Briefly described are the history, the educational and technological development, and the educational and technological needs of the nation of Niger. (SL)

Presents a new and annotated translation of Einstein's first paper on relativity plus remarks on the content of the paper and its significance in science history. (MLH)

Discusses the historical background of the 1887 Michelson-Morley experiment to detect the earth's motion through the aether. (MLH)

This paper is linked to the theme History and Philosophy of Science. The Evolution and creation science controversy is now in the general public's arena and poses a challenge for school science. The paper begins by briefly describing the current situation concerning this issue in Australia and the United States of America. In the subject Biology,…

A chronology of the development of time measurement is outlined. Measurement techniques are described and improvements in standards sequenced, persons who have contributed to the development of time measurement noted, as well as, various time measuring apparatus illustrated. (JP)

The relationship between the two concepts (evolution, religion) from an historical and social view is discussed. The concepts are seen to respond differently to the various needs of society, with considerable conflict between them in areas which involve the justification of religious beliefs. (Author/EB)

Analysis of the citations in the papers written by physicists suggested that relatively few scientists produce work that becomes the base for future discoveries in physics. This is contrary to the hypothesis of Ortega that large numbers of average scientists contribute substantially to the advance of science through their work. (AL)

A presentation of the "Father of Organic Chemistry" whose fame rests on three aspects: (1) his original research; (2) his teaching ability and the legacy he left his gifted pupils; and (3) his interest and efforts in teaching to the layman. (DF)

Problems involving infinity and paradoxes are included in a discussion of how students can be exposed to the human element of mathematics. (DT)

Reviews ideas and evidence bearing on the origin of life. Shows that evidence to support modifications of Oparin's theories of the origin of biological constituents from inorganic materials is accumulating, and that the necessary components are readily obtained from the simple gases found in the universe. (AL)

Describes the structure of the observatory built in India in 1710 and shows the relationship of the scientific and geometric principles involved. (AL)

Alchemy can be used to establish that chemistry was also an art which later changed to science. Courses in alchemy will not only create more interest in science majors but non-science majors as well. The paintings identified in the article can be procured from commercial firms, and discussion lessons planned. (PS)

Dirac's classical conclusions, that the values of e2, M and m are constants and the quantity of G decreases with time. Evoked considerable interest among researchers and traces historical development by which further experimental evidence points out that both e and G are constant values. (PS)
