A Map of the Nanoworld: Sizing up the Science, Politics, and Business of the Infinitesimal
Mapping out the eight main nodes of nanotechnology discourse that have
emerged in the past decade, we explore how various scientific, social, and
ethical islands of discussion have developed, been recognized, and are being
continually renegotiated. We do so by (1) identifying the ways in which
scientists, policy makers, entrepreneurs, educators, and environmental groups
have drawn boundaries on issues relating to nanotechnology; (2) describing
concisely the perspectives from which these boundaries are drawn; and (3)
exploring how boundaries on nanotechnology are marked and negotiated by various
nodes of nanotechnology discourse.Comment: 25 page
Rotation and Spin in Physics
We delineate the role of rotation and spin in physics, discussing in order
Newtonian classical physics, special relativity, quantum mechanics, quantum
electrodynamics and general relativity. In the latter case, we discuss the
generalization of the Kepler formula to post-Newtonian order )
including spin effects and two-body effects. Experiments which verify the
theoretical results for general relativistic spin-orbit effects are discussed
as well as efforts being made to verify the spin-spin effects
