    Chemical Detection of Artificial Transmutation of Elements (1933)
    [s.l.] : Nature Publishing Group
    Nature 131 (1933), S. 652-653 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IF detection of elements originating from artificial transmutation can be attained by chemical methods, not only will this mean a desirable checking of physical observations, but also new results may thereby be obtained. For physical means of discerning the transmutation of elements—whether by ...

    A Tribute to Frederick Soddy (1957)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THE first International Conference on Radio-isotopes in Scientific Research seems an appropriate occasion upon which to consider our debt to Frederick Soddy. The duty to clarify his picture is specially incumbent on us, as it is the tragedy of his life that members of the younger generation may ...

    Avogadro's Number and Loschmidt's Number (1957)

    Notes: [Auszug] The reason for Maxwell's choice seems to have been that he did not claim to communicate anything fundamentally new, but only to discuss a line of reasoning which Loschmidt had published eight years earlier in the Proceedings of the Vienna Academy2. Using Maxwell's own words3, he "followed the track ...

    Production by Cosmic Rays of Helium-3 in Meteorites (1953)
    [s.l.] : Nature Publishing Group
    Nature 172 (1953), S. 200-201 
    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] These results were considered as proving the cosmic ray origin, in the meteorites richest in helium, of the helrum-3 and most of the helium-4 ; but various questions concerning the mechanism of the helium formation by cosmic rays and the relative amounts of the two helium isotopes thus created ...

    Origin and Age of Meteorites (1955)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] We should like to put on record that we agree with Prof. Urey that there are difficulties in the interpretation of our results ; but that we do not think that his statements prove that our arguments, leading to an age of no more than a few hundred million years, are incorrect. We are not convinced ...

    Cosmic-Ray Production of Helium in Meteorites and their Ages (1953)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IT has recently been proved that a major part of the helium found in iron meteorites is due to the influence of cosmic rays1. This interaction should produce helium-3, helium-4 and tritium (see, for example, ref. 2), and the tritium will have decayed in geological time to helium-3. Helium-3 has ...

    Notes: [Auszug] We have tried to simplify, and at the same time to increase the accuracy of these experiments by a radiochemical technique. The use of radioactive mirrors in free radical studies is not new. Leighton and Mortensen2 employed invisible mirrors of radium D and E to detect very low concentrations of ...

    Notes: [Auszug] IN a previous article1 analyses of upper air samples obtained from 52-66-5 km. height by means of V2 and Aerobee rockets were described, and it was shown that in all cases the composition of the samples was nearly the same as at ground-level, with respect to the ratio of helium, neon and argon to ...

    Notes: [Auszug] While it is generally known that the rocks of the earth's surface belong to very different geological periods, there always was, and still is, a tendency among scientific men to picture the formation of the three main layers (core, mantle and crust) of any terrestrial planet as the result of a ...

    Notes: [Auszug] ONE of the tributes paid by the Government and men of science of the U.S.S.R. to the memory of Mendeloeff on the occasion of the centenary of his birth1 was the publication of his "Collected Works". It;;contains all the different tables of the Periodic System designed by Mendeloeff at various ...
