My talented roommate offered to revamp the background to my twitter page. She started off with some of my preferences: the colour blue, technology, and an organic feel. She and I were working together to add a little more character, when I suddenly thought of an image I loved so much as a physics student in high school.
This is an artistically enhanced picture of particle tracks in the Big European Bubble Chamber (BEBC), CERN, 1990. Detectors are used to measure properties of particles; some measure the tracks left behind by particles and others measure energy.
