The name octant derives from the Latin octans meaning eighth part of a circle, because the instrument's arc is one eighth of a circle.. Reflecting quadrant derives from the instrument using mirrors to reflect the path of light to the observer and, in doing so, doubles the angle measured.
A beam compass is an instrument, with a wooden or brass beam and sliding sockets, cursors or trammels, for drawing and dividing circles larger than those made by a regular pair of compasses. [2] Scribe-compasses [3] is an instrument used by carpenters and other tradesmen. Some compasses can be used to draw circles, bisect angles and, in this ...
Having a constant diameter, measured at varying angles around the shape, is often considered to be a simple measurement of roundness.This is misleading. [3]Although constant diameter is a necessary condition for roundness, it is not a sufficient condition for roundness: shapes exist that have constant diameter but are far from round.
His development preceded the sextant and was motivated by the need to create a superior surveying instrument. [3] The reflecting circle is a complete circular instrument graduated to 720° (to measure distances between heavenly bodies, there is no need to read an angle greater than 180°, since the minimum distance will always be less than 180°).
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
The radical axis of one pencil consists of the centers of the circles of the other pencil. If one pencil is of elliptic type, the other is of hyperbolic type and vice versa. [13] The radical axis of any pencil of circles, interpreted as an infinite-radius circle, belongs to the pencil.
There is only one unimorphic planar (as opposed to linear) system available on a lead instrument at this time, and that is the system used for organizing the Array mbira. Because the Array system is isomorphic, any given chord, scale, or song, no matter how complex, can be played in any one of the 12 keys immediately after the player learns to ...
