Reconnaissance satellite

A reconnaissance satellite or intelligence satellite is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type took photographs ejected canisters of photographic film which would descend back down into Earth's atmosphere. Corona capsules were retrieved in mid-air. Spacecraft had digital imaging systems and downloaded the images via encrypted radio links. In the United States, most information available is on programs that existed up to 1972, as this information has been declassified due to its age; some information about programs prior to that time is still classified, a small amount of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassified on occasion, or leaked, as in the case of KH-11 photographs which were sent to Jane's Defence Weekly in 1984. On 16 March 1955, the United States Air Force ordered the development of an advanced reconnaissance satellite to provide continuous surveillance of "preselected areas of the Earth" in order "to determine the status of a potential enemy’s war-making capability".

There are several major types of reconnaissance satellite. Missile early warning Provides warning of an attack by detecting ballistic missile launches. Earliest known are Missile Defense Alarm System. Nuclear explosion detection characterizes nuclear explosions in space. Vela is the earliest known. Photo surveillance Provides imaging of earth from space. Images can be close-look telephoto. Corona is the earliest known. Spectral imaging is commonplace. Electronic reconnaissance Signals intelligence, intercepts stray radio waves. Samos-F is the earliest known. Radar imaging Most space-based radars use synthetic aperture radar. Can be used at night or through cloud cover. Earliest known are the Soviet US-A series. Examples of reconnaissance satellite missions: High resolution photography Measurement and Signature Intelligence Communications eavesdropping Covert communications Monitoring of nuclear test ban compliance Detection of missile launchesOn 28 August 2013, it was thought that "a $1-billion high-powered spy satellite capable of snapping pictures detailed enough to distinguish the make and model of an automobile hundreds of miles below" was launched from California's Vandenberg Air Force Base using a Delta IV Heavy launcher, America's highest-payload space launch vehicle.

On 17 February 2014, a Russian Kosmos-1220 launched in 1980 and used for naval missile targeting until 1982, made an uncontrolled atmospheric entry. Reconnaissance satellites have been used to enforce human rights, through the Satellite Sentinel Project, which monitors atrocities in Sudan and South Sudan. During his 1980 State of the Union Address, President Jimmy Carter explained how all of humanity benefited from the presence of American spy satellites:...photo-reconnaissance satellites, for example, are enormously important in stabilizing world affairs and thereby make a significant contribution to the security of all nations. Additionally, companies such as GeoEye and DigitalGlobe have provided commercial satellite imagery in support of natural disaster response and humanitarian missions. During the 1950s, a Soviet hoax had led to American fears of a bomber gap. In 1968, after gaining satellite photography, the United States' intelligence agencies were able to state with certainty that "No new ICBM complexes have been established in the USSR during the past year."

President Lyndon B. Johnson told a gathering in 1967: I wouldn't want to be quoted on this... We've spent $35 or $40 billion on the space program, and if nothing else had come out of it except the knowledge that we gained from space photography, it would be worth ten times what the whole program has cost. Because tonight we know how many missiles the enemy has and, it turned out, our guesses were way off. We were doing things. We were building things. We were harboring fears. Spy satellites are seen in spy fiction and military fiction; some works of fiction that focus on spy satellites include: The OMAC Project Enemy of the State Body of Lies Ice Station Zebra Parmanu: The Story of Pokhran Defense Support Program European Union Satellite Centre List of intelligence gathering disciplines List of Kosmos satellites National Reconnaissance Office Satcom on the Move Kupperberg, Paul.

Charing Cross Road

Charing Cross Road is a street in central London running north of St Martin-in-the-Fields to St Giles Circus and becomes Tottenham Court Road. It is so called because it leads from the north in the direction of Charing Cross at the south side of Trafalgar Square, which it connects via St Martin's Place and the motorised east side of the square. What is now Charing Cross road was two narrow streets in the West End, Crown Street and Castle Street; the development of Regent Street in the mid-18th century coincided with not only the building up of great fields west of the area but Westminster Bridge, built as central London and the wider estuary's second bridge after more than a century of pressure, in 1750. These pressures therefore congested the north-south axis of the inner West End as much as the relieved London Bridge area. A major increase in traffic occurred around Piccadilly Circus, Charing Cross and Oxford Street, much of it destined from/to Tottenham Court Road and nearby routes to all northerly directions.

Charing Cross Road was therefore developed, in conjunction with Shaftesbury Avenue, by the Metropolitan Board of Works under an 1877 Act of Parliament. The Act's total costs, including demolition and rebuilding of many rows of buildings across London was £778,238; the two streets and others such as the Thames Embankment, Northumberland Avenue and the Kingsway-Aldwych superstructure were built to improve traffic flow through central London. The scheme abolished some of the worst slums in London which delayed progress in construction while they were rehoused; the new road met the disapprobation of Mervyn Macartney who said of it in an 1899 article: "Perhaps the worst is Charing Cross Road. It has no end. Amorphous, hideous in its tortuous course, it is a monument of the ineptitude and incompetence of its creators." Charing Cross Road is renowned for second-hand bookshops. The section from Leicester Square Underground station to Cambridge Circus is home to specialist bookshops, more general second-hand and antiquarian shops such as Quinto Bookshop, Henry Pordes and Any Amount of Books.

Most of these shops are located on the ground floor of a block owned by a housing association, which decided in 2001 to raise the rents to bring them closer to the market level. This was opposed by the book dealers, who felt that they were providing a valuable service and contributing to the unique character of the area, should not be treated in this way by a not-for-profit body; the association's counter-argument was that if the booksellers did not pay a market rent they were being subsidised by its low-income tenants. The booksellers attracted a reduced rent increase was imposed. Several of the bookshops closed nonetheless, including Silver Moon, reputedly Europe's largest women's interest bookshop, which became part of Foyles. Other shops closed more Zwemmers art bookshop, Shipley the art bookshop in December 2008 and Murder One in 2009. Smaller second-hand and specialist antiquarian bookshops can be found on the adjoining Cecil Court; the northern section between Cambridge Circus and Oxford Street includes more generalist bookshops such as the venerable Foyles.

A long-standing correspondence between New York City-based author Helene Hanff and the staff of a bookshop on the street, Marks & Co. was the inspiration for the book 84, Charing Cross Road. The book was made into a 1987 film starring Anne Bancroft and Anthony Hopkins and into a play and a BBC radio drama. 84 Charing Cross Road, located just north of Cambridge Circus, has not been a bookshop for many years. A small brass plaque, noted by Hanff in her book "Q's Legacy", remains on the stone pilaster facing Charing Cross Road; the music venue the Astoria was located here, as is one of the sites of St Martin's Arts College, opening in 1939. To the northeast of Charing Cross Road are the music shops on Denmark Street. A number of theatres are on or near Charing Cross Road, such as the Phoenix Theatre, the Garrick Theatre and Wyndham's Theatre. Beneath the grille in the traffic island between Charing Cross Road's junction with Old Compton Street, in the middle of the road, the old road signs for the now-vanished Little Compton Street can be seen.

This road once joined Old Compton Street with New Compton Street. On the east side of the road's southern end, at the joining of St Martins Lane, is a statue of Edith Cavell. Towards the north end is the Phoenix Garden – an environmental garden run by local residents. In the Harry Potter books, the Leaky Cauldron pub is located on Charing Cross Road. However, on screen, the locations used are Chez Michelle, a florist in Borough Market, for the exterior in Harry Potter and the Prisoner of Azkaban and the Glass House, an optician in Leadenhall Market, for the entrance in Harry Potter and the Goblet of Fire. Most interior filming was done on set. Citations Sources Book Lovers' London, by Lesley Reader, Metro Publications, paperback, 2nd edition, 2002, ISBN 1-902910-13-3. Leeper Charing Cross Road blog

Ganita Kaumudi

Ganita Kaumudi is a treatise on mathematics written by Indian mathematician Narayana Pandita in 1356. It was an arithmetical treatise alongside the other algebraic treatise called "Bijganita Vatamsa" by Narayana Pandit, it was written as a commentary on the Līlāvatī by Bhāskara II. Gaṇita Kaumudī contains about 475 verses of sūtra, 395 verses of udāharaṇa, it is divided into 14 sections known as vyavahāras: Weights and measures, area, etc. It describes addition, multiplication, square, square root and cube root; the problems of linear and quadratic equations described here are more complex than in earlier works. 63 rules and 82 examples Mathematics pertaining to daily life: “mixture of materials, interest on a principal, payment in instalments, mixing gold objects with different purities and other problems pertaining to linear indeterminate equations for many unknowns” 42 rules and 49 examples Arithmetic and geometric progressions and series. The generalization here was crucial for finding the infinite series for cosine.

28 rules and 19 examples. Geometry. 149 rules and 94 examples. Includes special material on cyclic quadratilerals, such as the “third diagonal”. Excavations. 7 rules and 9 examples. Stacks. 2 rules and 2 examples. Mounds of grain. 2 rules and 3 examples. Shadow problems. 7 rules and 6 examples. Linear integer equations. 69 rules and 36 examples. Quadratic. 17 rules and 10 examples. Includes a variant of the Chakravala method. Ganita Kaumudi contains many results from continued fractions. In the text Narayana Pandita used the knowledge of simple recurring continued fraction in the solutions of indeterminate equations of the type n x 2 + k 2 = y 2. Factorization. Contains Fermat's factorization method. 11 rules and 7 examples. Contains rules for writing a fraction as a sum of unit fractions. 22 rules and 14 examples. Unit fractions were known in Indian mathematics in the Vedic period: the Śulba Sūtras give an approximation of √2 equivalent to 1 + 1 3 + 1 3 ⋅ 4 − 1 3 ⋅ 4 ⋅ 34. Systematic rules for expressing a fraction as the sum of unit fractions had been given in the Gaṇita-sāra-saṅgraha of Mahāvīra.

Nārāyaṇa's Gaṇita-kaumudi gave a few more rules: the section bhāgajāti in the twelfth chapter named aṃśāvatāra-vyavahāra contains eight rules. The first few are: Rule 1. To express 1 as a sum of n unit fractions: 1 = 1 1 ⋅ 2 + 1 2 ⋅ 3 + 1 3 ⋅ 4 + ⋯ + 1 ⋅ n + 1 n Rule 2. To express 1 as a sum of n unit fractions: 1 = 1 2 + 1 3 + 1 3 2 + ⋯ + 1 3 n − 2 + 1 2 ⋅ 3 n − 2 Rule 3. To express a fraction p / q as a sum of unit fractions:Pick an arbitrary number i such that / p is an integer r, write p q = 1 r + i q r and find successive denominators in the same way by operating on the new fraction. If i is always chosen to be the smallest such integer, this is equivalent to the greedy algorithm for Egyptian fractions, but the Gaṇita-Kaumudī's rule does not give a unique procedure, instead states evam iṣṭavaśād bahudhā Rule 4. Given n arbitrary numbers k 1, k 2, …, k n, 1 = k 1 k 2 ⋅ k 1 + k 1 k 3 ⋅ k 2 + ⋯ + k 1 k n ⋅ k n
