It’s considered rude to ask a person their age. But like someone sensitive on the subject, the universe has offered up many conflicting ages. History records that the answer to the title question depends strongly on when the question was asked. The discovery that stars age and die was a beginning of our modern understanding of cosmology, and gives us an insight into what the universe will look like in the future.

The University of Kentucky Department of Physics and Astronomy is pleased to welcome the public to our astronomical observatory. Part of our program of public outreach is a presentation on an interesting topic in astronomy followed by a visit to the observatory. The Kentucky SkyTalk is held on the second Thursday of every month.  A 45 minute program on astronomy will begin at 8:00 PM in Room 155 of the Chemistry-Physics Building. After the presentation, you are invited to view the sky through our 20-inch telescope, weather permitting.

Free parking is available on the top floor of parking structure #2, next to the observatory. With the exception of paid parking, without a valid parking permit, leaving your vehicle somewhere other than next to the observatory will result in a parking citation.

All are welcome and there is no charge. Tell your neighbors. Bring your kids.

While the role of social media has been feverishly debated in fomenting, planning, and sustaining revolutions since twitter was first hailed—somewhat exaggeratedly—as a revolutionary technology in Moldova in 2009 and YouTube became a people's archive for election protests in Tehran during the summer of that same year, it seems incontestable that broadcast media (often singular, uni-directional, and hierarchical) are being supplanted by decentralized, multi-directional "public utterances" from social media. The result is a significantly more adaptable, amorphous, global, but also ephemeral public sphere. However, even with the best intentions, social media can amplify misinformation on a global scale, creating an echo chamber of falsehoods that are easily accepted as truths by virtue of their sheer repetition.  And more ominously, social media can be tracked and used to squelch the very voices that use it.  In this talk, Todd Presner will discuss a series of projects that analyze the role of social media in the Middle East, starting with the 2009 Tehran election protests and going up to the 2011 "Arab Spring," including twitter projects such as the "Voices of January 25th" (Egypt), "Voices of February 17th" (Libya), and HyperCities as examples. 

Todd Presner is Professor of Germanic Languages and Comparative Literature at the University of California Los Angeles.  He is the Chair of UCLA’s Digital Humanities Program and also the Sady and Ludwig Kahn Director of the UCLA Center for Jewish Studies. With Anne Burdick, Johanna Drucker, Peter Lunenfeld, and Jeffrey Schnapp, he is the co-author of Digital_Humanities (MIT Press, 2012). His most recent book is HyperCities: Thick Mapping in the Digital Humanities (Harvard University Press, 2014), with collaborators David Shepard and Yoh Kawano. Projects can be seen at this website: http://thebook.hypercities.com.

A reception will follow the program in the Alumni Gallery.
