Babbage
Charles Babbage (; 26 December 1791 – 18 October 1871) was an English polymath. A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer. Babbage is considered by some to be " father of the computer". Babbage is credited with inventing the first mechanical computer, the Difference Engine, that eventually led to more complex electronic designs, though all the essential ideas of modern computers are to be found in Babbage's Analytical Engine, programmed using a principle openly borrowed from the Jacquard loom. Babbage had a broad range of interests in addition to his work on computers covered in his book ''Economy of Manufactures and Machinery''. His varied work in other fields has led him to be described as "pre-eminent" among the many polymaths of his century. Babbage, who died before the complete successful engineering of many of his designs, including his Difference Engine and Analytical Eng ...

Benjamin Herschel Babbage
Benjamin Herschel Babbage (6 August 1815 – 22 October 1878) was an English engineer, scientist, explorer and politician, best known for his work in the colony of South Australia He invariably signed his name "B. Herschel Babbage" and was frequently referred to as "Herschel Babbage". He was the son of English mathematician and inventor, Charles Babbage. Early life and family Babbage was born in London, the eldest son of Charles Babbage, the renowned Cambridge mathematician who originated the concept of a programmable computer, and Georgina Whitmore. His uncle on his mother's side was William Wolryche-Whitmore, an MP in the House of Commons who lobbied for the formation of South Australia and introduced the South Australia Foundation Act into the British Parliament. At the age of 18, Babbage became a pupil of the engineer and architect William Chadwell Mylne, with whom he worked on waterworks projects. In the 1840s, he also worked with Isambard Kingdom Brunel, the son of his fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analytical Engine
The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician and computer pioneer Charles Babbage. It was first described in 1837 as the successor to Babbage's difference engine, which was a design for a simpler mechanical calculator. The Analytical Engine incorporated an arithmetic logic unit, control flow in the form of conditional branching and loops, and integrated memory, making it the first design for a general-purpose computer that could be described in modern terms as Turing-complete. In other words, the structure of the Analytical Engine was essentially the same as that which has dominated computer design in the electronic era. The Analytical Engine is one of the most successful achievements of Charles Babbage. Babbage was never able to complete construction of any of his machines due to conflicts with his chief engineer and inadequate funding. It was not until 1941 that Konrad Zuse built the first general-purpose comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ada Lovelace
Augusta Ada King, Countess of Lovelace (''née'' Byron; 10 December 1815 – 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and to have published the first algorithm intended to be carried out by such a machine. As a result, she is often regarded as the first computer programmer. Ada Byron was the only legitimate child of poet Lord Byron and Lady Byron. All of Byron's other children were born out of wedlock to other women. Byron separated from his wife a month after Ada was born and left England forever. Four months later, he commemorated the parting in a poem that begins, "Is thy face like thy mother's my fair child! ADA! sole daughter of my house and heart?" He died in Greece when Ada was eight. Her mother remained bitter and promoted Ada's interest in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Difference Engine
A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage. The name, the difference engine, is derived from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common mathematical functions used in engineering, science and navigation, were, and still are computable with the use of the difference engine's capability of computing logarithmic and trigonometric functions, which can be approximated by polynomials, so a difference engine can compute many useful tables of numbers. History The notion of a mechanical calculator for mathematical functions can be traced back to the Antikythera mechanism of the 2nd century BC, while early modern examples are attributed to Pascal and Leibniz in the 17th century. In 1784 J. H. Müller, an engineer in the Hessian army, devised a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Herschel
Sir John Frederick William Herschel, 1st Baronet (; 7 March 1792 – 11 May 1871) was an English polymath active as a mathematician, astronomer, chemist, inventor, experimental photographer who invented the blueprint and did botanical work. Herschel originated the use of the Julian day system in astronomy. He named seven moons of Saturn and four moons of Uranus – the seventh planet, discovered by his father Sir William Herschel. He made many contributions to the science of photography, and investigated colour blindness and the chemical power of ultraviolet rays. His ''Preliminary Discourse'' (1831), which advocated an inductive approach to scientific experiment and theory-building, was an important contribution to the philosophy of science. Early life and work on astronomy Herschel was born in Slough, Buckinghamshire, the son of Mary Baldwin and astronomer William Herschel. He was the nephew of astronomer Caroline Herschel. He studied shortly at Eton Colle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jacquard Loom
The Jacquard machine () is a device fitted to a loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. The resulting ensemble of the loom and Jacquard machine is then called a Jacquard loom. The machine was patented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving innovations as Jacquard shedding made possible the automatic production of unlimited varieties of complex pattern weaving. The term "Jacquard" is not spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peterhouse, Cambridge
Peterhouse is the oldest constituent college of the University of Cambridge in England, founded in 1284 by Hugh de Balsham, Bishop of Ely. Today, Peterhouse has 254 undergraduates, 116 full-time graduate students and 54 fellows. It is quite often erroneously referred to as ''Peterhouse College'', although the correct name is simply ''Peterhouse''.

Walworth Road
The A215 is an A road in south London, starting at Elephant and Castle and finishing around Shirley. It runs through the London Boroughs of Lambeth, Southwark and Croydon. Beginning as Walworth Road, the A215 becomes Camberwell Road—much of which is a conservation area—after entering the former Metropolitan Borough of Camberwell. Crossing the A202, the A215 becomes Denmark Hill, originally known as Dulwich Hill, but renamed in 1683 to commemorate the marriage of Princess Anne (later Queen Anne) to Prince George of Denmark. After passing Herne Hill railway station the road becomes Norwood Road, Knights Hill, and then Beulah Hill at its crossroads with the A214. Beulah Hill was the site of the Croydon transmitting station, Britain's first independent television transmitter, built by the Independent Television Authority in 1955. Descending towards South Norwood the A215 becomes South Norwood Hill and then Portland Road, just after crossing the A213. A short section starti ...

William Wolryche-Whitmore
William Wolryche-Whitmore (16 September 1787 – 11 August 1858) was a Shropshire landowner and British Whig politician. He held a seat in the House of Commons from 1820 to 1835, representing first Bridgnorth and later Wolverhampton. His sister Georgiana Whitmore (1792–1827) married the English inventor and mathematician Charles Babbage in 1814 and had eight children with him, including Australian settlers Benjamin Herschel Babbage and Dugald Bromhead Babbage. Background William Wolryche-Whitmore was originally plain William Whitmore. His father was also called William Whitmore, a former-sailor and businessman from Southampton, who inherited Dudmaston Hall, at Quatt in Shropshire, from a relative, who was distantly related to the widow of the penultimate Wolryche baronet. His mother was Frances Lyster, who played an important part in reshaping the grounds of Dudmaston. She died in 1792, and the elder William Whitmore remarried Marie Louisa Thomas: from this later marriag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
