Work

Normal matter consists of atoms possessing nuclei of protons and neutrons, surrounded by electrons. In a series of experiments conducted around 1970, Jerome Friedman, Henry Kendall, and Richard Taylor aimed high-energy electrons at protons and neutrons using a large accelerator. They studied how the electrons scattered during the collisions and how protons were sometimes converted into other particles. Their results supported the theory that protons and neutrons are composed of sub-particles, quarks.
