  Spring 2017 Public Programs

April 14: No Friday Night Program

April 21: Climate Change – Will It Ruin Your Day – Nicholas M. Guydosh, Ph.D., NASA Earth Ambassador
Scientists tell us that not only are we in for global climate change, but it may be the result of human activity.  We are told that we may be dangerously close to the tipping point, the point of no return where adaptation rather than prevention may be the only option.  Professor Guydosh will examine the scientific evidence of global climate change and also human involvement.  There will be a focus on the scientific methods used to determine global temperatures and carbon dioxide levels in the atmosphere both now and in the distant past.  


April 28: The Physics of Music – Jeff Barker Ph.D., Binghamton University
Why do musical instruments sound the way they do? Why, when playing the same note, does a violin sound different than a trumpet or an oboe?  Professor Barker will discuss the physics behind different types of instruments.  He will discuss wave resonance, use a spectrum analyzer to illustrate harmonics, and will demonstrate how harmonics give a number of instruments their recognizable sound. 

May 5: What goes around – comes around! Brian Cavallaro, “Boomerang Brian”– Special Time: 7PM

Meet local boomerang expert Brain Cavallaro as he demonstrates throwing various boomerangs. Learn about the history, art, and aerodynamics of these returnable ancient hunting weapons. The program will begin with a short presentation and then move to Kopernik’s north lawn for a throwing session. Participants will have the opportunity to try for themselves and to if interested, to buy a boomerang. If you have your own, bring it to be appraised and learn how to properly throw it. 

May 6 (Saturday, 7 p.m.): Moonlight Cafe
Looking for something different to do on a Saturday night?  Gaze at the stars during this adults-only evening at Kopernik. The center is transformed into a Moonlight Café, where you can enjoy fresh-brewed coffee, tea, and delicious desserts along with a fascinating introduction to the stars and outer space. 

Register by May 1 through SUNY Broome Continuing Education at (607) 778-5012.


May 12: TigerTronics UE/Vestal Competition Robot – Deborah Daugherty

Union-Endicott High School

Get an up-close look at the latest robot designed by the Union-Endicott/Vestal Robotics team. Their robot performs autonomous and radio controlled actions to accomplish a number of tasks in a multi-team competition. Students on the team will demonstrate the robot, show video from their recent competition in Pittsburgh and answer questions about its design and operation.  If clear, see Jupiter, Saturn, Mars and the moon.


May 19: Beer Brewing Basics – Seth Weisel, Brewmaster, Galaxy Brewing

Have you ever wondered how beer was made or thought about brewing your own? Learn about the science of brewing and malting.  Find out about barley germination, malting processes, fermentation, and various aspects of beer haze, foam, and color.  Learn about flavor chemistry and spoilage microorganisms.  In addition, enjoy a brief history of brewing from past to present.



May 26: Preview to Cassini’s Grand Finale – Keith Werkman, Ph.D., Kopernik Astronomical Society

The Cassini spacecraft has been in orbit around Saturn for over a decade. Get a review of its findings. See amazing close-up images of Saturn’s rings, moons and atmosphere. Learn about its upcoming deliberate fiery plunge into Saturn’s atmosphere! 

Kopernik is open every Friday night, regardless of sky conditions, March through mid-December.
