John Harrison was an English carpenter and clockmaker who invented the marine chronometer, a long-sought-after device for solving the problem of calculating longitude while at sea.
A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is an approximate harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates. From its invention in 1656 by Christiaan Huygens, inspired by Galileo Galilei, until the 1930s, the pendulum clock was the world's most precise timekeeper, accounting for its widespread use. Throughout the 18th and 19th centuries, pendulum clocks in homes, factories, offices, and railroad stations served as primary time standards for scheduling daily life, work shifts, and public transportation. Their greater accuracy allowed for the faster pace of life which was necessary for the Industrial Revolution. The home pendulum clock was replaced by less-expensive synchronous electric clocks in the 1930s and '40s. Pendulum clocks are now kept mostly for their decorative and antique value.
The University of Manchester is a public research university in Manchester, England. The main campus is south of Manchester City Centre on Oxford Road. The university owns and operates major cultural assets such as the Manchester Museum, The Whitworth art gallery, the John Rylands Library, the Tabley House Collection and the Jodrell Bank Observatory – a UNESCO World Heritage Site. The University of Manchester is considered a red brick university, a product of the civic university movement of the late 19th century. The current University of Manchester was formed in 2004 following the merger of the University of Manchester Institute of Science and Technology (UMIST) and the Victoria University of Manchester. This followed a century of the two institutions working closely with one another.
Corpus Christi College is one of the constituent colleges of the University of Oxford in the United Kingdom. Founded in 1517, it is the 12th oldest college in Oxford.
Corpus Christi College is a constituent college of the University of Cambridge. From the late 14th century to the early 19th century it was also commonly known as St Benet's College.
George Graham, FRS was an English clockmaker, inventor, and geophysicist, and a Fellow of the Royal Society.
The grasshopper escapement is a low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, part of every mechanical clock, is the mechanism that gives the clock's pendulum periodic pushes to keep it swinging, and each swing releases the clock's gears to move forward by a fixed amount, thus moving the hands forward at a steady rate. The grasshopper escapement was used in a few regulator clocks built during Harrison's time, and a few others over the years, but has never seen wide use. The term "grasshopper" in this connection, apparently from the kicking action of the pallets, first appears in the Horological Journal in the late 19th century.
An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's hands. The impulse action transfers energy to the clock's timekeeping element to replace the energy lost to friction during its cycle and keep the timekeeper oscillating. The escapement is driven by force from a coiled spring or a suspended weight, transmitted through the timepiece's gear train. Each swing of the pendulum or balance wheel releases a tooth of the escapement's escape wheel, allowing the clock's gear train to advance or "escape" by a fixed amount. This regular periodic advancement moves the clock's hands forward at a steady rate. At the same time, the tooth gives the timekeeping element a push, before another tooth catches on the escapement's pallet, returning the escapement to its "locked" state. The sudden stopping of the escapement's tooth is what generates the characteristic "ticking" sound heard in operating mechanical clocks and watches.
A kettle, sometimes called a tea kettle or teakettle, is a device specialized for boiling water, commonly with a lid, spout, and handle. There are two main types: the stovetop kettle, which uses heat from a hob, and the electric kettle, which is a small kitchen appliance with an internal heating element.
In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each swing, and allows the clock's wheels to advance a fixed amount with each swing, moving the clock's hands forward. The anchor escapement was so named because one of its principal parts is shaped vaguely like a ship's anchor.
Sir Martin John Taylor, FRS is a British mathematician and academic. He was Professor of Pure Mathematics at the School of Mathematics, University of Manchester and, prior to its formation and merger, UMIST where he was appointed to a chair after moving from Trinity College, Cambridge in 1986. He was elected Warden of Merton College, Oxford on 5 November 2009, took office on 2 October 2010 and retired in September 2018.
The Faculty of Science and Engineering (FSE) is one of the three faculties that comprise the University of Manchester in northern England. Established in October 2004, the faculty was originally called the Faculty of Engineering and Physical Sciences. It was renamed in 2016, following the abolition of the Faculty of Life Science and the incorporation of some aspects of life sciences into the departments of Chemistry and Earth and Environmental Sciences. It is organised into 2 schools and 9 departments: Chemical Engineering and Analytical Science; Chemistry; Computer Science; Earth and Environmental Sciences; Physics and Astronomy; Electrical & Electronic Engineering; Materials; Mathematics; and Mechanical, Aerospace and Civil Engineering.
The Corpus Clock, also known as the Grasshopper clock, is a large sculptural clock at street level on the outside of the Taylor Library at Corpus Christi College, University of Cambridge, in the United Kingdom, at the junction of Bene't Street and Trumpington Street, looking out over King's Parade. It was conceived and funded by John C. Taylor, an old member of the college.
Michael David Cobham was a British film and TV producer and director, best known for the film Tarka the Otter. He was also a first-class cricketer.
Robert Townley Caldwell was the Master of Corpus Christi College, Cambridge from 1906 to 1914.
John Green was an English clergyman and academic. He became the chaplain of Charles Seymour, 6th Duke of Somerset, and Vice-Chancellor of the University of Cambridge.
Gail Trimble is a British academic specialising in Latin poetry and literary form. She was captain of the Corpus Christi College team for the BBC television programme University Challenge in 2009 and scored a high proportion of the team's points. While her team won the challenge, they were subsequently disqualified after it was found that one of her teammates had finished his studies while the show was being recorded. Trimble has continued to appear on quiz programmes. She is now a fellow and tutor in Classics at Trinity College, Oxford.
John Copcot, DD was an English cleric and academic, becoming Vice-Chancellor of the University of Cambridge and Master of Corpus Christi College, Cambridge.
John Lamb, was an academic and Anglican priest in the first half of the nineteenth century.
