Dr. Geoffrey F. (Geoff) Davies is a scientist, author and commentator. Born to a farming family and growing up in Australia, Geoff's life has taken him to the USA and back and through several important stages - student, scientist, commentator, learning to be a real person (i.e. growing up some more), father, grandfather and Author Outside His Designated Field. These days he is less concerned with exploring the universe and more concerned with helping humanity to live sensibly with each other on the only planet we have. On economics: Geoff is the author of Economia (2004), the eBook The Nature of the Beast (self-published, 2012), and the eBook Sack the Economists (2013). The commentator: Geoff has contributed opinion pieces over many years to local newspapers and magazines. Since 2009 he has preserved them on the blog http: //betternature.wordpress.com . He has long experience, in science and elsewhere, in assessing fractious debates on difficult topics. He has lectured on New Science and Old Wisdom and Playing With Superfire (the misapplication of technology to biological systems). The Scientist: Geoff is a retired Senior Fellow (now a Visiting Fellow) in geophysics at the Australian National University. He has authored over one hundred scientific papers and two scientific books and has a Hirsch index of 38 (38 papers each with at least 38 citations, indicating significant international standing and influence). In 2005 he was awarded the inaugural Augustus Love medal for geodynamics by the European Geosciences Union.  He was selected in 1992 as a Fellow of the American Geophysical Union. His most recent scientific book, Mantle Convection for Geologists, won the 2011 Mary B. Ansari Best Reference Work Award of the GeoScience Information Society.
