摘要:
Jesuits have had ah interest in observing and explaining geophysical phenomena since this religious order, the Society of Jesus, was founded by Ignatius of Loyola in 1540. Three principal factors contributed to this interest: their educational work in colleges and universities, their missionary endeavors to remote lands where they observed interesting and often as yet undocumented natural phenomena, and a network of communication that brought research of other Jesuits readily to their awareness.One of the first and most important Jesuit colleges was the Roman College (today the Gregorian University) founded in 1551 in Rome, which served as a model for many other universities throughout the world. By 1572, Christopher Clavius (1537–1612), professor of mathematics at the Roman College, had already initiated an important tradition of Jesuit research by emphasizing applied mathematics and insisting on the need of serious study of mathematics in the program of studies in the humanities. In 1547 he directed a publication of Euclid's work with commentaries, and published several treatises on mathematics, includingArithmetica Practica[1585],Gnomonicae[1581], andGeometrica Practica[1606]. Clavius was also a Copernican and supported his friend Galileo when he announced the discovery of the satellites of Jupite

摘要:
Two new data sets from the U.S. Navy's Geodetic Satellite (Geosat) have been produced by the National Oceanic and Atmospheric Administration's (NOAA's) National Ocean Service. Both were derived principally from classified data collected during the 18‐month geodetic mission (April 1985–September 1986). Designed and built by the Johns Hopkins University Applied Physics Laboratory, the Geosat radar altimeter measured global sea level with a precision of 3 cm.The first data set consists of approximately 44‐million crossover differences (sea‐level differences at ground track intersections). These include the initial 18‐month period and the first year of the subsequent exact repeat mission, enabling computation of the continuous 30‐month sea level time series spanning the two missions. Thirty‐six 6250‐bpi magnetic tapes organized in 18 ocean regions document the Geosat crosso

摘要:
Another round of applause for Cynthia Bravo, director of Member Programs, who retired from AGU on April 2. She was awarded a plaque from the Executive Committee “in appreciation of your devotion and friendship, your imagination and humor, and your championship of AGU members for more than 30 years; we salute you and thank you.” AGU President Brent Dalrymple presented the award to Cynthia at a staff luncheon on March 13.Cynthia began her AGU career in 1960. In the letter of notification of her appointment to this position, A. Nelson Sayre, General Secretary, said “The position is a permanent position, but we point out that even beyond the period of probation, permanency in the position depends on continued high performance of your duties, and includes punctuality and regularity in your attendance in the of
