"Imaging Fundamental Processes (Thought, experiment and the accessible universe)"
The contemporary theory of fundamental forces can be pictured as just a handful
of particle species, acting among themselves according to a few simple rules.
This theory can in principle account for the richness of the visible universe.
It results from a centuries-long process of speculation and investigation,
culminating in the language of quantum field theory. Yet every successful
theoretical framework defines its own limitations, and suggests new questions
and criteria. Looking back and ahead, I'll give a perspective on our current
theories and viewpoints, and on how future developments may be influenced by
evolving ideas in theoretical physics, by high energy experiments at accelerators,
and by exquisite observations of the faintest cosmic signals.
