Title: Chandrasekhar’s Limit Speaker: Keith Jarvie, Ph.D. Keith’s talk examines (at the level of an amateur enthusiast with minimal math skills) the interplay between the birth of quantum mechanics, and its application to understanding the life cycles of the stars’. The historical record is traced through the lives of the scientists who contributed to the field, each of whom provides clear evidence of their genius, and in numerous instances, their eccentricities.

- Ceres’ “Pyramid” Gets a Closer Look, But Bright Spots Remain a Mystery August 26, 2015The Dawn spacecraft is now orbiting just 1,470 kilometers (915 miles) above Ceres’ surface, and the science team released these latest images. Above is a closest view yet of the so-called ‘pyramid’ on Ceres, although the closer Dawn gets, the less this feature looks like a pyramid. It’s actually more like a conical mountain with […]Nancy Atkinson
