Σελίδα 37 - Such is the effect produced by the unequal heating of the equatorial parts; or, more correctly, such would be the effect were it not greatly modified by the earth's movement of rotation. As the circumference of the earth is, in round numbers, about 24,000 miles, and since it rotates on its axis, from west to east, once in 24 hours, the equatorial parts must have a motion of 1000 miles per hour; this velocity diminishes rapidly toward each pole, where it is reduced to nothing.
Σελίδα 52 - A circle may be regarded as composed of an infinite number of triangles, the sum of whose bases is the circumference of the circle and whose altitude is the radius of the circle.
