Dream Machines

Abstract

Particle accelerators and their detectors are the world’s most powerful microscopes. They enable us to inspect the constituents of matter at attometer scales, study matter under unusual conditions, and concentrate extraordinary amounts of energy into tiny volumes to create new forms of matter and initiate new phenomena. The progress of particle physics and of accelerator science and technology go hand in hand. I look to the past, present, and future, raising questions that we would like to answer about nature along the way.
