Of or pertaining to one of the poles of the earth, or of a sphere; situated near, or proceeding from, one of the poles; as, polar regions; polar seas; polar winds.
Of or pertaining to the magnetic pole, or to the point to which the magnetic needle is directed.
Pertaining to, reckoned from, or having a common radiating point; as, polar coordinates.
The right line drawn through the two points of contact of the two tangents drawn from a given point to a given conic section. The given point is called the pole of the line. If the given point lies within the curve so that the two tangents become imaginary, there is still a real polar line which does not meet the curve, but which possesses other properties of the polar. Thus the focus and directrix are pole and polar. There are also poles and polar curves to curves of higher degree than the second, and poles and polar planes to surfaces of the second degree.
He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn towards it. Confucius
When we save the rain forest, the polar bear, and Al Gore, we should party so hard that Canada calls the cops on us for noise. Paula Poundstone
At the heart of every really good Christmas movie is the threat, I suppose, to Christmas. Something is wrong with Christmas, in all of these movies. In 'The Polar Express,' there's a kid that doesn't really believe, and that's the threat to Christmas. In 'Santa Claus: The Movie,' jealousy and greed are threatening to overrun his Christmas. James McAvoy
For humans, the Arctic is a harshly inhospitable place, but the conditions there are precisely what polar bears require to survive - and thrive. 'Harsh' to us is 'home' for them. Take away the ice and snow, increase the temperature by even a little, and the realm that makes their lives possible literally melts away. Sylvia Earle
Rising sea levels, severe draughts, the melting of the polar caps, the more frequent and devastating natural disasters all raise demand for humanitarian assistance and disaster relief. Leon Panetta
