Since 2002 Perimeter Institute has been recording seminars, conference talks, public outreach events such as talks from top scientists using video cameras installed in our lecture theatres. Perimeter now has 7 formal presentation spaces for its many scientific conferences, seminars, workshops and educational outreach activities, all with advanced audio-visual technical capabilities.
Recordings of events in these areas are all available and On-Demand from this Video Library and on Perimeter Institute Recorded Seminar Archive (PIRSA). PIRSA is a permanent, free, searchable, and citable archive of recorded seminars from relevant bodies in physics. This resource has been partially modelled after Cornell University's arXiv.org.
Accessibly by anyone with internet, Perimeter aims to share the power and wonder of science with this free library.
Space and time are two of the universe's most fundamental elements. Relativity combines these two into the unified notion of space-time, but twistor theory goes beyond this replacing both by something entirely different, where the basic elements are the paths taken by particles of light or other particles without mass.
Twistor theory has already found powerful applications in the field of high-energy physics.
One of the great promises of the Advanced LIGO era is the prospect of
integrating gravitational wave astronomy into the greater astronomical
community. This will allow for measurements that cross spectral bands
and provide new paths for insight into some of the most violent
processes in the universe. In this talk I'll discuss past and present
efforts with Initial and Enhanced LIGO to search for transients with
both electromagnetic and gravitational wave signatures, with special
focus on electromagnetic followups of inspiral events and an eye
In this talk, I will first give an overview of holographic entanglement entropy. Next I will introduce recent our results on its applications to the quantum quenches and a holography for flat spacetime.
