Scientific Ethics and the Signs of Voodoo Science
24 Sep 2007 | Online Presentations | 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. Looking at case studies, this talk explores examples ranging...
