David Tong - Are We Living in the Matrix

David Tong - Are We Living in the Matrix?
:: Abstract ::
The universe is organized according to scale. Little things affect big things. But very little things do not affect very big things. David explains what this means and why it underlies vast swathes of science.

David Tong is a theoretical physicist and a fellow at Trinity College, University of Cambridge including the joint recipient of the 2008 Adams Prize. His current research interest lies within quantum field theory (QFT), a vast topic that touches upon many different parts of physics and mathematics.

Over the years, David has studied aspects of QFT related to string theory, supersymmetry, solitons, geometry, cosmology and condensed matter.
His most-cited paper, "DBI in the sky", provides a possible observational test of one mechanism for inflation in the very early universe.

He is also well known amongst the students for his very enthusiastic lecturing and comprehensive lecture notes for courses he has taught at the University of Cambridge (most notably the ones on quantum field theory). Many more can be found online on YouTube.
