Break the Science Barrier - Richard Dawkins - Part 1 of 3
Break the Science Barrier follows the Oxford Biologist Richard Dawkins as he meets with people who have experienced the wonders of science first-hand. We meet the astronomer who first discovered pulsars, the geneticist who invented DNA fingerprinting, a scientist who discovered a protein that causes cancer, and others. Dawkins interviews famous admirers of science such as Douglas Adams and David Attenborough, and asks them why science means so much to them. We also see how dangerous ignorance of

Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from

External Symmetry of Crystals, 32 Crystal Classes
This site is a lecture by Dr. Stephen Nelson from Tulane University that explores the 32 possible combinations of symmetry operations that define the external symmetry of crystals. The lecture defines the six crystal systems (triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and isometric) and explains the derivation of the Hermann-Mauguin symbols (also called the international symbols) used to describe the crystal classes from the symmetry content. Tables and illustrations accompany t
