Question: Charlie Ward Jr. (born October 12, 1970) is a retired American professional NBA basketball player, college football Heisman Trophy winner, Davey O'Brien Award winner and a Major League Baseball draftee. Despite his NCAA football success, Ward was one of the very few players who won a Heisman trophy but was not drafted in the NFL draft. He won the College Football National Championship Game with the Florida State University Seminoles. Ward played several years with the New York Knicks and started in the NBA Finals.

Upon graduation, Ward stated he was undecided about professional basketball or football and made it clear that he would not consider playing in the NFL unless selected in the first round of the 1994 NFL Draft. Ward proclaimed that he "deserved to" be a first-rounder. Ward's mother reported that the family was told he "was probably a third- to fifth-round pick." Because teams did not want to waste a first-round pick on a player that might eventually choose the NBA, and because of his smaller stature, Ward was not selected in the first round of the NFL Draft. Instead of pursuing a career as a football player in the NFL, and having been chosen in the 1st round (26th overall) of the 1994 NBA Draft by the New York Knicks, he began his career in the NBA as a point guard. An inquiry was made during Ward's rookie year with the Knicks for him to become the backup quarterback for Joe Montana of the Kansas City Chiefs, but Ward declined. To this day, Ward is the only Heisman Trophy winner to play in the NBA.  Ward played sparingly in his rookie year under head coach Pat Riley, but the Knicks organization referred to him as "the point guard of the future." When assistant coach Jeff Van Gundy took over the head coaching position, Ward's time on the floor began to increase, becoming the primary backup for point guard Derek Harper. He became a fan favorite in New York for his hard work ethic and unselfish play. During his NBA career, Ward established himself as a good three-point shooter, a reliable ball distributor, and a respected floor leader. Ward was selected to participate in the 1998 NBA All-Star three-point competition, finishing fourth in the event. He soon helped the Knicks reach the 1999 NBA Finals before falling to the San Antonio Spurs. Ward was traded to the Phoenix Suns in February 2004 as part of the blockbuster trade that brought Stephon Marbury to the Knicks and was promptly cut by the Suns for salary purposes. Ward spent the remainder of the season with the Spurs and signed a contract with the Houston Rockets the following summer. After maintaining relatively good health over his first decade in the league, injuries caused Ward to miss most of the 2004-05 season. Because of his injuries Ward retired.  During his time with the Knicks, Ward was often called the "best quarterback in New York" due to the struggles that the New York Jets and New York Giants had at the position.  Off the court, Ward became known for his extensive charitable work through groups like the Fellowship of Christian Athletes. In 2011, at the NCAA Final Four, Ward received the John Wooden Keys to Life award given for continued excellence and integrity on and off the court.  Ward established The aWard Foundation to enhance the lives of young people through sports based mentoring and educational programs.

Problem: Claudius Ptolemy (; Greek: Klaudios Ptolemaios, Klaudios Ptolemaios [klawdios ptoleme:os]; Latin: Claudius Ptolemaeus; c. AD 100 - c. 170) was a Greco-Roman mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou

Ptolemy's Almagest is the only surviving comprehensive ancient treatise on astronomy. Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. Ptolemy, however, claimed to have derived his geometrical models from selected astronomical observations by his predecessors spanning more than 800 years, though astronomers have for centuries suspected that his models' parameters were adopted independently of observations. Ptolemy presented his astronomical models in convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a star catalogue, which is a version of a catalogue created by Hipparchus. Its list of forty-eight constellations is ancestral to the modern system of constellations, but unlike the modern system they did not cover the whole sky (only the sky Hipparchus could see). Across Europe, the Middle East and North Africa in the Medieval period, it was the authoritative text on astronomy, with its author becoming an almost mythical figure, called Ptolemy, King of Alexandria. The Almagest was preserved, like most of extant Classical Greek science, in Arabic manuscripts (hence its familiar name). Because of its reputation, it was widely sought and was translated twice into Latin in the 12th century, once in Sicily and again in Spain. Ptolemy's model, like those of his predecessors, was geocentric and was almost universally accepted until the appearance of simpler heliocentric models during the scientific revolution.  His Planetary Hypotheses went beyond the mathematical model of the Almagest to present a physical realization of the universe as a set of nested spheres, in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an average distance of 1,210 Earth radii, while the radius of the sphere of the fixed stars was 20,000 times the radius of the Earth.  Ptolemy presented a useful tool for astronomical calculations in his Handy Tables, which tabulated all the data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon. Ptolemy's Handy Tables provided the model for later astronomical tables or zijes. In the Phaseis (Risings of the Fixed Stars), Ptolemy gave a parapegma, a star calendar or almanac, based on the hands and disappearances of stars over the course of the solar year.
