A million years after the birth of our sun, the violent explosion of a nearby supernova nearly ended life on Earth before it began. Over the next four and a half billion years, forces of nature shaped our planet and the life it harbored. Barely surviving the traumatic birth of the Moon, buffeted by supernovae, and bombarded by asteroids, the resilient Earth endured. And despite planet-freezing ice ages, devastating mass extinctions, and ever changing climate, life not only survived, it thrived. Today, we are told all life on Earth is threatened by a new peril--human-caused global warming. The Resilient Earth presents the science behind global warming for a general audience, separating fact from fiction and truth from exaggeration.
Doug L. Hoffman has worked professionally as a mathematician, a computer programmer, an engineer, a computer salesman, a scientist, and a college professor. Dr. Hoffman earned his undergraduate degree, a BS in Applied Mathematics, from the Florida Institute of Technology. There he cut his teeth on computer models of heat flow and urban traffic simulations. After graduating, he performed hydro-acoustic work for the U.S. Navy in the Virgin Islands, where he first met Allen Simmons. Later projects included engineering work on the Carrier Automatic Landing System and cockpit field of view simulations, and environmental models for the Saudi Arabian government.
He returned to academia in 1990, earning a Masters degree and a PhD in Computer Science at the University of North Carolina at Chapel Hill. While there he did research in Molecular Dynamics Simulations and, as a member of the BioSCAN team, he helped develop and implement high-speed comparison methods for RNA, DNA, and protein sequences, work funded by the Human Genome Project. After joining the research faculty at UNC, he continued to pursue his thesis work, automated comparison of three dimensional protein molecules.
Since 2000, he has been working in industry, serving as an expert architect for a major information processing company, publishing several papers on modeling the performance of large scale grid computers. With a life long passion for education, he has also continued to teach Computer Science at Hendrix College and the University of Central Arkansas.
