    Tracks made by atomic particles from a particle accelerator, a device that speeds up the particles. The eye can’t see protons, electrons, and other subatomic particles, but a camera records their frothy wakes in a chamber of liquefied neon and hydrogen at the Fermi National Accelerator Laboratory in Batavia, Illinois. Physicists study the tracks to learn about the characteristics of the particles that produced them.” - National Geographic, 1978.
