PORTFOLIO Bubble Tracks 1/4

About the images

Bubble chambers, invented in 1952 to image subatomic particles, are baths of liquid hydrogen in which charged particles split and combine, leaving bubble trails. Lines reflect the charge and momentum of newly formed particles; rotation reflects weight. Jonathan M. Dorfan, former director of the Stanford Linear Accelerator Center, says the photographs "store the entire content of what happens in the subatomic particle interaction."
