Horology (from Greek: ὥρα, "hour, time" and Greek: λόγος, logos, "study, speech"; lit. the study of time) is the art or science of measuring time. Clocks, watches, clockwork, sundials, clepsydras, timers, time recorders and marine chronometers are all examples of instruments used to measure time.

People interested in horology are called horologists. That term is used both by people who deal professionally with timekeeping apparatus (watchmakers, clockmakers), as well as aficionados and scholars of horology. Horology and horologists have numerous organizations, both professional associations and more scholarly societies.

Horological museums and libraries[link]

Horology has a long history^{[chronology citation needed]} and there are many museums and several specialized libraries devoted to the subject. An example is the Royal Greenwich Observatory, which is also the source of the Prime Meridian (longitude 0° 0' 0"), and the home of the first marine timekeepers accurate enough to determine longitude (made by John Harrison). Other horological museums in the London area include the Clockmakers' Museum, and the horological collections at the British Museum, the Science Museum (London) and at the Wallace Collection.

One of the more comprehensive museums dedicated to horology is the Musée international d'horlogerie in La Chaux-de-Fonds (Switzerland). The Musée d'Horlogerie du Locle is a bit smaller but located nearby. One of the better horological museums in Germany is the Deutsches Uhrenmuseum. The two leading specialised horological museums in North America are the National Watch and Clock Museum in Columbia, Pennsylvania, and the American Clock and Watch Museum in Bristol, Connecticut.

An example of a museum devoted to one particular type of clock is the Cuckooland Museum, in the U. K., which hosts the world's largest collection of antique cuckoo clocks.

One of the most comprehensive horological libraries open to the public is the National Watch and Clock Library in Columbia, PA (USA). Other good horological libraries providing public access are at the Musée international d'horlogerie in Switzerland, at the Deutsches Uhrenmuseum in Germany, and at the Guildhall Library in London.

Steven Richardson (born 24 July 1966) is an English professional golfer.

Richardson was born in Windsor, Berkshire. He won the English Amateur in 1989 and turned professional later that year. He made a strong start to his professional career, finishing in 29th place on the European Tour Order of Merit in his rookie season. The following year he won the Girona Open and the Portuguese Open, tied for 5th in the USPGA Championship, and finished second on the Order of Merit to Seve Ballesteros. He also ended the 1992 and 1993 seasons inside the top 20 on the money list, while picking up his third career victory in the Mercedes German Masters.

However Richardson's form began to decline, as he slipped outside the top 50 on the European Tour Order of Merit in 1994. He fell outside the top 100 two years later, and had to visit qualifying school in 1998, 1999 and 2000 to regain his tour card. He finally lost his place on the European Tour at the end of 2001 having failed to come through the qualifying school by a single shot.^[1] He revisited qualifying the following year, but was again unsuccessful.^[2]

Richardson was a member of Europe's losing Ryder Cup team in 1991. He won two points in partnership with Mark James but lost his singles match to Corey Pavin. In 1992 he was a member of the winning English team at the Alfred Dunhill Cup.
