This will be a twinnd conference held simultaneously at Perimeter Institute in Waterloo, Canada and Max Planck Institute in Bonn, Germany. The two venues will be connected by live video streams, during both the talks themselves as well as informal discussion sessions. The concept of the twinned conference is motivated by the desire to reduce environmental impact of conference travels. Our hope is that this initiative will help reduce transatlantic flights, while still promoting long distance interactions.
