Canada (ⁱ/ˈkænədə/; French: [ka.na.da]) is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres (3.85 million square miles), making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains; about four-fifths of the country's population of 35 million people live near the southern border. The majority of Canada has a cold or severely cold winter climate, but southerly areas are warm in summer.

The land now called Canada has been inhabited for millennia by various Aboriginal peoples. Beginning in the 15th century, British and French colonies were established on the Atlantic coast, with the first establishment of a region called "Canada" occurring in 1537. As a consequence of various conflicts, the United Kingdom gained and lost territories within British North America until left, in the late 18th century, with what mostly geographically comprises Canada today. Pursuant to the British North America Act, on July 1, 1867, the colonies of Canada, New Brunswick, and Nova Scotia joined to form the autonomous federal Dominion of Canada. This began an accretion of provinces and territories to the self-governing Dominion to the present ten provinces and three territories forming modern Canada. In 1931, Canada achieved near total independence from the United Kingdom with the Statute of Westminster 1931, and full sovereignty was attained when the Canada Act 1982 removed the last remaining ties of legal dependence on the British parliament.

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.

John Cleese

John Marwood Cleese (/ˈkliːz/; born 27 October 1939) is an English actor, comedian, writer and film producer. He achieved success at the Edinburgh Festival Fringe and as a scriptwriter and performer on The Frost Report. In the late 1960s, he co-founded Monty Python, the comedy troupe responsible for the sketch show Monty Python's Flying Circus and the four Monty Python films: And Now for Something Completely Different, Monty Python and the Holy Grail, Life of Brian and The Meaning of Life.

In the mid-1970s, Cleese and his first wife, Connie Booth, co-wrote and starred in the British sitcom Fawlty Towers. Later, he co-starred with Kevin Kline, Jamie Lee Curtis and former Python colleague Michael Palin in A Fish Called Wanda and Fierce Creatures, both of which he also wrote. He also starred in Clockwise, and has appeared in many other films, including two James Bond films as Q, two Harry Potter films, and the last three Shrek films.

With Yes Minister writer Antony Jay he co-founded Video Arts, a production company making entertaining training films. In 1976, Cleese co-founded The Secret Policeman's Ball benefit shows to raise funds for the human rights organisation Amnesty International.

Terry Fox

Terrance Stanley "Terry" Fox CC OD (July 28, 1958 – June 28, 1981) was a Canadian athlete, humanitarian, and cancer research activist. In 1980, with one leg having been amputated, he embarked on a cross-Canada run to raise money and awareness for cancer research. Although the spread of his cancer eventually forced him to end his quest after 143 days and 5,373 kilometres (3,339 mi), and ultimately cost him his life, his efforts resulted in a lasting, worldwide legacy. The annual Terry Fox Run, first held in 1981, has grown to involve millions of participants in over 60 countries and is now the world's largest one-day fundraiser for cancer research; over C$650 million has been raised in his name.

Fox was a distance runner and basketball player for his Port Coquitlam, British Columbia, high school and Simon Fraser University. His right leg was amputated in 1977 after he was diagnosed with osteosarcoma, though he continued to run using an artificial leg. He also played wheelchair basketball in Vancouver, winning three national championships.
