Perimeter Institute: The Quantum Revolution: Shohini Ghose public lecture

You’ve likely heard of quantum computing. This emerging form of technology harnesses counter-intuitive properties of the subatomic realm to perform tasks that would overwhelm even today’s most powerful “classical” computers. But do you know what that will mean for the ways you work, communicate, play, and live? Does anyone truly know? Well, no, because some very big challenges remain before quantum computers are commonplace. But for an expert perspective on how to prepare for the quantum future, you’d be hard-pressed to find a better source than Shohini Ghose.

Hamilton Amateur Astronomers: SETI: An Exploration of Space and Astronomy

Guest speaker Stephen Holmes writes: “I suspect we all wonder about alien civilizations. SETI, the search for extraterrestrial intelligence, and the Drake Equation set out some tools to help us get our heads around these huge numbers and consider realistically how plentiful or rare these civilizations are. Astronomy gives us the tools to determine realistically the star systems that might host these civilizations. Join me to consider some of these considerations.”

RASC, Mississauga Centre: Apollo 13 - The Flight That Failed (CANCELLED)

Due to the COVID-19 crisis and the suspension of in-person classes at UTM, we have cancelled this meeting. Fifty years ago, the third mission was launched to land two people on the Moon. On the third day of the flight, a problem occurred which cancelled the plans for the lunar landing and instead, started a race to get the astronauts home alive. In this talk, Randy Attwood will detail all the things which had to go right to save the Apollo 13 crew.
