Page ii - Certain commercial equipment, instruments, or materials are identified in this paper to specify adequately the experimental procedure. Such identification does not imply recommendation or endorsement by the National Institute of Standards and Technology, nor does it imply that the materials or equipment identified are necessarily the best available for the purpose.
Page xi - I often say that when you can measure what you are speaking about and express it in numbers you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.

However, the year's events did not in themselves suggest that a turning point had been reached in North-South relations. Two major UN conferences on development issues were held in the course of 1979: Unctad V in Manila and the UN Conference on Science and Technology for Development (UNCSTD) in Vienna.
Page 297 - CD-ROM: IEEE/IEE ELECTRONIC LIBRARY The IEEE/IEE Electronic Library (IEL) gives researchers full-image access to the publications of both the Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Electrical Engineers (IEE). This complete reference system includes an image database of IEEE/IEE material, including all journals, magazines, standards and conference proceedings published since 1988. The powerful index, a subset of the INSPEC database, allows users to search specifically...
