Review of studies of trapped radiation with satellite-borne apparatus

Conclusions Experimental studies of the radiation zones have been subject to the same imperfections as most other experimental physics, with some extra problems because of the features peculiar to rocket and satellite work. We consider that the theoretical physicists must review the existing knowledge, and suggest specific experiments which would be of particular significance. The theoretical studies of radiation-zone phenomena are so new that the theoretician can start essentially afresh, without being fettered by theories based more on longevity than veracity. We trust that this critical review of experimental work may be of value in such efforts.The following quotation from Maritain(1959) is so apt to this paper that it will serve as a conclusion:The intellect ... is no longer interested in anything but the invention of apparatus to capture phenomena — conceptual nets that give the mind a certain practical dominion over nature, coupled with a deceptive understanding of it; ... by advancing in this fashion, not by linking new truths to already acquired truths, but by substituting new apparatus for outmoded apparatus; by handling things without under standing them; by gaining ground against the real bit by bit, patiently, through victories that are always piecemeal and provisory — by acquiring a secret taste for the matter with which it conspires — thus has the modern intellect developed within this lower order of demiurgy a kind of manifold and marvellously specialized touch as well as wonderful instincts for the chase.
