Bell Ringing
Campanology (/kæmpəˈnɒlədʒi/) is both the scientific and artistic study of bells, encompassing their design, tuning, and the methods by which they are rung. It delves into the technology behind bell casting and tuning, as well as the rich history, traditions, and techniques of bellringing as an art form. This field often involves the study of large, tuned bell collections, such as Flemish carillons, Russian zvons, or English "rings of bells" used for change ringing. These unique assemblages come with distinct practices and challenges, and campanology also explores the composition and performance of music written specifically for them. While campanology primarily refers to larger bells typically housed in towers, it is not usually applied to smaller bell collections, such as glockenspiels, tubular bells, or Indonesian gamelans. Instead, the term is most commonly associated with the use of large bells, their musical and historical significance, and the ongoing efforts to pe ...

Inertia
Inertia is the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change. It is one of the fundamental principles in classical physics, and described by Isaac Newton in his Newton%27s_laws_of_motion#First, first law of motion (also known as The Principle of Inertia). It is one of the primary manifestations of mass, one of the core quantitative properties of physical systems. Newton writes: In his 1687 work ''Philosophiæ Naturalis Principia Mathematica'', Newton defined inertia as a property: History and development Early understanding of inertial motion Joseph NeedhamProfessor John H. Lienhard points out the Mozi (book), Mozi – based on a Chinese text from the Warring States period (475–221 BCE) – as having given the first description of inertia. Before the European Renaissance, the prevailing theory of motion in western philosophy was that of Aristotle (384–322 BCE). On the surface ...

The Fens
The Fens or Fenlands in eastern England are a naturally marshy region supporting a rich ecology and numerous species. Most of the fens were drained centuries ago, resulting in a flat, dry, low-lying agricultural region supported by a system of drainage channels and man-made rivers (Ditch, dykes and drains) and automated pumping stations. There have been unintended consequences to this reclamation, as the land level has continued to sink and the dykes have been built higher to protect it from flooding. ''Fen'' is the local term for an individual area of marshland or former marshland. It also designates the type of marsh typical of the area, which has pH, neutral or alkaline water and relatively large quantities of dissolved minerals, but few other plant nutrition, plant nutrients. The Fens are a National Character Area, based on their landscape, biodiversity, geodiversity and economic activity. The Fens lie inland of the Wash, and are an area of nearly in the south east of L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Nine Tailors
''The Nine Tailors'' is a 1934 mystery novel by the British writer Dorothy L. Sayers, her ninth featuring Lord Peter Wimsey. The story is set in the Lincolnshire Fens, and revolves around a group of bell-ringers at the local parish church. The book has been described as Sayers' finest literary achievement, although not all critics were convinced by the mode of death, nor by the amount of technical campanology detail included. Plot Twenty years before the events of the novel, the family of Sir Henry Thorpe, squire of the Fenland village of Fenchurch St Paul, had suffered the theft of a guest's valuable emerald necklace, still unrecovered. The family's then-butler, Geoffrey Deacon, and his accomplice, Nobby Cranton, had been convicted and imprisoned. In 1918, Deacon escaped from prison and disappeared, leaving his wife, Mary, none the wiser. After a man's body in prison clothes was found two years later in a nearby dene-hole, Mary was declared a widow, and became free to marr ...

Bibliography
Bibliography (from and ), as a discipline, is traditionally the academic study of books as physical, cultural objects; in this sense, it is also known as bibliology (from ). English author and bibliographer John Carter describes ''bibliography'' as a word having two senses: one, a list of books for further study or of works consulted by an author (or enumerative bibliography); the other one, applicable for collectors, is "the study of books as physical objects" and "the systematic description of books as objects" (or descriptive bibliography). Etymology The word was used by Greek writers in the first three centuries CE to mean the copying of books by hand. In the 12th century, the word started being used for "the intellectual activity of composing books." The 17th century then saw the emergence of the modern meaning, that of description of books. Currently, the field of bibliography has expanded to include studies that consider the book as a material object. Bibliography, i ...

Fabian Stedman
Fabian Stedman (1640–1713) was an English author and a leading figure in the early history of campanology, particularly in the field of method ringing. He had a key role in publishing two books ''Tintinnalogia'' (1668 with Richard Duckworth) and ''Campanalogia'' (1677 – written solely by him) which are the first two publications on the subject. He is also regarded as being a pioneer in the branch of mathematics known as Group theory. Life Fabian Stedman was born in Yarkhill, Herefordshire, the third son to Reverend Francis Stedman. His father Francis Stedman was born in Aston Munslow, Shropshire in 1598, who took Holy Orders at Yarkhill in 1625. Francis had seven children by two wives. The eldest was Francis Junior who followed his father and became Rector of the parish of Stoke Lacy, Herefordshire in 1660. Fabian Stedman was born in 1640 and baptised at Yarkhill Church on 7 December of that year. At the age of 15 he went to London to learn the trade of master printing, appren ...

English Restoration
The Stuart Restoration was the reinstatement in May 1660 of the Stuart monarchy in Kingdom of England, England, Kingdom of Scotland, Scotland, and Kingdom of Ireland, Ireland. It replaced the Commonwealth of England, established in January 1649 after the execution of Charles I, with his son Charles II of England, Charles II. The Commonwealth of England had been governed by Lord Protector Oliver Cromwell and then his son Richard Cromwell. The term is also used to describe the reign of Charles II (1660–1685), and sometimes that of his younger brother King James II, James II (1685–1688). The Protectorate After Richard Cromwell, Lord Protector from 1658 to 1659, ceded power to the Rump Parliament, Charles Fleetwood and John Lambert (general), John Lambert then dominated government for a year. On 20 October 1659, George Monck, the governor of Scotland under the Cromwells, marched south with his army from Scotland to oppose Fleetwood and Lambert. Lambert's a ...

Factorial
In mathematics, the factorial of a non-negative denoted is the Product (mathematics), product of all positive integers less than or equal The factorial also equals the product of n with the next smaller factorial: \begin n! &= n \times (n-1) \times (n-2) \times (n-3) \times \cdots \times 3 \times 2 \times 1 \\ &= n\times(n-1)!\\ \end For example, 5! = 5\times 4! = 5 \times 4 \times 3 \times 2 \times 1 = 120. The value of 0! is 1, according to the convention for an empty product. Factorials have been discovered in several ancient cultures, notably in Indian mathematics in the canonical works of Jain literature, and by Jewish mystics in the Talmudic book ''Sefer Yetzirah''. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, where its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there In mathematical analysis, factorials are used in power series for the ex ...

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of Rigour#Mathematics, mathematically rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can use Conditional (computer programming), conditionals to divert the code execution through various routes (referred to as automated decision-making) and deduce valid inferences (referred to as automated reasoning). In contrast, a Heuristic (computer science), heuristic is an approach to solving problems without well-defined correct or optimal results.David A. Grossman, Ophir Frieder, ''Information Retrieval: Algorithms and Heuristics'', 2nd edition, 2004, For example, although social media recommender systems are commonly called "algorithms", they actually rely on heuristics as there is no truly "correct" recommendation.

Steinhaus–Johnson–Trotter Algorithm
The Steinhaus–Johnson–Trotter algorithm or Johnson–Trotter algorithm, also called plain changes, is an algorithm named after Hugo Steinhaus, Selmer M. Johnson and Hale F. Trotter that generates all of the permutations of n elements. Each two adjacent permutations in the resulting sequence differ by swapping two adjacent permuted elements. Equivalently, this algorithm finds a Hamiltonian cycle in the permutohedron, a polytope whose vertices represent permutations and whose edges represent swaps. This method was known already to 17th-century English Change ringing, change ringers, and Robert Sedgewick (computer scientist), Robert Sedgewick calls it "perhaps the most prominent permutation enumeration algorithm". A version of the algorithm can be implemented in such a way that the average time per permutation is constant. As well as being simple and computationally efficient, this algorithm has the advantage that subsequent computations on the generated permutations may be s ...

Permutations
In mathematics, a permutation of a Set (mathematics), set can mean one of two different things: * an arrangement of its members in a sequence or linear order, or * the act or process of changing the linear order of an ordered set. An example of the first meaning is the six permutations (orderings) of the set : written as tuples, they are (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). Anagrams of a word whose letters are all different are also permutations: the letters are already ordered in the original word, and the anagram reorders them. The study of permutations of finite sets is an important topic in combinatorics and group theory. Permutations are used in almost every branch of mathematics and in many other fields of science. In computer science, they are used for analyzing sorting algorithms; in quantum physics, for describing states of particles; and in biology, for describing RNA sequences.
