Welcome to *Galileo Unbound: The History and Physics of Dynamics*. This is the Blog site where you can find the historical background and the physical concepts behind many of the current trends in the physics of complex systems. It is written at the level of college undergraduates in fields of study like science or engineering. Advanced high school students should be able to find little gems here, too.

The topics here will fall under two headings that mirror my two recent books: Introduction to Modern Dyanamics (Oxford University Press, 2015) and Galileo Unbound (Oxford University Press, 2018). The first is a college junior-level physics textbook describing the mathematical details of modern dynamics. The second is a general interest book on the historical development of the same ideas. The physical concepts in both books will be expanded upon in this Blog at a general level of understanding. I hope you enjoy the broad range of topics that will appear here.
