Σελίδα 20 - Newton generalized the law of attraction into a statement that every particle of matter in the universe attracts every other particle with a force which varies directly as the product of their masses and inversely as the square of the distance between them; and he thence deduced the law of attraction for spherical shells of constant density.
Σελίδα 37 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Σελίδα 313 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another.
Σελίδα 415 - All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again.
Σελίδα 356 - The Ram, the Bull, the heavenly Twins, And next the Crab the Lion shines, The Virgin and the Scales ; The Scorpion, Archer and He-goat, The Man that holds the watering-pot And Fish with glittering tails.
Σελίδα 317 - The zenith distance of a body is its angular distance from the zenith, measured on the vertical circle passing through the body from 0° to 90°. It is the complement of the altitude.
Σελίδα 258 - When there is not enough of clouds and wind to afford this degree of protection, dew begins to form, and by preventing the temperature of any leaf or flower from sinking below the dew-point, saves them all from destruction, unless, as when hoar-frost appears, the dew-point itself is below the freezing-point.
