Gravity and LIGO

by Barry Mingst

Sierra College

Barry will present information on Gravity Waves and their relationship to Super Nova, Neutron Stars and Black Holes. Starting in 2015, with upgrades to two Laser Interferometer Gravitational-Wave Observatories (LIGO), 5 separate observations of Gravity Waves have been detected 'simultaneously' at both of the LIGO Observatories in the United States.  What are gravity waves and what is their relationship to Neutron Stars and Black Holes.  Barry will help us understand this exciting topic in 21st Century Gravity Science.

Aperture Fever
by Lonnie Robinson and Tom Osypowski

No one since the time of Galileo, has been more responsible for the spread of Aperture Fever than John Dobson.  He revolutionized Amateur Telescope Making by pioneering the building of large aperture telescopes – light buckets.  

Aperture is the diameter of the first optical component (mirror or lens) of a telescope which determines how faint and the details which can be seen.  Often after a first scope Aperture Fever begins and then the question is what will the cure cost?  The talk will explore the tradeoffs from building your own to purchasing a truly large instrument with all the bells and whistles.
