Work
Robert Norman is noted for The Newe Attractive, a pamphlet published in 1581 describing the lodestone (magnet) and practical aspects of navigation. More importantly, it included Norman's discovery of magnetic dip, the incline at an angle from the horizon by a compass needle. This effect is caused by the Earth's magnetic field not running parallel to the planet's surface. Norman demonstrated magnetic dip by creating a compass needle that pivoted on a horizontal axis. The needle tilted at a steep angle relative to the horizon line.
Magnetic inclination and local variations were known before Robert Norman, but his pamphlet had a greater influence than the earlier work.
The crater Norman on the Moon is named in his honour.

Famous quotes containing the word work:
“I am from time to time congratulating myself on my general want of success as a lecturer; apparent want of success, but is it not a real triumph? I do my work clean as I go along, and they will not be likely to want me anywhere again. So there is no danger of my repeating myself, and getting to a barrel of sermons, which you must upset, and begin again with.”
—Henry David Thoreau (1817–1862)
