    Notes: [Auszug] IN discussing the significance of the two planet-like bodies which are now supposed to revolve around 61 Cygni and 70 Ophiuchi, Mr. Sen writes1 that “we find that there can be at most two planetary systems in the galactic system, on Jeans's theory”. If the true number were two, ...

    Notes: [Auszug] As neither Sir Oliver Lodge (NATURE, March 17) nor Mr. Bartrum (March 31) appears to find my explanation very satisfying, may I further explain as briefly as may be how and why I consider that the Majorana experiments add valuable new knowledge to that previously yielded by the classical ...

    Notes: [Auszug] DR. SHAPLEY makes the suggestion (NATURE, March 13) that known supplies of energy become adequate to maintain stellar and solar radiation through astronomical time if we can suppose that radiation is propagated only from matter to matter, and is not radiated equally in all directions. In brief, ...

    Notes: [Auszug] THE equation of motion of a body which is losing mass by the emission of radiation is ... where m is the momentary mass of the body and F the applied force. The simplest justification for this equation is found in the principle of relativity, which requires that v shall be constant when F = ...

    Notes: [Auszug] I AM sorry that the only reply I can make to Prof. Eddington's remarks in NATURE of July 5 is that his amended equation seems to me neither to be true nor to lead to his supposed laws. But perhaps I may be permitted to offer a few remarks on the general problem. Suggested sources of ...

    Notes: [Auszug] MANY besides astronomers will have received pleasure from reading Prof. Eddington's lecture which appears in NATURE of May 1, but I doubt whether mathematicians, physicists or chemists will be prepared to accept his proposed means of escape from the difficulties which beset his theories. He ...

    Notes: [Auszug] A DEFINITE answer to Sir Oliver Lodge's interesting question is still, I fear, quite outside the range of exact dynamical analysis. We know that the formation of a binary star begins with a cataclysm, we know the stage of the star's evolution at which this cataclysm occurs and the direction in ...

    Notes: [Auszug] DOES not Prof. Lindemann's theory of spiral nebulæ (discussed by Sir Oliver Lodge in NATURE of May 26, p. 702) fail through disregarding the absorption or reflection of radiation which must necessarily accompany any mechanical action of light-pressure? Prof. Lindemann's typical nebula has a ...

    Notes: [Auszug] WITHIN the mesh of our local star-system are nebulæ of irregular shape, such as the Orion nebula, which are of only slight cosmogonic interest. Far beyond the confines of this local star-system lie the great nebulæ of regular shapes, spiral, elliptic, circular, etc., each of which is comparable ...

    Notes: [Auszug] THE frequency ν of radiation can be deduced from its absorption μ by means of the well-known formula of Klein and Nishina,1 which can be put in the form ... This gives frequencies which agree well with experiment up to the frequencies of the hardest γ-rays; beyond this it is ...
