    Notes: [Auszug] FOR the second time within a period of thirty years, science in Germany is struggling for its existence; but the problems of to-day are different from those of 1918, and so are the ways and means by which a solution is being attempted. When, after the First World War, Germany had collapsed, the ...

    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] 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 ...

    Notes: [Auszug] AT a conference held at Oxford in September 1936 the need for a chemical method of determining atmospheric ozone, and the objections against those applied so far, were discussed1. Two years later a procedure was described which avoided the earlier drawbacks: by condensing ozone on cooled silica gel ...

    Notes: [Auszug] FOR various problems in meteorology and physics, it is of importance to know the composition of the earth's atmosphere at all heights. The most direct approach, namely, chemical analysis by laboratoryxnethods, depends on our ability to obtain the samples; the few stratosphere nights by manned ...
