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. Central to the narrative are the points of collision between Dr. Subrahmanyan Chandrasekhar, and Sir Arthur Eddington, a ‘founding father’ and dominant force in early cosmology. The passage of … Continue reading

- What Are These Strange Scarlet Streaks Spotted on Tethys? July 29, 2015Resembling what the skin on my arms looks like after giving my cat a bath, the surface of Saturn’s moon Tethys is seen above in an extended-color composite from NASA’s Cassini spacecraft showing strange long red streaks.
