Exploring the Earth and Cosmos: A Study of Western Civilization

Dr. Hans Mark

John J. McKetta Centennial Energy Chair in Engineering, University of Texas at Austin.

Western history has been one of restless expansion, a pushing out of boundaries both intellectual and geographical. Western exploration has encompassed both heaven and earth, improvements in celestial observation facilitating global navigation and discovery. From the Portuguese voyages into the South Atlantic during the fifteenth century, to trips to the Moon in the twentieth, Western science and Western exploration have gone hand-in-hand.

Dr. Hans Mark is John J. McKetta Centennial Energy Chair in Engineering at the University of Texas at Austin, former Deputy Administrator of the National Aeronautics and Space Administration, former Secretary of the Air Force, and former Chancellor of The University of Texas System.
