Joke of the Week: Love Quotes

I was nauseous and tingly all over. I was either in love or I had smallpox. - Woody Allen

Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience. -Samuel Johnson

To love is to suffer. To avoid suffering one must not love. But then one suffers from not loving. Therefore to love is to suffer, not to love is to suffer. To suffer is to suffer. To be happy is to love. To be happy then is to suffer. But suffering makes one unhappy. Therefore, to be unhappy one must love, or love to suffer, or suffer from too much happiness. I hope you're getting this down. -Woody Allen

The great question... which I have not been able to answer... is, "What... does a woman want?" – Freud Love is grand; divorce is a hundred grand. - Anonymous

An archeologist is the best husband any woman can have; the older she gets, the more interested he is in her. -Agatha Christie

Gravitation cannot be held responsible for people falling in love. - Albert Einstein

You can't put a price tag on love, but you can on all its accessories. - Melanie Clark



Problem: Surveying Astronomy: The Equation of Time

An hour measured by the apparent motion of the true sun, which is sundial time, varies with the time of year. An hour measured by the imaginary mean sun is constant throughout the year. Which of the following reasons account for this effect?

(A) The orbit of the earth around the sun is elliptical. Therefore, the apparent motion of the true sun is  more rapid when the earth is closer to the sun and slower when the earth is farther away.
(B) The apparent motion of the true sun is along the ecliptic and the motion of the imagined mean sun is along the celestial equator. Therefore, the mean sun moves steadily in terms of right ascension, which the true sun does not.
(C) The tidal forces of the moon and other planets of the solar system cause the rate of the rotation of the earth on its axis to vary significantly during the year. This variation causes the apparent motion of the true sun to vary.
(D) Both A and B are true.
