Particle physics
Particle physics was a branch of physics dealing with subatomic particles and their interactions.

When Kes began to evolve in 2374, her body had initially gone into a state of cellular flux for a period of 17.4 seconds, and she began to destabilize at the subatomic level. Captain Kathryn Janeway approached The Doctor informing him that they needed to find a way to suppress it, and to further broaden their horizons in controlling it, stating that "this appears to have gone beyond medical science" and that "we're into particle physics now." The Doctor suggested that he would look through the quantum substructure database to see if he could find some inspiration. ()

The following year, the 29th century Borg drone named One had assimilated 47 billion teraquads of information from USS Voyagers library computer on a vast variety of subjects, including particle physics, comparative humanoid anatomy, warp field theory, and the culinary delights of the Delta Quadrant.
