This edition: The Basic Building Blocks of Matter
In this unit, we shall explore particle physics, the study of the fundamental constituents of matter. These basic building blocks lay the foundation for all of the ambitious projects detailed throughout this course. Dramatic discoveries over the last century have completely changed our view of the structure of matter, as physicists have delved into the atom and deeper to discover the quarks and gluons inside the proton, have observed neutrino oscillations, and have carried out precise studies of the subtle asymmetry between matter and antimatter. The research has led to a detailed, if still incomplete, understanding of the most basic constituents of our universe.
