    Notes: [Auszug] It is clear from Huygens's principle that the spherical wave issuing from a sufficiently small aperture will be independent of the angle of incidence {except for cosine law variation) and of the convergence of the incident wave. Thus a photometer consisting of a multiplier cell, and a small ...

    Nature 202 (1964), S. 641-646 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] RECENT developments in aviation have led to the requirement for a pilot to fly 'on instruments' while observing the forward view. This amounts to performing concurrent tasks based on information available in visual fields which are separated in position and in which the information may take ...
