Michael A. Seeds has been Professor of Physics and Astronomy at Franklin and Marshall College in Lancaster, Pennsylvania, since 1970. In 1989, he received F&M College's Lindback Award for Distinguished Teaching. Seeds' love for the history of astronomy led him to create upper-level courses on Archaeoastronomy and Changing Concepts of the Universe. His research interests focus on variable stars and the automation of astronomical telescopes. Mike is coauthor with Dana Backman and Michele Montgomery of HORIZONS HYBRID: EXPLORING THE UNIVERSE, Thirteenth Edition, and UNIVERSE HYBRID: SOLAR SYSTEM, STARS AND GALAXIES, Eighth Edition, both published by Cengage. He was Senior Consultant in the creation of the twenty-six-episode telecourse accompanying the book HORIZONS: EXPLORING THE UNIVERSE, Twelfth Edition.

Based on their best-selling astronomy textbook, authors Mike Seeds, Dana Backman, and Michele Montgomery present HORIZONS HYBRID: EXPLORING THE UNIVERSE, Thirteenth Edition, to help you understand your place in the universe--not just your location in space but your role in the unfolding history of the physical universe. To achieve this goal, they focus on two central questions: "What Are We?" which highlights your place as a planet dweller in an evolving universe, guiding you to better understand where we came from and how we formed; and "How Do We Know?" which provides insights into how science works and how the process of science can teach us more about what we are.
