ABSTRACT
Frontiers of science are usually considered as those areas where the boundares of human knowledge are being pushed most vigorousl into the unknown. These are the intemal frontiers. But no less important are the external frontiers. Those bordering on the federal govermment, on education, on private industry and on intemational affairs and the developing world are among the most critical and demanding. Some of the outstanding problems facing science, and scientists in these extemal interactions, are discussed within the context of our changing national and international priorities.
ABSTRACT
From massive quarks deep in the hearts of atomic nuclei to the catastrophic collapse of giant stars in the farthest reaches of the universe, from the partial realization of Einstein's dream of a unified theory of the forces of nature to the most practical applications in technology, medicine, and throughout contemporary society, physics continues to have a profound impact on man's view of the universe and on the quality of life. The author argues that the past few years, in terms of new discoveries, new insight-and the new questions-have been among the most productive in the history of the field and puts into context his selection of some of the most important new developments in this fundamental science.
