Donald Glaser invented the bubble chamber to record charged-particle trajectories in a dense medium. A pressure change brings a liquid into a superheated state; deposited energy along an ionizing track allows bubbles to form. Photographing those bubbles turns a brief microscopic passage into geometry that can be measured repeatedly. His own biographical account explains the search for a detector that combined the advantages of a dense target with visible particle tracks.[ref]
