Mike Seeds was a professor of physics and astronomy at Franklin and Marshall College (F&M) in Lancaster, Pennsylvania, from 1970 until his retirement in 2001. In 1989 he received F&M College s Lindback Award for Distinguished Teaching. Mike s love for the history of astronomy led him to create upper-level courses on archeoastronomy and on the Copernican Revolution ( Changing Concepts of the Universe ). His research interests focused on variable stars and automation of astronomical telescopes. Mike is coauthor with Dana Backman of FOUNDATIONS OF ASTRONOMY, 14th Edition (2019); STARS AND GALXIES, 10th Edition (2019); THE SOLAR SYSTEM, 10th Edition (2019); and ASTRO, 3rd Edition (2018), all published by Cengage. He was senior consultant for creation of the 20-episode telecourse accompanying his book HORIZONS: EXPLORING THE UNIVERSE. Dana Backman taught with Mike Seeds in the physics and astronomy department at Franklin and Marshall College in Lancaster, Pennsylvania, from 1991 until 2003. He invented and taught a course titled Life in the Universe in F&M s interdisciplinary foundations program. Dana has also taught introductory solar system astronomy at Santa Clara University, plus introductory courses on astronomy, astrobiology, cosmology and the science of climate change in Stanford University s continuing studies program. His research interests focused on infrared observations of planetary system formation and evolution of the solar system s Kuiper belt. Dana is employed by the SETI Institute in Mountain View, California, as lead for the Astronomy Activation Ambassadors teacher professional development program at NASA s Ames Research Center. Dana is coauthor with Mike Seeds of FOUNDATIONS OF ASTRONOMY, 14th Edition (2019); STARS AND GALAXIES, 10th Edition (2019); THE SOLAR SYSTEM, 10th Edition (2019); and ASTRO, 3rd Edition (2018), all published by Cengage.
