Page 395 - The squares of the periodic times of the planets are proportional to the cubes of their mean distances from the Sun.
Page 29 - ... that the mean longitude of the first satellite, minus three times that of the second, plus twice that of the third, is always equal to two right angles.
Page 22 - That day, as other solemn days, they spent In song and dance about the sacred hill ; Mystical dance, which yonder starry sphere Of planets, and of fix'd, in all her wheels Resembles nearest, mazes intricate, Eccentric, intervolved, yet regular Then most, when most irregular they seem ; And in their motions harmony divine So smooths her charming tones, that God's own ear Listens delighted.
Page 398 - The circumference of every circle is supposed to be divided into 360 equal parts called degrees, and each degree into 60 equal parts called minutes, and each minute into 60 equal parts called seconds, and these into thirds, fourths, &c.
Page 19 - But, in the midst of all these vicissitudes, the length of the major axes and the mean motions of the planets remain permanently independent of secular changes. They are so connected by Kepler's law, of the squares of the periodic times being proportional to the cubes of the mean distances of the planets from the sun, that one cannot vary without affecting the other.
Page 421 - Whatever the reflecting surface may be, and however obliquely the light may fall upon it, the angle of reflection is always equal to the angle of incidence.
Page 88 - ... there is a meridian about 30° eastward of the moon, where it is always high water both in the hemisphere where the moon is and in that which is opposite. On the west side of this circle the tide is flowing, on the east it is ebbing, and on every part of the meridian at 90° distant it is low water.
Page 296 - The spark taken in the same manner from zinc, cadmium, tin, bismuth, and lead, in the melted state, gives similar results ; but the number, position, and colours of the lines vary in each case. The appearances are so different that, by this mode of examination, the metals may be readily distinguished from each other.
Page 289 - ... reached the horizon. In the night the sea became nearly as luminous as before, but on the fifth night the appearance entirely ceased. " Captain Bonnycastle does not think it proceeded from...
