...years of the 14th century until the Reformation and later a native style known as Perpendicular Gothic was developed. This is named after the perpendicular lines of the mullions in the windows (which were enlarged until they filled all the available space in the walls), but the style includes much more than that, e.g. flat lead roofs hidden behind battlements and pinnacles, long ranges of clerestory windows, and carved wooden roofs. See John Harvey , The Perpendicular Style, 1330–1485 (1978). In Ireland, Scotland, and Wales there are far fewer...

(in the plane)The distance from the point P to the line l is the shortest distance between P and a point on l. It is equal to |PN|, where N is the point on l such that the line PN is perpendicular to ...

(in 3-dimensional space)Let l 1 and l 2 be lines in space that do not intersect. There are two cases. If l 1 and l 2 are parallel, the distance between the two lines is the length of any line segment ...

The distance between a geophone, or the centre of a geophone group, and the shot position. In-line offset is the displacement within the line of the spread; perpendicular (normal) offset is the ...

The shortest perpendicular distance between a force's line of action and an axis of rotation (e.g. a pivot). In a lever, the moment arm of the force is often referred to as the force arm and that of ...

The component of a star's velocity that is perpendicular to our line of sight (i.e. in the tangent plane); also known as transverse velocity. A star's tangential velocity can be computed from its ...

The perpendicular distance from the axis of a lever to the point of resistance in the lever.

For a lever, the ratio of the perpendicular distance of the line of action of the effort from the fulcrum, to the perpendicular distance of the line of action of the resistance or load from the ...

A simple machine consisting of a rigid bar pivoted about a fulcrum. The mechanical advantage or force ratio of a lever (the ratio of load to effort) is equal to the ratio of the perpendicular ...

Spiral galaxies are observed to rotate about an axis perpendicular to their disk. The rotation curves of spiral galaxies show how the rotation speed varies with distance from the centre ...

Being the same distance from one or more points or objects. The perpendicular bisector of the line segment AB is the set of points equidistant from A and B.The set of points equidistant from a fixed ...

A result in electromagnetism that states that the magnetic flux density B of a magnetic field produced by a current I in a long straight conductor is directly proportional to I and inversely ...

A measure of the ability of matter to reduce the kinetic energy of a particle passing through it. The linear stopping power, −dE/dx, is energy loss of a particle per unit distance. The mass stopping ...

A method of interpreting seismic refraction profiles over irregular layers whose slope angles do not exceed 10°. It uses both forward and reverse shooting to obtain matched time-distance graphs. The ...

An imaginary ellipsoid (a solid body formed when an ellipse is rotated about an axis) that is used when expressing the height of the geoid as the perpendicular distance between the geoid and the ...

In remote sensing, the colour of each pixel. Pixel colour is dependent on three parameters: the intensity, which is the brightness of the colour; the saturation, which is the perpendicular distance ...

In elementary work, a cone usually consists of a circle as base, a vertex lying directly above the centre of the circle, and the curved surface formed by the line segments joining the vertex to the ...

One of two patterns of movement, described by the Austrian zoologist Karl von Frisch (1886–1982) in a series of publications from 1924 onwards, through which a female honey-bee communicates to other ...
