The Rosicrucian Mysteries An Elementary Exposition of Their Secret Teachings You must remember that there has been a precession of the equinoxes since the time of Atlantis, with a consequent shift in the earth's axis. Astounding Stories of Super-Science, May, 1930 This angle of tilt may be assumed to be constant, for I won't bother with the precessions, nutations and other minor movements considered in accurate computations. The Solar Magnet When the precession was finished, the rim of the wheel would be aligned, still with the sun, but also with Project Hot Rod which had been to their south. Where I Wasn't Going All such disturbances as precession, aberration, nutation, refraction, and the like, would affect them both equally, and could thus be eliminated. Pioneers of Science For that purpose he generally uses the measure provided by the sun's precession: Each year the sun crosses the earth's equator about the twenty-first of March. The Rosicrucian Mysteries An Elementary Exposition of Their Secret Teachings This is due to what is known as "precession;" a slow movement of the axis upon which the earth rotates.

A Popular History of Astronomy During the Nineteenth Century Fourth Edition It is as much outside 97 our control as the precession of the equinoxes. Waiting for Daylight Hipparchus had, by most sagacious interpretation of certain observations of his, discovered a remarkable phenomenon called the precession of the equinoxes. Pioneers of Science We have thus narrowed very closely the search for the cause of the "precession." The Story of the Heavens Dr. Pratt insists on another of Walsh's notions, namely, that the precession of the equinoxes is caused by the motion of the solar system round a distant central sun. A Budget of Paradoxes, Volume II His argument was, that if it were a mere shell filled with liquid, precession and nutation would be much larger than they are observed to be.

Peter the Great A time will come as certainly as the precession of the equinoxes, when the literary method of historical research will be laid aside as out of date, in the case of all original work. The Story of Atlantis and the Lost Lemuria This effect is produced by the attraction of the sun, moon, and planets upon the spheroidal figure of the earth; the luni-solar precession is the joint effect of the sun and moon only. The Sailor's Word-Book An Alphabetical Digest of Nautical Terms, including Some More Especially Military and Scientific, but Useful to Seamen; as well as Archaisms of Early Voyagers, etc. That is to say, the precession of the equinoxes is seen to be dependent on, and caused by, a slow conical movement of the earth's axis. Pioneers of Science But when we come to that particular effect of attraction which is competent to produce precession, we find that the law by which the efficiency of the attracting body is computed assumes a different form.
