L. L. Williams Libri

This volume contains the scheduled technical proceedings of the Estes Park Advanced Propulsion Workshop, 19-22 September 2016, Estes Park, Colorado. The workshop was modeled on the famous Shelter Island conference, and it drew together theorists and experimentalists working in the field of breakthrough propulsion. The sessions were structured to allow two hours per concept, with detailed audience interchange. The Space Studies Institute has made available videos of the workshop. This volume collects prep material sent to participants before the meeting, proceedings papers for each session, and a summary of the session discussion. Two propellantless propulsion devices received special consideration. One was based on a clever electromechanical manipulation purported to couple into the gravitational field of the universe, called by its inventor "the Mach effect." Another purported to produce thrust with a simple, asymmetrically-shaped microwave cavity, sometimes called an "EM-drive," for electromagnetic drive.

This work presents a collection of essays and character sketches that explore various facets of the world, offering insightful observations and reflections. Originally published in 1897, it provides a unique glimpse into the thoughts and societal norms of the time, making it a valuable resource for readers interested in historical perspectives. The reprint maintains the quality of the original edition, ensuring that the essence of the author's insights is preserved for contemporary audiences.
