Jeopardy! is an American television quiz show featuring trivia in history, literature, the arts, pop culture, science, sports, geography, wordplay, and other topics. The show has a unique answer-and-question format in which contestants are presented with clues in the form of answers, and must phrase their responses in question form.

The show has enjoyed a decades-long broadcast history in the United States since its creation by Merv Griffin in 1964. It debuted on NBC on March 30, 1964, and the series was part of the network's daytime lineup until January 3, 1975. On September 9, 1974, a weekly nighttime syndicated edition of Jeopardy! debuted; this series ran concurrently with the NBC series until its final episode and continued to air on local stations until September 5, 1975. A revival of the daytime series debuted on October 2, 1978 and ran until March 2, 1979. All three of these versions of Jeopardy! were hosted by Art Fleming, with Don Pardo serving as announcer for the original NBC series, and John Harlan announcing the 1978 revival.

Thomas Hornsby FRS (1733, London – 1810, London) was a British astronomer and mathematician.

Hornsby became a Fellow of Corpus Christi College, Oxford in 1760.

He occupied the Savilian Chair of Astronomy at Oxford University from 1763. In the same year, he became professor of experimental philosophy.

Hornsby was especially concerned with the observation of the transit of Venus. In 1761, he observed the transit of Venus from Shirburn Castle, in Oxfordshire, the possession of the Earl of Macclesfield. George Parker, 2nd Earl of Macclesfield (ca. 1695-1764), celebrated as an astronomer, had spent most of his time conducting astronomical observations at Shirburn Castle; here he had built an observatory and a chemical laboratory.

In 1769, Hornsby viewed Venus' transit at the Tower of the Five Orders, where the Bodleian Library is situated.

In the periodical Philosophical Transactions, Hornsby published a comparative analysis of 1761 transit (1763); a plan for suitable viewing stations for 1769, including possible locations in the Pacific (1765); a description of organising and reporting observing groups in Oxford (1769); and a comparative analysis of the 1769 transit (1771).
