New Lights on Dark Matter - 2009
In the last few years, a new observational window has opened on the dark sector of matter. The recent flood of experimental results on direct and indirect dark matter detection has potentially revolutionized our view of the nature of dark matter. As the non gravitational nature of dark matter may well be revealing itself for the first time, initial results have lead to a reexamination of WIMP physics with the aim of enhancing the annihilation cross section through various means, and encouraged theorists to think of more exotic possibilities. The purpose of this workshop is to bring together leading theorists in this area, as well as representatives of the recent experiments, to encourage the sharing and debating of recent results and approaches to probing and describing the dark matter sector. -

New Prospects for Solving the Cosmological Constant Problem - 2009
The `Cosmological Constant Problem’ is one of most outstanding problems in theoretical physics. It is a significant theme of many current areas of research, both at theoretical level, and at the experimental level, via the increasing observational evidence for dark energy. However, the way researchers address this problem varies tremendously between different scientific communities. The principal aim of this workshop is to bring together leading researchers in neighboring fields, to reach a common understanding of the nature of the problem, and to share the tools used in addressing it. In parallel, this workshop aims at understanding how the different directions in solving the Cosmological Constant Problem are related as well as searching for genuinely new approaches to tackle the question. -

The Economic Crisis and It's Implications for The Science of Economics - 2009
The Perimeter Institute conference on economics is being organized in an effort to better evaluate the state of economics as a predictive and descriptive science in light of the current market crisis. We believe that this requires careful, dispassionate discussion, in an atmosphere governed by the modesty and open mindedness that characterizes the scientific community. To do this we aim to bring leading economists and theorists of finance together with physicists, mathematicians, biologists and computer scientists to evaluate current theories of markets, and identify key issues that can motivate new directions for research. The conference will begin on May 1, 2009, with a day of invited talks by leading experts to a public audience of around 200 on the status of economic and financial theory in light of the crisis. We will then continue for three days of focused discussion and workshops with an invited group of around 30, aimed at defining research agendas that address that question and beginning work on them. -
Sunyaev-Zeldovich Universe and the Future of Cluster Cosmology - 2009
Galaxy clusters have played a crucial role in the development of modern cosmology over the past century. Thanks to the next generation of high resolution microwave telescopes, a new generation of cluster surveys (detected through the Sunyaev-Zel'dovich (SZ) effect) are under way and promise to provide us with a catalog of hundreds to thousands of new high redshift clusters over the next few years. This conference aims to bring together experts in SZ observations and cluster cosmology to understand the status/implications of current clusters surveys, and find a consensus on the future promise/prospects of cosmology with galaxy clusters. -

Introduction to the Bosonic String
This course provides a thorough introduction to the bosonic string based on the Polyakov path integral and conformal field theory. We introduce central ideas of string theory, the tools of conformal field theory, the Polyakov path integral, and the covariant quantization of the string. We discuss string interactions and cover the tree-level and one loop amplitudes. More advanced topics such as T-duality and D-branes will be taught as part of the course. -
ISSYP Virtual
Here is your opportunity to experience, online, select content from Perimeter Institute's highly successful two-week International Summer School for Young Physicists (ISSYP). While we could reach up to 100 "young physicists" per year with our onsite ISSYP camps, our Virtual ISSYP opens up this fantastic learning experience for all to enjoy. The Virtual ISSYP is intended for students, teachers and anyone interested in learning more about the wonders of modern physics and the excitement of research and discovery at the frontiers of knowledge.
