Perimeter Public Lectures
The concept of supersymmetry, though never observed in nature, has driven a great deal of research in theoretical physics over the past several decades. Much has been learned through this research, but many unresolved questions remain. This presentation will describe how these questions can lead one down a surprising path: toward the dodecaphony of Austrian composer Arnold Schoenberg.
Mathematics has proven to be "unreasonably effective" in understanding nature. The fundamental laws of physics can be captured in beautiful formulae. In this lecture I want to argue for the reverse effect: Nature is an important source of inspiration for mathematics, even of the purest kind.
We can set foot on faraway planets, in a sense, by exploring the world beneath our
feet. Underground caves provide unique insights into what we might find beneath
alien landscapes. We are studying caves on Earth to understand how they
form, the spectacular minerals they produce, and the unusual creatures – from
microbes to vertebrates – that thrive in them.
By understanding the caves of our own planet, we can use them as models for the
subsurfaces of other planets. This work provides insights into the lava tubes
Derek Muller from YouTube's Veritasium will present a webcast on Wednesday November 27, 2013 at 7pm EST from the Mike Lazaridis Theatre of Ideas at Perimeter Institute.Derek will discuss the question: Do videos really improve student learning? Derek’s PhD in physics education research suggests the answer may be no! In this one hour talk, he will share insights from his research as well as the incredible physics phenomena he has captured for his YouTube channel.Derek Muller created the popular YouTube channel Veritasium in January 2011.
Nearly a century after their discovery, black holes remain one of the most striking, and problematic predictions of general relativity. Even more unsettling is the fact that they actually appear to exist! With only a handful of exceptions, every galaxy contains a supermassive behemoth, millions to billions as massive as the sun, at their center. These supermassive black holes are hardly incidental, they gravitationally power enormous outflows that rule the fates of their hosts.
The world around holds amazing properties. What is even more amazing
is that we are able to understand them, to control them, and turn them
in to technologies. From fire to electricity and magnetism, these
properties have been tamed and have transformed society. But what is
What are the properties of nature that will be tamed in the 21st century and impact all of us? Dr. Raymond Laflamme
