( Click Here to be a Sponsor of the Edwin P. Hubble Lecture Series )


The next general meeting of the
Chicago Astronomical Society
will be held at the
Cernan Earth and Space Center,
1701 Fifth Ave, River Grove, IL
on
Astronomy Day!
Saturday, May 18,

Please note! - This meeting will have a different format than previous meetings.


The CAS May lecture,
"Did you feel that?" - gravitational radiation, LIGO/Virgo, LISA, and the dawn of non-photonic astronomy.
will be given by
Dr. Joshua Burton.
Lecture synopsis:
The ability to detect gravitational waves opens a new window to study the universe that is unique in that it doesn’t rely on any electromagnetic radiation. Gravitational waves are 'ripples' in space-time that are caused by some of the most violent and energetic processes in the Universe. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity. Einstein's mathematics showed that massive accelerating objects (things like neutron stars or black holes orbiting each other) would disrupt space-time in such a way that 'waves' of undulating space-time would propagate in all directions away from the source. These cosmic ripples would travel at the speed of light, carrying with them information about their origins, as well as clues to the nature of gravity itself.


Our speaker Dr. Joshua Burton earned his Ph.D. in 1990 from UC Berkeley, where he worked with Mary K. Gaillard and Bruno Zumino during the exciting early years of supergravity and string theory. He has held research appointments at the Weizmann Institute of Science, Harvard, Brown, and Northwestern, publishing original work on supersymmetry, particle astrophysics, cosmology, and high-energy physics beyond the Standard Model. In 1997, a friend's start-up company lured him away from academia into software, and through acquisition he eventually wound up at IBM. He retired in 2016 to return to his true calling as a physics educator, and now teaches physics and runs the astronomy club at our award-winning local Proviso Mathematics and Science Academy.

We would like to thank the Cernan Center and its director Kris McCall for their support of the CAS and astronomy/science education. We encourage CAS members and all others who support science education to purchase memberships for the Cernan Center. We hope that you can attend. Please feel free to forward and invite friends!

Clear Skies!
