Modern Depictions
The contemporary compass rose appears as two rings, one smaller and set inside the other. The outside ring denotes true cardinal directions while the smaller inside ring denotes magnetic cardinal directions. True north refers to the geographical location of the north pole while magnetic north refers to the direction towards which the north pole of a magnetic object (as found in a compass) will point. The angular difference between true and magnetic north is called variation, which varies depending on location. The angular difference between magnetic heading and compass heading is called deviation which varies by vessel and its heading.

Famous quotes containing the words modern and/or depictions:
“Whosoever, in writing a modern history, shall follow truth too near the heels, it may haply strike out his teeth.”
—Sir Walter Raleigh (1552–1618)
“Surely, of all creatures we eat, we are most brutal to snails. Helix optera is dug out of the earth where he has been peacefully enjoying his summer sleep, cracked like an egg, and eaten raw, presumably alive. Or boiled in oil. Or roasted in the hot ashes of a wood fire.... If God is a snail, Bosch’s depictions of Hell are going to look like a vicarage tea-party.”
—Angela Carter (1940–1992)
