Online Enrichment Begins Next Week

High school students can dive deeper into gravity and the quantum world through two online courses running October 12-28, 2018. Students work at their own pace, submit short assignments for instructor feedback, and can join discussion forums with students around the world.

Images from the Edge of Spacetime:
Resolving Black Hole Horizons

Avery Broderick
Perimeter Institute and University of Waterloo

Wednesday, Oct. 3 @ 7:00 pm EDT

Black holes are among the most powerful and mysterious phenomena in the universe. Almost every galaxy has at its core a supermassive black hole, millions or even billions of times more massive than our sun. Black holes are, in theory, the ultimate manifestation of strong gravity’s impact on the visible universe, but placing these exotic phenomena on concrete empirical footing has been impossible — until now. The Event Horizon Telescope (EHT), a global array of interconnected telescopes, has such incredible power and precision that it may finally unveil nature’s monsters in the dark. 

In the first lecture of Perimeter's 2018-19 Public Lecture Series, Avery Broderick will talk about the EHT and international efforts to interpret horizon-resolving images of numerous supermassive black holes. Find out more about the upcoming lecture live stream.

Slice of PI

It can be said that science and poetry share the common purpose of revealing profound truths about the universe and our place in it, though some would have dismissed that idea as hogwash.

“The aim of science is to make difficult things understandable in a simpler way; the aim of poetry is to state simple things in an incomprehensible way,” physicist Paul Dirac once grouched to a colleague.  “The two are incompatible.”

Still, physicists have often turned to poetry to express ideas for which equations alone do not suffice. Here’s a look at some of the loveliest stanzas from physicists past and present, plus a couple of silly ones.
