copies sold. In support of the album, BoA launched BoA 1st Live Tour Valenti, her first Japanese concert tour. Later that year, she released two Korean albums, Atlantis Princess and the mini-album Shine We Are!. The former was the fifth-best-selling South Korean record of the year with around 345,000 units sold; the latter sold around 58,000 units.  Her third Japanese studio album, Love & Honesty (2004) was a musical "change in direction": it contained a rock-dance song ("Rock with You") and "harder" R&B. Though the album failed to match Valenti in sales, it topped the Oricon chart for two weeks and became RIAJ-certified triple-platinum. In support of the album, BoA held a tour, Live Concert Tour 2004: Love & Honesty. In contrast with 1st Live Tour, which "emphasized exotic Asian design", the Love & Honesty tour had an "outer-space, sci-fi" theme; among the props were a three-story-high space ship and the robot Asimo. The tour, which started in Saitama and ended in Yokohama, spanned nine performances and attracted approximately 105,000 attendants. Her first compilation album, Best of Soul (2005), however, sold over a million copies, making BoA the first non-Japanese Asian singer to have two million-selling albums in Japan.  BoA reinvented her image on her fourth Korean album, My Name (2004); she left the "cute" and "youthful" style that had characterized previous years and presented herself as "sexy" and "sultry". The album was the beginning of a foray into the Chinese market and contained two songs sung in Mandarin Chinese. The sales of BoA's Korean albums began to decline: the album sold 191,000 units and became the eleventh-best-selling South Korean album of the year. In September 2004, BoA instigated controversy in Japan when she donated W50 million to a memorial project for Korean independence activist and nationalist An Jung-geun.  Her fifth Korean album, Girls on Top (2005), continued her image change. The album portrayed the singer as more "mature and self-confident" and was a "declaration of war on male chauvinism"; the "bohemian" look of the cover photograph represented "freedom and depth", while music videos and album photographs that portrayed BoA in traditional Korean dress brought the "idea of Korean womanhood" into her music. The album also continued BoA's foray into the Chinese market and, like the previous album, contained Mandarin Chinese songs. The album sold less than the previous album; it was the fourteenth-best-selling record of the year in South Korea with 113,000 units sold.
