Order of Australia

The Order of Australia is an order of chivalry established on 14 February 1975 by Elizabeth II, Queen of Australia, to recognise Australian citizens and other persons for achievement or meritorious service. Before the establishment of the order, Australian citizens would receive British honours.

The Queen of Australia is Sovereign Head of the Order, while the Governor-General is Principal Companion/Dame/Knight (as relevant at the time) and Chancellor of the Order. The Governor-General's Official Secretary is Secretary of the Order.

Classes

The order is divided into a general and a military division. The five classes of appointment to the order are, in descending order of seniority:

Big O notation

In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.

Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.

Australia (/ɒˈstreɪliə/, /ə-/, colloquially /-jə/), officially known as the Commonwealth of Australia, is an Oceanian country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the world's sixth-largest country by total area. Neighbouring countries include Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east.

For about 50,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians, who spoke languages grouped into roughly 250 language groups. After the European discovery of the continent by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and initially settled through penal transportation to the colony of New South Wales from 26 January 1788. The population grew steadily in subsequent decades; the continent was explored and an additional five self-governing crown colonies were established. On 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Since federation, Australia has maintained a stable liberal democratic political system that functions as a federal parliamentary democracy and constitutional monarchy comprising six states and several territories. The population of 24 million is highly urbanised and heavily concentrated in the eastern states and on the coast.

Sachin Tendulkar

Sachin Ramesh Tendulkar (ⁱ/ˌsətʃɪn tɛnˈduːlkər/; born 24 April 1973) is a former Indian cricketer and captain, widely regarded as one of the greatest batsmen of all time. He took up cricket at the age of eleven, made his Test debut on 15 November 1989 against Pakistan in Karachi at the age of sixteen, and went on to represent Mumbai domestically and India internationally for close to twenty-four years. He is the only player to have scored one hundred international centuries, the first batsman to score a double century in a One Day International, holds the record for most number of runs in both ODI and Test cricket, the only player to complete more than 30,000 runs in international cricket.

In 2002 just half way through his career, Wisden Cricketers' Almanack ranked him the second greatest Test batsman of all time, behind Don Bradman, and the second greatest ODI batsman of all time, behind Viv Richards. Later in his career, Tendulkar was a part of the Indian team that won the 2011 World Cup, his first win in six World Cup appearances for India. He had previously been named "Player of the Tournament" at the 2003 edition of the tournament, held in South Africa. In 2013, he was the only Indian cricketer included in an all-time Test World XI named to mark the 150th anniversary of Wisden Cricketers' Almanack.
