López M.A. Lombardi Física, Astronomía y Matemáticas time time Astrometry Astrometry Time and its measurement belong to the most fundamental core of physics, and man y scientific and technological advances are directly or indirectly related to time measurements. Timekeeping is essen tial to everyday life, and thus is the most measured physical quantity in modern societies. Time can a lso be measured with less uncertainty and more resolution than any other physical quantity. The measurem ent of time is of the utmost importance for many applications, including: global navigation satellite systems, communications networks, electric power generation, astronomy, electronic commerce, and national defense and secur ity. This paper discusses how time is kept, coordinated, and disseminated in the Americas. 2015 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57150514002 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.46 |
