Página ix - In the northern hemisphere the cyclone rotates in a direction contrary to that in which the hands of a clock move, but in the southern hemisphere the rotation coincides with the movement of the hands.
Página 44 - that every particle of matter in the universe attracts every other particle, with a force whose direction is that of the line joining the two, and whose magnitude is directly as the product of their masses, and inversely as the square of their distances from each other.
Página 40 - ... varies inversely as the square of the planet's distance from the sun. There is a slight error in Nichol's statement that ' by an appropriate choice of an eccentric circular orbit the sun's motion relative to the earth or to any planet,' (or, which is the same thing, any planet's motion relatively to the sun), 'may be very closely approximated to,' on the supposition of uniform velocities.
Página 203 - This world was once a fluid haze of light, Till toward the centre set the starry tides, And eddied into suns, that wheeling cast The planets...
Página iv - To ask or search I blame thee not, for heaven Is as the book of God before thee set, Wherein to read his wondrous works, and learn His seasons, hours, or days, or months, or years.
Página 193 - For they left the way of their ancestors, and worshipped the God of heaven, the God whom they knew: so they cast them out from the face of their gods, and they fled into Mesopotamia, and sojourned there many days.
Página 191 - Carrying through fether in perpetual round Decrees and resolutions of the gods. WORDSWORTH. IN many parts of the East astronomical systems are found which bear obvious traces of a common origin. We find in all the same duodecimal division of the Zodiac ;* the week used as a division of time ; the planets associated in the same order with the days of the week and the hours of the day ;| and other points of resemblance, sufficiently marked to leave little doubt that they are not accidental.
Página iv - But this I do say, and would wish all men to know and lay to heart, that he who discerns nothing but Mechanism in the Universe has in the fatalest way missed the secret of the Universe altogether. That all Godhood should vanish out of men's conception of this Universe seems to me precisely the most brutal error, — I will not disparage Heathenism by calling it a Heathen error, — that men could fall into. It is not true...
Página 75 - Titan and the moon from their respective primaries, must be still farther increased in the proportion of the square of Titan's velocity to the square of the moon's velocity. This could be readily effected from the data given above ; but the calculation will be simplified if we consider that the velocity of a body revolving in a circle varies, directly as the radius of the circle, and inversely as the period of revolution. Thus, to obtain Saturn's mass, the earth's mass must be increased as the cubes...
Página 63 - THERE is not, perhaps, another object in the heavens that presents us with such a variety of extraordinary phenomena as the planet Saturn. A magnificent globe, encompassed by a stupendous double ring, attended by seven satellites, ornamented with equatorial belts, compressed at the poles; turning...
