John F. Ptak
I have operated a bricks-and-mortar bookstore dedicated to the history of science from 1985-2003, located primarily in Georgetown, Washington, D.C. The store's website has been in operation since 1998, and it is now the principle venue for business. From 2003-2008 I owned and operated an antique map and print store near the town square in Asheville, North Carolina.
Interests: art, math, history of science and technology; connections between/among physics, literature; the naive surreal; outsider art and logic; discrete ephemera.
