The Standard Model of particle physics

Explore the elementary particles that make up our universe. The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make up the chemical elements, along with any other particles that cannot be broken down into any smaller pieces. The complete Standard Model took a long time to build. Physicist J.J. Thomson discovered the electron in 1897, and scientists at the...
