The Isaac Newton Medal is a prize awarded annually by the Institute of Physics and is valued at £1000. The award is given to a physicist, regardless of subject area, background or nationality, for outstanding contributions to physics. The award winner is invited to give a lecture at the Institute.
2010 Edward Witten for "his many profound contributions that have transformed areas of particle theory, quantum field theory and general relativity."
2009 Alan Guth for "his invention of the inflationary universe model, his recognition that inflation would solve major problems confronting then-standard cosmology, and his calculation, with others, of the spectrum of density fluctuations that gave rise to structure in the universe".
2008 Anton Zeilinger for "his pioneering conceptual and experimental contributions to the foundations of quantum physics, which have become the cornerstone for the rapidly-evolving field of quantum information".
