80. oldal - RULES to know when the Moveable Feasts and Holy-days begin. TOASTER-DAY (on which the rest depend) is always the First -*-* Sunday after the Full Moon which happens upon, or next after the Twenty-first Day of March ; and if the Full Moon happens upon a Sunday, Easter-Day is the Sunday after.
120. oldal - Resolved, in view of the fact that a large majority of the nations of the world have already adopted systems of standard time...
120. oldal - College, Oxford. It was resolved to accept the invitation of M. JANSSEN to meet at Meudon in September, 1907. Professors SCHUSTER (chairman) and HALE were elected members of the executive committee. It was decided that the central bureau should be at the University of Manchester, and that the computing bureau should be at the University Observatory, Oxford, under the direction of Professor TURNER. Committees were elected to deal with the following four subjects : ( 1 ) standards of wave-length; (2)...
120. oldal - ... interesting contribution is to our general philosophy of nature. Heretofore we have regarded the cosmical processes as forever aggregating matter into larger and still larger bodies, and dissipating energy more and more uniformly. Now we recognize important tendencies for the dispersion of matter.
118. oldal - ... and in maintaining the proposition that the determination of the solar parallax is a problem of geometry and celestial surveying, and that upon the sponsors of the indirect methods lies the onus of showing cause for their disagreement. This opens up an interesting prospect. Suppose that in course...
119. oldal - Again, should further investigation confirm the conclusion that 8 '76 seconds is the only value of the solar parallax which will reconcile the existing theory of the motion of the planet with the observed value of the constant of gravitation, it may be that the contradiction between the direct and the indirect methods will at last enable the dynamical astronomers to lay a finger upon that flaw which exists somewhere or other in the theory and makes it impossible to say at the present time that all...
120. oldal - I suggest that the zodiacal light be hereafter described as a luminosity surrounding the Sun on all sides, of which the boundary is nowhere less than 35° from the Sun, and which is greatly elongated in the direction of the ecliptic.

120. oldal - The spiral theory raises a whole series of new and very difficult questions in celestial mechanics. These are the immediate effects of the tidal forces which are developed by the near approach of two suns, the perturbations of the orbits of matter which has been ejected by one of them under a variety of conditions, and the secular evolution of the orbits of this ejected material. A large amount of labor will be required to carry the discussion of these questions to a successful conclusion. The spiral...
