Compass
A compass is a navigational instrument that measures directions in a frame of reference that is stationary relative to the surface of the earth. The frame of reference defines the four cardinal directions (or points) – north, south, east, and west. Intermediate directions are also defined. Usually, a diagram called a compass rose, which shows the directions (with their names usually abbreviated to initials), is marked on the compass. When the compass is in use, the rose is aligned with the real directions in the frame of reference, so, for example, the "N" mark on the rose really points to the north. Frequently, in addition to the rose or sometimes instead of it, angle markings in degrees are shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation.

Famous quotes containing the word compass:
“It is cruel for you to leave your daughter, so full of hope and resolve, to suffer the humiliations of disfranchisement she already feels so keenly, and which she will find more and more galling as she grows into the stronger and grander woman she is sure to be. If it were your son who for any cause was denied his right to have his opinion counted, you would compass sea and land to lift the ban from him.”
—Susan B. Anthony (1820–1906)
“To “give style” to one’s character—a rare and noble art! Those practice it who compass all that their natures present as strengths and weaknesses and then fit them into an artistic plan until every one appears as art and reason and even weakness enchants the eye.”
—Friedrich Nietzsche (1844–1900)
“It is the star to every wand’ring bark,
Whose worth’s unknown, although his height be taken.
Love’s not Time’s fool, though rosy lips and cheeks
Within his bending sickle’s compass come;
Love alters not with his brief hours and weeks,
But bears it out even to the edge of doom.”
—William Shakespeare (1564–1616)
