Background: Dan Gurney was born to Jack Gurney and Roma Sexton. His father, John R. "Jack" Gurney, was a graduate of Harvard Business school with a master's degree. Dan's three uncles were each MIT engineers. His grandfather was F.W. Gurney who was responsible for the invention of the Gurney Ball Bearing.
Context: Upon his retirement from Formula One, Gurney devoted himself full-time to his role as car maker and team owner. He was the sole owner, Chairman and CEO of All American Racers from 1970 until his son, Justin, assumed the title of CEO in early 2011. The team won 78 races (including the Indianapolis 500, the 12 Hours of Sebring, and the 24 Hours of Daytona) and eight championships, while Gurney's Eagle race car customers also won three Indianapolis 500 races and three championships. In 1978, Gurney wrote an open memo to other race car owners with what is now known as the "White Letter" in which Gurney called for a series controlled more by the owners or "actual participants" than under the USAC banner. After much debate, CART was formed with Gurney and other owners like Roger Penske, Pat Patrick, and Bob Fletcher. CART began its first full season of competition in March 1979 and thus the first split in open wheel racing began. AAR withdrew from the CART series in 1986, but enjoyed tremendous success with Toyota in the IMSA GTP series, where in 1992 and 1993 Toyota Eagles won 17 consecutive races, back-to-back Drivers' and Manufacturers' Championships, and wins in the endurance classics of Daytona and Sebring. The team returned to CART as the factory Toyota team in 1996, but left again after the 1999 season when Goodyear withdrew from the series and Toyota ended their relationship with the team. In 2000, Dan campaigned a Toyota Atlantic car for his son, Alex Gurney under the AAR banner. In 1990, Gurney was inducted into the International Motorsports Hall of Fame. He is also a member of the Motorsports Hall of Fame of America, the Sebring International Raceway Hall of Fame, and the West Coast Stock Car Hall of Fame.

Answer:

Background: 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.
Context: At the age of 18, Godel joined his brother in Vienna and entered the University of Vienna. By that time, he had already mastered university-level mathematics. Although initially intending to study theoretical physics, he also attended courses on mathematics and philosophy. During this time, he adopted ideas of mathematical realism. He read Kant's Metaphysische Anfangsgrunde der Naturwissenschaft, and participated in the Vienna Circle with Moritz Schlick, Hans Hahn, and Rudolf Carnap. Godel then studied number theory, but when he took part in a seminar run by Moritz Schlick which studied Bertrand Russell's book Introduction to Mathematical Philosophy, he became interested in mathematical logic. According to Godel, mathematical logic was "a science prior to all others, which contains the ideas and principles underlying all sciences." Attending a lecture by David Hilbert in Bologna on completeness and consistency of mathematical systems may have set Godel's life course. In 1928, Hilbert and Wilhelm Ackermann published Grundzuge der theoretischen Logik (Principles of Mathematical Logic), an introduction to first-order logic in which the problem of completeness was posed: Are the axioms of a formal system sufficient to derive every statement that is true in all models of the system? This became the topic that Godel chose for his doctoral work. In 1929, at the age of 23, he completed his doctoral dissertation under Hans Hahn's supervision. In it, he established the completeness of the first-order predicate calculus (Godel's completeness theorem). He was awarded his doctorate in 1930. His thesis, along with some additional work, was published by the Vienna Academy of Science.
Question: Did he change to another field of study?
Answer: he became interested in mathematical logic.

Background: Michael Gerard Tyson was born in Brownsville, Brooklyn, New York on June 30, 1966. He has an elder brother named Rodney (born c. 1961) and had an elder sister named Denise, who died of a heart attack at age 24 in February 1990. Tyson's biological father is listed as "Purcell Tyson" (who was from Jamaica) on his birth certificate, but the man Tyson had known as his father was Jimmy Kirkpatrick. Kirkpatrick was from Grier Town, North Carolina (a predominantly black neighborhood that was annexed by the city of Charlotte), where he was one of the neighborhood's top baseball players.
Context: Tyson made his professional debut as an 18-year-old on March 6, 1985, in Albany, New York. He defeated Hector Mercedes via a first round knockout. He had 15 bouts in his first year as a professional. Fighting frequently, Tyson won 26 of his first 28 fights by KO or TKO; 16 of those came in the first round. The quality of his opponents gradually increased to journeyman fighters and borderline contenders, like James Tillis, David Jaco, Jesse Ferguson, Mitch Green and Marvis Frazier. His win streak attracted media attention and Tyson was billed as the next great heavyweight champion. D'Amato died in November 1985, relatively early into Tyson's professional career, and some speculate that his death was the catalyst to many of the troubles Tyson was to experience as his life and career progressed. Tyson's first nationally televised bout took place on February 16, 1986, at Houston Field House in Troy, New York against journeyman heavyweight Jesse Ferguson. Tyson knocked down Ferguson with an uppercut in the fifth round that broke Ferguson's nose. During the sixth round, Ferguson began to hold and clinch Tyson in an apparent attempt to avoid further punishment. After admonishing Ferguson several times to obey his commands to box, the referee finally stopped the fight near the middle of the sixth round. The fight was initially ruled a win for Tyson by disqualification (DQ) of his opponent. The ruling was "adjusted" to a win by technical knockout (TKO) after Tyson's corner protested that a DQ win would end Tyson's string of knockout victories, and that a knockout would have been the inevitable result. On November 22, 1986, Tyson was given his first title fight against Trevor Berbick for the World Boxing Council (WBC) heavyweight championship. Tyson won the title by second round TKO, and at the age of 20 years and 4 months became the youngest heavyweight champion in history. Tyson's dominant performance brought many accolades. Donald Saunders wrote: "The noble and manly art of boxing can at least cease worrying about its immediate future, now [that] it has discovered a heavyweight champion fit to stand alongside Dempsey, Tunney, Louis, Marciano and Ali." Tyson intimidated fighters with his strength, combined with outstanding hand speed, accuracy, coordination and timing. Tyson also possessed notable defensive abilities, holding his hands high in the Peek-a-Boo style taught by his mentor Cus D'Amato to slip under and weave around his opponent's punches while timing his own. One of Tyson's trademark moves was a right hook to his opponent's body followed by a right uppercut to his opponent's chin. Lorenzo Boyd, Jesse Ferguson and Jose Ribalta were each knocked down by this combination.
