Book Description
Excerpt from The Astrophysical Journal, 1901, Vol. 14 Let.us consider two arcs which are alike except that a larger current runs through the first than through the second. Since the secondary causes of radiation go hand in hand with the electrical cause, we may expect the first arc to have a spectrum which is uniformly brighter from one end to the other than that of the second arc. With the exception of a slight variation, probably due to conduction losses, this is just what is always observed, and confirms the secondary character of the Chemical and thermal causes of radiation. If these causes were not dependent upon the electrical causes, we might possibly get an arc which would give only a flame spectrum, or an arc which would give only a Spark spectrum. Let us now suppose that we run the same current through both the similar arcs, and suppose that in some way we reduce the chemical action going on in the second arc. What differ ence may we expect to observe in them? About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Astrophysical Journal, 1901, Vol. 13 In discussing periodic phenomena in which the times of recurrence of a given phase are subject to irregularities two hypotheses may be made. One is that underlying the periodic phenomena which we observe, there is a primary cause going through a perfectly uniform period; but that, on the action of this cause are superseded irregular actions which may delay or accelerate the occurrence of a phase without affecting the primary cause. When this is the case we shall have a series of perfectly equidistant normal epochs for the recurrences of the same phase, and the observed deviations from these epochs will be in the nature of separate and independent accidental errors. That is to say, if P be the true value of the normal period then, at the end of n periods, however great n may be, the time of occurrence of the phase will differ from n P only by a small quantity ±e indicating the irregularity in the general mean. This value of e will be the same, no matter how great n may be. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Astrophysical Journal, 1895, Vol. 34 In 189 5 Percival lewisi at Johns Hopkins measured the wave lengths of thirteen infra-red spectral lines whose wave-lengths lay between Ca 7664 and Th a.u., with an actual accuracy of about one a.u.; an accuracy hitherto unattained and not equaled in the subsequent important researches of Lehmann,2 Bergmann,3 and Moll.4 In two very noteworthy contributions in i9os and 1909 Paschen5 very materially extended the work of Lewis, attaining an accuracy in case of sources of constant intensity of a few tenths au. And a maximum wave-length of approximately au. This latter limit was again extended the following year to au. By the same observer. Many of the lines found will serve as standards of wave-length in the infra-red, on account of their intensity and sharpness and the accuracy with which they were measured; While the results in general have fur nished much needed data for the establishment of series laws and especially the combination principle of Ritz.

Excerpt from The Astrophysical Journal, 1899, Vol. 10 The value adopted for a, the semi - axis major of the Earth's orbit, is based upon as the solar parallax; an error of in this constant corresponds to a maximum error of kilometers per second in the correction to an observed velocity. Had a different parallax been employed the only effect upon these tables would have been the addition of a constant to each log b. For I', the Sun's longitude at perigee, the round value 281° 20' has been employed; this is about its value for 1950, referred however to the equinox of 1900.
