Europe

Europe (ⁱ/ˈjʊərəp/ or /ˈjɜːrəp/) is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the borders of Europe—a concept dating back to classical antiquity—are arbitrary, as the primarily physiographic term "continent" also incorporates cultural and political elements.

Europe is the world's second-smallest continent by surface area, covering about 10,180,000 square kilometres (3,930,000 sq mi) or 2% of the Earth's surface and about 6.8% of its land area. Of Europe's approximately 50 countries, Russia is by far the largest by both area and population, taking up 40% of the continent (although the country has territory in both Europe and Asia), while Vatican City is the smallest. Europe is the third-most populous continent after Asia and Africa, with a population of 739–743 million or about 11% of the world's population. Europe has a climate heavily affected by warm Atlantic currents, tempering winters and enabling warm summers on most of the continent, even on latitudes that have severe climates in North America and Asia. Further from the Atlantic, seasonal differences increase, but the mildness of the climate remains.

Tutor

A tutor is an instructor who gives private lessons. Shadow education is a name for private supplementary tutoring that is offered outside the mainstream education system.

Normally, a tutor will help a student who is struggling in a subject of some sort. Also, a tutor may be provided for a student who wants to learn at home.

In the United States, the term "tutor" is generally associated with one who gives professional instruction (sometimes within a school setting but often independently) in a given topic or field.

British and Irish secondary schools

In English and Irish secondary schools, form tutors are given the responsibilities of a form or class of students in a particular year group (up to 30 students). They usually work in year teams headed by a year leader, year head, or guidance teacher.

Form tutors will provide parents with most of the information about their child's progress and any problems they might be experiencing. Ordinarily, the form tutor is the person who contacts a parent if there is a problem at school; however, the year leader or guidance teacher may contact the parents, since the form tutor has full-time responsibility as a specialist subject teacher.

British English

British English is the English language as spoken and written in Great Britain or, more broadly, throughout the British Isles. Slight regional variations exist in formal, written English in the United Kingdom. For example, the adjective wee is almost exclusively used in parts of Scotland and Northern Ireland, whereas little is predominant elsewhere. Nevertheless, there is a meaningful degree of uniformity in written English within the United Kingdom, and this could be described by the term British English. The forms of spoken English, however, vary considerably more than in most other areas of the world where English is spoken, so a uniform concept of British English is more difficult to apply to the spoken language. According to Tom McArthur in the Oxford Guide to World English, British English shares "all the ambiguities and tensions in the word British and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity."

6, 7, 8

Six in the Seven at Eight, usually called 6, 7, 8, was an Argentine political commentary TV program broadcast by the government-run Channel 7 since 2009. Its name comes from the fact that, when it first started airing, there were five members on the show's panel, and its motto was you are the sixth one (the viewer). Since it was broadcast by Channel 7 at 8 p.m., the name was shortened to "6, 7, 8". In late 2009, the program was moved to 9 p.m., a new segment was added to be aired on Sundays at night, and new guest panelists were invited, making it more than six members. Nevertheless, the show's name remained unchanged.

It was first hosted by María Julia Oliván and a panel which included Orlando Barone, Carla Czudnowsky, Eduardo Cabito Massa Alcántara, Luciano Galende and Sandra Russo, along with a guest analyst who would give their opinions throughout the program. María Julia Oliván announced in an interview for web site Television.com.ar that, on January 28, 2010, should make her last appearance on the program. Her place was occupied by Luciano Galende, and from 2013 onward the host has been Carlos Barragán.

Mathematics

Mathematics (from Greek μάθημα máthēma, “knowledge, study, learning”) is the study of topics such as quantity (numbers),structure,space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.

Mathematicians seek out patterns and use them to formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proof. When mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity for as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.

Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements. Since the pioneering work of Giuseppe Peano (1858–1932), David Hilbert (1862–1943), and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that has continued to the present day.
