Spacetime and the quantum: united by history
Δημοσιεύτηκε στις 7 Ιαν 2014
Professor Fay Dowker presents her Inaugural Lecture.
Two
major scientific developments - relativity and quantum theory - have
advanced our understanding of the physical world. However, despite their
success in predicting experimental results, they remain revolutions in
waiting.
I will argue that the full potential of these
discoveries will only be realised when they are brought together into a
unified whole. The revolution that general relativity represents - the
replacement of three-dimensional space with four-dimensional space-time
as both stage and actor in the universe's grand play - has so far been
only partially incorporated into the scientific practice of fundamental
physics.
Taking space-time seriously, as general relativity
demands, means adopting the Dirac-Feynman 'sum-over-histories' approach
to quantum theory and gives us our best chance of discovering a theory
of quantum gravity, a framework for all of physics.
