A circle, in Euclidean geometry, is the set of all points at a fixed distance, called the radius, from a fixed point, the centre. The points can only be those that are part of a conic section; within the set of a plane bisecting a cone. Circles are simple closed curves, dividing the plane into an interior and exterior. Sometimes the word circle is used to mean the interior, with the circle itself called the circumference(C). Usually however, the circumference means the length of the circle, and the interior ...

On the Earth, a circle of latitude or parallel is an imaginary east-west circle that connects all locations with a given latitude. The position on the circle of latitude is given by the longitude. Each is perpendicular to all meridians at the intersection points. Those parallels closer to the poles are smaller than those at or near the Equator. Circles of latitude are based on the rotation of the Earth. Four special ones are based on the relationship with the Earth's orbit arou ...

The earliest recorded crop circle is supposedly depicted in a 17th Century woodcut called the Mowing-Devil. The image depicts a strange creature creating a circular design in a field of corn. The legend suggests that the farmer, disgusted at the wage his mower was demanding for his work, insisted that he would rather have the devil himself perform the task. Proponents of the belief that crop circles are either naturally caused, or are formed by as yet unknown entities, often support their viewpoint with this old tale. It is worth noti ...

In 1991, more than a decade after the phenomena began, two men announced that many crop circles were a hoax of their doing. Doug Bower and Dave Chorley revealed that they had been making crop circles since 1978 using planks, rope, hats and wire as their only tools. Bower and Chorley stated to reporters that a small group of people can stomp down a sizeable area of crop in a single night. "Stomp" does not mean using the feet: simple tools to ...

In Boy Scout terminology, when using a knife or axe, the area within the radius of the arm and blade length combined is called the blood circle or safety circle. This area can be envisioned as a sphere with a person and a sharp instrument at its center. Presumably, anyone within this radius is at risk of being wounded by an accidental slip of the blade. Therefore, it is desirable to ke ...

A closed circle argument is one that is unfalsifiable. Psychoanalytic theory, for example, is held up by the proponents of Karl Popper as an example of an ideology rather than a science. A patient regarded by his psychoanalyst as "in denial" about his sexual orientation may be viewed as confirming he is homosexual simply by denying that he is; and if he has sex with women, he may be accused of trying to buttress his denials. In other words, there is no way the patient could convincingly demonstrate his heterosexuality to his analyst. This is an example of what Popper called a "closed circle". The propositio ...

This page is about the phenomena of crop circles. For information about the music band, please see Crop Circles. Crop circles are areas of cereal or similar crops that have been systematically flattened to form various geometric patterns. The phenomenon itself only entered the public imagination in its current form after the notable appearances in England in the late 1970s. People who study crop circle phenomena sometimes humorously call themselves "cerealogists", after the usually known name for the pseudoscience that studies crop circles: cereology. ...

The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth. This is the parallel of latitude that (in 2000) runs 66° 33' 39" north of the Equator. Everything north of this circle is known as the Arctic, and the zone just to the south of this circle is the Northern Temperate Zone. The Arctic Circle marks the southern extremity of the polar day of the summer solstice in June and the polar night of the winter solstice in December. Within the Arctic Circle, the arctic Sun is above the horizon for at ...

In mathematics, a unit circle is a circle with unit radius, i.e., a circle whose radius is 1. Frequently, especially in trigonometry, "the" unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane. The unit circle is often denoted S1; the generalization to higher dimensions is the unit ball. If (x, y) is a point on the unit circle in the first quadrant, then x and y are the lengths of the legs of a right triangle whose hypotenuse has length 1. Thus, by the Pythagorean theorem, x and ...

The Magic Circle is a British organisation dedicated to magic, and magicians who want to join need to demonstrate their skills to existing members.

The Magic Circle was founded in 1905, after a meeting of twenty three amateur and professional magicians at London's Pinoli's Restaurant. The first official meeting was held at The Green Man public house in Soho, but meetings were later held in a room at St. George's Hall in Langham Place, where David Devant an ...

The Vienna Circle was a group of philosophers and scientists organized in Vienna under Moritz Schlick. They met weekly, for the most part, beginning in 1922 and ending in 1936, when Schlick was shot to death by an irate graduate student, Johann Nelböck. Many members had left Austria during the rise of the Nazi party. The Circle clashed with the Nazi party over its ideological and mysticism-based scientific research. Their approach to philo ...

In music theory, the circle of fifths is an example of a modulatory space. It consists of all 12 notes of the (equally tempered) chromatic scale. Starting on any note and repeatedly ascending by the musical interval of a perfect fifth, one will eventually land on the same note, after reaching all of the other notes: Descending by fifths, and ascending or descending by fourths also works, since motion in one direction by a fourth is equivalent to motion in the opposite direction by a fifth. For this reason the circle o ...
