Since 2002 Perimeter Institute has been recording seminars, conference talks, and public outreach events 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 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.
Consider a discrete quantum system with a d-dimensional state space. For certain values of d, there is an elegant information-theoretic uncertainty principle expressing the limitation on one's ability to simultaneously predict the outcome of each of d+1 mutually unbiased--or mutually conjugate--orthogonal measurements. (The allowed values of d include all powers of primes, and at present it is not known whether any value of d is

Shear viscosity is a transport coefficient in the hydrodynamic description of liquids, gases and plasmas. The ratio of the shear viscosity and the volume density of the entropy has the dimension of the ratio of two fundamental constants - the Planck constant and the Boltzmann constant - and characterizes how close a given fluid is to a perfect fluid. Transport coefficients are notoriously difficult to compute from first principles.

Thermodynamics places surprisingly few fundamental constraints on
information processing. In fact, most people would argue that it imposes
only one, known as Landauer's Principle: a process erasing one bit of
information must release an amount kT ln 2 of heat. It is this simple
observation that finally led to the exorcism of Maxwell's Demon from
statistical mechanics, more than a century after he first appeared.
Ignoring the lesson implicit in this early advance, however, quantum
In an anisotropic limit of the weakly-coupled, 2+1-dimensional non-Abelian
gauge theories are equivalent to a collection of integrable
1+1-dimensional quantum field theories. This fact makes it possible to
understand confinement near this limit. Using exact form factors, it is
possible to study the theory away from the extreme anisotropic limit. The
string tension between fundamental color sources is found. Adjoint sources
are not confined. Some ideas concerning the isotropic case and the
generalization to 3+1 dimensions will be discussed.
