Page 37 - All the interior angles of any rectilineal figure, together with four right angles, are equal to twice as many right angles as the figure has sides.
Page 129 - The mean solar day is divided into 24 hours, each hour into 60 minutes, and each minute into 60 seconds.
Page 129 - An apparent solar day is the interval between two successive transits of the sun's centre across the meridian of any place.
Page 122 - As the planet moves round the sun, its radius-vector (or the line joining it to the sun) passes over equal areas in equal times. To explain these laws, let PA (Fig. 20) be the ellipse in which the planet moves. Then the sun will not be in the cenFio.

Page 204 - ... is equal to the probable error of a single observation divided by the square root of the number of observations. The probable error of the mean, hence, decreases as Vw increases.
