THE 2008 DIRAC MEDAL AND PRIZE
The 2008 Dirac Medal and Prize will be awarded to

Juan Martin Maldacena, Joseph Polchinski and Cumrun Vafa for their fundamental contributions to
superstring theory. Their studies range from early work on orbifold compactifications, physics and
mathematics of mirror symmetry, D-branes and black hole physics, as well as gauge theory-gravity
correspondence. Their contributions in uncovering the strong-weak dualities between seemingly different
string theories have enabled us to learn about regimes of quantum field theory which are not accessible to
perturbative analysis. These profound achievements have helped us to address outstanding questions like
confinement of quarks and QCD mass spectrum from a new perspective and have found applications in
practical calculations in the fluid dynamics of quark gluon plasma.

The dualities have also led string theorists to conjecture that the five different superstring theories in ten
space-time dimensions are manifestations of one underlying theory, yet undiscovered, which has been
named the M-theory.
