![]() In the book, the Way Station is a galactic transfer point that has been built into an existing building. In this case, an old cabin belonging to a Civil War veteran. The entire exterior surface of the cabin is protected by an impenetrable, frictionless coating.
The concept of a frictionless surface is relatively modern. In the 4th century BC, the natural philosopher Aristotle postulated that, to keep a body in motion, a constant force must be applied. Given our daily experience, this seems to be true - nothing keeps moving forever. Following the work of Newton and others, however, the idea of a frictionless surface or environment (like airless space) came to be widely discussed in science.
What solid has the lowest coefficient of friction? As far as anyone knows, polytetrafluoroethylene (PTFE), a polymer of fluorinated ethylene, is the slipperiest solid material. PFTE is better known under its brand name - Teflon. It was discovered in 1938 by Roy J. Plunkett at DuPont; it was made available as a commercial product after WWII in 1946.
Compare to telelubricator from The Exalted (1940) by L. Sprague de Camp. Comment/Join this discussion ( 2 ) | RSS/XML | Blog This | Additional
