This is Greetings! My name is Professor LeRoy Larry and welcome to Natural Physics! I will explain in down-to-earth scenarios how the principles of physics could have come about from observing Nature. Each episode begins with a scenario, followed by an example to illustrate the application of these principles in futuristic research at the frontiers of science, such as my astrophysics research, and then concludes with an exploration of how these same principles could have very well been used by ancient cultures and civilizations. Mathematics is naturally encountered and incorporated as the exciting and fun tool of science that it is. Science is the window into our amazing world of Nature and mathematics is the tool to open that window! Natural Physics encompasses current, futuristic, and ancient physics, and ties them together by the principles of physics that are common threads running throughout each!
