Electrical Resistance: an Atomistic View
Papers | 26 Oct 2006 | Contributor(s):: Supriyo Datta
This tutorial article presents a “bottom-up” view of electrical resistance starting from something really small, like a molecule, and then discussing the issues that arise as we move to bigger conductors. Remark ably enough, no serious quantum mechanics is needed to understand electrical...

Scientific Ethics and the Signs of Voodoo Science
Online Presentations | 18 Oct 2006 | Contributor(s):: Andrew S. Hirsch
Until recently, the issue of research ethics had not been a subject of explicit discussion within the Physics community. Over the past ten years, however, documented cases of scientific fraud have brought this issue to center stage. We will explore, through case studies, some examples ranging...
