xx Preface Meet the Authors Konrad B Krauskopf was born and raised in Madison Wisconsin and earned a B S in chemistry from the University of Wisconsin in 1931 He then earned a Ph D in chemistry at the University of California in Berkeley When the Great Depression made jobs in chemistry scarce Professor Krauskopf decided to study geology which had long fascinated him Through additional graduate work at Stanford University he earned a second Ph D and eventually a position on the Stanford faculty He remained at Stanford until his retirement in 1976 During his tenure Professor Krauskopf also worked at various times with the U S Geological Survey served with the U S Army in occupied Japan and traveled to Norway France and Germany on sabbatical leaves His research interests included field work on granites and metamorphic rocks and laboratory study on applications of chemistry to geologic problems especially the formation of ore deposits In later years Professor Krauskopf spent time working with various government agencies on the problem of radioactive waste disposal Professor Krauskopf passed away on May 8 2003 Arthur Beiser a native of New York City received B S M S and Ph D degrees in physics from New York University where he later served as Associate Professor of Physics He then was a Senior Research Scientist at the Lamont Geological Observatory of Columbia University His research interests were chiefly in cosmic rays and in magnetohydrodynamics as applied to geophysics and astrophysics In addition to theoretical work he participated in a cosmic ray expedition to an Alaskan peak and directed a search for magnetohydrodynamic waves from space in various Pacific locations A Fellow of The Explorers Club Dr Beiser was the first chairman of its Committee on Space Exploration He is the author or coauthor of 36 books mostly college texts on physics and mathematics 14 of which have been translated into a total of 27 languages Two of his books are on sailing The Proper Yacht and The Sailors World Figure 13 21 is a photograph of Dr Beiser at the helm of his 58 ft sloop he and his wife Germaine have sailed over 150 000 miles including two Atlantic crossings and a rounding of Cape Horn Germaine Beiser who has degrees in physics from the Massachusetts Institute of Technology and New York University is the author or coauthor of seven books on various aspects of physics and has contributed to The Physical Universe For a number of years she was the editor of a cruising guide to the Adriatic Sea xx Preface Meet the Authors Konrad B Krauskopf was born and raised
