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
The products built in the factories of G.M., Ford and Chrysler are some of the greatest weapons of mass destruction responsible for global warming and the melting of our polar icecaps. Michael Moore
Three things about water affect almost all of cooking. First are the hydrogen bonds, which is why it has an incredibly high boiling point. Another is that it's a polar molecule, so that it dissolves a lot of things, and there are things that won't mix with it. And then there's how much energy it takes to heat water. Nathan Myhrvold
We'll all die out eventually. Humans will be gone. And all I'm saying is, when people worry about polar bears disappearing or whatever, it's like, 'Well that's life, things will come and go, we'll find new species.' Karl Pilkington
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
