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:
“Lazybones, sleepin’ in the sun, how you ‘spec’ to get your day’s work done?”
—Johnny Mercer (1909–1976)
“Women are in bondage; their clothes are a great hindrance to their engaging in any business which will make them pecuniarily independent, and since the soul of womanhood never can be queenly and noble so long as it must beg bread for its body, is it not better, even at the expense of a vast deal of annoyance, that they whose lives deserve respect and are greater than their garments should give an example by which woman may more easily work out her own emancipation?”
—Lucy Stone (1818–1893)
“The poet needs a ground in popular tradition on which he may work, and which, again, may restrain his art within the due temperance. It holds him to the people, supplies a foundation for his edifice; and, in furnishing so much work done to his hand, leaves him at leisure, and in full strength for the audacities of his imagination.”
—Ralph Waldo Emerson (1803–1882)
