Superconducting Magnets: Materials and Technology, discovery in 1961 that Nb Sn was still superconducting at 90 kilo oersteds. to catch the imagination of the scientific community and begin the modern era. The Nb Sn compound had been reported by Matthias seven years earlier., but the relation between its high critical temperature and such a high critical field was not anticipated.

The Use of Magnetic-Reversal Time Lines in Stratigraphic Analysis: A Case Study in Measuring Variabiinsic lateral fluctuation, or nonuniformity, of sedimentation during early Chinji time averages 28%; vertical fluctuation, or unsteadiness of sedimentation, averages 41%. These fluctuations in sediment accumulation from place to place and from time to time characterize the fluvial system operating over the Potwar Plateau during Miocene time.
