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.

Showtimes: 7:00pm, 8:00pm, and 9:00pm Gravity binds the universe together. From the hundreds of billions of stars dancing around our Milky Way galaxy, to the moons orbiting Jupiter, to satellites that circle overhead, gravity is present everywhere and shapes our existence. Join us for an evening exploring this wondrous force of nature. Your show will be approximately 50 minutes long. All of our shows are presented live and in person by University of Toronto astronomers. Plenty of time is allocated for questions from the audience.

Everyone is invited to join the DRAA for a fun evening of stargazing at Millennium Square in Pickering. You will enjoy spectacular views of the Moon, Venus, Jupiter, Saturn and deep space star clusters through big telescopes. The DRAA will have an information booth filled with astronomy literature and hand outs. Do you have a telescope but are not sure how to use it? Bring it along and DRAA members will be happy to help you!

William Shakespeare lived at a remarkable time - a period we now recognize as the first phase of the Scientific Revolution. New ideas were explored, and medieval thinking was giving way to modern thought. In this talk, award-winning journalist and author of The Science of Shakespeare Dan Falk will explore Shakespeare's interest in the scientific discoveries of his time.

The weekend of April 10–12th, developers, makers, engineers and entrepreneurs will take on NASA-designed challenges, creating solutions that range from silly to serious, fantastical to feasible. Build a team, pick a challenge, and leverage your access to an extraordinary roster of mentors featuring past and present astronauts, aerospace engineers, and designers.

This is the story of Apollo astronaut Eugene Cernan, one of the few men who paved the perilous path to lunar exploration. One of only three men who travelled to the moon twice, his second trip in 1972 was NASA’s final lunar mission, making him the last man to ever set foot on the moon. Now, more than forty years later, he is ready to share his epic, deeply personal, story. It is a tale of burning ambition set against the spectacular and hazardous environment of space, and the heavy price of fame.

Witness Earth like never before. Through telescopic lenses positioned in deep space that are trained on the peaks of the Himalayas, the African savannas, the hyper-paced streets of Tokyo and the vastness of the cosmos themselves, this visually astonishing portrait of our planet is designed to humble the viewer. In an effort to grasp not only the fragility and beauty of this world, but the near-incalculable breadth of our impact on it, Planetary intellectually challenges us to reconsider our relationship with our home.

The Toronto Chapter of the Canadian Space Society will be holding a Yuri’s Night networking event on Friday, April 10th starting at 6:30 pm. It will be held at the Fox & Fiddle - Yorkville at 280 Bloor Street West, Toronto. It will be a fairly informal gathering with door prizes and there will be a chance for space groups to give a short blurb about their group and any upcoming events/projects. Come out, socialize over drinks and pub grub, renew old acquaintances, and make some new friends.

Speaker: Dr. Michael Reid, Dunlap Institute for Astronomy & Astrophysics The Big Bang Theory is one of the crowning achievements of modern science. The basic premise—that the universe began expanding about 14 billion years ago from a very hot, dense state—has been independently verified many times over. And yet there is widespread confusion and uncertainty about what the theory actually says—and what it doesn't.
