Dr. John A. Cramer is an emeritus Professor of Physics at Oglethorpe University in Atlanta, Georgia having earned his PhD. Degree from Texas A&M University. He has some forty years of experience teaching undergraduate physics and physical sciences and has authored numerous popular science articles. An avid outdoorsman and shell collector, his science interests extend well beyond physics.
Dr. Cramer’s books include: A Brief History of Physical Science, How Alien Would Aliens Be? Why You Can't Shoot Straight: the basic Science of Shooting and Science Activities for K-5. All these are available in ebook formats. A Brief History of Physical Science, and How Alien Would Aliens Be?, are also available in print at most online retailers.
How alien would aliens be? Like us, aliens would be constrained by the physical world. That implies that they will not be all that different from us, perhaps half to twice as big as we are. They will depend on vision and hearing as we do and they will live on a planet much like ours. Do they even exist? The odds are not good. We may be the only intelligent life in the universe.
This book traces the development of the modern scientific understanding of the physical world. The historical approach allows us to see not only how the content of the physical sciences was formed but also how cultural, philosophical and religious influences and attitudes have played a major role in that development.
K-5 teachers often feel uncomfortable teaching science, especially physical sciences. This book is for them. I emphasize teaching by activities so the book is a compendium of activities and demonstrations in all the science areas covered by the Georgia Performance Standards. Students come to love the course and materials and you will too. The book covers every science GPS and more.
Beginning with the most basic science, that gravity means you can never shoot straight, this book clearly and carefully explains the physical science behind all aspects of shooting. First it covers the basics of projectile motion, air resistance effects and the impact of rotational. It then moves to advanced and applied science topics like recoil control and optics of sighting and scopes.
