Amanda Peet, University of Toronto Four decades ago, Stephen Hawking posed a paradox about black holes and quantum theory that still challenges the imaginations of theoretical physicists today. One of the most promising approaches to resolving the "information paradox" (the notion that nothing, not even information itself, survives beyond a black hole's point-of-no-return event horizon) is string theory, a part of modern physics that has wiggled its way into the popular consciousness.

The visionary Oscar-winning writer and director of Gravity introduces Stanley Kubrick's science-fiction masterpiece.

Is our universe the only one? How do we prevent a zombie plague? Will biometrics eliminate privacy altogether? Will climate change put fish in hot water? Should we trust the machines? Join York University professors Matthew Johnson, Jane Heffernan, Demian Ifa, Sapna Sharma and Edward Jones-Imhotep in a conversation with CBC Radio’s The Current host Anna Maria Tremonti on five big questions for the next 50 years.

Westfield Heritage Village is having a Star Party and you won't want to miss it!

Start your own space program and reach to the stars! Kerbal Space Program is an award winning game that teaches players real-world physics and engineering skills as they attempt to explore the Kerbal solar system. Players assist the lovable-but-hapless Kerbals as they build rockets and carry out orbital missions. In the end players learn the difficulties NASA and ESA face when traveling to the stars. This multi day program will start out with a tutorial, and then attempt a mission to the moon or even another planet.

Speaker: Phil Mozel, Mississauga Centre RASC The last two years have seen numerous celebrations to commemorate the bicentennial of the War of 1812. Many battles took place very close to the venue of Mississauga Centre meetings. Of possible interest to amateur astronomers is the state of astronomical knowledge at this time when war raged not only across parts of Canada and the United States but in Napoleonic Europe as well. As an amateur historian, Phil will also reveal, through his alter ego, his special connection to this period.

The Department of Physics invites faculty, students and the public to our 40th annual celebration of physics. The Welsh Lectures in Physics have been held annually since 1975 in honour of H.L. Welsh, a distinguished former faculty member in the Physics Department. They are the major public event in the life of the Department of Physics and are intended to celebrate discoveries in physics and their wider impact. They are intended to be broadly accessible to an audience drawn from across the university, other academic institutions and the interested public.
