The Exact Renormalization Group
4 talksCollection NumberC08006A series of four lectures exploring the Exact Renormalization Group. This non-credit mini course will be offered at Perimeter Institute between April 16 and May 7 2008. -
Symmetry Principles in Physics: Variations on a Theme
10 talksCollection NumberC08007These lectures will cover a number of topics related to the role of symmetry principles in physics. After introducing some basic definitions and distinctions, we will look at the changing role of the relativity principle from Galileo to Einstein (in special and general relativity). In particular we raise doubts as to the wisdom of treating Einstein's 1905 route to special relativity based on the relativity principle as a template for a fundamental reformulation of quantum theory, as some have recently proposed. We then examine the nature and meaning of Noether's 1918 theorems for global and local symmetries, and discuss some recent applications of Noether's "first" theorem in quantum mechanics and electromagnetism. We finish with two case studies: (i) the Galilean (boost) symmetry of quantum mechanics, and (ii) the problem of the arrow of time in statistical mechanics based on time-reversal invariant dynamics. Each lecture will be followed by a period for discussion. -

New Horizons In Fundamental Physics
23 talksCollection NumberC08001This course is an introduction to some of the most exciting ideas in fundamental physics. The topics are chosen to represent areas of research currently conducted at Perimeter Institute. Each topic will be discussed for one or two weeks and will be lectured by a leading young researcher in each field. From deep conceptual issues on the meaning of quantum theory, passing through very sophisticated theories like string theory and loop quantum gravity all the way to cosmology and quantum information theory, this course is a challenging intellectual adventure. -
Special Topics in Physics
27 talksCollection NumberC08003This course will provide an introduction to current research on the problem of time in quantum gravity and cosmology. This is one of the key problems that any successful quantum theory of gravity must solve. Different approaches to quantum gravity assume different answers to fundamental questions such as whether time is emergent or not, whether causality is emergent or not, and what is an observable in a theory of gravity. These problems have aspects which are technical as well as conceptual and philosophical aspects and we will discuss them all as well as their inter-relations. The course will begin with an introduction to the canonical formulation of general relativity and related dynamical systems. We will then study the standard material on the Hamiltonian quantization of general relativity and related time reparametrization invariant systems. This gives us the technical setting in which the problem of time is usually encountered in the contemporary literature on quantum gravity and quantum cosmology. Following this physical introduction we will read the key texts from the history of physics and philosophy concerning the meaning of time, such as Newton, Leibniz, Mach, Einstein etc. This will be followed by readings of papers and books from contemporary sources on this issue by physicists and philosophers. We will focus on two opposite views, the idea that time is emergent in quantum cosmology and the opposing idea that time is fundamental and is perhaps the only aspect of our macroscopic reality that is not emergent. -
